My entire rack runs around 600watts, 24hrs, 7days.. Including my modern 11th gen desktop with GTX1660 video in it. Pretty good considering what I have in it, the solar helps offset the cost, but there is a cost involved with that as well. Great video.
I got suckered into solar. It saves me about $100 during the hottest times of the month, but the system costs about $300 a month. So my savings are -$200 over what my electric bill used to be. Supposedly they were giving me a bigger system than I needed. Absolute bullshit! Never trust a solar salesman. What they promise and fail to deliver on should be criminal.
@UnkyjoesPlayhouse Cool. thanks for sharing! I don't think I would run a home server lab if I didn't have solar in CA. I imagine TX energy costs are a bit lower.
Yikes. Yes you definitely need solar to offset that. Right now my entire house (UK daytime) is running at 306 watts. That includes my IT home lab, 1 desktop PC, 2 x mini servers, router, the works. And 2 laptops running idle. With current energy prices in the UK I couldn't justify 600W just for my IT. A shame because I would like to run a single more powerful server.
Grateful for such a nice clear overview of the actual power consumption. This machine can also be configured with 512GB memory e.g. to use as a ramdisk instead of putting temp files on an SSD, as most consumer SSDs have limited endurance.
In the UK 200w will be 55 USD a month 🙂 I used to run a T440 and a T420 and home and now just have a little Lenovo m90s i5 with Intel AMT. Electricity cost has gone crazy over here!
the whole country's gone crazy over there. nothing on the shelves, collapsing health services and insane, unjustified and not based on reality prices and bills.
Yes but my 2015 computer, at 22nm, keeps my room warm, and uses less electricity than an electric heater. So it's a computer & A heater in one! 'Winter is coming'! 😂
The power consumption of my HP z420 with a single E5-2697 v2, 4x32GB dimm, 7 drives (4x 7200rpm, 1x5400 rpm, 2x sata SSD) and 1 dual-port nic is about 105W. I love how modular Z workstations are. With my configuration, I have 4 ram slots left, so technically, I could reach up to 256GB with a single CPU!
I bought a Z840 which I'm waiting for. I have dual 10 core 85w TDP CPUs. Someone ran the numbers on low vs high power CPUs in file server machines. Once you figure in the energy used for the drives the CPU isn't a huge issue. As you say, the power does a lot of good work for you.
I had a Z820 for several years. I used it until a year or two ago and got rid of it this year. It is pretty hot and noisy. You have to add the cost of air conditioning to that because of the heat it puts out. I had a Z820, four Z620s, and four Z420s. Running them all was about like having a hair dryer running all of the time.
I'm guessing you had high performance CPUs? If you run the energy efficient low power CPUs, it would probably be better. But these days, I think Broadwell might be a better value choice.
My Dell R815 with 4x Opteron 6380, 128GB ram, 6x drives uses around 200 watts idle, 450 when doing moderate things, and near 700 watts if I do something silly like max out all 64 cores. I run a bunch of VM's on this machine, but I don't have it on much. my 24x7 box is a Intel i9-9900T box with 128GB ram on an industrial Asrock MB, and it uses around 15 watts idle and less than 75 when doing stuff. Cheers!
I run two Z840s both with dual processors. At idle they consume close to 300w combined. Definitely could replace one of them with something less powerful (its my Truenas server) but then I'd have to spend money. The other is my Proxmox hypervisor so it makes sense having the dual processors. These were free so Im rocking them till they die.
Thanks for the excellent channel, the HPz820 is the machine that I am having trouble with the hdd unit hitting the dramm slots. I do have a method to make for a cleaner cut for the drive cage. You have inspired me to start a channel as well. Thank you sir.
I had a Z620 2x E5-2640v1 CPU, 5x SSD and 2x HDD, GT1030 and 192GB..all running ESXi and it would consume around 250W running all my workloads. I recently moved to a Dell T440 with 6148 Gold CPU, 256GB, 8 SSD an 1 x HDD...all for 150W avg running the same workloads under ESXi. That's a saving of 876 Kw/h per year or around £260 per year for me for a server which is massively more powerful.
Is that a workload you run constantly all year round? I would expect SandyBridge -> Skylake Xeon to be a significant energy efficiency improvement. Even from SandyBridge to IvyBridge was a decent improvement going from 32nm to 22nm, and especially Haswell/Broadwell (14nm). Skylake remained at 14nm.
Considering the price human consumables, such as a lunchtime coffee and muffin at well known coffee shop chain, 24 hours of useful power for a HP Z820 is a bargain by comparison.
i was able to get my Z840 with 28c/56t 256GB and a bunch of disks and 10G net to drop from about 450W 24/7 down to like 360W by dropping VMs that I wasn't using everyday and by reducing the CPU counts and RAM usage on the VMs that were running where I could so that each core that WAS used was being more thoroughly used...it made more of a difference than i had expected it would honestly. i also set my backup server to only turn on once a day, run rsync, then turn back off 5 minutes later and thats saved a TON or power from that thing idling all day just keeping a backup
~160W idle with no drives is quite frankly ludicrous, both in terms of cost and heat. For context, my R730 idles at about 75 watts (less than half of this monstrosity), and it has dual E5-2650 v4 CPUs (which score ~13% higher multicore and ~17% lower single core than 2687W v2), 16 DIMMs, two SAS SSDs, a PM1733 U.2 NVMe, and four M.2 NVMe drives in an x16 bifurcated adapter. The Z820 is cheap, up front, but power and cooling costs over even the short term kill any value proposition. Also, these CPUs aren't even that quick; CPU competition in the last few years has really moved the game so far forward it's funny.
For heavy compute loads, v4 Xeons certainly are more efficient than v2 generation. However, that's not every use case. I have started to use a Z820 as my home desktop/gaming PC. The highest I've seen it draw (yes there's a Kill-a-Watt on my UPS) is 340W while playing a shooter game, and my nVidia 3060 is probably responsible for much of that. Cooling costs only if you run an air conditioner, which right now I am not. A replacement would cost at least $1000. Since my electric bill is about $70/month, it would take a few years to pay for itself.
Pretty sure most of single socket DDR4 Ryzens will be "drastically" better here. But even as old as Skylake usually gives a giant generational improvement in efficiency. And if we are talking 24/7 homelab efficiency than running multisocket vs multiple machines was always a pitfall. I'm thinking something like 2x E5-2687W (2x 12'161 passmark 16c32t) vs 2x Ryzen 5600X (2x 21'937 passmark 12c24t) would "drastically" destroy it in everything, 100% load, 5-10% typical homelab load, PCI-E lanes, flexibility.. I never had Ryzen yet (still in a good place with all my 1151 sockets for now), but their real-world consumption figures are remarkable, both loaded and idle.. and looks like my future homelab is headed that way unless something else comes up.
I built my son a new computer earlier this year based on Ryzen 5900x, and although it is a great machine, the power consumption was not drastically better. It was certainly an improvement, but not what I would consider drastic. On top of that, it was slightly slower than my Z840 for rendering 4k videos. I'm sure the 5900x is faster at many other things, but benchmark numbers don't always tell the full story.
@@ArtofServer I commented on this in that video. As to power consumption, most distributions come with all powersaving features unused by default and it is quite an effort to achieve anything near to what Windows is capable of with minimal tweaks.
My Z840 is my daily work machine, so it's plugged in at my office. The business pays the power bill and there are more wasteful machines plugged in in our labs, so for me this is really not a big deal. If I bought a new "modern" machine with the same specs (256 GB of RAM, tons of drives, big CPUs, GPUs for AI work) it would cost me $10K easily. The cost of the power over time is lower than that given the new machine would still use a lot of power.
12490+rx580 only get 80wats power consumption. But the cpu is way faster than e5 ones. I thinks there is no necessary to choose e5 cpus for normal task. Except for the ecc memory and pcie lans.
Dell SC8000 which are the corresponding generation hardware (a la Dell R720), used Xeon E5-2640 v1. The E5-2667 and E5-2670, 2680, 2690 are also interesting CPUs which should be far cheaper than the E5-2687W.
Yeah, there are definitely options to lower the power consumption of this machine if the use case doesn't require the faster CPUs. A NAS only use case certainly could go with one of the "L" CPUs from the E5-2600v2 generation. BTW, there's some power savings to be had by upgrading the v1 CPUs to v2. And the v2 CPUs are very affordable these days.
San Diego here . between 39 cents and 82 cents per kWh depending of the time of the day. So with approx 5 kWh per day you looking between 60 and 120 $ per month not taking for the consideration basic allowance which id 650kwh / month and if I go above the price of each daily tier goes up.
@@MOTOSTAN Small (big?) correction. Here in CT they charge almost 3 times the power consumed for delivery so my rate would be closer to 90c per kWh if I used the damned thing. Can switch back to the grid in an emergency but haven't done so in 3 years.
I pay 12 cents per kWh residential, 9 cents industrial. I don't know how the hell anyone is paying 90 Cents in the States. It's cheaper to buy diesel at $4 a gallon (40 kWh total heating value), burn it in a generator at max load, invert it from AC to DC for battery buffer, convert it from AC back to DC via inversion, and still would be less than 30 cents per kWh! Calculation: 40% efficiency at 80% load from diesel fuel to 240 V AC 60 Hz output -> 97% efficiency AC-to-DC 48 V conversion via inverter to charge LiFePO4 battery bank with 95% discharge efficiency - 97% efficiency DC-to-AC conversion via inverter to 240 V AC 60 Hz output -> 40% * 97% * 95% * 97% = 35.754% end-to-end, round-trip efficiency.
These are great computers. Your configuration is very nice. I am looking to buy one as well, just shopping price vs config on ebay from the resellers. I would put a Nvidia 1080 in mine for some gaming as well. I did look at Dell PowerEdge servers and like them as well, but since I don't have a rack and you can't put a large graphics card they are probably out for me now. Now I am curious about how much power my old SGI Indigo2 workstation consumes.
Dude! I used to have an SGI Indigo2 as well! (and a lot of other now obsolete machines) Yeah, really love the Z820, but I would suggest also looking at Z840 also. Both are great.
So Basically, a server using 250W continuously costs about a $1.25 a day to run after taxes and fees. Boy, I am SO GLAD all of the NEW power plants are Being built... I mean I LOVE that it costs so much more to make power from HYDRO in the PNW....
Very informative. Thank you for sharing your time with us. I haven't searched your video library and was wondering if you had run same / similar tests on modern machines that use single / dual Intel i7 or i9 CPU's
Glad you liked this. I don't often use consumer PC hardware, so you're not going to see much i7 / i9 related stuff on my channel. It's mostly going to be Xeons and server gear.
@@ArtofServer Understood. I came very close to picking up a Dell Poweredge R720 this past weekend but re-considered. I need something with a smaller footprint in a tower format given that this will serve as my homelab. The Z820 is looking very promising thanks to your presentation.
So strange that a z820 can run a v2 CPU but a z640, the next gen computer couldnt until the later boot block version came out. They're good computers though. Using a z4 g4 and Lenovo p520 now and they are quite good. I like the Lenovo better though I'd say. It has a better heat sink, larger case and is built better IMO. It also has 2 NVME slots which is nice.
The Z820 did require certain boot block to support v2. There was not straight forward method to update older boot block motherboard to support v2. Although, i recall seeing instructions on programming the chip directly, I've never tried it. Some had success converting those boards. The Z640 generation (e.g., Z840, Z440) was a new platform that supported the v3 and v4 Xeons, and there was no issues in that case upgrading from v3 to v4 CPUs. I'm interesting in trying out a Lenovo P920 workstation, but have never had one.
I'm running a truenas server on a HP Elite 8200 CMT, close to 60 watts on idle with 5 drives, just down want to use that much energy 24/7 so I only use it for backing up my proxmox host. nvm 200 watts.
Interesting. Especially that everyone says CPUs don't consume much when idling, regardless of top performance. Apparently, it's not true. I would have expected such a setup to idle somewhere between 80-120W without the HDDs. 200W is surprising.
Well, keep in mind that this is an Ivy bridge xeon. Idle efficiency was much improved in the next generation Haswell/Broadwell Xeon and beyond. Thanks for watching!
Just checked my 128G AMD Ryzen 7 5800X 8-Core desktop that has 1 sata drive and 2 nvme drives in addition to 2x 32" 4K monitors and an always on THX audio system + Radeon XFX 7900. 273 watts total draw at idle. Running Ubuntu 22.04 fwiw.
Thanks for sharing that. Wow, that's higher than I thought it would be based on the specs. Does that include running the 2 monitors? What happens if you turn off the monitors?
@@ArtofServer Yes, the power consumption includes the monitors and the THX Audio system. Let me try turning them off ... Without the monitors the draw is 140W. Jumps up quite significantly if I have the 24G video card cranking and all cores on full tilt.
I have a Dell T710 with two E5-2690 V4 and 128gb of 2133 DDR4, my power consumption at idle is about 70 watts. I think moving from V2 (32nm) to V4 (14 nm chips) might help.
I would call it proprietary .... but it is possible to "adapt it". If you're someone who has no problem dropping a different engine into a car, then you will have no problem making the adaptations. I will just point out that HP uses a different standby voltage for whatever silly reason, so if you adapt the power connection from the PSU, make note of that.
My friend wants to buy a g10 server, for 2d/3d rendering with 3dsmax to fire his g5s, is it better the rack dl380 g10 or the tower? He does not have a rack but he has not too much space
I recommend to your friend to get a non-HP server. Dell or Lenovo perhaps, and maybe even supermicro. Choose a brand that has abundant parts in your region of the world, but not HPE.
@@leonardotoschi585HP has some DRM (I can't recall what) that might make it less desirable than the other players. SuperMicro has the least locked down BIOS and it is easy to modify/hack if you want new features. You are also not limited to using proprietary fans like the HP or Dell most likely.
@@NUCLEARARMAMENT My friend took a lenovo SR650, but i'm not a big fan of supermicro. I would prefer Lenovo/IBM over supermicro, just for the fact that supermicro is too "open", is a mess getting the right chassis (often 3 or 4Us) with the right rails for the right motherboard, and the servers they sell like the 2us are only for special applications like super storage or gpu clusters.
there's several videos where I show how I got that installed in the Z820. it's a bit of a pain... so check those videos out before you decide to do it.
That's true. But in many cases, unless you're running a public cloud server, most of that doesn't matter. In most cases, these are homelab machines, usually not exposed publicly.
I think you misunderstood. Those mitigations make the cpu slower. I have no experince with it myself, but there were news articles claiming large percent performance loss each time an exploit was patched. You can view it as an extra electricity cost, since the cpu has to work more.@@ArtofServer
I would imagine so, especially at idle. Under constant I/O load, there might be less of a difference depending on the model of SSD. Some SAS-3 SSDs can really heat up and use power under heavy load.
@@ArtofServer in my experience under load they actually draw a bit more (really the cpus do) because they are getting “fed” more however it’s like they can do all the work in a tenth of the time so your still net positive
with SSDs you would save all the watts, because they actually may consume next to nothing at idle while with HDDs it is like (per spindle) ~6-7w avg homelab NAS / SOHO use vs idle ~5-6W which is all to keep platters spinning at constant RPM.
@@ArtofServer yeah I already did, I got server from work some years ago, it had a dead pcie slot, was more server than what I needed with 2x e5-2470v2 and six sticks of ram per CPU, 192gb of ram total. Running a consumer grade system now, I don't really need ecc or 40 threads to play with, was fun though learning with it.
hello, i wonder if you can help me. i cloned my operating system(win 11pro) on a nvme 2tb to be placed in my HP Z820. for some reason i won't boot up to my OS. i went into the bios and tried to change the boot up option and NOTHING. Does this motherboard supports nvme as a main boot up disc. THANK YOU.
There are 2 factors at play here. 1) windows is very specific about the drivers for the boot drive. If the system tries to boot but blue screen, it's probably because you don't have the driver necessary. 2) the ability to boot NVMe on the Z820 is literally answered in this video. ruclips.net/video/PrZEYkNl9aI/видео.html
I'm setting up an HP Z840 with dual Xeon E5 2690 V4 as a server with Proxmox and need advice on what GPU to get, this server will be used for VMs and virtualized a Truenas setup
Hi 👋 I have a Z800 with an Nvidia 2080. The performance is completely sufficient for games and various applications. I don't care about the power consumption because I don't work on it every day and all the time. The only problem apparently with Intel xeon: Nobody tells you that VR glasses are not supported!!!

@@ArtofServer I commented on this in that video. As to power consumption, most distributions come with all powersaving features unused by default and it is quite an effort to achieve anything near to what Windows is capable of with minimal tweaks.
My Z840 is my daily work machine, so it's plugged in at my office. The business pays the power bill and there are more wasteful machines plugged in in our labs, so for me this is really not a big deal. If I bought a new "modern" machine with the same specs (256 GB of RAM, tons of drives, big CPUs, GPUs for AI work) it would cost me $10K easily. The cost of the power over time is lower than that given the new machine would still use a lot of power.
The Z840 should be even more efficient than the Z820 in this video. It should be very reasonable, considering what you can get out of it.
Interesting to see how much power it takes under load. I can run my entire house on about 500kWh alone 😄
Amazing!
Good morning. Thanks for info.
Good morning! Thanks for watching!
12490+rx580 only get 80wats power consumption. But the cpu is way faster than e5 ones. I thinks there is no necessary to choose e5 cpus for normal task. Except for the ecc memory and pcie lans.
I always need more PCIe lanes. Main reason why I don't like consumer PC hardware.
Dell SC8000 which are the corresponding generation hardware (a la Dell R720), used Xeon E5-2640 v1. The E5-2667 and E5-2670, 2680, 2690 are also interesting CPUs which should be far cheaper than the E5-2687W.
Yeah, there are definitely options to lower the power consumption of this machine if the use case doesn't require the faster CPUs. A NAS only use case certainly could go with one of the "L" CPUs from the E5-2600v2 generation. BTW, there's some power savings to be had by upgrading the v1 CPUs to v2. And the v2 CPUs are very affordable these days.
9.35 cents per KWH here I need a supplemental heater in the Winter
25 cents here. I'm 100% on Solar now.
San Diego here . between 39 cents and 82 cents per kWh depending of the time of the day. So with approx 5 kWh per day you looking between 60 and 120 $ per month not taking for the consideration basic allowance which id 650kwh / month and if I go above the price of each daily tier goes up.
My cats loved the warmth of my computers, especially in the winters.
@@MOTOSTAN Small (big?) correction. Here in CT they charge almost 3 times the power consumed for delivery so my rate would be closer to 90c per kWh if I used the damned thing. Can switch back to the grid in an emergency but haven't done so in 3 years.
I pay 12 cents per kWh residential, 9 cents industrial. I don't know how the hell anyone is paying 90 Cents in the States.
It's cheaper to buy diesel at $4 a gallon (40 kWh total heating value), burn it in a generator at max load, invert it from AC to DC for battery buffer, convert it from AC back to DC via inversion, and still would be less than 30 cents per kWh!
Calculation: 40% efficiency at 80% load from diesel fuel to 240 V AC 60 Hz output -> 97% efficiency AC-to-DC 48 V conversion via inverter to charge LiFePO4 battery bank with 95% discharge efficiency - 97% efficiency DC-to-AC conversion via inverter to 240 V AC 60 Hz output -> 40% * 97% * 95% * 97% = 35.754% end-to-end, round-trip efficiency.
Just to add I removed one of the cpu's (same as your one) from my Z820 and it reduced the idle by 25-30w
These are great computers. Your configuration is very nice. I am looking to buy one as well, just shopping price vs config on ebay from the resellers. I would put a Nvidia 1080 in mine for some gaming as well. I did look at Dell PowerEdge servers and like them as well, but since I don't have a rack and you can't put a large graphics card they are probably out for me now. Now I am curious about how much power my old SGI Indigo2 workstation consumes.
Dude! I used to have an SGI Indigo2 as well! (and a lot of other now obsolete machines) Yeah, really love the Z820, but I would suggest also looking at Z840 also. Both are great.
@@ArtofServer Good suggestion on the Z840. I checked the power consumption on my Indigo2 solid impact, and it was 168watts.
So Basically, a server using 250W continuously costs about a $1.25 a day to run after taxes and fees.
Boy, I am SO GLAD all of the NEW power plants are Being built...
I mean I LOVE that it costs so much more to make power from HYDRO in the PNW....
That's why I got solar panels 😀
Very informative. Thank you for sharing your time with us. I haven't searched your video library and was wondering if you had run same / similar tests on modern machines that use single / dual Intel i7 or i9 CPU's
Glad you liked this. I don't often use consumer PC hardware, so you're not going to see much i7 / i9 related stuff on my channel. It's mostly going to be Xeons and server gear.
@@ArtofServer Understood. I came very close to picking up a Dell Poweredge R720 this past weekend but re-considered. I need something with a smaller footprint in a tower format given that this will serve as my homelab. The Z820 is looking very promising thanks to your presentation.
Good video !
Glad you enjoyed it
So strange that a z820 can run a v2 CPU but a z640, the next gen computer couldnt until the later boot block version came out. They're good computers though. Using a z4 g4 and Lenovo p520 now and they are quite good. I like the Lenovo better though I'd say. It has a better heat sink, larger case and is built better IMO. It also has 2 NVME slots which is nice.
The Z820 did require certain boot block to support v2. There was not straight forward method to update older boot block motherboard to support v2. Although, i recall seeing instructions on programming the chip directly, I've never tried it. Some had success converting those boards.
The Z640 generation (e.g., Z840, Z440) was a new platform that supported the v3 and v4 Xeons, and there was no issues in that case upgrading from v3 to v4 CPUs.
I'm interesting in trying out a Lenovo P920 workstation, but have never had one.
I'm running a truenas server on a HP Elite 8200 CMT, close to 60 watts on idle with 5 drives, just down want to use that much energy 24/7 so I only use it for backing up my proxmox host. nvm 200 watts.
yeah, i guess it depends on your local energy costs, that will affect perspective.
Interesting. Especially that everyone says CPUs don't consume much when idling, regardless of top performance. Apparently, it's not true. I would have expected such a setup to idle somewhere between 80-120W without the HDDs. 200W is surprising.
Well, keep in mind that this is an Ivy bridge xeon. Idle efficiency was much improved in the next generation Haswell/Broadwell Xeon and beyond. Thanks for watching!
My Dell R720 with 2x 2690 and 8x hard drive idling at about 190W. But without a GPU
not bad. not bad.
Just checked my 128G AMD Ryzen 7 5800X 8-Core desktop that has 1 sata drive and 2 nvme drives in addition to 2x 32" 4K monitors and an always on THX audio system + Radeon XFX 7900. 273 watts total draw at idle. Running Ubuntu 22.04 fwiw.
Thanks for sharing that. Wow, that's higher than I thought it would be based on the specs. Does that include running the 2 monitors? What happens if you turn off the monitors?
@@ArtofServer Yes, the power consumption includes the monitors and the THX Audio system. Let me try turning them off ... Without the monitors the draw is 140W. Jumps up quite significantly if I have the 24G video card cranking and all cores on full tilt.
I have a Dell T710 with two E5-2690 V4 and 128gb of 2133 DDR4, my power consumption at idle is about 70 watts. I think moving from V2 (32nm) to V4 (14 nm chips) might help.
Actually, the E5-2687W v2 is based on 22nm, not 32nm. But of course, going to 14nm would definitely improve efficiency.
Is the internal hardware propriety or can you remove it and switch it out with off the shelf ATX hardware? I really like the case which is why I ask.
I would call it proprietary .... but it is possible to "adapt it". If you're someone who has no problem dropping a different engine into a car, then you will have no problem making the adaptations. I will just point out that HP uses a different standby voltage for whatever silly reason, so if you adapt the power connection from the PSU, make note of that.
How did you get the 4-bay HDD kit for mounting hard drives from the front? Thanks!
That was covered in previous videos. See the full playlist here:

My friend wants to buy a g10 server, for 2d/3d rendering with 3dsmax to fire his g5s, is it better the rack dl380 g10 or the tower? He does not have a rack but he has not too much space
I recommend to your friend to get a non-HP server. Dell or Lenovo perhaps, and maybe even supermicro. Choose a brand that has abundant parts in your region of the world, but not HPE.
@@ArtofServer why?
@@leonardotoschi585HP has some DRM (I can't recall what) that might make it less desirable than the other players.
SuperMicro has the least locked down BIOS and it is easy to modify/hack if you want new features. You are also not limited to using proprietary fans like the HP or Dell most likely.
@@NUCLEARARMAMENT My friend took a lenovo SR650, but i'm not a big fan of supermicro. I would prefer Lenovo/IBM over supermicro, just for the fact that supermicro is too "open", is a mess getting the right chassis (often 3 or 4Us) with the right rails for the right motherboard, and the servers they sell like the 2us are only for special applications like super storage or gpu clusters.
👍👍👍👍
Thanks.
What's the part number / name of the top disk rack you've got? The one where the disks are arranged on their side.
Looks like the icy dock according to the links in the description. Nice. I may pick one of them up!
there's several videos where I show how I got that installed in the Z820. it's a bit of a pain... so check those videos out before you decide to do it.
lscpu shows it is loaded with mitigations. That's another hidden cost for an old cpu.
That's true. But in many cases, unless you're running a public cloud server, most of that doesn't matter. In most cases, these are homelab machines, usually not exposed publicly.
I think you misunderstood. Those mitigations make the cpu slower. I have no experince with it myself, but there were news articles claiming large percent performance loss each time an exploit was patched. You can view it as an extra electricity cost, since the cpu has to work more.@@ArtofServer
if SSD's are used I'm imagining you would save 30+ watts?
I would imagine so, especially at idle. Under constant I/O load, there might be less of a difference depending on the model of SSD. Some SAS-3 SSDs can really heat up and use power under heavy load.
@@ArtofServer in my experience under load they actually draw a bit more (really the cpus do) because they are getting “fed” more however it’s like they can do all the work in a tenth of the time so your still net positive
with SSDs you would save all the watts, because they actually may consume next to nothing at idle while with HDDs it is like (per spindle) ~6-7w avg homelab NAS / SOHO use vs idle ~5-6W which is all to keep platters spinning at constant RPM.
My duel socket LGA 1356 server consumed almost double that thing at idle without disks lol
Ouch! Time to upgrade! Lots of used server/workstation prices are dropping so might be time too.
@@ArtofServer yeah I already did, I got server from work some years ago, it had a dead pcie slot, was more server than what I needed with 2x e5-2470v2 and six sticks of ram per CPU, 192gb of ram total. Running a consumer grade system now, I don't really need ecc or 40 threads to play with, was fun though learning with it.
hello, i wonder if you can help me. i cloned my operating system(win 11pro) on a nvme 2tb to be placed in my HP Z820. for some reason i won't boot up to my OS. i went into the bios and tried to change the boot up option and NOTHING. Does this motherboard supports nvme as a main boot up disc. THANK YOU.
There are 2 factors at play here. 1) windows is very specific about the drivers for the boot drive. If the system tries to boot but blue screen, it's probably because you don't have the driver necessary. 2) the ability to boot NVMe on the Z820 is literally answered in this video. ruclips.net/video/PrZEYkNl9aI/видео.html
no, there is no blue screen of death, it just reads. non-system disk error. THANK YOU.
I'm setting up an HP Z840 with dual Xeon E5 2690 V4 as a server with Proxmox and need advice on what GPU to get, this server will be used for VMs and virtualized a Truenas setup
What do you need the GPU for?
If I need to connect a monitor to the server to look at the Proxmox console
Also if I need to perform a bios update and other tasks that may require to connect a video output
How did you install zfs on fedora? I a. Running silverblue and have been unable to get it to work🤔🤔🤔

i run dual sandy bridge cpus in my server but i only power on my server when i need it so not to worried about power
That's great!
Check how much fans are consumming power ;)
LOL. This thing does have a ton of fans!
@@ArtofServer check fans to cooling disks. 12V 1.2A? It's 14W of power. Per each fan ;)
what about the Z840 then ?? :)
for future video.
Hello. I managed to get a computer HP z800 for a good price. but at home I only have amd vega 64 tossed around. will he support amd cards?
i don't know. give it a try.
Hi 👋
I have a Z800 with an Nvidia 2080. The performance is completely sufficient for games and various applications.
I don't care about the power consumption because I don't work on it every day and all the time.
The only problem apparently with Intel xeon: Nobody tells you that VR glasses are not supported!!!
How so?
@@ArtofServer: A certain command set is not supported.
Where did you get that 4 drive front mount? Reply at my channel. Thanks!
I'm assuming you're talking about the 5x drive Icy Dock unit? That was a fiasco... but documented in these videos:

The Problem with HP “Z” class workstations is that HP puts a Terabyte limit on these computers. Like the HP z220 only supports 4tb hard drives.
That's not true at all. I have filled these machines with 16TB drives without any issues. Please don't spread misinformation.
