The consistency you have between the German and English versions of your content is impressive enough, but the fact you managed to get the cat to do almost exactly the same thing on both takes is genuinely next level 😂
I think his B-roll is all shared and in person are all differentiated.
The cat is a paid actor. It's all fake
I accidentally went to the German version first and noticed that too :p
I told Shiek she will get a extra tuna snack and she agreed
RUclips need multiple video/audio stream support
Paper: * exists *
The Cat: *So you have chosen... Death.*
@J M Hey mate. It's a fucking cat. Chill
@J M Infected cats only shed it once for a few weeks. And they're are inactive until 24 hours after excretion in poop. If the litter is cleaned before that, there is zero risk.
Besides, you can get it from meat, fish, goat milk, and lots of other things. It is completely harmless for healthy adults (unless you're immuno-compromised, ex: HIV).
And since you're already living with a cat, it isn't a problem for pregnant women either, as they need to be infected for the first time while pregnant for anything problematic.
TL:DR; Overblown.
@@helali_s interesting side note: Toxoplasmosis is linked to schizophrenia. But cats are adorable af so it’s worth the possible risk imo
@J M You're not going to get toxoplasmosis from a cat unless you eat it's poop. You're far more likely to get toxoplasmosis from not washing vegetables and not cooking meat properly.
Sixty-watt DIMMs? Holy crap. "Why isn't my PC booting? Oh, I forgot to plug the supplemental power cable into my RAM."
reminds me of the ram in my 2,1 Mac Pro with 32gb of DDR2 FB-DIMMs, under a memory activity heavy workload all 8 sticks can consume up to 90w.
@@thegeforce6625 fb DIMM runs ridiculously hot
@@virtualtools_3021 yup
This is what happens when you overclock your cat.
I started my computing career on System/38, the AS/400, i Series, System i etc. The hardware is way ahead of PCs. One morning we got to work and saw an IBM engineer waiting. He said iSeries had a cache failure, so it organised an engineer for itself. Cache was pulled out while it was running. The system said thank you on the console and configured itself for full speed. You get what you pay for :) Awesome.
my old Boss used to sit with the IBM engineer when they where getting data errors on the storage of the system/38 and make bets on exactly when it would fail, although that came during a time well before i worked there (i would have been in preschool at that time), when i started in the early 2000s they had the as/400 - iSeries which had been running for probably 7-8 years at the time, that thing was interesting to me and still to this day i hope to find a used one to add to my homelab/collection but the prices never go down. although the biggest thing i remember from back then was waiting 3hrs after work because i accidently knocked out power and had to wait for it to boot and display a login console on one of the 3180? terminals before i could go home (connected a large laser printer to a stupid unlabeled outlet on an extension cord that ended up being connected to the UPS the AS/400 and Novel 3.12 server where on, UPS did not like it and killed itself)
@@jjjacer That sounds like an amazing story right there, aside from the as/400 are there any other models that you really liked or stood out to you?
And then you've also got just how long IBM will actually extend support for their proprietary stuff like their POWER line of products. It's quite crazy that they support 4 generations of product at a time, both software and hardware.
great video as always, cute kitty
thanks for pointing out how mad IBM was back in the 2000s, i had a powermac quad G4 that i upgraded to 16GB, which made me a freak to my fellows then. lol
And then they pussed out of non big-iron applications.
The old IBM PCs from the 80s had enormous add-in boards for memory. If I'm not mistaken, they used ISA expansion slot, which is the grandfather of PCI, and later AGP and PCIe. The memory add-in boards where taller and longer than AIB 3080s/3090s. But to be fair, these memory add-in boards are not directly comparable to DDR DIMMs. But it's fun to see how small everything have gotten.
I was going to type the same thing. The ISA boards from the 80's were full length and were bracketed. Every time I see one of those sagging video card videos. I remember when those brackets became obsolete, somewhere around the time of 486 computers.
It is not the biggest. You should check other IBM D-DIMM modules for POWER10, that utilize IBM OMI interface. It is an evolution of Centaur / C-DIMM, to be more flexible, cheaper, faster (about 5ns, instead of about 10ns for Centaur) and higher capacity. They are enormous. Serial interface, with Microchip controller and mix of RAM (DDR4, DDR5, GDDR6 and HBM2) and Flash.
sounds like chimera of memory chips lol
Those have a WEIRD pinout.
@@Muscleduck looks like if a m.2 had a child with a sodimm on drugs
@@benuh5522 LMAO 🤣
I have some RAM from a Siemens 68040 based server, it used some 8MB RAM Modules that were as big as 1.5 - 2 hands.
I love odd computer hardware, IBM stuff has some romance to it.
Love 'em. IBM computers are stupidly tough and reliable, that most early PowerPC servers and mainframes can still be found today in excellent operational condition, no errors (although I would still recommend recapping the whole thing with new capacitors so you won't run into problem if they are over 10 - 15 years old - chips themselves are way overspecced for a very good reason so it would still work like new with replaced capacitors).
More cat
I remember having problems installing dimms with a big heatsink under my tower CPU cooler.. this is the superlative of that 😂
laughs in AIO cooler.
I love tech things, engineering in tech hardwares, cat, and modern room setups and atmosphere... Your channel has all things I like
The Dell R910 server used 8 risers for memory, each able to hold 8 standard DIMMs. I remember my first encounter with one. I was amazed how much memory it could hold.
Also, I worked on some old IBM p series machines running AIX, and they had these weird DIMMs (DDR2, iirc) that were almost twice as long as standard DIMMs, and some came with dual rows of ICs.
The oldest I worked on was a Data General the memory board was 400mmx 200mm, sometime I had to start it with a hammer on the fans when they got stuck.
1TB RAM max! The old Compaq Proliant 6500 could hold 8GB on its RAM daughterboard with registered EDO SIMMs, up to 32 of them.
Giving us the videos we didnt even know we needed. I like seeing random/obscure tech so these vids have been cool to watch. Thank you!
In the DDR1 era there were a lot of consumer motherboards that unofficially supported registered memory. The early 64-bit AMD chips are the best though, I have a socket 989 that will run 4x4gb dimms.
The cat was definitely the highlight of this video xD
Every video i watch ends up with me saying to myself "and I thought I knew much" well I never even knew about this type of hardware, nor have i ever seen memory modules of such massive proportions. Thanks again for the interesting content looking forward to more.
Always learn something new derBauer. Thank you for sharing.
I'm enjoying the technical breakdown of the POWER architecture you've been doing since that server showed up. I don't see much about POWER in my usual tech circles, so thank you. 👍️
Absolutely fascinating video! Whenever I look at the server market I'm absolutely amazed by just how innovative and advanced the tech can get, it feels as if its years ahead of our normal consumer space.
its so cool to see this exotic tech, very well done !
You'll love the POWER10 enterprise RAM modules with full, transparent encryption of everything in memory... ;)
this memory board alone is responsible for the worldwide chip shortage :-)
Seeing custom tech is always fun. Makes you realize how profitable the server market is when they're going out of their way to engineer such things in order to keep with their clients' demands
Lovely piece of video! It would be great to see those more recent IBM power servers!
Yeah, I would love to see that video!
OMG! the Kitteh! Love the videos in general but Shiek made the intro to this one special ...Good Job Shiek! Cheers! Stay Healthy and Stay Sane!
Your cat is a doll. Thanks for the smiles.
Some really fascinating DIMM space magic you've presented here! Some wild stuff that's not in reach of the average consumer.
Love this stuff thankyou, keen to see the next one
Fascinating content. Please do more rare parts. :)
I remember back in the '80's and '90's, RAM extender boards, where you stacked like 4 or 8 SIMM or SIPP modules, and plugged that into one socket on the main board.
IBM's Centaur chips were not exclusively found on massive proprietary DIMMs. The low end POWER7/8 systems had them installed on the motherboard themselves and had ordinary DIMM slots linked to each Centaur chip. It was a typical dual channel arrangement supporting up to two DIMMs per channel. That is likely why the IBM custom modules are so large as they're effective four DIMMs in one. Another note is that these DIMMs support ECC and IBM's ChipKill technologies so one DRAM chip can completely fail, be disabled by the Centaur chip and then continue operating while ECC is still maintained. I *think* those custom Centaur DIMMs could also be hot added to a fully running system.
The L4 cache of the Centaur DIMM does indeed function as a cache but its contents are restricted to the information of the DIMM itself. While it does improve performance, it mainly offsets the impact of using buffered memory. Adding more DIMMs does increase performance of these POWER7/8 systems even if memory capacity is kept at a constant. IBM did release both DDR3 and DDR4 version of these DIMMs and they are interoperable. However, there two different Centaur designs to deal with the different memory types.
POWER10 changes things significantly by using a common interface for multisocket communication and their memory buffers. Eight links are always dedicated to memory while an additional 8 can be used for SMP traffic or even more memory. It is pretty flexible so a single socket only system can have 16 TB of memory with a bandwidth of 2 TB/s which is very impressive. The big iron servers are only leveraging 1 TB/s of memory bandwidth and top out at 8 TB of memory per socket and upto 16 sockets in a single node. Memory sharing between nodes is also possible with the POWER10 but cache coherency is lost.
3D Xpoint memory or as it is more commonly known as from Intel as Optane, is a very interesting technology. Being byte addressable does permit it function as main memory. Intel initially was going to have Sky Lake-SP support these DIMMs but due to bugs had to disable that functionality. Similarly Intel was planning on permitting full Optane memory on its systems before requiring some DRAM to be installed. While the performance of Optane is slower than DRAM, it does permit some interesting potentials in software optimization: the full removal of the traditional storage stack as everything then becomes 'in-memory'. With enough capacity, those Optane DIMMs would double as both main memory and traditional SSD storage. This reduces operations like say loading a game into memory to zero because when you are not running that game, it is is already sitting in the Optane DIMM. Like a RAM disk but without the need for the traditional storage software layer to function.
love these kind of info vids... always been interested in new tech, different tech and well now "old tech" I remember looking into the RISC based CPU's back in the days since they "seemed faster" but they were expensive, not minded for "gaming" as I did back then (all the way since Dos, Windows 3.0 etc.) but I still look at the stuff (specifically the Sun Sparc's lately, they had a nice modular system that wasn't super big, that fit on the desk... which was amazing at a time when a desktop was GIGANTIC and for the time they were quite powerful and not running windows... but man those things are rare these days, hard to find a working one that doesn't cost a fortune
visiting and inspecting all those servers sounds HOT!! bring it on :D
i learn a lot today thanks for the video
I love those last minute edits being made to the notes at the beginning of the video! 😂
Amazing content! Can't wait for the visit to the server company.
Those must be some good notes you have there. Your cat won't let go of them.
There is so much more different types of technology that normal PCMR doesn't know about because it never made it to mainstream computers. It's very cool to see.
Very interesting as always.
I did learn, thank you!
10:52 Looking forward to 3DXpoint on PCIe 5.0 😁
this is awesome loved the intel hybrid
Pmem is just like an m.2 ssd (though closer to intel optane ssds performance wise) but in dram format instead of pcie.
It is useful for computers which need very large amount of storage and don't have pcie lanes available (for example iscsi/nas, database cache, geographical data...)
I always smile whenever I see Roman's Stargate address tattoo. :-D Here's hoping Amazon does some fans service with the license once they acquire MGM shortly...
Thanks for sharing, like it :)
We love your cat der8auer!! 💝
I work on mainframes, we still have System p (880), plus I also have some S814 servers, nothing more modern than POWER8 though. For me (I'm all about OLTP databases), anything after POWER5 was useless. I don't need SMT8 and huge caches, I need real IOPS instead :/ (x86-64 with NVMe is way better than pretending you have awesome ROI by running lots of databases on LPAR-s though VIOS, and it's cheaper, too :/)
But I'm fairly confident the SPARC boxes we've decommissioned few years ago had bigger memory modules than your biggest ones. Sun was so awesome before Oracle takeover, RIP Sun :(
I wonder whatever happened to jpkiwigeek :(
RIP Sun
I work in a government IT department (in the USA) and was sorting some really old surplus equipment a little while ago. I ran across some really weird DDR sticks that were double the height that had some other chips on board other than the DRAM. No idea what they were and unfortunately they were sent to the recycler. I'm curious as to what those were now...
There is little that makes sense, logically... other than something like a custom security / encryption chipset.
A:Why do you have a 1600W psu?
B:My RAM takes 400W
😆
DUDE I just noticed your Stargate address tattoo - LOOOOVE it.
i had to watch the intro 3 times cause i was invested on focusing on the cat lmao
I adore POWER -- I got full access to a POWER8 server a few years back to develop a homomorphic encryption system for some insurance companies. Lots of fun! Neat hardware.
More content like this please. Engineering is about relating a tool to a job. Not about trying to get another fraction of a percent out of shadow of the tomb raider.
why not both?
I already love this cat
Double height ram should make a comeback now we can have desktop class with 16 cores.
Thanks for the English version, must be annoying making 2 videos each time, love your content!
That's a lot of DRAM chips. I am kinda curious if it will also function on x86 processors other than Power 5 SOC that it originally was paired with.
With desktop RAM you often have a single row of ICs. in the server world, they're often stacked on top of each other for 20 IC on each side. Somewhat like laptop RAM, often times this is for fully registed dimms, but it could be for capacity
Computer: Single or Double-sided ?
IBM Centaur: Yes
Get it, Shiek! LOL You know, when I was a child, my teacher never believed me that my cat ate my homework. I wish I had RUclips back then. Shiek would have backed me up. LOL My childhood cat would literally place his paws on a piece of paper and then rip it up with his teeth. Usually to wake me up when I did not feed him early enough. To memory though! We are always hearing about how non-volatile RAM will change everything about computers. Still waiting... LOL Nothing changed for the PC. Servers ... some niche uses. But nothing huge either. What happened? And maybe just as important: what do you do when resetting the power doesn't reset the memory state and clear persistent errors?
beautiful big red cat!!
Very neat. I never knew those existed.
Upvote for cat. Your content is good.. but could never be as important as what the cat is doing :)
"Thats not a RAM stick...."
" *This* is a RAM stick"
With that person that was adding those DDR Raiser boards, and then with this chip. Woo-Boy that would be crazy
thats really amazing
love it. would be amazing to liquid cool all 8 of these and rgb ha
Again a good lesson
Very cool 👍
I see these dims on ebay a lot, if I remember correctly they are also used in IBM's Z mainframes or at least very similar modules.
Id love to learn a little more on how these non volatile ram sticks work in practice; in order to restore the system state after a power outage, I have to assume also the CPU registers and caches have to be stored somehow?
I'm a software dev and can imagine a nightmare scenario debugging a piece of code after validation testing passed and everything was already working for some months. And since these are semi-custom/special-purpose hardware, this would be truly a nightmare scenario.
thank you very much for making such an interesting video, i am very curious to know how much u spent to make this video.
G'day Roman & Shiek,
You started the video too early, Shiek hadn't finished Proof Reading the Data Reference Sheets 😸🥰
Ps WooHoo! Another Server Road Trip 😁
Who cares about hardware when you can watch a cat being playful and cute.
so geniune video with the cat messing him
niceeee
Haha, brilliant! Love her!
Thanks good video
That chip looks identical in size as the intel laptop chips
i have a msi gt62vr 6re dominator pro it 6 year old laptop i want to know can i overclock the cpu to 3.4GHz all core ? cause my temps only hit 60 at full load and and my cpu is stuck at 3.1 GHz there is not a single video to show how to overclock a i7 6700hq even when the option is given
This is one of the things I like about the PC market, the weird stuff DDR4--5 adapter
I have some ram sticks with 4 coin nimh cells which works as "nvram" (basically just keeps the ram powered on till the pc re boots), they were in a raid card.
Power9's are neat machines. I work on them alot and have 2 of them in my lab.
Wonder how those high capacity IBM sticks are wired electrically. How many connectors and what's the mem channel width. Probably a nightmare, lol.
There needs to be a way to re-purpose old ram or are they just not worth it?
" But there are even weirder sticks a lot wider "...... Do go on, I'm interested
what was AMAZING!!!! I knew of the NV RAM but didn't know of any details about it.... It would be hard for me to choose between the two types of NV you showed... either typical RAM speed but small capacity OR SLOW speed and VERY HIGH capacity..... I guess it really depends on the use case.....
BUT my favorite was the 128GB "stick" (maybe it should be called a 'plate' or a 'wafer' ..... no a 'sheet' ? no... a 'plank'?? YES!!) ..... my FAVORITE was that 128GB PLANK of RAM that was BIGGER THAN YOUR HAND!!!! HOLY SCHMOLY!!!!! I can't believe IBM still does this kind of stuff!!! HAHA!!! I used to get old SALVAGE computers when I was a kid (ok, it wasn't ME that got it, but my Dad had a friend) so I got to see ALL KINDS of HUGE Servers and ENOURMOUS PRINTERS the size of a stove top oven!!! With HUGE rolls of paper... But the servers... they would have the HUGE PCB's3 that were like 4 times the size of an ATX mobo ALL populated with like 64k chips and there would be like 25 of them inside the enormous case that took two people to wheel off the truck!!!
And so seeing that PLANK of a ram card actually TRIGGERED my memory of those servers!!!! I didn't remember them until I just watched your video!! WOW!!! THANK YOU!!! This is the kind of technology that fascinated me and got me into computers as a kid and now through my entire life!!! I just love weird tech lie this :D
will you have a future video on using CDIMMs on Consumer Desktop Motherboards?
IBM when anyone tells them that there are technology limitations: "Fuck it, I do what I want."
So cool
Where did you download this RAM?
Looking forward to the P9/P10 stuff, those servers are nuts.
will you be able to review the Power9 OpenPower motherboard by Raptor Computing as well?
Chrome: Finally, a worthy opponent!
LOL
I have a 21" Mac and it came with 8 GB, updating it myself is too risky because I will have to open the computer completely before I can reach the memory slots. Apple decided for some weird reason that it didn't need the usual memory slots in the bottom of the screen as my previous Mac 27" had. Is there a way to add extra ram using the USB ports?
No
“DUDE What if we made the whole thing D RAM?”
“DUDE!”
I need a Power 5 CPU for my collection. Also need a Core Memory Module to Complete my collection.
Love your Channel.
God Bless.
I learned a lot here. ☝️
This looks more of a meme than a real ram
Does this memory module even fit in a typical server rack? I am thinking 4U nothing less
That cate is soo cute😂😍
