Let me know what you would like to see tested next! Even if it sounds ridiculous, it'd probably make for solid content at the Verge's expense LOL.
- 3200 MT/s with the sharpest possible timings (Samsung B die, CL=14) vs. 3466 MT/s with mediocre timings (lesser die, CL=16) for Ryzen.
- Windows vs. Linux performance for cross platform benchmarks. See Phoronix and Hardware Unboxed (Threadripper and Xeon in the case of HU).
-TR 32C vs Epyc 32C (quadchannel RAM), probably not possible for you but if it would ever be possible...
How many frames were used for that title regarded comment of yours?
How about dual channel vs quad channel? Productivity apps which do not matter if your system has dual or quad channel?
Hi. If 3 identical sticks are used, would it still run in dual channel mode? Or for instance 2 sticks a1,b1 but different capacities? Interested for setting up 12GB system configs.
Actually interested only in knowing the 2 stick config, 8+4 gigs. Would it run in dual channel and what problems i could face? Assuming i use the same manufacturer, same timing and speed sticks, just different capacities.
@@AlfaPro1337
I suggested the same. He probably doesn't have a Threadripper system yet. You can buy an old Xeon CPU on the cheap but finding an affordable motherboard for it can be a hassle.
Get your hands on a threadripper CPU and motherboard to do quad channel memory testing, and redo all the testing for dual and single channel on the TR setup so we can compare properly. The first gen threadrippers can be found for fairly cheap now too, I'd be all over that video tbh

I'd been running in single channel until the whole The Verge thing, since I'd switched from a board with 2 slots to 4, and just putting my sticks in the first two slots... Switched 'em to dual channel after that though. XD
The verge said something else idk what to believe
Clearly NOT the verge
Braden Sweeten you should trust the verge because they used a fancy cpu application tool. Clearly they know what they are doing.
@@azizx2796 They didn't use it though.
@Nacho Ruiz Plz don't make it worse than it already is. I get cancer from this every single time i remember that video
The verge is made fun of everywhere tech wise
So
The answer is clear
Choose geico
Literally ordered a second stick minutes before watching this video, I guess it was definitely a good idea! I also needed more since I was on only 4gb. Now I'll be 2x4gb ddr3 1600 for my Ivy bridge system. I've also seen even on ivy bridge i5's that frequency can make quite a difference in performance.
I used to have one stick in my slots when I first moved to DDR4 because of the price of it and noticed a drop in frames from my rig that used ddr3. I didn't realize it was my ram until I did some research on youtube and found that when I did end up purchasing a second stick of memory my frames improved a crazy amount, it was like getting an entirely new PC, I don't remember the margins that were there but they were similar to the ones in this video. To anyone thinking you will be just fine or trying to save money by purchasing just one stick, please try and get another one if you can, it will help you immensely.
Steve (from Gamer'sNexus) disagrees. Unless you have an integrated GPU, games are rarely bottlenecked by memory bandwith. It's more likely you didn't have enough memory to begin with.
Well that was a noob mistake. You buy them in pairs and install it in pairs.
@@eagleeye8916 Keep in mind, that the more DIMMs you have in your PC, the harder it will be on the memory controller. Especially, if you have dual rank memories.
I had 2*4Gb 1866 Mhz dual rank Corsair memory installed in my PC. A few years later I bought 2 more module, but the FX's IMC can't handle that speed with 4 module, and I had to downclock my memory. With a little overvolting and playing with the BCLK, I managed to pump it up to 1800 Mhz, but it's borderline unstable.
*My advice*: If you can't or don't want to buy 16Gb memory, get a single stick of 8 Gb, preferably single ranked module of a popular brand. It will cause you less headache, when you have to upgrade your memory capacity.
@@TheGyuuula 16gb ram (2x8gb) is the minimum for a gaming pc going into 2019. They can range from $100 -200 depending of brand and speed. Extra ram is usually for photo editing , animation , video editing etc. They should be able to afford it being the hardware for that platform is in another premium price point by itself . Like how I bought pairs of 2x4gb for an older MacBook pro . If I was short it take me the next pay check which only cost me like $60 at the time
@@eagleeye8916 wrote: "They should be able to afford it"
It *depends* :D Here in East-Europe, a modern gaming PC (~1000$) is quite a luxury. People would rather spend it on a used car or something practical. Or think of a student on a tight budget. If you have to skim on the memory, buy a bigger capacity module - rather than 2x half the size - and buy a second module later. I think for AAA games, 16Gb might not suffice in just 1 or 2 year. So, staaay awaaay from the 4Gb parts.
Merry Christmas to you too! Nice video. Anyone involving with PC building knows that dual memory is a must. But for newcomers to the subject those videos are useful.
Love your vids,been watching em for a while,i reached a better understanding of computers!
One thing that you did not cover, is that each memory channel requires a fixed amount of time to complete a memory transaction. That time windows is determined by the frequency and the ram timings set in the bios. If the memory channel is operating in its request access window, it cannot service other requests . the end result is that teh CPU is sitting in an idle state waiting for the next chunk of memory data to arrive before it can process the next frame to send to the GPU
Dual channel and to a larger extent quad channel, allow the PC to interleave memory requests. That means make requests in parallel. a single channel can only do one thing at once but dual channel can service two requests at teh same time. quad channel memory services 4 at a time. the extra data arriving at the CPU gives the threads more things to work on and as a result spend less time sitting idle.
Apps like cinebench get all ist memory data up front and everything runs out of the cache during the benchmark. The CPU does not need to request memory from the System ram after it starts running. That is why Ryzen performs so well at cinebench.
Games, for the most part, force a CPU to rely on a regular cadence of fresh memory data deliveries to process the next set of instructions that can be sent to the GPU before it can render a frame. If the CPU is idle waiting on data because the single channel requires 75ns to deliver the data packets from System Ram, it is not doing the work required to create all the instructions needed to create the highest fps that it can create it if the CPU received more regulare deliveries of data.
Dual Channel memory has the potential to deliver twice as much memory data in a given period of time becase teh two channels can operate in tandem with each other and thus reduce idle time of the CPU, allowing it to send more data to the GPU to render the frames.

Yep
Wow, ty. I knew most of this, but I’ll screenshot it anyway
Thanx alot
!! Thx~
I added one more 8gb stick in my rig for dual channel and can definitely noticed the improvement in games and overall usage of pc, 100% worth it.
I knew all this but still enjoyed the video! Thanks.... And happy holidays!
I remember asking that question on your stream. Thanks for the more elaborated explanation.
Very good and informative video. Thanks Science Studio!
Very informative video as always.
Thank you sir.. new to pc and, this just helped me with my FPS all over the pace on insurgency sandstorm. Finally !
Im actually kinda surprised at those differences.
Ive built at least two systems this year for friends with only a single stick of 8GB, with the idea that they would upgrade to 16GB when prices finally go back down.
I always heard the difference was negligible, but now Im wondering...
I like the Paul's Hardware style setup my dude 🙏 desk, monitors, PCs, lighting look GOOD
Maybe a crash course on some of the most difficult parts of building a pc for beginners... like the tiny little plugs that go on those metal prong things on the motherboard...for the power reset etc.. I hear that those can really confuse new builders like myself and my one buddy his reset isn't even hooked up right because he wouldn't get those plugged in right lolol just an idea, great content and video Greg!Happy Holidays to you and you family :)
This was a really interesting topic. Great video.
how about the performance difference between 8x2 dual channel or 4x4 dual channel? having fully populated ram looks good though. is there any downside to that?
I found the same results in my tests...It does make a difference.
Cool, the reality is it doesn't though. Games don't hit memory bandwidth limits, Gamers Nexus did extensive testing on this.
@@marcleblanc3225 Yes it does! You will have will have 20more fps in dual channel mod vs single in games like total war, and assassins creed that are more cpu intensive with a gtx 1070 for example.
40fps vs 60fps is a big difference.
@@MoneyMaking861 this has been extensively tested by other people. I'm talking significantly more so than the testing done in this video. The differences between dual and single channel for gaming were found to be negligible at best. I suspect there's something else that's been overlooked in this video.
@@marcleblanc3225 Like this one? ruclips.net/video/kCg7eVN6N9w/видео.html
Do it on your pc You'll see..
Victor Ov It does make a huge difference you’re right. It’s been proven time and time again that single vs dual channel makes a huge difference
Fantastic video, good line-up of facts.
Great channel! I have a question, do I need the exact ram of the same brand to activate dual channel? Or I can use rams from different brands?
Perhaps the reason why other tests do not reveal big differences between single vs dual channel ram configuration is the number of CPU cores and CPU speed. Keeping the CPU threads fed with data requires RAM bandwidth and it should make a difference if you are testing with a 4core/8thread or a 8core/16thread CPU. I am not sure what CPU was used in Gregs testing. Since I saw a Z390 mobo, I assume a i9 9900k 8core/16thread CPU, which in fact is the CPU that would make the most out of dual channel configuration as of today. If other testers used lower end CPU can explain why their results do not show big differences.
He did show the specs, yes it was a i9 9900k . I'd also like to see the same test done with lower end, as you said the number/speed of cores would also play a factor in whether single vs dual would make a difference. For example I highly doubt a 2 core 6th gen i3 would need dual channel
Not really about CPU speed but rather GPU speed. Single vs dual channel won't show difference if you have GPU bottleneck. Pretty much all performance aspects considering system memory, channels, timings, clock speeds require elimination of GPU bottleneck if they are going to have impact on overall performance. The other test mentioned used lowly GTX1070, framerates were much lower what 8700k(cpu of test) can do.
Large number cores have no relevance, workload in games don't scale with number of cores. If it does(too few cores), then your cpu is badly congested and game is stuttery mess. Doesn't matter what kind of memory you have.
I swear your videos always come at just the right time, it's like you're reading my mind... o.O
Have seen most pre-builds with one 8 gb module in single channel. Almost all self-builds are dual channel. Great video, thanks and Merry Christmas Greg!
Your thumbnail should be a cover for a movie :P. Thanks for the amazing videos
Greetings from Saudi Arabia
Nice video, Greg! Steve from Hardware Unboxed made a comparison of RAM and saw that the game caches and give different results by each pass, did you see something similar? Maybe first allocation is worst with less channels, but reading after is not that sensitive to the bandwidth. In any case, I am just curious on the test methodology. Thanks for the video.
How does having 16 gb's via 2 dimms effect performance compared to 16 gb's via 4 dimms? How does the memory controller handle the extra sticks and how does that effect frequency and timings?
To my knowledge, there's little to no difference as long as the 2 dimms are in dual channel. I'm not sure on your question about frequency and timings but i would assume there would be no difference there either. Damn it, now you got me wondering. Haha
Pandy Owl I know that 4 dimm kits cost more than 2 dimm kits for the same timings and frequency, so I assume there's additional binning that occurs. One of the criticisms of Principled Technology was they used 4 dimms on which I guess exposes a weakness in Ryzen's memory controller? It was also common last year during the crypto craze to recommend people get 8 gb's and buy more when prices dropped.
It's common to think that four modules are bad, bicause you can't ad more ram (32gb). But actually for the most part 4x4gb is faster(enough to favor them against 32gb) and enough for gamers.
@@TheSilviu8x 4x4 has the same speed as 2x8 on Ryzen since it has a dual channel controller
@@truedarklander It's not that simple. Sure, in everyday use there's no difference. However, depending on the topology the maximum speed may suffer.
You should do quad channel vs dual channel next and see if 32 vs 64gb really is worth the cost adder, and if you do increase the amount of memory, should it be more gb per stick or more sticks? Is more really better? I really like my Samsung B die @3200MHz CAS14 (2x8gb) Team Force Group Dark Pro (single rank). A video on Samsung vs Micron vs Hynex would be enlightening, for many, as well. Keep up the good work. It is appreciated.

I found it funny how you poked fun at the Verge RAM set up and then the Cable Mod ad had the RAM set up incorrectly as well.
I think you oversimplified it a bit and missed out on an important point... The content in the Dual Channel DIMMs is not mirrored, so it's not just higher bandwidth. A better analogy is single channel behaving like a single HDD, while dual channel behaves like two HDDs in a Raid 0 configuration. In the highway example, it's more like single channel is one highway going east to NYC, and dual channel is another highway in parallel going east to Philadelphia. The numbers of lanes per highway is the same in both examples, so in theory there is more bandwidth, but a car on the Philadelphia highway will never be able to reach NYC.
I'm not sure how windows lays out the memory map, but it most likely alternates pages between the two channels, which if each thread is allocated its own page, then the benefit is pure bandwidth. As you said, it depends (what memory is being accessed, how many times, how frequently, etc.).
I did some research on this the other day, trying to understand the difference from an electrical perspective. It turns out that it's pretty simple: single channel vs dual channel is 1 memory controller vs 2 memory controllers, each with their own address, command, and data lines. So a CPU that supports dual channel will have a DQA and a DQB bus. In terms of DIMM slots, for multiple slots on a single channel, each DIMM has their own set of clocks and chip-select lines, but everything else is shared within the same channel. So A1 and A2 will have the same DQA lines, and AdrrA lines, but will have CLK0 + CLK1 and CLK2 + CLK3, respectively. Each DIMM has 2 clock lines and 2 chip-select lines, to handle single rank (1 sided) vs dual rank (2 sided), where each rank has its own chip select and clock. Additional chip selects are only helpful for capacity (since two chip selects effectively add 1 bit to the physical address space), because transactions (reads or writes) cannot be run in parallel on the same memory channel (hence the benefit of dual channel). Unfortunately, that means that when not doing burst transfers, the memory bus is mostly inactive waiting for the RAM to be ready with the value to read.
hjups as far as i know dual channel ram works exacly like raid 0.
@@mtunayucer I'm pretty sure it's a little more complicated than that, but it's a close enough analogy from an IT perspective. In reality, it depends on a lot of technical details of the implementation (bus topology, physical address mapping, software page mapping, etc.). Also keep in mind that hard drives don't map to address space like memory does, they're typically controlled by DMA engines, and some registers.
jeez you need to make your own youtube channel
Thanks for the info.. everything's not the same, everything is a bit more complicated if you take it as such.
It's more like a highway with double the lanes than two highways heading in opposite directions...
Ha, The Verge dude. My friend (who has built systems, but not in 7 or 8 yrs) and I built my first rig 2 days ago. He was mildly upset we didn't hit any real roadblocks. Biggest hurdles were enabling proper RAM speed, 3000mhz, and splitting the data from one mechanical drive onto an SSD and a second new mechanical drive, mainly cuz I'm kinda thick, and was tired by that point.
Hey, I have an option called unganged mode for my RAM on old Phenom motherboard. I've run the numbers and it does better than dual channel. I do have 4 x 4GB RAM stick and my CPU is Phenom II X4 965 BE (4x 3,4Ghz). How it works is it assigns one stick of ram to each CPU core.
Interesting stuff, I wouldn't have guessed the differences would have been that big.
On ryzen this makes a really big difference. In games you gain more by overclocking ram than overclocking the cpu.
Hi Greg if I run 2x4go ddr3 and 2x2go ddr3 (in the right slots for dual channel, and same clock speed) am I running 2 dual channels or does it disable dual channel function?
Is The Verge build going to make it into 2019? Seems that way 😹
My ROG Strix GL10CS comes with a Single rank ram kit. Can I upgrade it with a dual rank ram kit?
Hello i have a question:) im looking to upgrade my ram to 16gb instead of 8. I aldready have 2 sticks of 4gb ram in the 3 and 4 slot. But the problem is that the store stopped selling those. And i can only get my hands on an 1stick og 8gb ram. So that would make me have 1stick of 8gb plus 2x4gb sticks of ram. Would this work? And does IT matter if i place the 1stick 8gb into the 1st or 3d slot? Thank for the help.
Btw it is the same producer and the both are 2400mhz
What about 3D rendering? I personally have 2 2GB and 2 8GB to get 20GB, I need quite a lot of ram for some heavy renders. Is that still dual channel?
My mobo ram slots both right one b1and2 got fried some how or dont work after installing a new CPU in z270 Intel motherboard and I'm stuck with 16gb ram in single channel any advice?
Check for bent pins in the cpu socket. Had almost same problem on a z87 motherboard. Lost a2 and b2. Fixed the pins, and fixed the problem.
Years ago when playing WoW, I tested 1GB in dual channel and 1.5GB in single (3x512), although fps were worse in single channel, the reduced stuttering from HDD access was worth it for WoW. Warcraft 3 ran noticeably worse.
So, have you compared different workloads using Single Channel, vs dual channels, vs T - Topology? Maybe some video rendering, vs database workloads etc? I few like those would give a better picture.
"PULL A VERGE"
Could you try to do dual channel 2133 GHz vs. one channel fast stick (double if possible)?

I'm running dual channel 2x8gb ddr4 3000 in a msi b450 pro carbon ac. It also had that pop up in the bios when I had the sticks installed in the wrong slots.
Wait a minute, you recommend A1/B1 for dual channel but later in the video the bios recommend A2/B2. Time to re-test! ;)
though that when i saw the ram at the start, most mobos have it at the second and fourth slot.
Usually the recommended slots for optimal dual channel is as you've said A2/B2. That's what is recommended on my motherboard as well (Asus Z170 Pro Gaming), unless you're running 4 sticks in which case it doesn't matter where you put them since you'll have maxed out.
Edit: It's possible the difference between slot A1/B1 and A2/B2 is negligible of course, but as you said for the most part (every single motherboard I have owned) the manual recommends you use A2/B2 for dual channel configuration with 2 sticks.
@@musguelha14 then you could say the same about using the first pci e slot for the graphics card.
@@musguelha14 That would make sense, I've never seen an actual explanation for why the manual of motherboards recommends the specific A2/B2 dual channel configuration, but it would make sense if it's simply for clearance in the case the CPU cooler would be too large otherwise.
It's not just about clearance if the motherboard is using a daisy chain memory topology (which is common). Buildzoid explains it here: ruclips.net/video/3vQwGGbW1AE/видео.html
Thank you for the Premiere pro benchmarks!
I’m planning to build a PC next year and debating if I should get 3200 or 3600 DRAM at 64 GB (4x16), or 32 GB (2x16 or 4x8). I’ll be using it for gaming, Photoshop and video editing with Adobe Premiere Pro. For the CPU, it’ll either be a 9900K or the Ryzen 3850 with a 2080 Ti. Any suggestions on the DRAM speed and quantity/RAM kits?
Good bench. What is your view on using say, 3 dimm slots, for 24 gb ram, vs 16 dual gb of ram? More ram, but not dual channel, or less ram, dual channel?
My Lenovo 330s has a 4gb soldered ram already in place and an open slot for some more, should I get another 4 gig stick or spend the money for a 16 gig stick?
Wow, I knew it’d make a little bit of a difference, but I didn’t think it was anywhere near that amount!
I have been running 1x16gb for a couple years and didn’t think upgrading to dual channel would be worth it since ram went up in price so much (that one 16gb stick was $60 when I bought it) and have only ran low on free memory a couple of times before, now I’m reconsidering...
Debloat your windows, probably
Was watching the verge's roast. Wanted to learn more about dual channel. Came here and we have the verge here.
Can you show difference/benefits/draw backs for Dual channel vs Quad Channel on a Intel x299 motherboard or AMD Threadripper 2?
Nice video.
My mobo Asus 370 has 4 ram slot. Can I install 3 ram stick. Or 2 ?? Which one is better.
Not gonna lie. For a few months after my first build I did exactly what the verge did.
Noticed the single channel status in CPUz and fixed it quickly.
Its funny that you called out verge but has a footage for your sponsor showing you are doing the same as well, nice pun!
Merry Christmas dude.
you should have added quad channel to that last chart. my friend is considering having me build her a pc for photo editing. i wanted to go itx, so she can take it places. but i am curious how much faster a quad channel setup would be vs a dual channel.
I followed the Verge guide while building my PC and let's just say, I've been royaly screwing myself. But at least I didn't sort circuit my power supply because I wisely used the included vibration pads.
will it make a difference even on budget rigs like the one i have, ryzen 3 1200, rx 570, i have one stick of 8gb@ 3000mhz, will a 4*4 give more fps and smoothness in game? thank you for the video
Great video! Very informative.
I just wanted to mention that if you flash a caption on screen, please make it more than 1 or 2 frames. It was a bitch to time the pause to read it lol
By the way, do ram bottlenecks only happen when the CPU is bottlenecked at lower resolutions? Does this mean this is less significant at like 4K?
hey can I get both single channel and dual channel in the same rig? or is it counter productive and defeats the purpose?
Greg turns they verge into a meme
1:27 you should have took a screenshot from verge pc buid of the single channel set up from their excellent how to guide in making a pc to show what single channel looks like
You deserve more subs man
Can u test on a ryzen system as well and see if similar results. I bought a prebuilt last year when pricing was ridiculous. It came with 1 16gb dimm at 2400. I would like to see difference going dual and higher frequency. I have a 1600 doing both gaming and CPU intensive tasks
So I pretty much upgraded my entire everything on my PC right now but I'm skimping a bit on RAM since I'm running low on funds.
Question: If I buy a single stick 8gb ram now then buy another one later, will it run as good as a straight up dual channel 16gb?
I kind of did the same but had a single 16gb 2666mhz and 8700k when i got Another 16gb I got 30-40 more fps in BFV and much higher usage on the gfxcard. And all of the stutter was gone.
"pulling a verge" lol!
Another good video, thanks.
while on the subject of the Verge and other things they got wrong during the build...... could you see what difference it actually makes these days by putting the graphics card in the 8x slot please?
I know it never used to make that much of a difference as 8x was enough back in the day but what about today's 1080ti, 2070, 2080ti. I'm curious to see.
P.S. when I was 16 (1997) I was on a skiing trip to the Alps. The instructor was a hot blonde called Sophee, the way she said Parallel was way hotter than yours. Sorry to disappoint
That last comment made my day! Haha
I second this idea. For Science.
I don't have any benchmarks, but I was running a 1060 in a gen 2 x8 slot and it seemed fine.
@@caligoclarus it may seem to you that it was running fine but that was only a 1060.
I've found a techpowerup post from the 12th December 2016 that shows there is a very very slight decrease in performance using 8x gen 2.0 and lower but that was only with a 1080.
I wonder if the performance difference is even wider with a 2080ti
To run dual channel with 2 memory sticks, I should put one in the A1 slot and the other in the B1 slot right? At least for most of the motherboards?
Im here running memory diagnostic... and i look over to my pc window and see both ram sticks right next to eachother 😅
Hi Greg, have you checked your timings for both configs? Maybe they changed and caused the big difference in the results. I know from personal experience that bad timings have a huge impact on performance.
I'm suspecting there's more than just dual channel vs single channel differences in this. It's been extensively tested by multiple people with very minimal gains in gaming applications.
Exactly the video i wanted thank you ! one of my 2x8g kit died last month and i had this feeling my games used to run faster.
I guess it's time to order a new 2x8GB kit.
Wait, that is an intersection of Semanggi, in Jakarta, Indonesia. LOL. Good example as our cities has a TONS of bottleneck in road :P
Right now I using 8GB ram kingston hyperxfury, I just ordered another 8GB ram to make it dual channel!! I can't wait!!!
00:45 did you pull a verge putting both rams in the two left slots?
how would your system have fared with only one dimm instead of 2 in single channel? makes me curious whether the huge loss in performance may have been due to suboptimal memory management and thus standing in its own way in the single channel
also i'd be interested what difference single rank vs dual rank dimms would have made in that test

Greg, could you test in older CPUs? I think this difference in dual channel seems to be more prominent in newer CPUs. I have a i5 6600, wonder if in something like this we would see a difference.
So… i have a 7700K & a Z270 board. If i wanna fill up my RAM slots, do i buy two separate dual channel kits or can i just buy a quad channel kit?
I'd be interested to see how OBS Studio reacts to single and dual channel memory.
How do you know which slots are optimized for dual channel? Currently I have only 1 stick of ram and it is in slot A2 when my second stick arrives ill put it in slot B2. Or should they be in slots A1 and B1? My motherboard is Asrock z370 pro 4. Can somebody help me with this one?
have a Merry Christmas Greg - I'm still feeling the AMD-build urge. Do you think a 1950x would be great for a homelab server? I notice they're down to $500 new now...
@ScienceStudio, some motherboard do not have B2/A2/B1/A1 lineup, my motherboard has it set as B2/B1/A2/A1. Before you just carelessly state "oh don't do it like what he did" you should verify whether or not some motherboards hold up that way. Even I thought was for dual channel you'd have to do one spacing apart, but it turns out some motherboards have it adjacent.
Still wondering if there will be some benefit to go with 2x16gb or 4x8gb on quad channel or it would be the same.
Friend of mine built a pc with an i7 7700k and managed to build both ram-sticks into channel a. in bf v he didn't even get 50% of the frames he has now after building it right. it does make a huge difference ^^
Grab has always been memory bandwidth hungry. Going from a 3770K -> R5 1600 wasn't a upgrade for gaming, but that DDR4 memory gave me like 15% more performance
im using asus h370, a2/b2 slot as well or a1/b1?
