Motherboard: TUF GAMING B650M-PLUS
CPU: AMD Ryzen 9-7900 or 9-7950X or AMD EPYC 4464P or AMD EPYC 4564P
GPU: nVidia Titan V CEO and nVidia P600.
Memory: Kingston KSM48E40BD8KM-32HMKingston 32GB ECC DDR5
Rest of it im comfortable and no help needed.
Im scaling down my Asus Z10PE-D16 WS to TUF Gaming 650M-PLUS. I need MATX due to size on my desk. I do mostly light office work, virtualization and this is where i got stuck in choosing boards.
My plan is to run AMD Ryzen 9-7900 or 9-7950X ( later one due to 16c32t and difference only 100 Euros between ryzen serias and 100Euros between EPYC 4464P or AMD EPYC 4564P ) + 2 GPUs + 2 nvmes + 4 SSD`s
Why 2 GPU`s ? I have nVidia Quadro P600 to run my monitors and because i can run 2 extra monitors from CPU it makes 6 screens ( the more, the better for my needs ) and second GPU is nVidia Volta series which is used for virtualization in VM for LLM - so this one would go to PCE x16 main slot and P600 would go to x4 - but its running on chipset and i have 2 nvmes. Im lost in understanding what slots works and what does not when all nvme slots are filled. Support page shows M.2_1 5.0x4 and M.2_2 4.0x4 ← this one from chipset or cpu ? And will my P600 run 4 screens ( no gaming ) which is powered by PCIE only and fitted to pcie x16 x4 from chipset ?
Will VRM be enough to run my chosen CPU ? i will not OC it.
Memory: im Planing to use DDR5 ECC (Kingston KSM48E40BD8KM-32HMKingston - 1 stick 32GB) but again - im lost on ECC. Will it run on ECC mode ? if yes - can i use all 4 slots to have 128GB ECC or only 2 slots and 64GB in total?
Will be using FreeBSD as main OS and Linux inside bhyve for virtualizations.
I don’t think that performance will be stutter free using a P600 in a chipset-based pcie slot powering multiple monitors on hitting the storage with VM’s and LLM model using chipset-based nvme/sata ssd
Only EYPC and high end boards AM5 chipsets support multiple CPU-based PCIe x16 slots and give you the proper performance,(X670E and B650E boards that speicfically mention both x16 slots are cpu based). And it’s also up to the motherboard itself to whether it supports DDR5 ECC.
Example being, many gigabyte X670 board did not support DDR5 ECC UDIMMs at launch, only 2 years later during the launch of EPYC 4004 AM5 CPUs did many boards get DDR5 ECC UDIMM support but not all of them, and you still have to manually check if they got the BIOS update to support it.
I run a similar setup with size constraints and chose a Cooler Master Qube 500 Flatpak, it fits an ATX board and PSU while being the size of a MATX case. I fit a X670E-E Strix and two GPUs and a ATX PSU with little issue once you figure out how to build the case.
My chosen ASUS motherboard supports Epyc, supports ECC ( serial number was taken from CPU/Memory support list in manufacturers website)
P.s. What about 170W CPU ? Will be ok with manufacturers stated VRM`s? I will not overclock it.
12(60A)+2(60A)+2 Power Stages
12(60A)+2(60A)+2 power stages are rated to handle up to 60 amperes, combining high-side and low-side MOSFETS and drivers into a single package to deliver power, efficiency and stable performance for all compatible AMD processors.
Why im thinking about EPYC 4464P 170W cpu as it looks like its equivalent to Ryzen 9-9950X and today my Epyc cpu cost only 457 Euros from 751 Euro . Dropped almost 50% and 9-9950X - 700 Euros
EDIT: My bad, 170W EPYC is R9-7950X actually and no R9-9950X
That EPYC is Zen 4. And Zen 5 CPUs like the 9950X really do give up to 50% better performance depending on the model and workload but generally its not worth the upgrade
As for VRMs, Idont think it’ll be an issue but lower end b650s do sometimes throttle on higher tdp cpus. You can’t trust the marketing. The whole 12+2 power stage is really just a 6+1 power stage with dual phases. What this means is that they cheap out on the components, giving you lower efficiency VRMs that need heatsinks or they throttle.
It’s one of those things where a decade ago, big heatsinks on a board meant high end OC, but now its worthless.
I reccomend chosing a board based on Hardware Unboxed AM5 motherboard roundups, they do pretty good reviews and tell you which boards throttle.
Oh, im new to AMD CPU`s last time i used it was in year 2000. They had Athlons since then im Intel boy so im getting confused with Ryzen cpus … zen 4 / zen5 etc. am4 / am5 … But im really thankful for your explanation!
I was watching HU videos and this MB is one of ther reason i choose it but also i have to make sure i have enough stuff on MB to make scaling down possible ( 2gpus) and some nvmes and ssds plus i needed at least 2 video outputs from MB ( hdmi, DP )
P.s. so i can also with all my needs use pciex1 slot as well ?
I know i can get extra 4 ssd`s with x1 expansion card.
Zen is the cpu architecture family powering AMD Ryzen Desktop CPUs since 2017
When you hear Zen 1 - Zen 3, that refers to AM4 cpus that can run on AM4 motherboard that use the X370/X470 and B350/B550 chipsets
zen 4 - zen 5, it refers to AM5 CPUs that support AM5 motherboards that use the X870(E)/X670(E)/B650(E)/A620 chipsets
EPYC/Threadripper is rarely referred to by the zen generation but by the generation name such as how Zen 4 or Zen 5 based EPYC/Threadripper are called Genoa or Bergammo
Sorry, I don’t know of any MATX board that supports dual cpu based x16 slots.
Best I’ve seen is a single X16 slot with 2 nvme slots and a pcie x1 slot and some sata. MATX is really just meant for gamers these days who only need a single GPU and a wifi card
Yes, chipset - another ingredient in the mix plus all these 1 3 5 7 9 models, plus 3000 / 4000 / 5000 all the way to 9000 series - bit confusing. Took a while to get a small grasp on what they mean
There are few - but only few and also there is awesome X399 Asrock Taichi matx board with 3 pcie x16 mode 16 running as its for 2 gen threadripper … i was debating about it but decided it would be very small upgrade from dual my E5-2690 V4 Xeons - my heart wanted, but brain told NO
I agree that matx boards are for gamers and if for servers they are insane in pricing and still lacks dual x16 pcie slots but i whish there was something similar to X399M … we still have 24 or 28 pcie lanes ( as AMD put Epyc to AM5 platform ) and if there are Motherboards with 2 x16 slots and 2x1 slots on one matx mb and running different modes - manufacturers should start to take attention to it …as same cpus getting into atx boards and pcie lanes getting split for 2 gpus and matx board easily can take 2 dual slot gpus and nova days there are plenty of WB to make single slot gpu plus we pay huge money for matx boards too , obviously its not itx but still. plus /// home labs - mini pc`s … we try to cramp stuff into shoe boxes
