Purpose: AM5 Linux Workstation for Proxmox VE and VFIO compatible. All parts are from one supplier and they will do the build.
BOM:
Processor | AMD Ryzen 9 7950X3D 16 Core Processor |
CPU Cooler | Deepcool Assassin IV CPU Air Cooler Black
Motherboard | ASUS PROART B650-CREATOR |
Queries: Hopefully the IOMMU groups are ok now. Please advise of any gotchas. The board does not have Wifi/BT, Please suggest a suitable card if possible.
Query:
Options 1 and 2 are the same price. Also would there be any issue with upgrading to DDR-5600. Not sure if the supplier knows of any constraints for not recommending Option 2. My questions are:
Would it be better downgrading to Option 3 for that 10% cost saving at the cost of lower performance.
Is it a must to buy one 4x32GB kits ?
Storage: Samsung 990 EVO 2TB M.2 Gen 4 NVMe PCIe [Supports PCIe 5.0x2 / PCIe 4.0x4 ].
Its double the price of standard PCIe 4.0 with Read Speed of 5000MB/s and write speed of 4200MB/s.
I initially did not consider PCIe 5.0 (this seems to be the only one with that supplier) but there are other options in similar price range such as
- T-FORCE A440 Lite, M.2-2280 Internal SSD, PCI-E, 2TB, Read 7400MB/s, Write 6400MB/s
- Kingston KC3000 PCIe 4.0 NVMe M.2 SSD 2048GB - Read 7000MB/s, 2048GB - Write 7000MB/s
These on paper seem to offer faster performance than Samsung. Please advise whats going on here.
One benchmark suggests Micron Crucial T500 2TB M.2 NVMe PCIe4 SSD is the faster drive than the Samsung 990 EVO 2TB M.2 Gen 4 NVMe PCIe as well.
Case | Cooler Master HAF500 ARGB E-ATX Case
PSU | FSP HYDRO G PRO 1000W 80+ Gold PCIe Gen 1
Any suggestions for better Cases and PSU aternatives or are these top tier? I am still doing my research.
CPU: The 7950X3D is probably a bit of a waste for this setup but if you want to throw money at it sure, go for fit.
CPU Cooler: Likely fine looking at be quiet! Dark Rock Elite Review - AMD Socket AM5 Results | TechPowerUp
Motherboard: Probably fine, Realtek NICs though…
Memory: Get something that follows JEDEC specs, some of the Fury series do otherwise https://www.idealo.de/preisvergleich/OffersOfProduct/203263217_-pro-64gb-kit-ddr5-5600-cl46-cp2k32g56c46u5-crucial.html
Case: Probably fine, I prefer the Fractal Design R-series though…
Storage: Get Crucial or Solidgm, P5 Plus (EOL), T500, P44 Pro are “decent” drives in general
PSU: Likely fine but way overkill, a decent 750W will do more than fine unless you plan to do something very excessive
Look to go with 2x 48GB RAM at higher speeds (up to DDR5-6400). DDR5-6000, I think, is considered the sweet spot on AM5.
Upgrade to workstation class 4 channel or higher platform.
In case of 1. consider saving on RAM by going with slower speed RAM sticks (e.g. 4x DDR5-4800), although I don’t think I have seen any reports on success with 4 sticks as most people want to take advantage of higher bandwidth here. Should be fine, though, because these are JEDEC certified speeds.
You don’t really want to go about of spec if you want something stable which seems to be the main goal here. Most of not all reports failure reports are using non JEDEC and/or manufacturer that focues on not meeting industry standards and going or out of spec specifications (overvoltage, SPD values being weird/broken/not targeting JEDEC speeds etc).
