I recently deployed a AMD 7900 in a Asrock Rack B650D4U motherboard, in my local colocation. I enabled eco mode in the BIOS to try keep power down as well. Fully updated the BIOS and BMC firmware.
Should a default installation Proxmox be ok with Zen 4, I’ve heard Wendell speak of updating the kernel on some Zen4 videos, and wondered if that still the case in the latest proxmox? Current kernel is Linux 6.8.8-4-pve as the time of writing. I’ve not had any stability issues, so maybe its ok now?
I also noticed my C states won’t go below C3, but I do have 2x Samsung U.2 PM9A3 installed, which could be limiting the C states, but I didn’t think those drives would limit it that much. Their the only extra PCI-E devices connected, I’m using the on-board IO for everything else.
Not sure If I should be applying any extra configuration. If anyone has any tips or anything let me know.
You probably want amd-pstate as your scaling driver. Also, by default proxmox defaults to the “performance” cpu governor so it doesn’t idle at all - changing to “ondemand” should help, even without amd-pstate.
Comparing with “watch -n 1 grep MHz /proc/cpuinfo” between those two governors should give you an idea of how they differ in behavior.
If I can ask one more question about the board, I would like to use Crucial 64GB (2 x 32GB) 288-Pin PC RAM DDR5 4800 (PC5 38400) Desktop Memory Model CT2K32G48C40U5 instead of ECC memory to save a some money, I can upgrade later. Manual says non-ECC will work. Are you running ECC on your server. This is my first real server build. I have mostly run old desktops and Raspberry Pi’s.
I use non-ecc memory in mine. I got 192GB (4 x 48GB 5800Mhz) CP2K48G56C46U5 to be exact. Although their running at 3600, because populating more than 2 DIMMs will cause memory speed to drop.
Of course you can upgrade to ECC later. If Eypc 4004 series supports non-ecc then of course. But I can’t remember if you have to go ECc with Eypc 4004 series. I use a Ryzen 7900 (non X) which will do both. Personally didn’t go for ECC as it doubled the memory price, of which the built was already getting quite expensive.
System has been rock solid ever since I install proxmox, not even one crash. Currently been in 24/7 production for 4 months, at my local colocation.
I’ve had no end of issues with my Minisforum MS-A1, which I can’t workout what the issue is, as I can’t reproduce it easily. The Asrock Board has been solid the whole time, so it’ll be a great choice.
I also use U.2 drives via M.2 adapters. You can find used but barely used enterprise U.2 drives on eBay for a good price, if you want that sort of thing. I brought mine with 3PB written but the durability of the drive is like 16PB, it’ll take some doing for me to wear the drive out . Reporting 92% health, so bags of wear left.
I’ve not done much for power draw, I think buying the 7800 or 9800 would be a better idea as having dual CCD draws more power. Not sure on the difference through
