Glad to hear it.
Gives me a little bit of confidence that my board will post once I get the cooler and RAM.
I'm still running Proxmox 7.x on my existing server, but will spend a few weeks testing/"playing" with the new Epyc system and Proxmox VE 8 before switching my VMs, etc...
I was also thinking of building a small Proxmox / Ceph cluster (for learning / testing) using the Epyc system as the main node, and a couple of my old/spare Zen1 Ryzen AM4 systems, for 3 nodes in total..
( I did it a year a so ago - as a proof-of-concept - on Prxomox v7.0, used Mellanox 40 GbE NICs with DAC cables, and using the 3 old Zen1 Ryzen systems I have sitting unused. )
I can document that effort in another thread if anyone is interested...
I'm in the same boat in terms of wanting / needing more PCIE lanes, and have been considering building a Threadripper/Epyc system for a number of years because of that.
AM5 / X670E board layout rant:
That's what finally convinced me to build a Thread ripper 5000x/Epyc Milan system to replace my 3950x system.
I was always going for 24 cores, and filled many online shopping carts with components for potential builds but, luckily I waited. Once I saw the Epyc 9224 price, and DDR5 pricing seemed to reduce a bit, I decided now was a good time...
You have more skill and confidence than me! Happy to see you have it all working.
Air cooling is always the primary path for me; I generally try and stay as far away from water cooling as I possibly can...
If you don't mind me asking, what are your CPU temps and power consumption at idle and under full CPU load?
Do you have any concerns about VRM temperatures?
I've actually only ordered two 16 GB DIMMs so far (~$80 each), as I want to make sure the system works properly before I invest a lot more money.
(and I'm hoping that DDR5 ECC pricing will decrease as every day passes... ).
Working with all-new (to me) socket/CPU/RAM is scary...
All my other systems (with the exception of my mainAM5 workstation) are AM4 / DDR4, and I'd forgot how nice it was to have spare CPUs, motherboards, RAM and coolers sitting around for testing and troubleshooting...
