Good timing as Wendell just posted about EPYC on AM5. As i just completed my new EPYC server today. Replaced my Ryzen 5600x based AM4 server I just had in the same chassis. So far it seems to be working great with proxmox.
Running it on an AsRock Rack B650D4U with a AMD EPYC 4244P,
Dual 2.5G NIC, and the Gigabyte low profile 4060 for passthrough to a VM. Have 64GB of corsair DDR5 memory @5200 that works out of the box.
So far its all working with no issues and restoring my gaming VM and passing the GPU back through was seamless. Now time to see how the stability holds over the next few months
I just watched @wendell’s video about EPYC on the AMD AM5 platform, and I have a few questions. First, why purchase EPYC on AM5? I would assume EPYC on the AM5 platform would have the same limitations as the RYZEN AM5 when it comes to PCI lanes, or am I wrong? Second, could someone explain Wendell’s video as if they weren’t talking to a Computer Science major? I usually get most of what Wendell tries to explain, but not this time.
If you are an employee managing servers, and propose AM5 with EPYC for cost saving niche use cases, it has higher chance of being accepted. In professional environment with desktop AM5, you are exposed to criticism if/when things go bad/down-time/reboot.
In a home environment, Desktop AM5 with udimm ECC is great value and very stable/reliable. Just check in great detail the motherboard comparability with ECC udimm, in practise by reviewer. (Wendell alludes to some Motherboards advertising “compatibility” but with “partial” functionality when RAM errors occur.)
If a board is marked as AM5 EPYC compliant, you don’t have to worry about that, and deep dive into desktop AM5 motherboard udimm ECC testing/reviews.
For my homelab I have Desktop AM5 with udimm and Siena EPYC with lots of Lanes and RDIMM, but the Desktop AM5 with ECC is really fantastic value and performance. Most people don’t know this but many Mellanox NICS and GPUs will run just fine performance on x8 and even x4 lanes. 2*48 = 96 GB ram is enough for many homelabs.
Hi, not sure about that, in detail.
In general I find there is a huge difference running a Proxmox with VMs ( that often hold cpu cores hostage from lower states.
When you run an LXc/CT exclusive Proxmox host it does idle down very efficiently.
If you really want energy efficiency start by using
To identify if you can accomplish same services on LXC/CT or Host exclusively.
