I received my H11SSL-i + EPYC 7551P + 256GB 2133MHz combo a few days ago. Ordered from
tugm4470 and provided the code "gb09s" from
the post on the first page of this thread, from user
gb00s.
First a few words on the seller. I don't think I've ever had a better ebay experience than this. Extremely fast communication and shipping. Received the package after what, 5 days?!
Unfortunately, one of the memory DIMMs were dead on arrival. After contacting him about it, he originally wanted the dead memory stick in return so he could get a refund from his supplier. I fully understand why he'd want that. Doing some research on shipping costs with tracking from Norway to China it became clear to me that it would probably cost more than the DIMM itself (from ~30 USD up to 140 USD depending on provider). He agreed that it would be pointless to ship the damaged/dead memory stick to check if it could be repaired, and offered to just ship me a brand new stick.
Did I mention that this has been my best eBay experience?!
On to the setup -
I've been building my own computers for almost 30 years, mostly on consumer grade hardware. Let me tell you, this is something else.
Popped in a 1660 Ti, and could not get it to post video. After some searching, BIOS/UEFI is posting through the VGA. Quick trip to the store to buy a VGA -> HDMI adapter had me served with video at least. Can confirm that Luxorparts VGA to HDMI adapter works. To use a PCIe GPU, you need to go into BIOS and set VGA to "offboard" and move the VGA jumper to 2-3. Just moving the jumper won't work.
In the boot menu in the BIOS, I kept everything default, with DUAL EFI/Legacy boot. I guess that was my first mistake. Proxmox installed with grub bootloader I think, and when I issued a reboot command in Proxmox, it would just hang during shutdown, or hang during post.
After disabling legacy boot, changing from NVMe firmware source to AMI instead of vendor, changing M.2 4x slot to EFI rom, and installing Proxmox again, it now uses the correct bootloader (systemd-boot, I'm on ZFS file system on the host storage).
To round it all out, a pleasant experience with the seller, and after getting through some hoops I have my server up and running!
