first of all, I would like to thank everbody who posted in this forum, it helped me a lot in my build.
I am happy to report that following components are fully compatible and working great
- Gigabyte MC12 LE0 (with F18 bios)
- 2x 16gb Kingston - KSM26ED8/16HD - Server Premier (non registered ECC)
- Cooler Master G Gold 550 V2
- NOCTUA NH-L9a-AM4
- AMD ryzen 5 pro 4650g
- IBM X540-T2 Dual-Port 10Gb in x4 PCI slot
- ASUS HYPER M.2 x16 Gen 4 for 4xNVMe (noisy little bugger!)
- 4 x SSD disk Kingston FURY Renegade NVMe 4TB
- 4x some old seagate drives SATA
- UNRAID running from USB stick
couple of comments
- it takes quite a long to start the systems (minutes) without seeing any signals of life... I was affraid that RAM, CPU or MB is faulty
- BIOS upgrade is not easiest - wolfgang's great blog really helped
Wolfgang's Blog
- at the end it costed much more than i expected and i'm willing to admit, even when sourcing from ebay.de
- ASUS HYPER M.2 is really noisy for living room enviroment, it's possible to turn off fan, i will give it a try and see how temperatures develop
- ASUS HYPER M.2 is also very long card, i'm still waiting for my sagitttarius 8 bay nas and crossing fingers it will fit
a question
my CPU is RENOIR with GPU and not supporting 4x4x4x4 only 8x4x4 bifurcation. Because of that, only 3 NVMe's are visible to the system in ASUS HYPER M.2
I am considering to switch to something like Ryzen 5 5600X to get full 4x4x4x4. I would still like to keep ECC support. And as there are no more free PCI slots (one slot is used by NIC and one by NVMe adapter) work without dedicated GPU (server will be accessed over BMC or http)
Or should I just keep configuration as is, have 2+1 NVMe's in unraid array, and 4th NVMe as a cache for SATA HDD array? (with a price and capacity of NVMe it seems quite an overkill and waste for me)
Last option would be to get another MB+CPU combo with more PCIe slots and integrated 10GBe NIC, but I would like to utilise existing investment as much as possible
thanks again
