So in this video (AM5 mini-server: N1 Jonsbo and... may include a bandsaw - YouTube) Wendell says that ECC RAM worked on this board but then stopped after a BIOS update. Does anyone know if it has been fixed or which BIOS version worked?
This is kind of the perfect mini ITX board for a NAS, and it seems to be the least expensive B650 mITX board. Is buying this board and rolling back the BIOS a bad idea? I am planning to build a NAS.
I wondering the same thing, hope he pops in and updates us
I’d also love an update about this. Currently trying to decide which platform to go with for an ITX NAS / Jellyfin server.
still not working, works on the PG ITX from asrock though.
Does the GPU slot support PCIe 4 x4 bifurcation? I am looking for a SFF build to demo AI accelerators that we are building. The idea is to plug in an expansion card like ASUS Hyper M.2 x16 in GPU slot and then plug in 4 accelerators, each taking up a x4 lane (even PCIe 3.0 is fine)
Bifurcation may also be relevant for NAS builds with some insane M.2 RAID 0 madness.
The slot supports x16, x8/x8, x8/x4/x4, and x4/x4/x4/x4.
Hi,
Did anyone manage to get ECC running on this motherboard?
I see that there are a couple of new BIOS updates since then.
(F9c seems to be the latest one - 16th Aug 2023)
I would be interested in buying one but I could not fine any info beside what Wendell said in the video. @wendell did you have the chance to give it another try?
Thanks!
F9 and F20 BIOS do not support ECC memory.
Does anyone have an eye on any similar boards that support ECC (other than the PG ITX since now it’s been a few months)?
ASUS ProArt B650 has ECC memory in the QVL. I don’t have any experience with the board, but it’s rare to see that stuff on a QVL.
I can confirm the X670E ProArt has ECC.
I suspect DaAwesomeP was asking about ITX boards specifically though.
Yeah I’m trying to build a small and low-ish power NAS so ITX is preferred, but I think now it will be more cost-efficient to look at mATX.
I really wanted the 3x M.2 but I guess I now need to to decide between ECC + 2x M.2 + ITX and ECC + 3x M.2 + larger. I was going to use 2x M.2 for future write cache and 1x M.2 for future 10GbE, but realistically now that I have used ZFS more I know that simply adding more memory for read cache is probably good enough for me and the “write cache” was a misunderstanding and doesn’t work the way I thought it did.
I’m maybe still looking at the ASRock B650E PG-ITX WiFi. The larger ASUS boards are cheaper (can then pay for larger case?) and have everything I want but are bigger and maybe draw more power. The ASUS ROG STRIX B650E-I GAMING WiFi is very similar to the PG-ITX but with Intel Ethernet but unfortunately costs much more.
I’m using a SAS HBA so number of SATA ports is not relevant to me beyond boot drives really.
A short comparison (at least for what is important to me):

Look on ebay for Gigabyte MB10-Datto 
(it’s not going to satisfy your needs I just think they are a funny product)
