The target market for those chips buys almost exclusively from large OEM system builders, so that's where all the supply went.
Yeah it makes sense. Rarely do people custom build their own office machines. But they are great chips for low power with ECC. That's a rare thing to find when doing a custom build.
I've been trying to get one for a high efficiency build, but the sparse availability and relatively high cost (compared to non GE equivalent) is keeping me from buying one
I find the 4750G and 4650G come up on eBay often for decent prices. Not too different from the 5000 series PRO chips. I think slightly different cache amounts and of course just a bit slower performance (Zen2 vs Zen3). Still very efficient.
The only thing I'm not sure about is their max RAM amount. I know the 5X50G series supports 128GB (depending on mb), but can't find any info on the 4X50G series. I assume also 128GB like the non-PRO variants.
I got my 5650G on EBay for ~ $170 USD and the 5750G was previously > $300 but I noticed a few sellers at the $200 mark lately.
I put this into my server, its running 64gb of ECC memory and handles my transcoding and Jellyfin very well. Multiple 4K Transcodes and HDR support out of the box, while consuming as little as 10w to do so. Its the perfect media server platform as it checked off all the boxes.
My server needs an overhaul (Ivy Bridge Xeon + 8GB ram). I've been thinking of using Zen 3 too, since Zen 4 is too expensive. What motherboard and memory modules are you using? And did you verify that ECC corrections and errors are sent to the OS (more info: https://hardwarecanucks.com/cpu-motherboard/ecc-memory-amds-ryzen-deep-dive/5/)?
dmidecode -t 17
Memory Device
Array Handle: 0x0030
Error Information Handle: 0x003F
Total Width: 72 bits
Data Width: 64 bits
Size: 16 GB
According to dmidecode it is properly utilizing ECC, my non ECC systems only show 64 total and data width.
I totally went on a guess if this would work as there is not very much 'complete' information on this build. As mentioned in the link you posted its very hit or miss. Since I have ZFS running on here, one of its soft requirements are ECC so I wanted to ensure I had it fully implemented or not.
I am using my old desktop platform on an Asus Prime Pro x470 with this memory. Its clocked at 2666MHz with some fairly loose timings (no XMP/DOCP, I kept timing stock). I was able to easily get it to 3200MHz with a slight voltage increase for some slight gains.
The G CPU's are not all dreams, I had to update my stable Debian's kernel to a backport and to use tools like radeontop or nvtop I had to compile them in manually as the distro ones are too old to read the Renoir based GPU. Outside of that, everything works great for Jellyfin running behind linuxservers docker container. I used the linuxserver/mods:jellyfin-amd docker mod on their jellyfin container and it worked right away. H264/H265 and HDR support all out of the box.
Its a great chip, I am very happy with my purchase. 4.2GHz all core with boost around 4.6GHz.
Thanks for the reply! It does seem like, from my research, that the Asus boards (specifically Prime, but probably all of them) support ECC completely. But as you said, this information is not centralized anywhere. Just random forum posts like this.
