I discovered this excellent motherboard for my upcoming NAS project: https://www.asrockrack.com/general/produ...ifications The processor I’m considering is the Ryzen 7 PRO 5750GE, which meets all my requirements for a NAS CPU—strong performance, minimal cooler needs, built-in GPU for transcoding, and full enterprise support like ECC RAM. I’m curious if it will work with this chip. The 5750GE isn’t explicitly listed in the CPU compatibility list, but its specifications confirm it supports Ryzen PRO 5000 series CPUs, and it covers all G CPU models with their GE and PRO GE versions. Except for the 5750GE itself, which is nearly identical to the 5700GE (except missing some extra features), the only GE option available locally is the 5750GE. My gut tells me it should be compatible, but I’m unsure if the board has a whitelist to verify the CPU before POST. Any advice would be appreciated!
In theory it should function but I'm unsure about the risks. It's unusual, yet ASRock usually includes the 5750GE in their CPU support. If you still need an ASRock rack board for any reason, this model is officially listed: https://www.asrockrack.com/general/produ...U-2L2T#CPU Personally I'd prefer a desktop board that supports ECC and the same CPU, possibly with a BIOS flashback.
I think the motherboard might be costly, especially with the 2 x 10gbps Intel X550-AT2 chip. Likely you'll save money by choosing a mATX setup with an 8-port HBA card and a 10Gbps fiber connection. For instance, my current model Gigabyte B550M Aorus Pro-P includes ECC memory for Pro processors, has two PCIe x16 slots (one 16GB and one 4GB), and supports 2.5Gbps Ethernet. You can find similar options around $85 with 16 SATA II ports on an Areca ARC-1260, which also works with JBOD or hardware RAID. There are also affordable refurbished fiber adapters available on eBay for about $40-$50.
I understand, I won’t choose those boards. I’d prefer something with ECC support, plus a 10G Ethernet card and extra SATA ports if required. That way I can meet all the needs here.
I appreciate the suggestions for alternative motherboards. Considering your NAS chassis, you're limited to the mini-ITX size. You're also planning to switch to SAS drives eventually, so having a PCI-E slot is wise. The board costs around 520 GBP, but it offers all the features you need. If you're unsure about the CPU, feel free to share your options—I'm happy to help compare them.
