HI
Please be aware that some, (maybe all) early Supermicro C422 motherboards will require a Bios and VRM update to work with Xeon W-22XX CPU’s.
From
X11SRM-VF | Motherboards | Products | Super Micro Computer, Inc.
Note: To support 165W W-2200 CPUs, BIOS 2.0 & VRM update by Supermicro are required.
I sent two unused X11SRA-F/C422 motherboards back to Supermicro Support Europe last year for this modification.
These were mid - 2019. Rev 1.02 boards.
Supermicro upgraded the VRM’s on these boards to allow operation at 165W for the W-22XX processors.
Supermicro do not offer cross-shipment. The boards I sent were returned in 2 weeks.
The hardware update was introduced in December 2019, any board received with a serial starting with XX20…. (XX can be NN VM etc.) will already have the updates.
While waiting for the W-22XX series to be become economically available, I fitted one unit with a Xeon W-2140b iMac Pro CPU & 128GB - 2133 PC4 memory this unit is running in the next office.
At idle with W10 on a Toshiba XG6 NVME drive, CX354A Pro Nic, P600 video card and no other disks, this unit uses 60-65W.
I hope this helps.
Take Care
