Dell 5820 CPU Compatibility
Hello, the motherboard that is in my 5820 says 002KVW on the sticker near the cpu. Will this board accept the w-22xx series cpu or only the w-21xx series? I am still on bios version 2.0.2 but there is a update available that I haven’t updated yet.

@Chino de Oro I’ve seen some of the lower end w-22xx going pretty cheap on eBay. I might just purchase one to test it out

the C422 chipset is strictly limited to work with workstation processors only

some more user report:
“There are a few revisions of the motherboard used in a 5820 ( same goes for the 7820 and 7920 ). The initial revision when the units were put on the market around 2017 works only with W-21xx.
The revision put out when they started to offer the option to sell it with a W-22xx ( I think during 2019 ? ) , supports both 21xx and 22xx”
“If you bought this 5820 in 2017 (you can check with the Service Tag here Product Support | Dell US ), it'll not work with 22xx cpus. It's not a bios issue, some components are slightly upgraded later on, to allow the use of W-22xx”
@DELL-Chris M do you have Dell confirmation of which 5820 boards are for W-21## only?(edited)

@redxps630 No, the parts page does not specify. It just list the motherboard part numbers.

0X30MX works for sure with the W-2295

Unfortunately Dell can not provide a definite word on cpu compatibility and we are left to user reports
user report
”according to several user experiences/statements discussed in the Dell Community threads [1, 2, 3, 4, 5] and mentioned on this websites [6, 7, 8] and clearly here, I am able to vaguely conclude the following MB/CPU compatibilities, which were mentioned …
… several times:
02KVM & 0X8DXD: W-21XX
06JWJY & 0X30MX: W-22XX
… only once:
0R23KR: W-21XX, W-22XX”

@uco73 according to Build-pts Performance - OpenBenchmarking.org seems it is compatible

@mcnaught82 , yes, the second generation of Xeon W processors are around 10% - 15% faster than the first generation of Xeon W processors. In addition, it can support faster memory as well.
Unfortunately, the board of 02KVM (mistyped as 02KVW) does not work with Xeon W-22xx processors last time I checked.
