I picked up some Gold 6268CLs and tested them on a HP DL380 G10, Dell R640 and a Supermicro X11DPU-G7-Ni22 with no success. The Dell and SuperMicro will not post. I tried 3 pairs on the HP with 3 different results; 1/no post, no fans, blinking front lights. 2/no post, fans on full speed. 3/I did get a display with a bunch of code being outputted.

CPUs were pulled from Oracle servers. I could've bought some 8273CLs as well but already have some 8270CLs at the same cost. 8270s work on any machine.

you might need a specific bios version. I forget the exact version.
Also if you want 8273CLs I have 4 of them available for sale.

see my post from last year about this, you need an old version of the BIOS in the DL Gen10 :

imho, it's not worth the hassle if the server is used in production, you're stuck with an old bios, HP warranty is gone and you must be 100% sure to never upgrade the bios, as it will immediatly brick the server. to downgrade again, you must swap the cpu with a supported one, then downgrade and reinstall your fancy "6268CL"
HP does not want its customers to use these CPUs , altough it works perfectly. I have 2 DL 380 gen10 in a lab running 24x7 on 6268CL with the old bios and they have been rock solid, not a crash or weird issue.

I did try 2.3.100 where I saw cascade lake support was added but it doesn't boot with it.

I then tried 2.14 and 2.2.9 then 2.3.x and none of them boot.

read the PDF RelNotes, there is info about microcode.
BIOS 2.14
Updated the Processor Microcode to version 0x3302 for the second-generation Intel Xeon Processor Scalable Family.
2.14 is much too new BIOS.

Only version 1.2.11 which is released on 10 Nov 2017 mentions update scalable processor microcode to version 0x2C


1.3.7
Update scalable processor microcode to 0x43

So if you are saying to me look for a microcode version 0x1C lower , I can't see one.

I don't think this will work as 2.2.9 was the first bios which has " updated processor microcode to version 0x21 for the second generation intel Xeon"

The other bios files before that do not mention anything else to do with the second generation.
