Hello everyone! 
Can anyone please help me whitelist cpu in bios?

I want to use Intel Xeon E3-1275L v3. I have error CPU unsupported and power off.

Have attached full bios dump made via ch341a programmer on unsoldered chip (MX25L6473E).
Bios version 02.28 27/09/2019
AMI bios ver. 4

Thanks

Post screenshots of first (CPU) & third (Mainboard) tabs of CPU-Z with supported CPU.
Make a photo of the screen with "error CPU unsupported".

I see that my case is almost identical to this thread: https://www.bios-mods.com/forum/Thread-H...DM-i7-4770
Will your mod from there work for me, or do I need something else? The error message is exactly the same as the thread's author's (ERROR: Unsupported CPU installed.
PC will automatically power down in a few seconds.).

Could you please briefly describe what program you use to edit the necessary lines? Thank you very much!

Yes, I think so.
