processor swapping problem

ianGutierrezXeon — Tue, 03 Feb 2026 16:58:00 GMT

I have a problem. I changed the processor in my PC, from a Xeon E5-2420 to a Xeon E5-2470 v2, but when I turn it on, I get a WHEA_UNCORRECTABLE_ERROR (0x124) and it shuts down. It only works with one RAM module installed. I have a 400W power supply and an RX 570 8GB graphics card. Can anyone give me a solution? My motherboard socket is LGA 1356.

Does your bios actually the newer processor?

Your power supply may not be adequate.

Thanks, I've already tried my BIOS but it doesn't have any updates. I suppose it's the power supply; I'll change it for another one to see if that works. I appreciate your help.

Al's response had a typo and the thrust of his first question was lost. He was asking if you had verified that the BIOS is actually documented as having support for this processor. You should check the BIOS documentation to verify this.
Hope this helps,

Oh, thank you. Yes, I already checked and my BIOS is compatible with the processor, although I'm not that good with computers, but thank you.
