Hi, i changed my processor from that i5 2500k to an i7 2600k and i'm getting very random whea_uncorrectable_error bsod.
Sometimes i don't get it for 24h and sometimes i get 2 or 3 times a day.
Maybe it has something to do with the bios that i wrote it in the past?

@alekskz - I can update CPU microcode for you if you want? This error has nothing to do with BIOS mod, but with your settings, the CPU itself, or possibly microcode update may help if not already latest.
This is due to unstable CPU in general, so settings, or possibly CPU you purchased is wearing out now etc. Both of your CPU's mentioned use same microcode, 206A7, and I checked, the one in BIOS is from 2018, so it could be updated (latest is 2/17/2019 version).
But, since you're having issues now and not with the 2500K, probably you need to adjust settings for memory, Vtt, vcore etc. until you are 100% tested stable.
This is especially true if you are using all Auto and large amount of memory (set memory voltages and add Vtt voltage), vcore may need increased as well if this is used/worn out CPU. May also be due to heat, if happens a lot under stress.

Here is "Fix.bin" BIOS I sent you previously, now with updated microcode for 206A7 CPU, this may help, but you still probably need to adjust/test/adjust until you are 100% tested stable

Stress or not does not matter, all I mentioned above applies. BSOD?? WHEA error should not cause BSOD, unless it's really bad, some driver possibly, or something is really not stable.

You should be able to flash the BIOS above renamed to stock BIOS name.extension (Sorry I forgot) then flash it with Instant Flash.
If not, let me know and I will remove the security check in it, then you can try again. Or just program in if you want, up to you

I am updating as we speak, i ll come back with an response if this fixed it or not.
Thanks
Microcode changed from 206A7/2D in bios to 206A7/2F

Well, looks like this bios update did something and now it s working as it should, running stable 4.5ghz at 1.355v
