12th Gen affected by issues?

[dave343]

I have a 12400f cpu in an Asus Rog Z690-E board and Ram (g.skill) was at XMP 6400mhz CL32 for the last 1.5 years, no issues—original BIOS though. Yesterday I updated the bios to the latest and now the thing refuses to boot with XMP enabled.

The PC hasn’t had any crashes that I can recall, however it only ever sees Roblox and YouTube.

Nope, 12th gen is unaffected. It's only the 13th and 14th generations.

Maybe the CPU's IMC voltage (whatever the naming is in BIOS...) defaults lower now and you need to raise it slightly.

Thanks, I’ll give that a shot

I believe it might be called CPU VDD2, IMC Voltage or Memory Controller voltage but can vary. There is also VDDQ which supplies voltage to the output buffers of your RAM. No idea what to try changing it too, but upping them from whatever they're currently at might help. If it's on auto and you don't know, hwinfo can read them in Windows.

I'm rusty on modern Intel so good luck!

12th gen is unaffected by the issues 13th and 14th gen are facing. You can always roll your BIOS version back by one. However, the Intel ME will not roll back, it remains updated. FYI

They're even coming out with some new 1700 CPUs

I would revert the bios. Never update your bios unless you are having issues. But there has nothing been wrong with intel processors other than motherboard manufacturers set up the wrong electrical parameters to them.
