I had installed the new BIOS with the new micro code (125) for the Z790 GAMING PLUS WIFI with the i7-14700k on board.
After a couple of days I reverted back to the previous BIOS version “7E06vH52(Beta version)”, because even with the same BIOS settings, the CPU temperatures had increased about 10° under heavy load.
In my case, I think it is better to wait for the “final fix” from Intel before upgrading to a new BIOS.
I solved the temperature problem I had with the BIOS with the latest micro code(125).
I installed the new BIOS again and configured it with the same settings I was using with the old beta BIOS.
I ran a test with Cinebench R23 and the CPU was in thermal throttling after a few minutes.
So I encountered the same problem which made me go back to the previous Beta BIOS (h52).
But this time I didn't want to go back to the old Beta BIOS, so I rebooted the PC, entered in the BIOS and loaded the default optimized settings.
After that I reconfigured the BIOS from scratch including the fans curve, so set the same settings I had previously:
-Intel Standard Profile
-Enhanced Turbo = Disabled
-PL1-PL2= 175w
-CPU Lite Load = Mode 7
-IA CEP Support = Disabled
-IA CEP Support for 14th =Disabled
All other settings set automatically by BIOS.
I rebooted the PC and ran another test with cinebench r23, this time I had no issues even with new BIOS (125).
Now the temperatures are fine.
Basically, the difference from the previous time I installed the new BIOS (125), is this time I reset the BIOS with the default optimized settings and then reconfigured it.
A simple thing to do, but it made a big difference.
