Hi,

I have just built a new PC based on a M13H, an intel 11900K and a Nvidia RTX 3090 FE GC. It is mainly used for Microsoft Flight simulator 2020. The result is really amazing, i.e about 40 FPS in the Ultra mode (1440x3440) and in very dense area (photogravimetry) at low altitude.

My Bios setting are those by default + Intel ABT on + resize bar on. When idling, the Vcore voltage permanently oscillates between 0.7 V and 1.45V, even when idle. This last value sounds too high in my ears.

My previous PC was a M9C + i7-7700K. As a result I am not yet familiar with the options of the M13H Bios. My question is the following:

1. If I want to use very conservative values corresponding strictly to intel specs, which Bios options should I change
2. How to limit the Vcore voltage in order to be sure to be in the official and healthy range.

By the way, I was obliged to turn off HT otherwise I get many BSOD's (clock.watchdog.timeout), even when idling. Switching off HT makes the system rock solid for several days now (no more BSOD).

When making an Aida64 stress test (CPU+FPU) with defaut preferences, i.e. AVX 512 ON, there are several thermal throtteling events. Is this normal ? I use a Noctua NH-D15S cooler

Best regards

Hello sl9,

I suggest to reinsert the thermal paste on the processor.
The range of voltage is normal paramters, because when it reach 5.2Ghz, it is usually 1.42V.

Thank you for the idea. In the Bios, i can read A prediction of SP=82 and a cooling performance index ranging between 166 abnd 176. Are these values compatible with the idea that the cooler is not correctly mounted with respect to the thermal considerations, i.e. not enought thermal paste. I have applied a round dot of about 3 mm on the center of the CPU as advised by Noctua.

Best regards
