Please explain why putting my memory to 3800/100 mhz makes my cpu go to 100C, but 3600/133 does not.. 75C max.

I have a msi pro wifi mobo, with version 1.70 bios. The mobo is rev 1. I have Win 11, and an 11900kf. I have Trident Z RGB. Model f4-400C18Q-128GTZR memory. The cpu is NOT overclocked.

The higher the memory speed, the harder the memory controller on the CPU has to work. Although, this is a pretty huge difference, it's not usually this large a temp increase.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

If you are using auto voltages, the board could have raised it.

1.368 is as high as I saw it during full 100% load.
