Maximus VI Hero BCLK automatically boosting when stressing - pls help me stop it.

Hi,

This is my first post.

When I stress test my Haswell CPU, the monitoring tools (HWiNFO64, OCCT, AIDA64) show that the BLCK goes up to 102MHz (from 100.0MHz which is manually set in BIOS).

*check attachment

that is almost 1x multiplier bump. because of that, i cannot use a lower Vcore - I think. (well, i cannot check if that theory is true or not because the darn BCLK won't stick to 100MHz)

I need to stop this. Any help?

By using SB PLL, I think I have made it happen less often. By using LC PLL, which should also be same as AUTO at 100MHz BCLK, the monitoring apps show the BCLK bump way sooner.

I'm running a 4770K @4.3GHz at the moment. The bios is official 711.

Did you use any pre-configurated OC-setting in the bios?

Did you overclock yourself?

Can you check the BCLK in CPU-Z?

i overclocked by myself. i didn't use any pre-configured settings. they are not stable anyways. my CPU is a dog.

well, it doesn't happen very often. you cannot catch it in CPU-Z. you can see it only in apps that keep a record of the max value.
