BUS Speed

[MKBL]

On running OCCT, the BUS reading is 99.8 / original 100 all the time, even when the actual test is ongoing. Does it mean that something should be done on BIOS? CPU-z has the same reading.

I'd maybe update the BIOS are your motherboard? have you adjusted your changed your multiplier at all?

 

[MKBL]

BIOS is the latest, and multiplier is on default, since it is H67 board.

MSI customer service instructed me to disable spread spectrum in BIOS. and this solved the problem. I don't remember tinkering this option, moreover, I didn't know what spread spectrum was. Maybe it's a default setting?
