BUS Speed

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.

More about speed
  1. I'd maybe update the BIOS are your motherboard? have you adjusted your changed your multiplier at all?
  2. BIOS is the latest, and multiplier is on default, since it is H67 board.
  3. 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?
