Do i leave everything above as default?

I understand that if you increase the "PCI Express burn in mode percentage" to say 101.32Mhz, it actually translate to a minor OC for your gfx? Please correct me if i'm wrong. Is it advisable to do that ?

Btw, in my CPU-Z, i noticed that my multiplier keeps changing from 9 to 6 and then 6 to 9 every 5 seconds or so. This resulted in my core speed to change from 2400 to 1596 and so forth. Any idea why is this happening? Is it a bug or just my settings? A right click on my comp and system shows that i'm running at 2.4Ghz though.
if you change the pci-e frequency ever so slightly to lets say 101 or 102, you'll be perfectly fine. i dont think you'll see a performance increase due to the slight pci-e frequency increase.

as for the 6 to 9 issue... this is a bug with the bios. C1E cannot be disabled in the bios even if you set it on disable. so when you are in windows and you are idling (no load on cpu) your cpu will be running with the 6x mult. when you put a load on the cpu your cpu will be running with the 9x mult. if you could get C1E disabled, then your cpu would be constantly at 9x.

this has been an issue that many users have been trying to get cleared up with intel but intel CS has been kind of dumb and is blaming the CPU for the problem (at least from what i remember reading in this thread).
