I always start to test LinX in diagnostic mode because it does less damage if it freeze at Windows start and after multiple BSOD and itÂ´s also less services that can interupt.
My goal is to have less then +-0,15 in fluctuation between the runs, if itÂ´s more, itÂ´s usually to low vcore or not the right Clock skew, for example, if I use auto clock skew at Bclk 200 the fluctuations is more but if I set the clock skew at delay 100ps for CPU clock skew and normal for PCH clock skew the fluctuations is less.
How this works my varies between different brand, board and chip, for example my Evga P55 FTW do a double post before it starts and thatÂ´s EvgaÂ´s way to try set the right clock skew automaticly between the CPU and the PCH.
One have do a lot of trail and error with ones gear to find whatÂ´s working the best.
Hope it helped some
Low VTT voltage have very little to do with what CPU frequency one run, itÂ´s more about how high UnCore frequency one run, with a lower Bclk one got lower UnCore and that put less stress on the IMC even though one might run 1600+ on the ram, less stress on the IMC, less voltage to feed it.
If I run Bclk of 133, UnCore 2400, CPU ~4000 and ram at 1600C7 I can run IMC voltage at ~1,15 but when I start to rise the Bclk the UnCore rises to and I have to follow with the voltage even though I try to stay with the same ram frequency, so thereÂ´s nothing magic about it, in my opinion itÂ´s pretty normal.
ehume, thereÂ´s something thatÂ´s not right with your LinX run at Bclk at 167, the fluctuations is way to big, maybe something in the background that interfere or to low vcore.
@skfurr: Those temps are dangerous. I would keep your max below 80C.
@Ransom: Fixed .
