@ Bert, I dont know. If there's another program to log Voltages I'd certainly try that to see if they match. But better do it ASAP because 1.9V spikes on a 45nm CPU... This might not have a direct effect but it might most likely have a huge impact on its lifetime.

Little update from my side, I tried running 3.7Ghz with same settings but BSOD, then I tried 3.8Ghz with +0.1V and it BSOD'd as well.

Since it's like bed time now I did a quick run on my previous 3.6Ghz stable OC but this time with HTT @ 300Mhz. I was seriously surprised to see it booting without any up and it completely Intelburntest 5 runs without issues as well.

Im seriously in love now I think my 24/7 goal will be 12.5x300 (3.75Ghz), 2.4Ghz NB and DDR1200. I hope I can make it happen but now I noticed the long forgotten freedom of HTT and multi's I can always find a way around it if it doesnt work as planned But thus far Im more than happy

PS, does a high HTT put a huge strain on any parts btw? Im still scared less that something might blow up Guess in the end it wont have much of an effect on the MOSFETs, does it have on the NB or the SB?
