I didn't know where to post this, cause my goal was to overclock my CPU but this is, most likely, a memory problem.

When I select the X.M.P. Profile in the Ai Overclock Tuner, and leaving the other settings at default values, my PC will only boot up untill the point the windows logo should appear and then... *poof*.... nothing, it just stops. Memory tests don't detect any faulty memory... and it's driving me crazy cause I can't find the solution.

I know I can do without the X.M.P. Profile but I still wanna find out what could be causing this issue, because when something does not work I wanna fix it.

Welcome SP...I do not use XMP. Put memory at default speed and timings. Disable C1E, turbo and power saving features. I got 4.5GHz stable with my 930 but hold off for King Deton. He can help you with XMP, if you wish.

I did some reading and found the answer, I copied and entered the settings that the X.M.P. profile uses manually and increased the QPI/DRAM Voltage and now it works fine, well still doeing some tests but it looks promising.

Also my i7-950 is overclocked to 3.8Ghz with CPU Voltage set at 1.3v and i'm probably gonna stay with that 'cause at 4Ghz my system is spewing out BSOD's with CPU Voltage set at 1.35v, seeing some people goeing to 4Ghz at 1.25v means that I probably didn't win the Silicone Lottery, or is it me beeing scared?

I might still need some advice on this but with "just" a Noctua NH-D14 and temps of 73°C maximum at 3.8Ghz it doesn't feel safe to go towards/over 1.4v, it might be because the thermal paste is still in the "Break-in Period" or it might be because of the type of method i've used, Vertical line method, to apply the thermal paste, might try other methods to see what those yield.

Anyway still have some hours to go to declare my system stable at 3.8Ghz but she seems mighty fine for now.

Awwww, your temps are good to 80 under load. 4Ghz will need 1.35-1.375V. I have 4.5GHz at 1.44Volts. Run daily 4.3Ghz at 1.38V.
