Jesus, Leeghoofd, i don't know what kind of magic was in your settings, but the PC is oh so completely different now!

I guess it was a mix of things which i won't have the patience to look up (still suspicious of something RAM related), but whatever, it's working perfect now!!! I'm just gonna tweak it up a bit more, make sure it's perfectly stable and then i'll post my results here. Meanwhile i can put some voltages i measured while testing:

- vNB in BIOS: 1,20, measured with Digital Multimeter - 1,24 (Increased 0,04v)
- vDRAM in BIOS: 2,22, measured with Digital Multimeter - 2,30 (Increased 0,08v)
- vFSB in BIOS: 1,16, measured with Digital Multimeter - 1,16 (No Vdrop)

Tested PRIME95 SmallFFTs and Blend plus 3DMark2006 - no worries @ 4050Mhz.

Thanks again, you got
