I guess my 1066MHz memory does not work at higher speed. Maybe a volt increasement to 2.2V would help...

But could my E8600 be defective? It does not respond better to a volt increasement. Higher then 1.5V is a no no!

Still 540x10 or 540x9.5 or 540x9 would be better then my 7x now...
What is the voltage requirement for your CPU at 7X ? if it's already pretty high... you can be sure it will need 1.5 and more for those speeds you want, your watercooling prolly doesn't cut it...(what are ya temps ?) And it still could be a bios flaw or setting you overlooked...

why don't you use 500FSB and try to stabilize 8X... then 8.5 and hopefully 9 multi stable... more prolly needs advanced cooling
