Okay guys, let me preface this thread by saying that I have read the overclocking guide stickied in this forum and have tried the various methods listed within it. I recently purchased a Q9550 and DFI X48-T2RSB Plus from NewEgg in hopes of reaching 4.0GHz+ with my Tuniq Tower. Things were rolling along smoothly... I managed to prime my system for 8+ hours at the following settings:
Vcore: 1.22v
DRAM: 2.2v
Timings: 5-5-5-15
FSB: 400
Multi: 8.5
Vcore: 1.26v
DRAM: 2.2v
Timings: 5-5-5-15
FSB: 425
Multi: 8.5
Then, I tried bumping her up to 450 FSB. This is where the problems began. For some reason, I'm no longer even able to POST, much less start to prime. I've tried backing off on the memory timings, upping the vcore to as much as 1.35v, upping the NB to as much as 1.35v, and changing the memory divider to lower the RAM speed to around 900MHz. None of these solutions seem to have worked.
I need suggestions please!
