Need Help Getting my Phenom II x4 940 Overclock Stable

Getting really frustrated at this point...

250x14 fsb @ 1.45, HT @ stock, NB @ stock, RAM at DDR2 1000 5-5-5-15-2T, locks upo in OCCT after 30 minutes

200x17.5 fsb @ 1.45, HT @ 200x10, NB @ 200x13 CPU NB VID @ +0.35, RAM at DDR2 1066 5-5-5-15-2T locked up in OCCT after 30 minutes...

200x17.5 fsb @ 1.45, HT @ 200x10, NB @ 200x12 CPU NB VID @ +0.35, RAM at DDR2 1066 5-5-5-15-2T locked up in OCCT after 40 minutes...

Load temps in each run were around 51 - 53 max

It's like it's failing at the same point regardless of any combo I try...high fsb with low multi, stock fsb with higher multi...

What is also interesting is that I dont get a BSOD, rather the screen goes black, and I need to reset the CMOS to get the computer to run that symptomatic of anything?

What am I supposed to do now? Would upping the NB a step do anything for me (0.1)? What could be holding me back? The memory at DDR2 1066 passed memtest for an hour without errors..could it still be an issue here? I am fresh out of ideas at this point Any help from the pros?

This should be in the Overclocking section. In any case, have you also recorded temps for your other components? Your CPU is in a good range, but the same might not be true for your GPU for instance.

mods, this thread can be closed, i put it in the wrong section by accident. Thanks.
