Overclocking BSOD

i am oc'ing my phenom ii 955 b.e. and testing it using prime95. my temps stay below or just at 50 C. i can run prime95 with no errors or problems for a couple of minutes (10 or so) during which it will go through a couple of the tests but then, without showing any errors on any cores, i will get a BSOD. what would be the cause of this? why doesn't it have any errors on the cores before this and why does it take so long? could it be something else like the ram? the ram is rated at 1066 and is only running at 960.
 
are you thinking it may be too high or low? wouldn't that just give me errors though and not a full blown BSOD?
 
because overclocking causes instability. What do you currently have it set at (totaly frequency, FSB and multi), and what is the voltage of the chip set at?

Rather than type it you can always just put a screenshot of CPUz

too much work :P
i have been doing a bunch of different combinations. with a 220 core i can get up to 17.5 on the multi (max). with a 225 core i can get 17. with a 240 i can get up to a 16. i am testing the in between ones right now.

can having the voltage of the cpu set too high cause instability? i have it set to 1.5 v at the moment (yes i know you really shouln't NEED to ramp it up right away but i did that anyway since i didn't think having a cpu voltage too high could cause instability). could that possibly be it or am i just reaching the maximum clocks?
 
too much voltage shouldn't cause instability, but will cause alot more heat.

set it all back to stock, and raise the multi by .5 and stress test. If it is fine, raise it by another .5

Keep doing it until you get the system hanging or BSODing, then nudge the voltage up by the smallest possible increment and test again until it is stable, then nudge up a little again, rinse and repeat.

Once it gets to a point that you can't get it stable no matter how high voltages are, drop the multi to the highest stable and the voltage to the lowest stable and raise fsb by increments of 1 until unstable, then knock the voltage up by the smallest increment until stable or too hot.

Unless you got a dog of a chip, it should go above 3.85

It may be your memory causeing the problem, or you could put a slight overclock on your chipset

yeah i already did the multi oc. i got it to 17.5 and then i had problems with 18. i have not had any real problems with heat. with 1.5 v the highest at any time during stress testing that i got was 50 C, which isn't TOO bad. not spectacular but still not really that big of an issue.
do you think it might be the memory that is holding me back? remember, i am using ddr2 and it is rated to go up to 1066 (but hasn't gone that high yet). what would the signs be if the memory were holding me back?
