whats my problem!?!!?

[Nvidiaguy07]

im trying to OC my Q6600 to 3.6Ghz and my temps are not the issue, at full load under prime95 they are: 58 57 55 55 (idle temps about <25)

i had my v-core set at 1.475
fsb +.2 v
DDR2 +.2v
MCH +.1v
pci-e +.1v

everything seemed fine and i ran Prime95 for 19 hours with no errors.
i decided that 19 hours was good enough for me and decided to call it quits so i selected "stop" in prime95 and my screen immediately froze!!!!!

Im not sure what the problem is, its happened before, when i was OCing to 3.4Ghz it was stable for the same amount of time and then i went to open 3dmark and my screen would freeze up. The thing that cured it last time was just more volts but i could have just gotten lucky that it didnt freeze up after that.

I currently just increased the V-core to 1.483 or whatever the next notch is. Maybe that will do the trick.

Also im thinkin maybe my PSU could be the culprit. Its an X-connect 500watt and its kinda old (maybe 4 years).

If not then maybe my other voltages could be the problem. Id like to maybe increase the fsb or northbridge voltage but im not sure if that will harm my board.
Im trying to find out about these voltages in this forum but i havent had much luck

Any ideas on why this is happening let me know

can you post a screenie of cpu-z + prime95 SmallFFT

i want to see what your vdroop is.

If you've ever run a benchmark only to have your system crash right as it finishes then you have experienced the consequences of this poor setup.

aigomorla: im not really sure how to post a screenshot on here but i can tell you that i have a significant amount of vdrop and vdroop.
my bios is set to 1.475, in cpu-z at idle my vcore is 1.408 and at load while running prime95 it can drop as far as 1.36.

Im guessing this could be part of my problem and the article that syzygies posted on pages 5 and 6 shows that this is why it crashes.

My question is how do i control my CPUvid, is that even possible? im sure there is a voltage spike after i finish running prime95.

Is there anyway that upgrading my PSU can help limit this problem?

my cpuvid is 1.2625 so obviously this is too low. but i thought u cant change it?
