Graphics too overclocked or bad PSU - Page 2

post #11 of 12
Thread Starter 
Ok it crashed at the same point, So I guess I am going to be looking for the new stable GPU overclock and that some what rules out the PSU, though OC scanner doesn't really put much load on the CPU maybe 50% tops. And though I have fixed CPU voltage a idle CPU verses a loaded CPU is like 100w at the plug from my testing. I also figured out that my clocks seemed to take the dive from me messing around with that machine while I was doing the testing. As soon as a windows Aero feature would poke up while doing the testing it would almost instantaneously drop to the 2d level. Even a later time seemed to be caused be the dialogs that pop up in afterburner. I did also test the full stock card and it quickly went up to and leveled out at around 80c (with much lower fan speed of course 48%)

So it does seem to be Memory clock related. I can leave the mem clock stock and bring my Core back to the old +25% with no issue.

The other odd twist to this is even when I turn things down to what used to be my extreme stable oc settings (for folding) it now does the power off situation. I remember when I figured all these clocks out I had a bit of leeway at the ends with some artifacts and those sort of warnings before it would do black screen power down or bsod.

The graphics VRM over heating is a good thought especially if it was always on the verge of shut down due to heat, now its thermal paste is been burned up of over the year

The graphics card is almost exactly a year old...

As you said this model of OCZ was researched good when I purchased it and I am not really loading it up that bad either. Peak it sees ever at the outlet is 390w and that was with primed OC CPU and OC graphics with power unlocked testing. SO max that is like 320w in the PC

REVIVED!!! So since my last post I have not been doing much gaming, folding or pretty much any computer intensive tasks. So to wind down I was trying to game a bit on my machine but was running in to constant crashes even with stock clock on the GPU. I went to Frys got a new PSU tossed it in and all my issue seen in the earlier post are now gone! So all along it was the PSU after all. I have been able to bring my GTX465 to the orginal high and stable clock speed with no issues or power offs.

Wanted to update this thread so if anyone found it they would see the true problem and fix.
