Well, yesterday, for the first time since last August, when i put my computer together, i got BSOD...during playing Black Ops multiplayer, more precisely after maybe one and half hour during the loading of the next map...
Obviously there might be several reasons for that, and it happened only ONCE so far, but basically i suspect its either CPU, GPU as both are overclocked, or alternatively its down to PSU insufficiency...
Lets start with CPU, its 980x @ 3913 MHz with HTT and all power features on at stock vcore (set to normal, reads in BIOS as 1,25625, CPUz shows 1,184 at load)... i have this clocks only since last weeks, for last half of a year i ran it at 3,78GHz (one speedbin less) with no issues at all at same settings. So its definitely a possibility, although i tested it with 5 runs with maximum stress setting (using all 12GB of RAM) of INTEL BURN TEST and it passed it, saying its stable.
Then GPU, its GTX590 and i have it only for 2 weeks. I overclocked it to 670/1340/1800 MHz. I did not test it with any benchmark, but it could render for almost 3 hours with Octane Render, which loads both cores to max...and again it was stable.
Lastly PSU, i have a Seasonic S12D 750W...this might be bit on edge, with OCed 980x and OCed gtx590, but its a good PSU,those overclocks are both only mild ones AND most importantly i played Blops on only ONE of the GPU cores (multi-gpu was off). And i guess 750W PSU should be enough for such CPU + basically gtx570/580 + 2 SSD + 1 WD Green disk, right?
So my question is, from your experience, what is the most likely cause to the BSOD? Is there any way to find this out "immediately"? As the CPU passed the IBT, i reckon its more probably the GPU...but should i run IBT for a longer time period? maybe 10 runs instead of 5, or even more to be 100 percent sure?
What about those GPU stress test, Kombustor/Furmark, how do they work? Its guaranteed the comp would BSOD while running them, if its down to GPU overclock? If not, how will i find out? Will it the app tell me its stable in similar manner to IBT or what will happen? How long should i run them to be sure?
So far i clocked the GPU back to the factory clocks and plan to play the game again like this (in fact already did for an hour, no problem) for a few days and if there wont be any more BSODs, i suppose it would be possible to say, the culprit was the GPU indeed. Anyway i would still be interested in some faster, less "trial and error" method of testing.
Final question, is there any way, to create overclocking profiles for GPU? I mean it will automatically overclock to the 670MHz only when i run Octane and will downclock back to the factory settings, when i shut it down...
Thanks for your answers...
