At first, the problem I was having appeared to be limited only to TF2, thanks to Valve breaking the game with their most recent patches. The game would slowly degrade and then it would shut the system off entirely.
Unfortunately, it just happened in the middle of Starcraft 2. Since this game had been running just fine, and I just updated the BIOS, I'm starting to think the problem may be directly related to the overclock itself.
I enjoy the extra CPU/GPU power, but I have to wonder if the apparent system instability can slowly degrade and destroy my rig.
The Crosshair V motherboard has an "idiot-proof" overclocking system, which is why I went for it. Are there any other tools I could use to verify that the system is stable, and is there any possibility that what is happening is a shortage of power?
I'm wondering if my 850W PSU is having problems keeping up. This is the very first time I've ever done an overclock, so I am very much noob.
If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.
I'm afraid that that has done nothing but confuse me...
I have run my entire rig on a 850W Corsair PSU.
I have run long time stress tests on the GPU's, and CPU's, and the computer has not force booted.
During games, the computer has force booted.
After undoing my overclock, the system appeared stable, so I thought, until it force booted again, which lead me to believe that the PSU might be the root of the problem.
I have no idea about rails, or any of that. I have no idea how to check, or verify. So the link you just tossed at me is practically greek.
However, according to this chart: http://forums.atomicmpc.com.au/index.php?showtopic=264
My peak watts on all three of my cards is 510, and my CPU is a 95W unit, iirc.
That puts me at 605. That's 245 watts left over for 5 drives and 7 fans, neither of which use that much power. There's also the 20% overclock on my GPUS which might add another 100 watts or so, I have no idea.
If you are going to continue to be rude, just leave the thread. I am trying to figure out a problem, not sit here and get berated by someone who thinks he is smarter than I am because he apparently knows something I don't. You have no reason to talk to me the way that you are.
You are making an assumption that I didn't check. I talked to nvidia, and evga, and they said an 850W psu would do fine, provided that I had the proper 6pin connectors, but they clarified that it would "barely" do it. And yes, they were aware that I had three of these things.
Secondly, you didn't look at the atomicmpc chart at all, did you? "Peak Watts 510 for 3x GTX470's" And if P95 and OCCT dont stress a gpu, then how about you stop calling me an idiot and suggest something else I don't know, like a GPU stress test? Didn't think of that because you were too busy making yourself look big.
I'm going off of what I am seeing.
Surely, you can understand that.
1) Five solid months with the only issues being (I thought) related to the Valve Team Fortress 2 Update, in which the computer would mysteriously shut off, and this was only recent. So naturally, since this was happening to EVERYONE, I blew it off as a patch problem.
2) Starcraft 2, for the first time ever, caused a force reboot.
3) Just ran a stress test on my GPUS. No force reboot at 95% usage on all three.
4) Multiple sources telling me multiple things that ALL conflict.
5) I'm a noob at this.
If you were in my position, would YOU not be skeptical without someone else backing up what the only person consistently responding is saying? The only other person in this entire thread has said flat out that you're wrong.
What am I supposed to think, being generally naive to all of this, given all of the conflicting information?
I also see why I haven't blown my power supply to pieces. With all 3 cards together, my games aren't causing them to stress much. But while I still had my CPU overclocked, it was hitting the breaking point.
Looks like I'm going to be spending $400 on a thermaltake.
A little advice for the next person that you happen across with an issue like this:
Don't open up by calling them names or being uncivil. You come off as arrogant and don't get your message across clearly because nobody wants to listen to anyone that makes unjustified personal attacks.
