I have to say, i'm a bit surprised that this card, with a rather modest power consumption and barely above your tested and working 680, brought the PSU to it's knees. Tough luck?
Glad to hear you finally found the issue.
Thanks. I was surprised, too. But after Newegg exchanged the card and the problem remained *exactly* the same, that led me to believe that another piece of hardware was to blame. I thought that a 750W PSU would be more than enough to handle my system, but, apparently not. I'm happy to say that I've worked my system over pretty thoroughly with the 1000W PSU in place and it has been rock solid. I suppose it's possible that the 750 was starting to fail. |
i am happy you got it working, going to order gtx 980, it comes with 800 watt power suppy, my gtx 660 runs coh2 great,so how much better will the 980 be?
I was running it on a GTX680, and as such could not effectively use AA. A few other graphics settings were not at maximum either. I am now able to run it with all settings on maximum and do not suffer any lag, even when things get really hairy on screen. My framerate during the performance test was above 60fps. |
I'm having the exact same problems. It's not hardware related, though it could be the driver. I've been looking for an solution as well all over the web, but unfortunately i haven't found a single one yet. The more i look on the web, the more i think that it is because of windows 10. I have these problems as well, since i installed windows 10 and coh2 brits expansion. So it could be due to either installation. However my intuitions says it's thanks to windows 10. I will let you know if i found a solution that works.
The resolution to my problem turned out to be a larger power supply. My 750W supply was not adequate to the demand. I upgraded to a 1000W supply and my computer has been rock solid ever since. If your computer is crashing back to a cold boot, that is definitely hardware related. A driver failure or software failure *should* cause a crash back to the desktop, not to a cold restart. |
"Windows 10 x64 Enterprise" found your problem.
Upgrade to Windows 8.1 or even better Windows 7 Service Pack 1
I'll assume that you've bumped your head (probably many times, with great force) for even using words like "Windows 8.1" (hawk, spit) in the same sentence. Yes, I love Windows 7, and abhor anything Windows 8. I would much rather suffer a lifetime of egregious jock rash than ever put any version of Windows 8 on anything that I have to touch more than once.
Once you properly demolish all the privacy invasions that Windows 10 brings to the party, it is a superb operating system. |
after reading this i am scared to upgrade to the 980, i think i will wait and see what happens
Don't be afraid, just be prepared. It's a fantastic card, it just has demands that must be met. In my case, those demands included upgrading my power supply from 750W to 1000W. My problems all went away after installing the larger power supply. Note that part of my troubleshooting effort including swapping in a different 750W power supply, which did nothing to resolve my problem. Duh. I can be blind sometimes - should have swapped in something with a different capacity!
For reference, here are my system specs:
Asus Z170 Deluxe motherboard
Intel Skylake 6700 CPU
Corsair H100i CPU Cooler
32Gb Corsair DDR4 RAM (4 x 8Gb)
Samsung 950 Pro M.2 250Gb SSD
Asus GTX980Ti Strix 6Gb graphics card
Corsair RM1000 power supply

Thought with a frame limiter you might get a way different result, sadly not :/
Do you know if the Strix properly ramps up her fan speed? I really got the feeling it doesn't.
_underscores's suggestion might be also worth a try. TDP at least changed with both cards.
Okay, problem solved. It was indeed insufficient power. I had the 980 replaced with an identical model (thank you, Newegg) and encountered the exact...same...#$%!$%...problem. I replaced my 750W power supply with a 1000W power supply, and the computer has been rock solid since. I ran the performance test having made no changes to the settings at all, and it completed flawlessly. I re-ran it, skeptic that I am, and again it passed. I cranked COH2's graphics settings to maximum, re-ran the performance test (twice) and both time it finished successfully. I've played several full games since with no crashes. I'm convinced that either A) my old power supply was having problems, or B) it simply did not provide enough juice. I'm leaning towards B because the performance test always crashed in exactly the same spot. There must be something about the load that the performance test puts on the graphics card when the SU-76 gets clobbered and explodes that pushed my old configuration over its limit. |
It could be a power issue. It looks within spec, but if the Corsair isn't doing its job under load then it's quite possible that you wouldn't notice with a 680 or with non-taxing games. Got another lying around?
Thanks for the suggestion - I tossed in a Thermaltake 750W power supply that I cannabalized from my other PC, and got the same result. For the sake of keeping my system as consistent as possible until a resolution is found, I put the Corsair back in. |
At least for now, my money is still on the GPU or some screwed up driver. Well, at least your CPU didn't die of boredom for a day 
Let's try the other route?

> set a frame limit of 60 (or even 30), set everything to lowest possible.
Make sure the frame limit actually works. (just in case... Steam has a fancy integrated FPS counter btw.)
Though now i can't get the mentioned Su-76 scene out of my mind, which sounds oddly specific.
Might wanna PM these guys in worst case:

UPDATE:
Using the nVidia Inspector to limit the framerate made a slight difference. Here's what I did:
I set the framerate to 60. In the game, I dumbed down ALL the settings to their lowest possible value. I launched the performance test, and it ran about 2-3 seconds after the SU-76 eats it. I saw the T-34/85 on the screen for about 2 seconds, then Ka-BLOOEY. Then, I cranked all the settings in the game to their maximum settings, ran the performance test, and the SU-76 didn't even get to where he gets killed before my PC crashed. Still undesirable outcomes, but at least there is a difference to be seen.
I also tried moving the video card to a different slot on the motherboard. That made zero difference. I thought perhaps it may be running into contention with my M.2 SSD, which also runs on the PCI-E lanes. |
No problem. I'm just a bit salty after reading these kind of threads way too often.
You have to start somewhere, but it still applies to your situation overall. We can just exclude your CPU most likely, that's it. (btw.: your GPU is factory OC'd btw., and has quite a history of causing problems)
Anyways, good luck with further steps, these kind of problems can be quite annoying.
Okay, so I put the 980 back in and just for giggles ran the COH2 performance test, and sure enough, the instant that the SU-76 takes a rocket in the puss, my PC does too and crashes hard. I ran four different stress tests - OCCT 4.4.1, HeavyLoad 3.3.1.230, Intel Burn Test 2.54, and prime95. My den is much warmer now, thank you. :-)
The tests ran my CPU and my GPU up to 100% and held them there for several minutes each, and no issues were revealed by this testing.
Do you have a stress test program that you feel would be worth adding to the above list? |
As expected. Those two settings don't really work together. You just get more FPS, but the same stress.
Anyways, the game isn't going "deep enough" to crash your PC, the stress or faulty driver is. COH2 is just rather demanding / badly optimized in general, and loves to cause the same results as a stress test.
For the last time: try the mentioned above. Or if you want to try the other way around: use a frame limiter with lowest settings.
kamk - I'm sorry if I've somehow ruffled your feathers, that wasn't my intent. I attempted to be gracious in saying that I thought your suggestion had merit but didn't apply in my situation as I don't overclock. You clearly have a lot of knowledge in this area, and I don't want to alienate you.
I'll try your suggestions and let you know what I find out. I won't be able to do so for a few hours as I don't have the 980 installed right now. I put the 680 back in place until such time as I have enough ammunition to make it worth shooting at this problem. |
