Upgrade to GTX 980Ti - COH2 crashes PC

Jump back to quoted post18 Dec 2015, 06:38 AMSSelke

I have been running COH2 on an Asus GTX 680 since the game was released and had no problems. I just upgraded to an Asus GTX 980Ti Strix and now the game crashes every time. Same driver, no change in graphics settings, and as soon as I run the performance test and the SU-76 gets hit, my PC hard crashes and reboots. I tried setting all the graphics options to their lowest settings, got the same result. Removed the nVidia driver and let Windows 10 x64 install its own driver (dated July 2015), same result. Installed 3 different versions of the nVidia driver, same result with each one. Installed the Asus version of the driver, same result. I put the 680 back in and the game runs perfectly, no crashes. I ran the graphics performance test in COH1 and it ran perfectly, no crashes. This leads me to conclude that there is an issue between COH2 and the 980Ti. I also tried the "Verify integrity of game cache" trick, that made no difference.

I laid out $650 for this card and dammit, I want to use it! If anyone else has seen this problem and has a solution, I'd be most grateful. I've researched this to a fine degree and haven't found a solution that works for me.

My system:

Asus Z-170A motherboard
32Gb RAM
Intel Skylake 6700K CPU
Samsung 950 M.2 SSD
Asus GTX 980Ti Strix 6Gb video card
Corsair HX750 PSU
Windows 10 x64 Enterprise

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?

Yes, I did. I ran the original Company of Heroes graphics test and it passed. I've played Need for Speed Hot Pursuit and Civilization V on the 980 and it worked beautifully. The *only* game that fails on this card is Company of Heroes 2. You know, the game I play the most.... *sigh*

I use windows 10 64bit and a 980ti SC and normally get 100+ FPS on max settings bar AA which is on low, no problems here.

Why AA low with a 980 ti ?

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.

"Windows 10 x64 Enterprise" found your problem.
Upgrade to Windows 8.1 or even better Windows 7 Service Pack 1

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.

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 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.
