Hi,

So for the last month or so MWO has been crashing when there is heavy fighting going on. All of a sudden my screens go blank, then kick to standby and the computer fans kick into super low. The only way to get going again is to reset the PC. Now I thought it was maybe due to the old computer that I was using but it just happened to me again and I have just built a new pc.

I was running a Phenom A2+ Processor, 8GB Ram, HD6950 1GB Vid card, Win7.
My new system uses an I5 3570K, 16GB Ram, same video card, Win8, clean install.

What can I send you to help diagnose this issue or is it something that everyone is suffering from?

I would suspect that it's the video card, its the only piece of hardware that you haven't changed, it sounds like its over heating forcing the computer in to thermal protection. look at you GPU temp. I had a similar problem when I was running 2- HD5770 cards. upgrading the card solved the problem.

[Korwyn Daemak]

I downloaded CPUID and at the time of crashing my GPU temp is only 80 degrees. From what I've read the thermal ceiling for this card is 95 degrees. Also I've been using this card for a long time and it's only in the last month that it's been doing this. Previously I could playing for hours without a problem.

When you upgraded your system did you upgrade the PSU?

Exact same symptoms here. It's a Graphics card overheat issue.

It's not the GPU temp, it's probably the VRAM overheating. From personal experience, the heatsinks for those are sometimes not carefully applied.

Turn or shut down the post processing to reduce some load on the Vid card. That's usually the big hitter.

If you can manually crank the fan speed before playing, try that. Sorry, not familiar with ATI's Driver set anymore.

Keep dropping settings until you've got stability.

How is it that MWO is the only game that causes my vid card to over heat? And how is it possible that in the year I've been playing MWO it's only in the last month that I am having this issue?

No I didn't upgrade my PSU, I am running an Antec TruPower 850, I didn't think it was necessary.

i use to crash at 70 degrees. did a clean up and reposition of sorts also lowered max voltage by 1% and i got the game to run at 50-60 degrees. havent had a over heat since then.

Crysis engine is heavily coded to use as much GPU resources as possible.

Beta, not optimized yet.

Also, I've got a niggling suspicion that every new driver set turns down the fan and temperature tolerance curves, to burn out the older cards. But I'm suspicious by nature, and I'm certain a company would not do that, just like making all the vynl records softer to sell more cassettes.*cough* sony *cough*.

My card crashes out before the fan goes into high gear, I had to use a utility to boost the fan speed.

Rule of thumb number [insert number here]: computer freezes and reboots are always hardware problems.

Point a fan at the card? Take the shroud off and clean? Remove the heatsink (very very carefully) an apply a little Arctic Silver (or similar) to all the contact points?

[Korwyn Daemak]

Well I would just like to thank everyone that replied to this. You were all absolutely right. My video card wasn't and doesn't increase fan speed as it heats up. I was looking for a good VC overclocking tool when I stumbled upon the one built in to Catalyst drivers. Manually increasing the fan speed while playing MWO has seemed to solve my problems.
Anyone using an ATI/AMD card that is having similar problems should go to their Catalyst Control Center and enable Graphics Overdrive found under the Performance tab. Enable Manual Fan Control and set to max. Don't forget to turn this feature off when you are finished playing. The fan at max is quite loud.

Or using MSI Burner can also be used to control fan speed and do it on a scale based on temp.

[Korwyn Daemak]

Can you use MSI software with non-MSI products?

[Tarl Cabot]

Yeapers!!!

[Corvus Antaka]

Sounds like a PSU overdraw problem.
