Am I under powered?

post #1 of 15
Thread Starter 
Hi,

Little background first...I'm having epic problems getting BF3 running, I've never had a problem playing anything before and my rig seams stable. But on BF i can't play more than a few mins before it app crashes me to desktop.

I've tried EVERYTHING i can think of and more software and hardware related, All I can think of now is that i'm hitting the limit of my PSU and its creating the force close of BF as my card throttles.

My rig is as below in my sig, I've run an online PSU calculator and it says i need 588W but I could do with the opinion of an expect not a rough online guide.

If 588W seams on target and i'm running a 600W supply at 82% eff is only 490W+ Or is that wrong? lol

The game is still new so its a bit unstable on certain systems. I suggest getting the latest Radeon drivers that were released today and see if that fixes the problem. I see no way that the PSU you listed would be holding your 6950 back. A quality 700W should be able to do crossfired 6950's with ease. Good luck!

you should be fine, are you sure it's not a driver issue? I know I had to update my drivers before playing. Are you getting an error message?

When playing online my system does the same thing. I thought it was because steam and orgin was running. i closed steam and it seemed not to crash, however later in the evening it started doing it again. The worse part is i was 4kills and 0 deaths at the time and bam home screen. Hopefully they figure this out cause i get no error message or anything. I also thought it was a ram problem so went and bought a 8 gig kit and it did not do anything except load the game faster.

Power supply calculators are inaccurate. I doubt it's the PSU. Does it crash at stock settings? Are you on the newest drivers 11.10?

I have another thread open where I listed about 15 things i had tried and you'll have to trust me when I say i've tried everything.

So i just need advise on the supply...I noticed a bit of whine coming from my card too and in the past that indicated a failing PSU

Here, this is from my other thread

1. Uninstalling my ATi drivers with driver sweeper too, and reinstalling a few different versions (11.9,11.10).
2. Running different resolutions/refresh rates and on different monitors.
3. Changing the graphics settings from low,medium,high and ultra.
4. Turning off all my OC's and running all stock.
5. Turning off my firewall, virus and tuneup auto optimizer.
6. Disabling dual monitors and trying just one.
7. reinstalling punkbuster and running all the processes as admin.
8. Running the repair game thingy in Origin.
9. Closing all useless process's in the background to free up ram.
10. Disabling an MP3 splitter in my codec which can cause issue with games.
11. Run the DX diag from the direct x folder in BF.
12. Disabling sound cards
13. Uninstalling anti virus and firewall all together
14. Shouting and screaming at it!

Also tried some other things today
