Msi afterburn and bf3

[Nathn]

Hey guys,

I've over clocked my gigabyte gtx 580 3gb with Msi Afterburn (2.2.3) to the settings of

1.1/900/2200 - this was stable with unigine benchmarking..

Go to play BF3 and within 30 mins or so of playing it I'll get cut out from the game.

Is this a known case for BF3 to cut out like this even when over clocks show as stable from benchmarking software? I realize BF3 requires a lot of GPU power..

Do you guys just keep turning it down until stable? Should I be leaving voltage where its at and gradually turn down core clock or memory clock or both?

Has anyone else come across this and overcome it? Could it be that I'm not running the latest version of Msi Afterburn? my graphics drivers are up to date.

Cheers.

without your system specs its hard to tell were the problem might be, as for bf3 its very sensitive to overclocks. have you attempted to run bf3 at stock clocks?, if so is there and lock up or crashes etc

Knowing the CPU/cooling you have would be helpful, i use msi afterburner to bring my 560 superclock from 850 stock speed to 925, and i have yet to get it above 81c in BF3, and even 81c takes several hours. I do notice my phenom 1055t starts to cause stuttering after a few hours though. Not unexpected, as it's on stock heatsink and not overclocked at all. But i havent been booted from the game since my athlon dual core days

BF3 doesn't seem to like overclocks very much, my 7950 runs at 1150 at 1.187v for every other game including Crysis 2 and benches, but not BF3.
I get the same prob as you, about 30mins in it just freezes or closes by it's self. To get it "BF3 stable" I have to put the volts up to 1.197v.

@Nathn : BF3 is never as stable as the bench's matey. Maybe add a few more mV ?
How many volts have you got that overclock on ?

You can't really compare the 560 to the 3GB 580 Rich, they clock differently due to the extra memory and stuff.

Hi,

One thing to be aware of is that Afterburner it's self can often be a cause of instabilities in certain games - especially if you use the video overlay for monitoring stuff during gameplay. It's not that common, and I think they've made some improvements in 2.3.0, but there can still be issues.

For example, Heaven 3.0 - a staple benchmark for me - point blank refused to run in full-screen anymore because of an option I had checked in Afterburner relating to handling modified shaders - as I use in Skyrim.

Oh, 1.1v for 900mhz core sounds reasonable - my 570's will do about 930mhz at 1.1v - I'd need to do the unlock thingy to push harder, but I'm too scared lol.

Scoob.

First off I would say to always run the stable drivers when doing these sorts of things. A few days ago I was benching my 580 and that included some bf3 tests and with the latest beta 310 drivers I was getting a 'dx11 device removed error'. Fortunately it wasn't due to my card dying just the 310 beta drivers, so use the stable 306 drivers for this.

I like to stick to a voltage which in my case is around 1.1V and then lower the clock speeds till i can find a stable speed. Although I mainly play at stock(832mhz), I can run 900mhz at 1.081V.

The actual gains in oc's i have yet to test for bf3, but in heaven I have had 940P at 832 and 1013 at 920 with a roughly 4FPS improvement.

At the end of the day I can run Bf3 and still be happy with the performance without Oc'ing and I'd hate (and this has happened many times before) for your game to crash while enjoying the game due to a Oc which you don't even notice an improvement, just for knowledge that you did Oc. Also, one time I was a tad too aggressive with the Oc's and i noticed that the ingame bf3 text was starting to smudge and it lasted for a few days so that scared me off quick smart.

Cheers
