exact card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150521&Tpk=HD-687A-ZDFC

ok... i picked up this card not long ago.. and I am having issues with overclocking. Ok, even if i enable the Overdrive it can crash games like BF3

I contacted XFX and they are saying that the card may ne be able to handle overclocking???? sounds like a blowoff to me

here is the go between with XFX

[ 4/13/2012 1:42:17 PM] I cannot overclock the GFX card without issues. Actually, if i even enable the AMD overdrive. Games like BF3 crash. on my previous 4850 hd it worked fine... no good anymore. Help!

[KEVIN_C 4/13/2012 9:16:13 PM] Hello just to confirm if you do not enable any overdrive options the card works fine?

[ 4/13/2012 11:22:16 PM] Yes. And I have tried it in windows7 premium, ultimate, and windows 8. Using the latest catalyst drivers.

[KEVIN_C 4/13/2012 11:32:21 PM] Your system may just not be able to handle a 6870 overclocked. You may just need to keep it at stock speeds for best performance.

[ 4/14/2012 12:42:02 AM] Because of the psu? Hmmm. But then why does it crash when I don`t overclock, but just enable the overdrive?

[MARK_C 4/18/2012 6:01:10 PM] Hello , Power can cause instability and hinder overclockability but if the problem is only when overclocked then the card may just not be able to handle those higher frequencies. Thank you. Mark

so.. anyone else with this card have any issues with Overdrive??

Thanks!

unfortunately 6870s are poor overclockers. you may need to raise voltages. does you card support that? what frequencies are you trying to oc to?

i don't play bf3, so can't help you there. what i know is amd overdrive is not a good way to oc the 6870. like what Korg asked, can your gpu volts be adjusted?

i use trixx to oc mine. i have to disable amd overdrive first. you can seek help here . . .

surely someone there plays that particular game.trixx is very easy to use. one thing, though, i read that ulps needs to be disabled from within trixx. gl.

ok thanks.

at least with MSi and other utilities.. you can alter the voltage. I will check out trixx and see if it makes a difference.
