Help with my 6870 OC

post #1 of 3
Thread Starter 
Hi All,

I need some advice/input on this strange problem I am seeing with my xfx 6870 (non black). I used Stock came with the card BIOS 900/1050 is ok using 1.175 volts. I did an overvolt using the latest MSI AB and below are
my OC settings.


* stock BIOS OC to 950/1075 @ 1.250/1.2 ran furmark for 5 mins getting atficats (small dots) then system freezes.
* stock BIOS OC to 950/1050 @ 1.250/1.2 ran furmark for 20 mins then system freezes.
* stock BIOS OC to 965/1100 @ 1.268 ran furmark for 5 mins getting artifacts then system freezes and also
sometime I get a message about ati driver successfully recovered.
* stock BIOS OC to 930/1125 @ 1.175 this gets flaky gets black screen sometime even with just playing zuma blitz on FB, lol!!
* stock BIOS OC to 925/1125 @ 1.175 this one is stable


Does this mean I am stuck with 925/1125 settings or I just got a bad card? I bought this card at amazon 10 days ago and I have been playing with OC settings since I got the card. I tried setting the card to blow full speed thinking the card is getting overheated but no luck still getting those errors.


System specs:
Msi-p55a-gd65
Intel X3480 (default or OC to 4.3Ghz)
OCZ 2GB x 2 PC12800
XFX 650W PSU
XFX 6870
ATI Driver 11.5 (I will try to use later version drivers as soon as I get home today)




TIA!

Using later drivers will not increase your overclock in most cases.
I strongly suggest you either do two of the following things.
1. Use the highest stable overclock and leave it
2. Run stock speeds. The heat and power is not worth the tiny fps gain in demanding areas of games where the extra fps is really needed. This is true. I OC'ed both my 6970's and in a really demanding part of a game i saw a 1fps gain which made no difference to the feeling of game play however so much power was used.

Hi BradleyW,

Thanks for the reply. That's what I was thinking too of your #2 suggestion, but since OC is fun with CPU and GPU I get an itch of trying things out like most people do with their systems. But yeah you're right if I am just gaining 1-2 fps plus more power and heat then better to stay with stable stock settings.

Thanks again!
