Need help OCing my 6970...

post #1 of 15
Thread Starter 
Hey everyone,
I recently purchased a Sapphire 6970 and haven't had much success overclocking it much past the stock clocks of 880/1375. I haven't tried adjusting the voltage yet as I'm concerned that something might be wrong seeing as I can't even get stable at 930/1375 on default voltage. I'm currently using overdrive to adjust the clock speeds and I see the power control things goes from -50 to +50, I'm not sure what to do with it so I've tried it at 0 and +50 and its not stable on either one. Am I doing something wrong? What do you guys think? I'd really like to get a good overclock on this thing. I'd greatly appreciate any help.

Get MSI Afterburner. HD 69XX dont OC that good unless under water. Also you need to increase voltage.

I have afterburner, but it shouldn't matter if I use Overdrive or Afterburner if I'm not messing with voltage, am I right? Also, what is the best way to go about increasing voltage? In what size increments?

Same thing as I, my question is if I would get a arctic cooling accelero xtreme II would it help get stable clocks on default voltage since now with default cooling I cant even hold 950 stable on stock voltage.

maybe you are just expecting too much.

some cards might have freakishly high clocks on stock voltage, that doesnt mean yours can. both 6950 i have clocked can do around 900 on stock voltage, but thats it.

and as above, use afterburner, i had all sorts of problems with ccc/overdrive clocking

I'm running stable @ 950MHz core clock and 1425MHz memory clock with the voltage at 1174 with the stock cooling.
I have gone to 980MHz with a little more voltage but TBH there wasn't much difference in FPS maybe 4-5FPS difference in BBC2 so I dropped the specs back to 950MHz @ stock voltage.

Oh BTW temps are 70C @ 100% load and 45%ish fan. 40C on idle and 30% fan.

Did you use Afterburner to OC? I can't even get close to 950 on stock voltage, I thought I was stable at 920 only to start crashing in Crysis2. Also, which drivers are you running?

yeah.
11.10 preview 3 I believe. Which ever the latest ones as of 10-23-11 were.
Oh BTW Don't try crysis 2 its the buggiest game in history and wont even launch for me.

EDIT: What I found out was you gotta have the memory clock right in order to get a stable core clock.

EDIT number 2: According to This Thread. Two people that I can see, have Sapphire 6970's clocked at 910Core and 1425memory try that and see what happens.

Game runs fine for me at stock clocks, but it definitely started having problems once I tried to OC. I think I'm going to install the 11.10 V3 when I get home from work, maybe that'll help me.
