*** The Official ATI Radeon HD 6950 Overclocking Thread ***

Hey, I am running my unlocked 6950 at 880/1375 with no problems. My cpu is a q6600 oc to 3.0ghz and I have 4GB ram.

I don't have a link sorry, but in 3d mark 11 I get 4724 3d marks. But, what interested me the most was the graphics score and the physics score. I get 5197 for my graphics score but only 4690 for my physics score. Guess it's time to upgrade the Q6600 :-)

I am just looking at your score Easyrider that you posted in the first page of this thread, the 3d mark 11 link with your clocks at 900 and 1351. So for 20 less core clocks and 25 more memory clocks I am getting over 200 more for my graphics score?(4961 v's 5197) Wonder why the difference?

I ran the the benchmark with powertune at 0 and CAtalyst AI at high quality with the enable surfact texture optimizations unticked.
 
Guys, how are you determining max safe voltages?

I have a 6950 on its way, and would like to grab the unlocked shader bios and do some overclocking, but I'm a little unsure here - I've never gone any further than ATI Overdrive.
 
Just add the third 6950.
Oooo I love so much these cards :D

I seem to have crashes in crysis benchmark at anything over 900/1400 with 20% ccc power slider, i dont want to ruin my card and dont really know what im doing, mines unlocked to 6970 shaders

the thing thats tempting me to go more Vs is gaming at 2560x1440 on the dell u2711, only metro struggles really

should i try for more? im not really sure what the 20% gives me, if its 20% of 1.17, thats probably too much
 
boo, my 6950 flash cant even seem to finish the 3dmark basic bench at 20% ccc power slider, boo, temps are fine.. i have a poor card lol, my 5870 was poor too

what make was it?

I've ordered a second 6950 to cope with my eyefinity setup, but damn these things run hot compared to nvidia, thank goodness for watercooling :D
 
yeah I've pretty much given up on the idea of flashing/modding my HIS 6950 as it is not stable and crashes after a while no matter what I try to do to it. I keep it as a 6950 oced to 880/1325 and it runs stable as a rock! So far my experience with AMD both CPUs and GPUs is that you get what you pay for... however I am pretty happy with the card as it is
 
I can't seem to get over 840Mhz (CCC Limit), even with MSI Afterburner. Is the MSI tool only for MSI cards? Is there something else I can try?

you need to allow unofficial overclocking in the msi afterburner config file by changing the value from 0 to 1. That's what I did anyway and I was able to oc past 840 on the core... as for the memory I don't bother anyway
