Topic: Optimizing ATI performance, 6950 in particular - page 5. (Read 52560 times)
I can't get above 900Mhz and 1.100 volts on my 6950's (unlocked shaders) at 380 Mhash/s. I guess I did not get these good cards like you guys got that can be overclocked a lot.
If only this:

Supported shaders unlock... I tried, can't get it to work.

Supported shaders unlock... I tried, can't get it to work.
I have 4 6950's and unable to get above 362mhash/s. I'm running unlocked shaders with 11.5 drivers and have tried all different clock/mem/volt/miner settings and unable to go any higher. I would like to get 400 per card. Am I missing something?
I have 6950 unlocked shaders, getting 408Mhash/s easily.
What I use:
MSI Afterburner - 1175v / 950 core / 450 mem / 60 fan (YMMV)
You might need to edit the config of Afterburner. Also you will have to lower the mem as low as possible, then close the app, then reopen. This will allow you to hit 450 mem. This was stable for me. 425 gave me artifacts. YMMV

Sorry if its sloppy I've been up for... 36hrs or something.
I believe he means 1.175... Gosh people should be more careful when typing.
That's what I've set mine to, and I get around 415 Mhash/s
you have unlocked card? tell me your setup with 1.175 ... it just works less when i change the volts from msi.
if i give it more volts, it drops the mhashrate this is trange.
im afraid of giving 1.75volts are you sure about this???
i haven't flashed the bios to 6970 and i dont have unlocked shaders (not possible)

hi,
i have a 6950 which cannot be unlocked. i messed with msi afterburner and @ 900/760 runs ok.
when i try to volt up so to go to 950mhz , i actually get less mhashes. how is this possible? i tried 1133v and 950 the system didnt hang but i was mining less. does this make sense?
your going need more v for 950 try 1.75 the stock 6970vcore) and put power tune at+20% form inside your ccc and btw what are you temps in they are high the card will cut back i have a 6950 which cannot be unlocked. i messed with msi afterburner and @ 900/760 runs ok.

Err not at all?
that looks normal for a unlocked 6950.

That's very impressive: may I know the details of your setup?Which system, linux or windows?
What program to overclock the card?
What software used to mine?
TIA!

probably wrong, I used RBE to unlock shaders by hand on http://www.gigabyte.com/products/product-page.aspx?pid=3693#ov , just checked 6950->6970 on last page, saved BIOS and ... I can't flash another BIOS anymore ... but it's unlocked

well I tried flashing the original saved BIOS and I can't ... Winflash gives an error, gigabyte vga tool says - same BIOS version
I thought I'd chime in with my sapphire 6950's performance
390-392Mhash/s
unlocked the shaders via bios flash
Core @ 965MHz with 1140mV
Mem @ 1250MHz
core temp steady @ 68C with fan @ 65% (4000 rpm)
no flags
this is with the stock heatsink and 2 120mm fans blowing on the card
ambient temperature is 20C.

Thanks Fasti,
I have been reading your post and playing with settings:
At the moment I am getting:
Core (MHz) Memory (MHz)
Current Clocks : 825 1250
Current Peak : 825 215
Configurable Peak Range : [600-950] [75-1350]
GPU load : 99%
and around about 315 mhash.
I'm keen to find out more about the possibilities of unlocking those shaders. If we both have the same cards we should stay in touch. I bought a new PSU the day after I bought my card. I got a XFX PRO650W.
Tonight though I am going to leave it underclocked at about 600 so I can get some sleep.
