Best safe scenario for me is modded bios of your card with clocks at 880/1375 and voltage at 1.1v

Sucessfully flashed my Sapphire 6950 2GB to 6970.

How far overclock after flashed to 6970?
on a stock 6970, the voltage was only enough for around 910mhz... with 1.225v and voltage set to max in ccc i can run 960mhz 24/7....
good luck...
Hey guys, this works also on the MSI 6950 Twin Frozr II 2GB edition? Im about to buy 2 of them for a really neat price but only if I can unlock them.
Beside of that, how is CF scalling with this kind of cards and with the new drivers?
BTW, can I add a Physx card also?
Thanks and sorry for the Off, but I need some good and quick answer :)
Why would you want a PhysX card? any modern CPU can do perfectly fine for physX calculations.
It will work is the Twin Frozr II's are reference card design. I have no idea if they are or not. Any reference design card can be flashed to 6970. Non-reference design cards cannot.
I just bought a 6950 to replace the GTX470 I sold with my old computer. Ill let you know how the unlock goes in a day or two
The switch for the Bios 0 and 1 is not in the card, so I assume is not a reference card. Is there anyway I could unlocked?
I don't see a good work in physx calculations from the CPUs, so that's why I want a small dedicated Physx card, like a GT240, it would be possible to put a CF of 6950 with a GT240 for Physx in Windows 7?
Beside of that, is the warranty avoid if you unlock the 6950 even if it is a reference one?
I think it depends on the vendor, but it's possible that it does void your warranty.Quote:

I send you a PM zalbard :)
If it doesnt even have a bios switch, it definitely isnt reference design as the reference card has that switch. So you will not be able to flash with any bios you find as the car will not function with those bios. The only option for those cards would be to modify your current bios how you want and flash it to your card. Which since you are asking these questions probably means you have no knowledge of a bios so it would probably be a dangerous thing, especially with no "save me" switch
Received my HIS 6950 today, flashed immediately to 6970 bios. I used the stock HIS 6970 bios, with the 880/1375 clock speeds. Everything works fine. Only +10% additional power set in AMD overdrive tab in Catalyst Control Center (instead of the 20% most people do). No visual artifacts at all in 3DMark Vantage or 3DMark 11. Forced on: morphological filtered 4xEQ Edge-Detect AA, Adaptive multi-sample AA, 16x AF, 64x tessellation, high quality texture filtering, and vsync during the test. That should be stressing the GPU enough. Looks like everything is doing perfect.
So far looking stable with core OC to 940, mem OC to 1400. 20% power increase. Doing furmark Xtreme Burn, Displacement map, Post FX, 1920x1080 resolution, 4x MSAA run right now and through the night. Will update tomorrow to tell you if it passed that or not.
nvidia card as dedicated physx still need in many title of games
Card failed the extreme Furmark test sometime during the 8 hours, I wasnt watching. That was with 940 core speed. However it is 100% stable on the highest Furmark settings at the 880 core speed. A good unlock :)
youll need a slight volyage bump for 940mhz...
use rbe to edit the voltage
+.1v is enough to take you to 960-980mhz... 24/7:up:
got my diamond 6950 in the mail today also flashed instantly. Haven't ran anything like furmark etc to test but ive played black ops for a while, also ran vantage a bunch of times and heaven benchmark no artifacts etc at 950/1450 on stock voltage...however 3dmark11 goes to a black screen almost immediately in the first test.
Edit: Running furmark stability test now at 950/1450 stock volts.
upping the volts ;) not stable yet going to try 1.25
What does that power limit do,+10% or 20% ?
Might be different for others but I find furmark useless as a quick test, It'll pass just about anything I dial in & just about any voltage but as soon as you fire up 3D06 or Vantage it fails requiring a voltage bump to get it to run & complete.Quote:

I switched from 5870 to 6970.Quote:

The con would be noise (it's louder both when idle and under load) and higher temps (I haven't replaced the stock TIM, though). I am planning to watercool, so this will be a non-issue.
If you haven't gone CFX yet I suggest doing so instead of selling your card and buying a new one.
This is my personal experienceQuote:

hmmm, interesting. Almost like there isnt enough power to run at the full speed. Like it is trying to draw the PCI-E limit maybe? And then upping the power limit setting allows the card to draw what wattage it needs over the PCI-E spec? Maybe? Dont quote me on that but it kinda sounds like that to me. Anyone else have an idea on what the power limit actually does?
It limits the maximum power the card can draw, hence the name "power limit" :rolleyes: The card will lower its core clocks to make sure it doesn't go over the power limit, for example mine will run at 441-500MHz in Furmark when I crank the voltage to 1.3V and set the power limit to -20%.Quote:
