Unlock your ATI 6950 to a 6970 Thread

- Start date
Methinks some power circuitry somewhere is going to get a little warm this winter!
im with you on this, there is a reason its a 8 and 6 pin, i think 6950's flashed to 6970 are not going to handle the flash for long

Unless the 8 pin is for the extra volts needed when the voltage tweek software comes out?
Soldato
Thought 8 pin just provided extra earths and not additional volts?

/\/\/\/\/\/\/\/\/...I believe you're correct on that, I recall reading the same thing a while back about the 5850 and 5870 cards.
@ Easyrider, have you noticed any changes in heat output from your "new" 6970 at all. I'm just wondering if its pulling more amps due to the increased shaders.

65c full load when running heaven with fan @40 % this was the max reading in GPUZ
I have good case cooling though gentle typhoons
6 pins are rated at 75watt and the 8 pins are rated at 150 watt.
6 pin should be fine.
Its perfectly fine to boost powertune up.
Taken from W1zzards excellent article

"I did some additional power consumption tests and it seems that AMD's PowerTune power limiting system does not get "upgraded" by the BIOS flash. We see that even when modded, the HD 6950 (at HD 6970 shaders and clocks) runs into the PowerTune limit earlier than the regular HD 6970 which results in reduced power draw but also reduced performance in Furmark. With a power consumption of 202 W, the modded HD 6950 is well below the 225 W specification limit of the HD 6950 power configuration.
Once we up the power limit in Catalyst Control Center by +20%, we see that the modded HD 6950 draws 252 W, which exceeds its specification (225 W) by 27 W. This move also improves rendering performance by a good deal, so I would recommend it to all users who perform this mod and have a half-decent power supply. Going 12% beyond the specified power limit will not have any ill effects on your hardware and is well covered by manufacturing tolerances and overspeccing, but it reduces the possibility of stuttering or other performance slowdowns caused by AMD PowerTune.

you are correct.
Not really
Idle temps increased by a few degrees but nothing to worry about at all considering I kept the fan at the same speed.

How come I get 1600 shaders?

You need the correct version of GPUZ

Nice one, cheers. 
Now to do some testing.

Easyrider - nice job, well done.
So you think you have a 6970 now - but it's barely different to your OC'd 6950, so the question is, can you overclock your 6950?

Me too - my 6970 is still with OCUK, I'm wondering whether to call and ask for them to change it to the 6950 . Oh what to do...
Is this an educated guess, or are you sure?
Why would one card require extra earths, but not the other? It would be a bit daft for them to have to make the two cards different if there was no need.
Wizzard at Techpowerup has run extensive tests and concluded you should boost it to 20% and its safe.....
At the end of the day nothing is guaranteed, and if stuff like this is making you nervous you should just get a 6970 if that's what you want.
I wouldn't hesitate if I had a 6950, but I don't I have a 6970.

Why would you let one guy who seems to not really be sure what he's on about put you off?
Go read the excellent Techreport article and make your own mind up.

I'm in the same boat.
Bit p1**ed off with AMD really. There is now no difference between the two cards apart from the price? Great work AMD....
I wonder if OcUK will keep the 5% discount I got for ordering the other day and apply it to a 6950 - I spent the extra £60 as a treat to myself and get slapped in the face with this the next day.....
