Unlocking Shaders on a 6950...

[Ddraig]

I got two 6950s and I was wondering if anyone has unlocked shaders and if it is possible to brick the cards? I'd rather not brick the cards since I just got them.

I've been browsing this guide. http://www.techpowerup.com/articles/overclocking/vidcard/159

And downloaded the TechPowerGPU program but the shaders section is grey'd out.

Any idea why that is?

Thanks,
Dd.

AFAIK, if you have a nonreference card, you can't unlock it.

And because it doesn't show the shaders I can't unlock it?

The shaders are what you unlock.

Do you got 6950 with 1 or 2 GB RAM?
Can you tell us how many Mh/s this 6950 can do without unlocking the shaders?

roughly ~420mh/s

The highest entry in this table is 314 Mh/s without unlocking shaders.
Or am I wrong?

Right, sorry. You might be able to overclock it and get it past 314 though.

I've got 2 6850 1G too. Any advice about PSU ? an Enermax modu82+ II 625W 25A+25A on 12V PCI-X cords may be enought ?
