RBE, 69xx, video clocks, and how they all fit

[tecnoworld]

I simply changed the brand to Asus...there can be a problem with RBE, then

 

[ss1]

i've edit the default clock in RBE 1.27 for HD 6950,but after flashed this bios,i cannot go in the windows,can any one help me?

OK a few things need to be said again:

You can only change Voltage on 69xx cards with RBE 1.27 Not clocks!
Changing the device ID is not going to give you more performance, you still own a 6950, 1536 shaders yes.
tricking the driver into giving more performance...NO
Yes you do need to shut down , not just a reboot.
The Powertune slider still plays a part when adding volts. You still need to push the slider to +20 to keep throttling away.

You can not (at this time) change your clocks of 6950/70 with RBE 1.27!!

I just tested your mod bioses with 1,275 volts... applied both of them but GPUz still displays 1.175 volts. Ist this a normal behaviour? If I save the bios then and examine it with RBE it also displays no voltage values. All in all I could rise the GPU overclock from 975MHz to 1000MHz but I still doubt if the new vcore arrives at the gpu.
What´s your experience?

You need to open GPU registers box in clock settings page to see the volts applied. I can assure you the voltage bump is real, GPU-Z reads from the driver info on these cards at least.
I use digital multimeters attached to the cards to monitor volts. The Bios volt mods do work if done right or Baggzlash would not have released it.

It's a shame these sigs are necessary to enable higher clocks in CCC. Going to try the ASUS SD range enhancement maybe, since my card is an ASUS. I've managed to OC my 6950 with unlocked shaders only to 880/1350 so far on stock 6950 voltages with MSI AB, and think I can reach 880/1375 like the 6970.
I would have loved to be able to flash those values in directly into the BIOS and have it run like that instead of through Afterburner, but looks like it's not going to be so easy with the CCC's limits.

So I guess I'm another that would like to see 6970 sigs work on 6950s so that one can at least go as high with the 6950 as you're able to with the 6970.

BTW, great app BAGZZlash and thanks for your hard work.

For all those that didn't know, you can bypass CCC limits and still keep PowerPlay with Afterburner, just check my post here:

^^ signed the petition, I've been following ULDT since first news. Even wrote to Dell, CEO and got a reply..

FUture looks good for us.

Well, if anyone is interested, there is a registry hack to unlock ccc.

It worked great for me.

Read carefully.

Hello guys...

I got today my new xfx 6970.
I read that u can't change the 3D clock settings and also can't change the upper limits (OC by bios), because after a flash the card will not function anymore. Is that true?
If yes, will come a solution?

That's true. Don't expect a solution because this is a driver issue, not a BIOS issue RBE could do something about.
For overdrive limits, try this new method currently in development.
