Flashing 6950 to 6970, truly bad? - Page 3

But... CCC still has the same limits, even after restart.
You've gotta drill down and confirm that whichever XXXX folder has the proper settings inside. The reason there could be a buncha XXXX folders, ie. 0000, 0001, 0002 is because one gets created each time a card is inserted. Thus you have to make sure the XXXX folder you're modding actually references a real card.

There we go, I did it on 0001, I forgot that I moved my GPU to a different slot on my Mobo. Thanks!

Now I just gotta figure out how to use RBE, haha.

Okay, every time I do something in RBE then flash my card, I end up getting a BSOD 0003B when I start up my computer. Does something look wrong in these settings?

Do not touch anything except unlocking the shaders.

Then go to Clock Settings, gpu registers, a window opens with 4 options. 3rd option from the left, default is 1.065 or 1.1. Change this to whatever you want... 1.2 is a good place to start, plenty of voltage while still very safe. Click ok and save as unlock.rom or whatever...

That's it.


*If you're on air, you can allow RBE to run a custom fan profile, but only if you hit the "set all fans to recommended settings" under Fan Settings.

**The reason there's two different default voltages is due to the two differences in quality of silicon. Some cores can run good on 1.065v while others need 1.1v.

***Don't edit anything else in any other manner. Doing so will = BSOD.

Yay! Thanks a lot man. I'm just gonna run AB for fan control.

So if I clock mine at 900/1400 unlocked, that would make it run faster than a 6970? Since that one has slightly lower clocks.

900/1400 would be imperceptibly faster.

Also when you open gpu registers, if the 3rd box says 1.065 that means you have the better core. You could run 6970 default clocks at 1.065-1.1v. If 900/1400 is all you want, then just up the voltage a wee bit... 1.1-1.15v.

Mine says 1100, sadpanda, haha. I can't run 900/1400 on the default 1100mv, it freezes up.

I guess if I have it at 1200mv, I might as well see how far I can go right? Haha. Is that a safe voltage for everyday use and gaming?

I use 1.2v 24/7. Imo if you don't go over 1.25v on air and are sensible, and you'll be ok.

Other than running the clocks out of spec, probably not.

OCP could be responsible for this. In my experience, the rapid clock changes it performs near the TDP limit can themselves be a source of instability. Also, while OCP is on, the TDP limit makes overvolting utterly pointless.

I've seen zero difference between unlocked 6950 BIOSes and a 6970 BIOS on my two 6950s, in either overclocking, or performance, when I set the same voltages and clocks with OCP disabled.

Well, I'm getting temps of roughly 79c +/- 2c during Kombustor when I'm running 1.2v, then roughly 2c less when running 1.5v. This is with my fan running at roughly 54-57%. Is that too much?
