[zalbard]

So you me just try to unlock only the shaders?

Google is your friend!

It appears it won't and thanks.

As an update:

I tried using the Asus Overclock Edition BIOS in my cards earlier, and it does NOT work. 2D stuff works just fine but as soon as you fire up 3D it freaks out. It appears the voltage doesn't bump up like it should from the settings tables with the Asus O.E. BIOS. I went back to the 6950 stock BIOS until I can fiddle around with the project after finals.

To all the people with a successful flash: have you noticed any noise increase?(both in idle and on full load).

[EniGmA1987]

^^^^^ I wouldnt know, I flashed right when I got the card. But the noise is quite enough after the flash so I dont see what the big deal would be. I normally just leave my fan locked at 45% all the time and am fine. It is quite enough and provides enough cooling even under 8 hour gaming sessions while unlocked and overclocked even further.

[Neova]

@ Darkshadow - no noise increase at all. The fans become super loud at 90-100% regardless of flashing or not, but you can feel the difference with unlocking and a bit of OC. If the noise bothers you, just make sure all your games have VSYNC on or cap the FPS to your refresh rate. I unlocked and OC'ed to boost the min FPS mainly for smoother gameplay. No need to go from 100 to 300 FPS at only certain points.

Flashed a modded 6950 BIOS (just unlocked shaders) and was successful. I'm using Afterburner to keep the cards below 90* for the sake of the other components in the case with my little tiny build. I tried to just crank it up to 870/1350 but it blue screens immediately, so obviously my cards won't go that high. I'll have to fiddle a little more.

How do I unlock only the shaders in my vBIOS?
Is there a step-by-step tutorial somewhere? I suck at all this vBios modding/flashing haha....

Here is one

I heard the new Rev2 cards no longer have the dual bios and switch to select them. Anyone know if that is true?

That is true.

[BababooeyHTJ]

Does anyone other than Powercolor and XFX use the revision with no dual bios?

I had a bit of trouble flashing my Asus card. (2Gb ref card, slight O/C).
I tried to flash a 6970 BIOS to it, even used an Asus BIOS, but I got the subsystem mismatch error.
Only thing I could get to work was to use RBE to mod my cards own BIOS.
Got the shaders unlocked, but still at 6950 speeds.
Card seems to be working fine at the max O/C AMD Overdive will allow, 840/1325.

Although I have to say it hasn't made a massive difference.
Heaven benchmark went from 30.0fps with a max overclocked 6950, to 30.8 with max overclock and unlocked shaders.
So the extra shaders gave me 0.8 fps! I was kinda hoping for more!

What's the rest of the system ?

[Darxide]

What's the rest of the system ?

Asus M3A79-T Deluxe
AMD Phenom II 940, overclocked to 3.4Ghz
4Gb GEIL PC2-8500, running @ 535Mhz (1066) 5-5-5-15
2x Velociraptors in RAID 0

Also I ran 3D mark vantage again today, score has went from X9448 to X10330.

Does that seem about right?

You are limited by your systems that's why your improvements are nothing special.

[DontMakeMeEatU]

My Gigabyte 6950 from Microcenter finally came in today! I'm almost positive that it's a reference model since it has the AMD logo by the PCI-e slot....and that's all I'm basing it off of. I'm way too lazy to take the cooler off

I'm assuming the easiest way to flash this is with the mod from guru3D? And which bios is the best?

[st0ned]

Got a 6950 PCS++ after one of my reference 6950 went to RMA.

The core is a good clocker a bit better then my old 6950 reference. But the memorys are a really piece of crap... 1325 freaking Mhz .

Any chance that this happens due to 6950 pcs++ default bios ?

[Kenjiwing]

So I unlock the shaders on my 2 6950s.. it also unlocked the clock and memory for the FIRST card in my ATI CCC...

so I launched MSI and as soon as I turn on unofficial overclocking it BSOD's my machine.. it does this every time until I uninstall or remove unofficial overclocking.

Anyone have any idea why this is happening? Or any idea how I can OC my cards? Currently CCC only has the higher ranges on card 1 and not card 2.

Disable ULPS. google it if you don't know what how it's done.

[BababooeyHTJ]

Sapphire Trixx has an option to disable ULPS. Just make sure to reboot after you enable it. You also don't need to jump through hoops to enable "unofficial" overclocking or to modify the core voltage on a shader modded card with Trixx.

This was able to OC both of the cards.. I did see that even with the ULPS disabled (and a restart) on 2d mode etc my cards are still downclocking.. which I guess is a good thing either way.



Whats clocks should I be going for? My cards are under water ie voltage mem and core.

Damn program won't launch on my system. I hate Afterburner so I am stuck w/ CCC.


Kenjiwing, I had my cards @ 975/1250 w/ 1.3Vgpu. This is w/ XSPC full covers. Although they did start to bug out on me so I went back to stock.

It is written by Wizzard. I would just post in this thread and let him know about your problem. You might see a fix in th next version.

It really is a great utility when everything is working properly. I was getting sick of the hassles with Afterburner myself.
