BFG 7900GS unlocks!

I came across this from techpowerup:

and using Rivatuner, I was able to get my new BFG 7900GS OC to unlock from 20 pp/7vp to 24pp/8vp.

From a locked o/c speed of 585/1600 to an unlocked o/c speed of 570/1600 (couldn't go higher with the unlock) I got:

500 more 3DMark03 points
300 more 3DMark05 points
200 more 3DMark06 points
96.5 fps vs. 89.9 fps Half Life 2 Lost Coast Video Stress Test

I'm still testing, but I basically got a faster than 7900GT card for $187.99 CAD after rebate with taxes.

From what I read at Techpowerup, it's only the BFG ones that can unlock so far.

Very nice! :)

This keeps getting better....I did the volt mod to 1.5V using rear window defroster kit and I'm up to 650/1650--faster than a 7900GTO, 7950GT, and 7900GTX for $160 CAD ($139 USD).

that's sweet. without voltmod i got mine to 600/1700. but it came as 560/1650 so that's not really a high oc for me :). im too scared to do the hardmods :P

this could be the new x800gto2

The GPU volt mod wasn't hard to do. I used a paper clip to apply the rear window defroster kit liquid.
I am by no means electronically/electrically inclined.

Even if you make a mistake, you can always use acetone to remove it. Just ensure that the correct point(s) is/are connected before powering on.

I used this as a guide:

(I didn't do the memory vmod as I don't have a multimeter.)

Damn!!! And I just spent $230 or so for a 7900GTO lol.

Edit: Never mind, the BFG 7900GS is $184 at Newegg, plus my GTO has the nice GTX cooler.

:eek: Did you get it at Canada Computers? I've been looking for something around the $200 range to replace a X800XT PE. Saw the X1950 Pro for $200 on the Futureshop Boxing Day flyer.

Yes, I got it from Canada Computers.

That X1950Pro @$199.99 looks like a good deal also.

You get the lifetime warranty with the BFG, though.

I just removed the heatsink to re-apply thermal compound and found the core is a 7900GT one, not a 7900GS! It looks like BFG is just soft blocking the pipes via BIOS.

Awesome !

I love bios unlocks, there is always the anticipation that you saved a busload of cash as you boot up that game for the first time. :)

Nice! Yeah, love those unlocks. Going all the way back to the 9700/9500 days. :D

hehe it's a nice feeling indeed. i remember how happy i was when my Asus 6800GE (12/5) unlocked to 16/6. :D

I have a BFG 7900GS and after I enabled the bits and rebooted it still says 20 piplines.

is this only for bfgs? newegg has other brand 7900gs with rebates which make them like $150 cards

Yes BFG only, and only some BFG's at that

BTW, my BFG at NewEgg was $155 after rebate

Wow! That's a sweet deal if you can get them to all unlock!!!

Is it just a crap shoot if you get the right card? Anyway to get one for sure? I've got one sitting in my check out at newegg but not sure if I should go for it or not...I have a 6800GTOC --> Ultra so I know its a boost. But....meh.

I guess YMMV, but even if it doesn't unlock, you can possibly overclock for performance > 7900GT. The volt mod is still applicable as well for more headroom, just be sure to apply aftermarket cooling.

You may want to order from www.canadacomputers.com where I got mine, but that won't guarantee it either. (don't know if they ship to US)

Unfortunately they don't have any instock, and I can't tell if they ship to the US, but I would think that they would. Wonder if I have to pay duty. The card is $185USD at newegg....hrm.

I just got my BFG 7900GS from newegg... Just used Riva Tunner and... BOOM 24pp/8vp :) I Obtain 200+ Points in 3dmark05, but i want to know:

The Chip is a Real G71-GT ??? This is that RIvatunner says about:

- I´m a bit new in this world of unlocking cards :P what kinds of risks have the activation of this hidden pipelines/vp? (I dind saw ANY artifacts in my tests)

- Thanks in Advance :P

As long as theres no visual corruption you are fine, you run no real risks. Except possibly voiding your warranty, but it would be hard for them to prove that.

Thanks for the info...

Well I Just Confimed that is a G71-GT... I open ip to put some Artic Silver 5... and.. Voila It have a Real G71-GT Chip.. 24vp/8pp Working ;)

Welcome to the club! Yeah, the display adapter information is what Rivatuner is getting from the BIOS, which can mask the pipes as well as the identifying information.
