6800GS unlocked pipes?

I understand this is probobly a repost, but for my sake I need some clarity. From what I understand is that the 6800GS is almost identical to the 6800GT with exception to the number of pipelines. 16 vs the 12 on the GS. Now, my question is: can I purchase the GS (difference of almost $100 to the GT) and unlock an extra 4 pipelines ot increase performace? The core clock is identical @ ~370Mhz, but the memory is slightly faster on the GS @ 1050Mhz w/ the GT @ 1000Mhz.

Is it just a roll of the dice as to if I can or cannot unlock the pipelines? or is a really good steal and easily unlockable?

I'm looking at the BFG models, btw

Yes it is just a roll of the dice. Might work....might not. Worked for me np. I have BFG 6800GS AGP and locked:

3dMark03 10570
3dMark05 4270

Which was freakin great

Unlocked:

3dMark03 11700
3dMark05 5151

Which is greater still. As you can see it is a gamble but the card rocks either way.

I actually just bought one of these from www.chiefvalue.com for 197.99 with free 3 day shipping.

It should get here Monday, the UPS (sucks, I know) tracking says its only a state away, because it started in NJ. I was expecting it today, but UPS disappoints yet again by not being able to deliver despite being an hour or so away at 7:40am... (Laurel MD to Alexandria VA)

Anyway, on Monday I'll install it and test it out and see if I get any artifacts after unlocking the pipes and the vertex shader with Rivatuner (guru3d.com).

If the unlocking doesn't work all the way, it is still a good card beating the 6800GT in a few tests and matching it in the rest. Can't beat the price either!

hi i have EVGA 6800 GS PCI-E card do you know how can i unlock the other 4 pipes on the card ? thank you

It is easy, just do a google search for "unlock 6800 GS" and you'll find about 10 tutorials.

I had artifacts on mine so i had to turn them off. Good luck with yours. (it still is a very good card though)
February 13, 2006 11:35:06 AM

no they disabled it im pretty sure
February 13, 2006 1:56:01 PM

i was able to unlock the 4 pipes and 1 shader. but i got artifacts. so , the only option i have is to overclock the card.

you can't unload a 6800gs, i wouldn't try. they locked the 6800 pci express versions...
February 13, 2006 2:40:45 PM

As far as I understand it, the 6800GS PCI is locked in the hardware. Software unlocking will just give you crap.

Just be happy that you have a card that performs very good as is. If you have the money just buy another one and run them in SLI mode. That way your system would still be kicking ass!

But it can be done with the AGP version.
February 13, 2006 3:38:51 PM

For the gs, i would highly doubt it, as 6800's started to cut down on openable pipes. however the original 6800 agp can be unlocked to a full 16.
February 13, 2006 4:20:49 PM

all you need is rivatuner.
February 18, 2006 3:35:48 AM

Dunno if you guys know, but the AGP 6800GS is based on the NV40 core (same as 6800GT/Ultra), while the PCI-E 6800GS is based on the newer NV42 core. That's the reason why the AGP version can be unlocked but not the PCI-E version, and also maybe why the PCI-E version overclocks much better.

Yes, this is very much possible as the 6800 AGP's could be unlocked while the 6800 PCI-E's could not be. However, I would think nvidia learned and just lasered the pipelines right out in the updated 6800gs...

I just did this last night, using RivaTuner. Was very easy to do.

The card is now running with 16 pipes, so for now I'm happy. Played several hours last night, quake4, doom3, farcry....so far, no artifacts. fingers crossed!

AGP or PCIE?

OK - to clarify!!!!!!!!!!!!!!!!!!!!!!!!!!!

6800GS AGP is built on the same core as the AGP 6800GT and Ultra. At stock this card has 12 active pipes and 5 vertex shaders. Using Riva Tuner you can easily unlock 4 extra pipes and 1 shader to provide the 16x6 you see on the GT and Ultra. Clock speeds can be pushed higher on the GS but this all relates to the quality of the stock cooler or aftermarket cooler you add on.
Although unlocking is easy, there is no standard for success on the unlock - by this I mean its a 50:50 of whether you can unlock without artifacting. From personal experience I saw artifacting in Lost Coast with my 6800GS OC (BFG) unlocked (with just vertex shader opened I saw no artifacting). I have to wonder how many people really see NO artifacting after unlocking.

The PCI-E 6800GS is based on different architecture and the extra pipes CANNOT BE UNLOCKED. You can still do some substantive overclocking if you know your stuff.

I also saw some minor artifacting when I unlocked my AGP 6800 GS. Never tried just the sahder though. WIll try that tonight and see if it works. Mine was a little shimmer on some surfaces. But I did find that I couldn't OC my card when the pipes were unlocked. It would crash.

Wtf? 6800GS is not based on the architecture of the 6800gt/ultra series, as it is based on 90nm and the ultras/gt's are on 130nm. The reason the PCIE version can't be unlocked is because it was cut with lazers to disable such unlocking. I have a very powerful aftermarket cooler and I assure you I can't get 500mhz core speeds. An unlocked gs would actually be more powerful than a 6800ultra, however.

Update...I just saw artifacts for the first time, playing flight sim 2004. Right away I relocked the masked pipes, and returned to flight sim, and the artifacts were truely gone.

So, mine was imperfect.

Unfortuanate. Worth a shot though, eh? They probably patched all those AGP's =(
February 24, 2006 1:30:30 PM

Hey AK47,

I am trying to make it easier for those new to the 6800GS to understand and you've gone ahead and confused them all over again. Please appreciate the HUGE difference between the AGP and PCI-E versions of the 6800GS. Suffice to say AGP= unlockable & OCable, PCI-E = non-unlockable but still OCable.

I'm not too sure the AGP's are unlockable at all, after the whole unlocking of the 6800agp I suppose they patched it by laser cutting the pipes.
February 24, 2006 3:51:32 PM

YES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
THE AGP 6800GS ARE UNLOCKABLE! FFS!!!!!!!
I have one and yes they are ALL unlockable.....now whether the additional pipes are ok or result in artifacting is varied. PLEASE, if you do not believe me look elsewhere and check - you will find countless reviews showing this to be true. Try NewEgg and if that doesn't work take two bricks and clapped them together hard against anything you find between your legs. You see, sometimes the truth hurts ;) 
Please do not keep writing statements that are inaccurate, if you find reference to alternate observations cite them otherwise ppl are just going to think you are an idiot.
THE PCI-E extra pipes were laser cut. If you don't know the difference between PCI-E and AGP please go and look it up to avoid confusing others!
February 24, 2006 4:58:07 PM

What good are artifacting pipes? The guy a few posts above me has that exact problem, you know..
February 24, 2006 5:14:48 PM

how about those plain old 6800's from let say bfg, you can unlock the pipes and shaders, so why not a reg 6800 instead of a 6800gs?

agp of course

Nvidia isn't as stupid as we'd like to think. They want people to buy their expensive high end cards, rather than unlocking low end cards-so they disabled it (or tried to) on the newer chips. The gs came out about a year or so later than the average 6800, giving unlockers time to unlock and Nvidia time to block.
February 24, 2006 10:30:02 PM

Guys, if we just use the words carefully, then we will be communicating.

Dekkard is right, the AGP 6800gs is unlockable. I've unlocked mine.

Its also true that for me at least one game showed artifacts, so I re-locked it.

What the overall success rate is would be interesting to know. If anyone has a stable AGP6800gs at 16x6, then its worth reporting the possibility on these boards.

Update, in case anyone cares...LOL

I've installed a new driver, and I suspect what I said before was artifacts may have been a conflict between the 81.98 driver and the game....

Now I'm running 83.90 driver, and I've re-unlocked the pipes....so far no artifacts. Half life 2 crashed, but that may be a driver conflict again. I wouldn't expect a crashing application to be due to unlocked pipes.

No artifacts.

I doubt HL2 crashed because of the driver. HL2 is EXTREMELY bitchy about the smallest overclocked settings.

6800 GS AGP - 130 nm
6800 GS PCIe - 110 nm
March 6, 2006 6:50:57 AM

So I have the evga 6800GS pci e. May I get some numbers for the core and memory speeds which are safe to use.
March 7, 2006 2:00:20 PM

:cry: 
Just got a EVGA 6800GS AGP yesterday. Used 83.90 drivers. Loaded Riva Tuner 2 and unlocked pipes and shader. They unlocked fine, but I had artifacts in multiple games. Damn Shame!

My Leadtec 6800 unlocked and overclocked great! O'h well, maybe a driver update, or I'll just be content with the O/C....
March 7, 2006 2:58:41 PM

Yep, the AGP is 130nm and it is essentially the GT chip. It is unlockable. I have one, it is unlocked, and it has no artifacts.

Furthermore, I seriously doubt nvidia is going to take the time and energy to laser any chips so the pipes will be unlockable for the AGP GS. That is simply cost prohibitive.
