6800 20 pipelines?

[imported_click]

Been hearing some rumors that theres a bios out there that gives you 20 pipelines for the 6800 series of NVIDIA cards -- any truth behind this or is it just a gamers dream ?

 

[Matthias99]

Uh, no. The 6800GT/Ultra cores (and the 6800NU AGP) have 16 physical pipes, as best as anyone can tell.

Maybe this new bios gives four more phantom pipes :laugh:

 

[MidasKnight]

No it's not the bios that can do that for your card. You have to manually take the GPU off the PCB and use AS5. Draw 4 small vertical lines then reseat the GPU back to the PCB. Use extra double sided thermal tape to reattach the GPU.

 

[SomeDude22]

Next Generation cards should have 20 and more pipelines

 

[IamTHEsnake]

Not physically possible, sorry.

if that's the case, people should have figured it out aeons ago

I drew the lines like you said, things seemed to work and then I got greedy. I added 17 extra pipe lines and colored in 10 extra vertex's. Now it won't boot. Think I need a 600watt PSU?

Sweet, just turned my gf2 into a 6800 ultra. Thanks!

 

[Melchior]

Actually, thats a misnomer. You have to draw 4.5 small vertical lines, and 5.3 horizontal ones.

 

[ScrewFace]

All you have to do to get the 20 pipes is to modulate the Flux Capacitor and reconfigure the Electronic Modulator. I hope this helps!

Beam me up, scotty.

The flux capacitor isn't working, captain!

no you see once you have modulated the flux capacitor you have to use coolbits "space Odyssey edition" and a little NOS to overclock your card to 88MPH

when thats done, you will now be able to complete the 3dmark 05 benchmark before it was even concieved, thus yielding the highest score ever

Tell me all of this crap is a joke

I used a soldering iron to attach a 80-pin IDE ribbon on the core. It worked! I now have 84 pipes on my 9600XT! I then soldered a 512MB stick of notebook memory.

My 3DMark score was so high I got an error message that said my 3.3GHz cpu wasn't powerful enough to calculate the decimal places in my score.

I used a hacked bios to run AA at 24X, and at 1600 x 1200 Doom3 was averaging 275fps!

At first I was having power supply problems, but after I modified a 220-volt line directly to the video card everything cleared up and ran smoothly.

honest question, i like the hardware side of a computer, but am still getting to grips with bits and pieces of info...

altho they are sold as having 16 pipes, i was under the impression there is only 4 actual physical pipelines but they are quad pumped, i assumed quad pumped was a more software/bios/etc based thing? if i wrong just say so, dont abuse me, like i say, honest question.....

if what i've said is true, would it not then be too difficult to pump them by 5? (cant remember how you write the 5 version of 4's quad...lol they are feeding us beer at work and achieve 20 pipelines?

There are 16 physical pipelines on the high-end cards of this generation (6800GT, 6800U, X800XL, X800XT and variants). The 6800NU and X800Pro have 12, although some versions of these cards really have 16 and 4 of them are disabled by the BIOS.

Also, running at clock multiples is almost always done in hardware. The only thing I can think of that has a variable multiplier like you're talking about is a CPU core.

 

[knyghtbyte]

if there are 16 physical tho, why does something like Rivatuner show 4 pipes....my 6800GTO from Dell is supplied as 12 pipes, but on the unmasking bit on Rivatuner it only shows 4 pipes with one being masked.....hence my question on the quadpumped bit....

not sure if im making sense here, they giving us beer at work..lol

try again....

higher end cards have 16 pipes, with the cheaper high end having 12 pipes....

BUT are those 16 and 12 pipes physically actually there? when you use Rivatuner to unlock the 4 extra pipes to make 16 on a Dell 6800GTO it shows in the main tab 12x1 pipes and 5vs, but in the section for unmasking them it just shows 4 pipes and 6vs, with 1 pipe and 1vs being masked, so you unmask them and then main tab shows 16x1 and 6vs........

so if there are 16 actual physical pipes, why wouldnt i have to click on on 4 different pipes in the unmasking section of rivatuner? i only click on 1 out of 4 and it goes from 12 to 16...

quad pumped is a term from somewhere officialish, either the Nvidia website, or a PC magazine, or the product boxing, cant remember now....

RivaTuner, I believe, shows quads -- groups of four pipelines. You can only enable/disable pipelines in groups of four at a time. Trust me, there are 12/16 physical pipes on these cards.

The only thing I know if that is "quad-pumped" is Intel's FSB. That's why they call it an "800Mhz" FSB when it really runs at 200Mhz and is quad-pumped. Maybe you're confusing pipeline quads with Intel's FSB? Stop drinking.

 

[knyghtbyte]

ok, so from a logical point of view, there are only 4 pipelines, just that each pipeline has 4 pipes within it.......kinda like a Scart cable can carry just picture, or just sound, or both

i think
heh

no its 4 quads of four

that means, theres 4 pipelines arranged in a work group, and theres 4 of these groups. disable one group and hey presto you got 12 pipes,

 

[imported_Kensai]

Mmm. I wish for a 20 pipeline VGA.

Exactly - otispunkmeyer is correct. There's still 12/16 pipes (for the 6800nu series / 6800GT/Ultra/etc.), but they are arranged in groups of four. It is not three or four "quad pumped" pipelines!

And it's not a simple trick of defining a new quadrant to get more pipes - the quadrant of pipelines are physically on the cards, so the 16 pipeline limit is defined by the production silicon of the 6800 series.

Long story short - just wait for the next generation if you want 20 pipelines or more .

no...lol

RivaTuner shows the raw (bios?) data of the card. it so happens that one bit enables a quad of pipelines (4 of them). Hence why there are four bits. For every bit set to 1, you have another 4 pipelines. 16x1: the x1 means there's actually just "one pipe per pipeline", I guess, if that's how you want to put it... before everyone attacks me for saying that, i'm just trying to put it in terms you can understand. sort of like bags of candy You have 3 bags by default, with 4 Hersheys in each. there's another hidden one in the drawer. so like setting one bit, you are taking one bag (4 candies/bag) out of the drawer, and "enabling" them. by the way, the bit isn't being unlocked. it's always been there set at 0 to disable the 4 pipelines by default. the thing being unlocked (by the bit) are the pipelines.

conversely, vertex pipes happen to unlock at one pipe/bit (i.e. you set one bit to 1 and it enables just one vertex pipeline). i'm sure that's right because gf6800NU agp (12x1 ps, 5 vs) can be unlocked to 16x1 ps, 6 vs.

by the way, "multiple pipes inside a pipeline" is properly called ROPs (raster operations). so, a 16x1 card has 16 pipelines and 1 ROP/pipeline. And, no, you can not unlock ROPs to have a 16x2 card (effectively 32 pipelines). I think. you can look at that as a "locked multiplier" (CPU analogy) on the video card.

now, if you had a normally 4x2, physically 8x2 card (i think), and you unlocked one bit (four pipelines/bit), you'd actually get eight more pipes (physically just 4 with 2 ROPs per pipe, something like that). maybe i'm just confusing you more... I'm not positive about the last paragraph in this post so don't assume it's right...

And you are correct too my friend. There aint gonna be a card with over 16-pipes until the next gen comes out, unfortunately.
