unlocked my 6800nu (16x1 6vp enabled)

Actually, that 'test failed' message can be overridden even after unlocking the card.

Hmmm, if RivaTuner now can enable pipelines even disabled in hardware, then I will try the Geforce 6800 LE action at a store I normally buy at for 200 euros. If I can enable 12 pipelines I have near Geforce 6800 GT performance and if I can enable 16 pipelines it probably will be between 6800 GT and 6800 Ultra. Am I correct?

 

I am surprised by the relatively low results some people here are getting with the 6800NU with the 16x1/6 VP differences, I did a rebench of 3dmark05 (Since I was doing the IQ comparisons earlier) and I got 4,400,


I wonder if it could be related to AGP aperture size, As I keep mine @ 256 megs these days since I have 1 gig of memory.

 

Not entirely. The 6800GT has 16 pipelines, a 350 MHz core and 1 GHz memory. The 6800 has 12 pipelines, 325 MHz core and 700 MHz memory. With some overclocking and unlocking some units, you can get 6800 performance or more (my brothers 6800LE gets more, it's close to a 6800GT). So you would get between 6800 and 6800GT.

 

Also bear in mind that a GT has faster/more memory. That WILL make it faster in a number of circumstances, and that mem size diff will REALLY make a diff at large resolutions with AA.

 

No luck enabling 4th quad. 6th vertex shader seems fine though. big whoop.

 

Hey better than nothing., Not like the additional Vertex performance is a bad thing for the 6800 series.

 

Full success from me; all 4 quads/6VP enabled, behaving this far 100% error free. Boy that thing turned into a little pixel processing (bandwidth hungry) monster. The increases in performance are more likely on average at default speeds at around 10% or so (because I don't intend to disable AA/AF either).

I clocked it to 340/400MHz (core intentionally modest) and the differences are in between 15-30% (I swear I could reach with a minor clockspeed push the 10K in 3dmark03 and the 30% is in Q3a/2048*1536*32/4xAA/8xAF; the first is by default a moot point for me the latter was already at the 100fps mark before).

Here's what MDolenc's fillrate tester has to say at 340/400:

Anyone got 256MB GDDR3@500MHz to spare?

A big thanks to Unwinder and anyone who contributed in making this possible

 

I also had full success 16/6. My 3dmark03 score increased by 800 points from 12/5. I tested 12/6 just to make sure all quads were working. 12/6 only increased 100 marks from 12/5.

 

I downloaded the new Rivatuner yesterday but I got scared that it might mess up my 6800NU, what are the chances of a borked card when it is displaying artifacts, can it easily be undone?

 

Full Succes!!!

Well, now I do not feel so beaten up 8)

Unwinder, you are my Hero

 

RivaTuner simply installs a driver that enables the pipelines when you boot Windows. You can uninstall the driver and reboot your PC and everything is back to normal.
It doesn't seem to modify anything about the card physically, I think it's purely a driver tweak, so it should be quite safe.

 

Sorry if this is a stupid question, but how can you get a 16x1 from a 4x2?

Thanks.

 

You definitely can't

The Geforce 6800 architecture has a maximum of 16 enabled pipelines in 16x1 configuration. The 6800NU has 1 quad disabled (12x1) and the 6800LE has 2 quads disabled (8x1). Rivatuner allows reactivation of those quads even if they have been disabled in hardware, and many people (well over 50% of the 6800LE owners so far!) are finding that reactivation of all quads is possible.

The Geforce FX is 4x2 architecture and the Geforce 6600 is quasi 8x1 (with only 4 ROPs) architecture, so obviously there are no pixel pipelines to reactivate.

 

Which GPU (4*2) are you talking about?

 

Mission impossible.
Or maybe...welding?

 

Damn, I thought there was 6600 in the topic title. :?

Thanks.

 

True. I would take the quad over the shader though. Still I got a massive 1.5% boost in the vertex shader tests in 3dmark03/05 !!!

 

just curious,

what do the artifacts look like for the people who have a broken quad, because i tried it and it seems like it only produces artifacts in specific areas, such as the water in farcry, and looking through glass in doom 3, games such as ut2004 dont have anything wrong with them.

also was wondering if anyone is getting stuttering when u overclock with the 16 pipes, think mine is abit short of power, 6800nu only have 1.2v dont they.

 

I've said it once and I'll say it again:

Artifacts are artifacts. They can vary quite drastically depending on exactly what the damage is that's causing them. If you check the Rivatuner forums over at Guru3d you'll see that people have very very different artifacts across the board, ranging from very subtle, to the more common white dots, to massive green lines in 2d mode.
