I know, this PSU just doesn't put out enough amperage.

OK. card Brand name is DIABLOTEK

- Model : GeForce 6800 GS AGP8X 512MB
- P/N : NA/6800GXTD52-PM8370
- S/N : NA6800GXTD52V406000720
- Mode#V6800GS-512A

I'm tryed to get chip name with Nibitor 2.9a and there was saying NV41. So i'm so confused about this chip. Does anyone can recognise WHAT REALLY CHIP IS IT? And i'm now going to decrease core clock and test. Which me good luck ehe hehe.

When I get to the unlock screen I get this:

http://img150.imageshack.us/img150/4521/screenwv5.jpg

Notice the following:

• Description does not state "Pixel Unit 3" or "Vertex Unit 5" for bit 3 and 13.
• It doesn't say "enabled" for bit 3 and 13.
• There isn't a "yes" in the HW masked column for either items?

What should I do? The screen looks quite different from the one shown.

I think it's safest not to attempt the unlock in case something goes wrong...

Exactly what card do you have?

Yet another very interesting videocard.

Your card is a PCI-E core, running a HSI bridge, on an AGP board. As a result you have an NV42 core, which is made on a 110nm process.

As a result, you have NO unlocking available on that board at all. Don't even try, because doesn't have any unused pipelines on it at all.

The flip side is, your 110nm chip overclocks very, very well. 450Mhz should be very easy.

What are you currently clocking it to? and what drivers are you using?

Where the heck did you get this info from? I searched high and low to know why my card is a 42.

Life is tough.

Tbh I'm not overclocking at all. I have installed Coolbits v2.0 and ready to go. I am running the latest ForceWare Release 90 drivers (91.31) from the nVidia site.

So you reckon crank core clock uit up to 450 eh? What about memory clock?

[dsio]

Memory will clock up a bit, but not that much. Your DDR speed is quite good as it is. I got the info from what I know about Nvidia cores, and the technical information you pasted above. Its an interesting card indeed.

450 would be about average, and with some luck, a bit of cooling, and possibly a volt mod, 500+ is possible. Ive seen NV42s on water into the 600Mhz range easily.

Let us know how far you get with it.

[Deadman93723]

I have recently found out my problems with my 6800GS agp stem from not enough amperage from my PSU. I am upgrading my PSU from a Antec TrueBlue 480w, to a OCZ Powerstream 600w.

My question is, I can unlock my Pixel Pipes but I get a thin line of snow in the middle of the screen, with a better PSU and proper amperage, might this snow go away or are the pixel pipes just bad?

[Redroar]

If there wasn't enough amps then it would probably be more likely system instability than snow. I think artifacts are common of extra pipelines. As they aren't designed to be used, they can be incapable of displaying properly.

A small voltage increase may help solve your problem. Perhaps 1.5V or in that order, and an AGP voltage increase to 1.6-1.625V wouldn't go astray. If the voltage doesn't solve your pipeline artifact issue, it will still let you overclock more.

Failing that, you might just have a bad pipeline, in which case, you can still enable the extra vertex units, but leave that extra quad turned off.

Do you mean a video card bios voltage increase, or a system bios voltage increase?

[Samuknow]

It seems both..

Mod the card bios to 1.5 and then change the board bios AGP controller voltage to 1.6-1.625.

Hi Lord_nerevar could you post the bios of your Palit 6800GS 512?. Is your Palit looks like this? ,http://www.icomp.pl/thumb.php?sz=400...1145469769.jpg I have almost identical (Diablotek) card and have a lot of problems with this. Need bios from your card. Tnx alot.

I already have the agp voltage in the system bios at 1.6v. I tried 1.35v, 1.4v, and 1.5v in the video card bios, they all made the card go crazy. I don't think the voltage regulator on the card can handle more than 1.3v.

Mine has been fine at 1.5 for some time.

If it is freaking out I would leave it alone. It may be trying to tell you something.

You might be using too old of a driver to recognize the 512 GS card. Try the latest nVidia drivers and see if it appears...

Yeah, that I can't up the voltage, oh well. I have it running 12/6 @ 435/1160, not bad.

[Klick]

i was wondering since in 2 days im going to be getting a XFX 6800 GS extreme edition agp for $100 if anyone has done unlocking on one or can say what core it is because id love topull down a GT or Ultra for a fraction of what they went for not too long ago

[dsio]

It should well work. When you get the card, let us know how it goes for you.
