Geforce 6800NU
 
I've got a 6800 none ultra due this week, am I right in assuming riva tuner is thebest way to unlock the 4 hidden pixel pipelines? I heard that if you try flashing the bios the drivers still detect what card it really is because of a resistor configuration and I don't want to tamper with the hardware.
Do the omega drivers have the ability to unloc them like they do for radeon 9500/9800SE cards or are there any other drivers that do?

thanks

Rivatuner is an excellent tool for unlocking the pipelines.
Give it a go :)

GrahamGarside 13th January, 2005 09:34 PM

yeah I've been reading up on it and it and I think I'm sorted for how to do it.

woodeirl 16th January, 2005 05:54 PM

im sure your happy now with that new card buddy , and good luck with unlocking the pipelines :)

im sure you`ll achieve it with no problems

GrahamGarside 16th January, 2005 11:11 PM

well they seem to be faulty. theres no snowy pixels or missing triangles or anything like that but theres kind of a tint on the screen, kind of like a pink haze, I've seen some people giving advice that extra voltage can help (the gt runs at a higher voltage than the NU) but I'm dubious of this I might try it anyway and put it back if it doesn't. I don't know first my 9800SE wouldn't unlock now my 6800, some people get all the luck :)

Lazgoat 17th January, 2005 12:09 AM

Try, try, try! Give it more juice, whats the worst that could happen? :)

GrahamGarside 17th January, 2005 01:45 AM

kablam! :)

GrahamGarside 17th January, 2005 01:47 AM

gotta work out how to do it first, from what I've read I use nvflash to dump the bios, then nibitorv to change the default voltage settings then reflash with nvflash, but I'm not sure which version of nvflash is best to use, I've seen differant recomendations, plus I'm not 100% on what flags to use with it when flashing, don't suppose anyone here has done any 6800 flashing/volt modding?

I use nvflash442 while still in Windows!
You can use it from Windows cmd or create a shortcut to nvflash442.exe and put the parameters in it.
Get it here:
http://www.mvktech.net/index.php?opt...r&filecatid=42

I made a file flash.bat containing:
nvflash442.exe -f %1 -p -u -2
@ echo .
@ pause

Then create a shortcut called Flashme with the following:
flash.bat BIOS.rom
Change BIOS.rom to whatever the ROM is. It must be a 8.3 file name.

Double click the shortcut to flash your card. When its finished it pauses so you can see the result. The window closes when you press a key.

I've done over 10 flashes so far in Windows and it seems trustworthy.
As it uses 100% CPU, close all programs and make sure your system has finished booting (I've seen long pauses in the boot process on some machines, even after the desktop appears).

I understand if you prefer DOS ;)

Chernobyl

ps
To backup your current rom to saved.rom, use the following
nvflash442.exe -b saved.rom

woodeirl 17th January, 2005 02:17 AM

putting more volts in there will more than likley shorten the life of many components on the PCB.....

just a taught

GrahamGarside 17th January, 2005 02:40 AM

I've heard many people warning about this, in spite of core/ram cooling the electrical components can be a problem. I'm willing to give it a chance though.
and nvflash won't work in windows for me, do you mean win9x/me?

GrahamGarside 17th January, 2005 03:12 AM

well I did the voltage mod, 1.4v and rivatuner now reports vid 2 as opposed to 1 just about to try the softmod again

GrahamGarside 17th January, 2005 03:18 AM

nope :( same problem though it doesn't seem as severe, booo!

Pitch 17th January, 2005 03:33 AM

I guess it just needs some gentle persuasion

XeroHouR 18th January, 2005 12:37 AM

use 4 stairs, not the whole flight.

I hope I'm not alone here in saying...

Eh?

Chernobyl 18th January, 2005 12:59 AM

hehe. it could mean many things depending on your own perspective.
Why climb the whole flight if 4 stairs will get you where you want :)

Sorry you havent had success with your card. Perhaps you will be able to swap it out later when building a machine for a friend (of course give them a small discount!).
If you get a chance to try an NV5 or some other cooler, let us know. I'm eager to hear if it can help.

Lazgoat 18th January, 2005 01:20 AM

Hey Graham, what is this card like compared to your R9800SE AIW? Where did you get it from?

GrahamGarside 18th January, 2005 02:21 AM

oh it's ten times better than the 9800SE (well 3 maybe) got it from overclock.co.uk
but I do miss the ati's video capabilities, divX uses around 30% cpu time now compared with about 10% before and doesn't look as good. Playing Farcry on very high at 1280x1024 compared with playing it around medium with some high settings at 800x600 makes it all worth it though :) and unreal tournament looks...unreal :)

And it's funny you should mention that Chernobyl because that's exactly what I have on it :) It does kep it cool, running off the cards fan line it idles at 44-45C and on full load it reaches 55C
running off 5V it idles at 48C and full load reaches 58-60C and it can't be heard over the psu fan, though it's not quite silent, bringing it down to 3-4V should do it

My GPU runs 57C Idle and near 70C load with an NV5 running at 410/1100MHz, ambient 20C.
Those are very good temps you have!

Have you thought of modding your BIOS. I've done it many times on my old FX and the new GT. It didnt help me do any more than straight forward clocking did with the original BIOS, other peoples experiences have differed greatly...

GrahamGarside 18th January, 2005 02:45 AM

already on 1.4v :)
I don't think the nv5 does a great job cooling the memory though, those thermal pads look more like insulators.

Chernobyl 18th January, 2005 02:54 AM

I used arctic ceramique on my memory as it didnt come with pads!
Not sure if its any better as its quite thick in places to match the minute warping of the copper from when it was cut to shape. Maybe why they ship pads now?

If using paste on memory chips, be MOST careful not to get it on the Ram legs. I hosed a Geforce Ti500 with Arctic Silver 3 a while back!

GrahamGarside 18th January, 2005 03:09 AM

you don't need to be careful with ceramanique. Artic silver is slightly electrically capacitive, where as ceramanique is electrically insulating.
on mine it barely looks like the pads even plce pressure on the ram chips, and the coper isn't even warm to touch
I did the same with artic silver 1 on a tnt2 :)

Chernobyl 18th January, 2005 03:11 AM

I recently read that ceramique does have silver in it.
Could be wrong, u know the web :)

GrahamGarside 18th January, 2005 03:25 AM

its made from aluminum oxide, boron nitride and zinc oxide as far as I know (he says like he's not just looked it up :) )

Chernobyl 18th January, 2005 03:34 AM

Agreed, that was my previous knowledge too.
I'm keeping my ear to the ground as a lot of mis-information occurs for the sake of Marketing.

GrahamGarside 18th January, 2005 04:10 AM

zinc oxide, this stuff should make pretty good sun block :)

GrahamGarside 18th January, 2005 04:11 AM

keep you cool as well, they're marketing it all wrong

Chernobyl 18th January, 2005 04:57 AM

lol

Diaper-rash ointment as well. In fact, we used to us diaper-rash ointment as heat sink compound many years ago when we got into a bind.

Keeps your electronics fresh and clean. LOL :rolling:

Chernobyl 18th January, 2005 07:02 AM

I saw a review where they used toothpaste (or something similiar) in a heatsink paste group test. The toothpaste did pretty well !
Maybe an oil based toothpaste?

GrahamGarside 18th January, 2005 12:34 PM

toothpaste probabally worked well because it wasn't oil based. Plus the fluride particle are quite small

Lazgoat 18th January, 2005 12:49 PM

Hey graham, post some benchies for us! If you have any R9800SE AIW benchies to post alongside the FX6800 for me to compare with :D

GrahamGarside 18th January, 2005 02:32 PM

From memory the 9800SE scored ~3700 stock, ~4400 overclocked in 3dmark03. The 6800 scores 9267 stock and 10296 overclocked.
But it's in games where the real diffeerance is, performance is easily 3X the SE and sometimes more like 4X.
I never liked playing Doom 3 on my 9800, having to play at 640x480 on low settings defeated the purpose of the high end graphics engine. But now playing it at 1024x768 on high I see what it's all about.
Farcry also is improved so much, performance was a bit varied on the 9800SE, at a pinch I could manage 1024x768 with medium and some high settings, but some bits would push it too far and the frame rate would drop, I found 800x600 with 2xAA performed much better. Now I can play with very high settings at 1280x1024 and it looks incredible.
As does ut2004, very high settings at 1600x1200 compared with medium/high settings at 1024x768
It's the pixel shaders that really make the differance, any game making lots of use of them really shines and the higher detail settings don't take the same hit that the radeon did
I've not played X2 yet but from the benchmark I did it looks much better, and the flashing polygon problem the SE had is gone

woodeirl 18th January, 2005 06:10 PM

i have one of those NV coolers too but ive noticed than after about 4 months of so every time i turn on my computer the fan emits this real rough noise that if the fan was out of balance for about 2 min and then it disappears, i think il have to have a look at it and see.

did anyone else exp this kind of problem ?

and i use artic sliver 5 for the die.

whats the temps on load for that card (Nvidia) with full load ?

GrahamGarside 18th January, 2005 08:01 PM

running off the card fan header full load reaches about 55C, on a 5V line it reaches about 60C and thats at 1.4V
and that noise sounds like the fan might be failing, I think they're simlar technology to sleeve bearing fans, which use lubricant and this can dry up in high temperature situations

woodeirl 18th January, 2005 09:45 PM

yeh i was thinking about the lub thing alright do you think a bit of 3 n 1 oil will do the trick?
************************************************** ****************
yeh there really nice temps on the card mine runs @52 idle and about 57 on load,
