I'm looking for some volt mods for a ge force 6200 (pci-e) now my google search has come up empty. Also if there are none will the 6600 volt mods work on this card?

there you go, the mods are super easy, especially the VDDR.
the VGPU can be grounded to the fan header if you need a ground, cause its so close the volt mod area for the VGPU.

volt modding me 6200 I came to these results...

initially my core was reading 1.335 volts, and 2.55 volts for memory.
with the bios mod to enable the temp sensor, I was getting about 36C at idle.
this is just plain old air cooling, but with a huge P4 heatsink on there.

the GPU mod went to about1.525 volts for me, after which, the screen just shows instant corruption, so the core doesn't seem to like much volts in my case.
however, I hear from my friend zakelwe, that his 6200 wont take any more then 1.4 volts at all.
we have different ISL chips between our cards, so mine seems more resiliant for voltages then his was.

for the Vmem, I am able to take it all the way to 3.25 volts, after that, it just results in instant crazyness. cooling doesn't help, so there just seems to be a limit for it on my card.

before the mods, I was hitting about 550/650 tops.
this is with 4 NS ram, not the faster 3.6 NS that some brands have.

after the mod, I can benchmark tops at 640/770.
thats plain old air, and got me a max of 8220 on 3dmark2003.
I haven't tried any farther yet.

right now, my card runs 1.44 volts, and 2.85 volts.
the new stock clocks are 575/700, for me, with all 8 pipelines enabled.

hi may I know what the bios mod is you used to enable the temp sensor. Thanks for the link reading it right now. My card will be water cooled and I will get sinks on the ram. I will perform the mod over the weekend then :) Also how do you tell which ram the card has?

to enable the temp sensor, you need NVFLASH, and Nibitor.

the latest versions of both programs.

first create bootable floppy drive, put NVFlash on there, reboot, let the floppy drive boot up, at the A promt enter...

Nvflash -B Backup.rom

then get in windows, and open the floppy drive, and copy and paste the "backup" rom form the floppy to your desktop for modding.

then use Nibitor, to open the bios and mod it. just go to the temp panel to click on the "6600 GT trick", and thats it. you can also change your default clock speeds with that program if you want, I set mine to 575/700 for it's everday speeds.

however, realize the temp sensor comes at a cost... your driver then detects the temp sensor and enables throttling as well :( so it's a trade off really.

to flash your card, just mod the bios, then save it as something simple, like X.rom

then reboot, let the floppy boot, then at the A promt, type...

Nvflash

then

the Bios name... in this case X.rom

it will ask if you want to update the bios, say yes.

this process is alot different for flashing PCI EX cards, and this is how I do it.
for flashing AGP cards, the process is alittle different.
at the A promt, I use the ...

Nvflash -p -u -f x.rom command.

if I want to try a severly different bios, I always wipe the bios off the card first, with the command.... Nvflash -e however, if you do that, do not reboot... not bios, means no screen.
so just flash like normal, after wiping the bios off the card.

I usually use Nvflash 4.42 for AGP cards.
for PCI EX cards, I just use the latest Nvflash out.

check mavke's site for all the tools needed.

do I need to do this on the computer I am working on or can I do this on another computer? I am asking this because I do not run windows on this computer and I only have my laptop that I can use to do that on. Also how can you tell if all 8 pipes are unlocked. Because I tried something and it worked but I want to be sure (again no windows to test with).

PS if you take my advice about grounding to the fan header, just make sure you ground to the pin that connects to the black wire, not the other one.

to flash the bios, you need to be on the actual PC with the card running in the computer.

to unlock the last 4 pipelines, just use Rivatuner.

I know you need to be on the computer but do I need to do the other things on that same computer like making the disk and etc. Whats the expected performance gain from running 8 pipes vs 4? Also how do I make a bootable nvflash floppy disk?

no you can make the disc on any computer.

no idea if Nibitor works on other OS's though.

performance gain?

well, my 6200, when at absolute stock, did 13,000 on 3dmark2001se.
thats with default clocks of 300/500, with a 2.7 ghz A64.

then unlocking the pipelines, took me to about 16,000 with no overclocking.
just had to make sure the card modded.
from there, I just modded the hell out of it.

now the card does about 21,000 on its everyday settings.
it's not much, but for $50 its hard to pass up ;)

hmm apparently nibitor doesnt support asus 6200's yet, I just tried to open my bios and it said device unsupported. Are there any other programs like nibitor that may do it??

Which version did you try?
Also, I think NiBiTor runs under wine in Linux.

13,000? That's not better than my GeForce 4 Ti!

it's a budget card.
but it's basically a 6600 still.
so it's got alot of potential.

it comes clocked at 300/500, but I have never seen anyone get less then 500/600 from the card easily.
so these cards are extremely moderatly clocked.

use nibitor 2.1

nibitor v16

Is there a later version and I will try it in wine it may work.

Also about the 3dmark01se it depends on a lot of things really.

One last thing can I unlock the pipes in the bios?

version 1.6 is the first version.

"18 September 2004"

version 2.1 is april 2005.

yes, you can unlock the extra pipelines via Bios, however, I am unaware of how to do it with this particular card, you need a hex editor, and need to know the exact line to mod...
I know how to do it, for a 6800, but not these cards.

heres an example of how to mod the bios of a 6800 to be 16 P from the start.

http://www.hardwareanalysis.com/content/topic/35401/

the same can be done for any card with masked pipelines, just gotta spend hours scouring over the numbers to figure out whats what :shrug:

you can also, just flash the card with a 6600 bios.
these cards are the exact same PCB and everything as a 6600, just its got some masked pipelines.

but remember, the version of the 6200 thats moddable is the A2 version.
Nvidia caught on about people modding these, and released the A4 revision, which is physically not able to be modded.
you can tell which version you have, by looking at the core.
somewhere on the core, it will say "A2" or "A4", if you got a A4, forget it, it's not possible, you'd have better luck modding it into a X850XT, haha...

Ok I will flash it with a new 6200 bios tomorrow and then over the weekend when I redo my water cooling I will see which core I have. Thank you all for your help I will let you guys know how it turns out :).
