Could someone mod my 6600GT bios? :)

I have a point of view 128 MB 6600GT (PCI-e). A copy of my bios is attached below. I'd like 1.5 volts on the VGPU (is it possible to raise it further?)

One question: Ive never flashed a video bios before, but read how to do it. I've attached a copy as from savebios, but this saves it as a .BIN file. When I flash it, shouldnt it be a .ROM file :confused:

sorry for my n00bishness :p:

thanks :)

A graphics card BIOS can be or .bin or .rom extension. SO that is not the problem. The problem is that your BIOS is corrupt! Never use SAVEBIOS! It is only okay for older cards like GeForce 4 Series. You should use nvFlash to make a correct BIOS. Make a bootable DOS floppy put nvFlash v5.13 on it and then start your PC from that floppy and execute:
"nvflash -b backup.rom"

Then you zip up backup.rom and attach it here, and that will be a valid BIOS that can modded... ;)

Well, I managed to edit my bios using thr nvidia bios modifier and reflashed it. i set it at 1.5V but this doesnt seem to improve overclockability. With stock voltages, I could push it to 565/1197 MHz (VGPU/GDDR3). After modding the bios, the core only goes upto about 590 MHz, but i have to reduce the frequency of the ram to 1.18 GHz. Even at those settings, i get artefacts wheras with stock voltages and 565/1197 MHz everything runs OK :confused:

Did anyone actually get higher clocks after modding their BIOSes? And, there is an option to set it to 1.7V, but i didnt as i cant verify that this would work or if it would render my card unusable. Has anyone actually done this?

Thanks :)

Mmm, well I wouldn't using that modifier... It is not always correct at modding voltages and some people have had issue with their cards after flashing with a modded BIOS from that tool.

Can you attach your good BIOS here? Then I can have a look...

Thanks a lot :)

One thing that mat be worth mentioning is that it wouldnt flash using
"nvflah -p -u -f hack1.rom"

only worked with

"nvflash hack1.rom"

Using the first command, it came up with all the things like an explaination of the different tags, etc :confused:

Anyway, my BIOSes are attached below. Backup.rom is the original and hack1.rom is the one i edited.

Currently, im running on Hack1.rom. I experience no problems at the previous settings (565/1197 MHz). Should i keep this bios for the time being or re-flash to the original?

Thanks :)

Well you are using nvFlash v5.xx so those commands options have changed!
"nvflash -5 -6 newbios.rom" (Normal Flash)
"nvflash -4 -5 -6 newbios.rom" (Forced Flash)

And euh use NiBiTor to make any changes!

nibitor wont allow me to raise the voltages over 1.4V :confused:
however, the one that i flashed previously reports 1.5V in nibitor. Would using the nvidia bios modifier and changing it to 1.6V help?
08-23-2005, 08:21 AM

Yeps indeed that is because the voltage table of NVIDIA doesn't have a 1.5v setting and that is why if you use a multimeter you will still get around 1.4v on the GPU...

So i wonder why the voltage was set to 1.4 initially :rolleyes:

Ah well, what do you think of the speeds though? 565/1197 MHz? Not too shabby are they? :(

Maybe its time to get the old 4B pencil out..... ;)

Hallo especially moddolicous,

i have already save my BIOS and load up to MVKTech for a while, but nobody could help me, cause my card is very special. It is the "MEDION 6610XL": A special-version of the GeFORCE 6600 GT from MSI for a big German company like DELL. The card have a NV43 and 128 MIB GDDR3 from INFINEON on it. She runs very great from 400 MHz GPU & 400 MHz VRAM (DDR800) up to 561 MHz GPU & 513 MHz VRAM (DDR1030). But now she do not want more to clock higher. I have already buy a ZALMAN VF700-Cu and add some of this new High-End from Germany http://coollaboratory.com - but it did not help, the Card goes cooler down to 35 °C, but i hang still at the same clock, with artefacts with higher clocks.

Please moddolicous, could you take a look on my BIOS and higher the Voltage to the maximum (I think 1,4 Volt or 1,5 Volt is possible) and higher the Boot-Clock from [400/400] to [555/500] for all situations (2D, low power, 3D) in your Editor? I have save it with "savebios.exe": http://www.ttecx.de/VIDBIOS.BIN

Thank you very much in forward,
with greetings from Germany.

Tobias.

The BIOS saved with savebios.exe is corrupt as savebios.exe is not designed for saving the new BIOS (newer then the GeForce 4 Series). So pleas use nvFlash and then at least we can take a look... I didn't see any of this on MVKTech... (hmm might have missed that).

You have forget Mavke, check it: http://www.mvktech.net/index.php?opt...&filecatid=862
And now the Thread: http://www.mvktech.net/component/opt.../limitstart,0/

And now? Is there anybody who will there push my NV43 to the Limit? My Prescott is already runnin at 4,266 GHz - the GPU should follow. :D

I'll try and take a look. Is it AGP or PCI-E?? And also, did u say the stock clocks were 400/400? And lastly, if u can, try to back up the bios with nvflash. Savebios usually messes up with newer cards like mavke said.
