vMod for 6800 Go?...

Is there anyway of increasing the voltage to the GPU of the 6800 to help O/C more?...

My core won't go any further than 355...

However, the memory is blistering on this thing, it runs 850 all day long with no artifacts, it's a shame I can't push the core any higher!

Vmod on a lappy where cooling is already an issue = bad idea IMO.


Now with that having been said I'm sure it's possible somehow. Always neat to watch someone else try to blow their toys up! Let us know!

I'm working on it. As soon as I get the Ultra heat sink.

There should be no problem. Years before I overclocked the 700gogl of my Inspiron 8200 to > Geforce TI4400 niveau by using a voltmod...
With some changes in thermal management I think you can get the same GPU- Clock as the Ultra.

Does Dell lock the voltage to the 6800 Go in the bios or something? My core will not go over 355 Mhz at all....

Is there a Video Bios update for the i9300 to allow me to flash my 6800 Go to Ultra speeds?... My 6800 Go has the same NV42 core as the Ultra...

The memory on my 6800 is excellent, it runs at 850Mhz (1640Mhz Effective) with no artifacts at all!...

If I could push the GPU core up some more this thing would seriously contend with an XPS2.

I'm in the same situation, looking for a voltmodd. I REALLY want my card to go upp in Ultra speed.

Well I'm off home now, so I'm going to fit my 1.8 Dothan....

After I've done that I'm going to play around with moding the video bios.... I'll let you know any results...

Let me know the results of your 1.8/400 Dothan, as I'm replacing my 1.6/400 with something bigger, want to know if it works well at 2.4 GHz

Well no joy for me running a 1.8 745 Dothan in my Inspiron 9300

Pulling the laptop apart was easy, so was installing the new cpu with pin-mod...

I Booted up fine at default voltage with no problems, first run of SuperPi 1M, blue screen, reboot.... Pulled it apart again, pin modded to increase vcore... managed to get a 1M SuperPi run, failed on 2M...

Even when throwing 1.644v at it, couldn't even get a 2M SuperPi run so wasn't going to even try Prime... Ah well...

The chip I got was dated 2003, I guess maybe a newer one might work better?...

Anyway, have just ordered myself a brand new 1.7Mhz 735 Dothan so hopefully I'll have some joy with that...

9300 Volt Mod using NiBiTor

BACK TO GPU!!! I searched for days to find out that no one has posted any info on volt mod geforce 6800 go. So i tried it myself using NiBiTor. I moved the 1.1 volt's to 1.1, 1.2, 1.3, 1.4 by using the voltage table editor in NiBiTor. I made and saved several Bios's with different voltages and flashed them with NVflash. With little effect in my small increases i jumped to 1.2 and 1.3 simply using the voltage table editor and changing the 3d voltage settings again. My GPU temp went up about 2-3 degrees with each .1 volt increase so i believe this would confirm volt mod working. I increased it all the way to 1.45 however found that 1.3 ran the best. I tested using ATi tool to monitor for artifacts and rivatuner to monitor/graph GPU temp. Now my cards runs stabler at higher clock speeds with less artifaces and my 3dmark05 score went up vs using the lower voltage at same clock. Hope this helps people. Are there any other tricks i should know about to get higher clock speeds besides the volt mod.. help me out please h1me@mail.com...

Do you have the NV41 or the NV42 core? What clock speeds are you at now?
