All I am trying to do is increase my computer performance and my BIOS is the original Dell ship with. I did flash with your version giving 1.05V and 1.10V. My GeForce 8800M GTX is the same as the other person. I know what you want, and that is also what we ar elooking for to help you but you don't want to listen so I will spell it out one more time. We need you own original BIOS's, you can say what you want and state that they are the same I don't believe it until I do a full HEX compare. Why, cause we know they are quite often believed to be the same but a lot of time it is not. So unless you are going to listen to us and do as we request, we won't really spend more time on your quest.

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/15 06:35Hi guys, I joined the XPS M1730 community a week ago and I am very interested in overclocking my GeForce 8800M GTX SLI. I already overclocked it to 650/2040MHz via nTune and it is very stable. Anyway, I read on your discussion that it can be increased to something like 740MHz. That should be very good when gaming Crysis or with the next Far Cry 2. I would like to post my BIOS so that you can tell me if I can use the BIOS you made already but when I try read the BIOS on NiBiTor v3.9, I get can't start driver: 1275. Is there another way to get my BIOS?
I'm using Windows Vista 64-bit, with the ForceWare 175.63, also GPU-Z tell me I have the BIOS version 62.92.2C.00.01. If you don't have the time to hel me, I would understand. But I have to try. Thank you very much guys!

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/15 08:45The NiBiTor driver error sounds like Windows isn't letting it run due to unsigned drivers, but I'm not sure if NiBiTor uses signed drivers or not. GPU-Z can dump the BIOS for you, click the button to the right of the BIOS version textbox.

Well that is indeed the driver signing stuff that is required from Microsoft and we are not going to pay Microsoft for that really as it is just stupid and we don't like to be controlled. So that is why NiBiTor can't work just as such on Windows Vista 64-bit due to the driver signing requirements. Now how can you dump the BIOS's is with nvFlash and a bootable DOS media. And this is because GPU-Z is not able to dump both the BIOS's from the GeForce 8800M GTX SLI version.

All programs that want to have some kind of direct access to the hardware need driver signing and for NiBiTor which is a free tool we don't see why we should be paying Microsoft to get this done, though if someone wants to pay for us... And GPU-Z will not dump both BIOS's of the SLI configured GeForce 8800M GTX SLI version so don't use that, as we really need both BIOS's.

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/15 16:22It seems that GPU-Z has been able to get my BIOS saved. As I can choose the device between both of my GeForce 8800M GTX's, I saved both files. Are these my real BIOS's? I'm using Windows Vista 64-bit and I can't run DOS software. How can I use nvFlash with Vista? Is it at least possible? Thank you! Dell GeForce 8800M GTX 512MB SLI Edition - Bus Type : PCI Express - Memory : 512MB

The BIOS's are just fine and they are completely the same as the other person who started the thread so you can use actually the same modified BIOS's as such. And your info you need a bootable DOS media, like a floppy or USB memory stick to start yout PC from and by that use nvFlash to be able to flash your graphics cards.

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/16 04:55It worked, anyway, when I was testing the different overclocking, with the 1.15V the first crash made a kind of strange damage on the game World in Conflict. The whole game is not well displayed, as the GPU was damage or something. When I saw that, my blood was frozen, thinking I destroyed my cards. But there are no problems in Crysis, and no problem in benchmarks. I am actually reinstalling the game to see if the crash just corrupted the game. I am now using the 1.05V setting, seems to stable at 660/2060MHz, I was stable at 650/2040MHz with normal BIOS.
Wow thank you god! I was using the very last version of ForceWware 175.70 and that was the reason of the bad display on World in Conflict. So, I am using the 1.10V BIOS. I would like to know if overclocking the cards directly in the BIOS is more efficient than overclocking via nTune. In this case, how can I change the frequency directly in the BIOS? Thanks a lot. I will come back with more feedback about my overclocking performance.

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/16 08:15Hi guys, I did not have enough time to test properly the 1.15V voltage, I could bench succesfuly at 790/2066MHz in 3DMark06 and got 15500 points. However 3DMark Vantage crashed on the second video test. What I noticed is that the more one reach the limit of the GPU's the hardest is to get a stable high memory overclocking. For instance 2000MHz on the memory seems to be the sweet spot for high GPU and memory overclocking.
What I need to tell you guys is that for using 1.15V and 1.10V voltages you really have to use a proper cooling solution for the laptop as the temperatures are pretty high in the range of 75-80°C at least. Today, I will get my Zalman NC-2000 laptop cooler and hopefully it will bring down my temperatures to a more acceptable level. Also proping up the laptop is helping a lot with heat and is a must in my opinion. When setting the clock up with nTune you have to pay attention to real frequencies for the cores and shaders as from 766MHz up shaders are set to 2000MHz which might bring some instability.
You can check the real frequency with RivaTuner dumping the GPU registers. Also while at it you will see the voltage which GPU's are using for the different performance levels. As a conclusion I think 766/2000MHz clocks will prove stable in daily gaming but will come back with feedback on this after more testing. Mavke, again, thank you for your help and support, without you we wouldn't have been able to reach the limit of our chips!

Re:Flashing a GeForce 8800M GTX, laptop running SLI configs? - 2008/05/16 08:23Ok! thanks for your useful explanations! What I finally need to know is does the BIOS posted by Mavke need to be changed to make the voltage effective? I mean, do I need to choose something in Exact mode like put 1.10V or 1.15V in 3D section? I hear people talking about Extra mode, but I can't acces it, is it normal? I use NiBiTor v3.9. Maybe with signed driver, I will access Extra mode?
