[QUOTE="My_name_a_Borat"][QUOTE="ATLReppa770"] Well, I forgot to tell you guys I'm using Vista Ultimate 64-Bit and when using ATi Tool I get an error that the Kernel Mode Driver does not seem to be running. A device driver is required for communication w/ your video hardware. So, I'm not able to do anything except scan for artifacts. Can you guys help please?

Yeah, Vista's just not compatible with ATITool. I'm not sure if Rivatuner works under Vista or not.
See, what I did was install an old 10 gig hard drive in my computer, put XP on it, then run ATITool. Once I found my maximum stable clocks, I flashed the BIOS, took the old hard drive out, and had my permanently overclocked video card running Vista.
If Riva Tuner doesn't work under Vista, yet you're hell-bent on overclocking the video card, I'd just do it the "BIOS flash way."
And what's the BIOS flash way?
Here's my 10 step recipe:
1. Get an old hard drive and install it in your computer. Install Windows XP, ATITool, NiBiTor, and 3DMark06.
2. Run ATITool. Increase the CORE clock speed 25MHz at a time for the first 75MHz (assuming that you're starting off at the default 500MHz of the GTS). Then, if you're still stable, continue bumping up 10MHz at a time, then 5MHz at a time. After each bump in speed, run the artifact scanner. Once you've found the maximum stable core speed, do the same thing for your MEMORY clock speed. I managed to get 630MHz on the core and 1.95GHz on the memory for my 640M GTS,
3. One you're sure you've found the maximum speed, let the artifact scanner run for an hour, then loop 3DMark06 three or four times.
4. Using NiBiTor, which is an nVidia video BIOS editor, save a backup file of your original BIOS. I don't have the program running in front of me right now, but I think to do this, you select "Read BIOS into file..." which saves your original BIOS into a specific location. A floppy disk is a good place for it. Name the original BIOS "BACKUP.ROM" or something like that.
Now, set your new clock speeds. You'll also see a "Shader Clock" or "Stream Processor Clock" header in NiBiTor, which is something you could not adjust in ATITool. Usually, 1.4GHz is pretty safe. I got mine at 1.46GHz. After you've set these values, save it as a ROM file. Call it something like BADASS.ROM or something silly like that. Remember, it has to be 8 characters or less, since you'll be flashing the BIOS in DOS mode, and DOS has that dreaded old 8.3 character limit. I first named mine a ten character file, and had one hell of a time trying to find out why the hell I kept getting an error message while trying to flash.
5. Now, create a bootable MS-DOS startup disk. This can be done right in XP. Save your new ROM file on the same DOS startup disk.
6. Download the latest version of NVFLASH. This is the DOS program you'll be using to flash your video BIOS. It's VERY important to make sure that your computer is NOT overclocked while flashing the video BIOS. Stability is crucial; if your system hangs during the flashing process, your video card may never see the light of day again. :cry: Save NVFLASH.EXE to the same MS-DOS startup disk.
7. Now, restart your PC with the DOS disk in the drive. At the DOS prompt, type NVFLASH BADASS.ROM. Of course, replace BADASS with whatever you named your overclocked BIOS file.
8. If it asks you for confirmation, sweetly tell it that you think you're far enough in the relationship you and yourPC have that you can trust it with flashing your GPU's BIOS.
9. Once done, remove the floppy, push alt+ctrl+del to reboot the PC. In XP, run your stability tester and 3DMark once again.
10. Once you're happy with the stability and (hopefully) higher 3DMark score, remove the old hard drive. You now have an overclocked video card under Vista! w00t!
