Overclocking 9800M GS to 9600 GT Desktop speeds!

post #1 of 5
Thread Starter 
I have an ASUS G50VT with the 9800M GS. I have been running the GTS clocks forever (600/1500/800 vs 530/1325/800) and with the laptop reaching end of life I figured it was time to see what it can really do.

The card has 64 Streaming processors and a 256 bit interface which is the same of the desktop 9600 GT. The GTS clocks minus the memory are the same as the low power 9600. My ideal target would be the 9600 GT speeds.

The card was flash 640/1600/900 @ 1.15 volt and software overclocked to 650/1625/900. I ran ATI tool to test for artifacts and for the first hour use MSI Kombuster to artificially raise the temps even higher than they get with ATI Tool since its a bit dated. The last hour I burned the overclocked CPU 10 rounds. Keep in mind the air first cools the cpu then cools the gpu in this notebook so it has an impact.

The CPU-Z at the time (post burn) was showing speed at a downclocked multiplier so dont mind the speed reading, shoulda noticed/waited.

I pushed the cpu just a tiny bit further and ran a 3dmark06. My XP record on GTS was 10084. This was my best windows 7 pass at 9920.

I am back to 640/1600 and have to admit 650 isnt fieldable. I can in any given situation run stable on 640/1600 but 650 needs 1.2v with the laptops own cooling which is too high and hot. This test was done bottom panel off on a notebook cooler. I also removed the pwm pin to prevent the fan from throttling in case it decided to be stupid. The laptop is normally benched so its not an unreasonable setup but its also not normal.

I have the same laptop. You can unlock the 9800m GS to a GTS, as well.
In progress.

and all the GTS ever was, was a different clock/voltage, also apparently die size. The guide exostensa wrote for NBR and posted here too i believe under a different name calls it a bios swap. The truth is its just a change of clock speeds and voltages. Try flashing any GTS bios to a GS card nvflash will refuse.

Now the GT and GTX has 96 shaders and its a shame there not the same chip because it would be lovely to have the chance to unlock something other than an overclock.

640/1600 vs 600/1500 isnt as big a jump as it was from stock but overall a 20% over stock overclock isnt too shabby.

I will hit you up with something more specific later.

But use GPU-Z to download the bios, its the icon right next to the bios version. Then use Nibitor to edit the voltages and speeds. Make sure your changing the voltage and not just the VID name. You will need to create a bootable DOS flash drive to flash a new bios using nvflash.

You can software overclock the graphics card to some extent using either nvidia system tools or MSI Afterburner. Use this to up the clock speeds little by little and then something like ATi Tool or OCCT (OCCT has an option to check for rendering errors) to test the stability. You will only get so far without raising the voltage which requires flashing the bios on this. You can find something stable and flash that and or flash the voltage and keep on testing after you flash the higher voltage.

Not sure whats safe voltage wise but 1.05 is stock for most of the G50VT's and 1.1 is usually required to hit 600/1500. I can hit 600/1500 stable on 1.05 until it goies over 80c which of course WILL happen so i had to up the voltage.
