A8JS Overclocks, lets get some more power!

The ASUS A8jS is a great laptop, probably one of the most powerful for its size and price. I almost bought mine with the 7600 and Core Duo, but found a 7700 with the Intel C2D 7200 for $150 more on ebay. So i jumped on it.

This laptop is fantastic but iwould love to try to squeeze a bit more out of it, ive heard overclocking is possible via windows but for some reason i cant get it to apply it always resets everytime i apply the overclock. ive tried using all types of hacks to enable it but cant get it to work.

i used to own a Dell Inspiron 9400, which i modified to an XPS M1710's speed. It was a great bang for the buck, and faster then my home system but it was just too bulky for actual travel. Plus it was kind of cheap design. But it did have a powerful 7900GS, but the card was locked from being overclocked in windows XP. So we (the 9400 notebookreview.com forum peoples) had to boot into dos and use Nvflash to hack the bios.


quickly if you dont know; Nvflash is a 3dcard bios reader,writer it can create backups of your nVidia cards bios and can also write a new bios to the card. This can only be done by booting up into a DOS prompt its the only way to directly access the nVidia card's bios while its not being used for anything else.


The bios stores info like the clock and ram speed and other factors as well. The Dell crowd figured out they could apply the 7900GTX bios to their 7900GS's anyone with an Inspiron 9400 with a 7900GS could flash their card to a GTX And get XPS M1710 speed for cheap. This also allowed them to overclock their cards and bypass the overclock lock that Dell put on the cards in Windows or Vista. So someone could make a bootable cd with nvflash on it, download their bios, boot into windows use an nVidia bios editor NiBitoR, add an extra few mhz to the ram and GPU, then burn another cd with Nvflash and copy the bios to your card. Sounds complicated and tedious huh?

So some kind individual made a cd with a TON of 7900GS and 7900GTX bios's each one had increased clock settings and was labeled. So you would have the cd with nvflash on it, a dos boot image and a bunch of bios rom images such as; 400V500.rom, 405V500.rom, 405V505.rom, 410V505.rom etc..... each file was an increase of 5mhz over the other one so you could easily boot into dos with the bootable cd, apply a slightly higher mhz bios to your card, test it then go higher.

If someone could start me off with one 7700 bios i would go from there.


Also whats your favorite fastest 7700 drivers?

 

What program were you using to overclock?

From my experience, ATITool (v0.26) on my Vostro 1500 is easy mode to overclocking. From 475/400 to 545/535 on my 8600GT.

 

Here is my understanding. I could be wrong on the A8JS because my previous experience was with Dells. FWIW:

Most laptop GPUs can be overclocked a number of ways. There are 3rd party utilities and tweaked driver versions that expose previously hidden overclocking features - but there is a problem.

On laptops the speed is not always the limiting factor. Often the GPU is throttled based on heat. So for example, you can overclock the GPU and run faster for a short period of time, then when it heats up it will automatically reduce the speed to keep cool. In this example you may run faster at a slower clock speed because it won't have to throttle.

To take this to your advantage, improving the cooling of a laptop can allow for greater speed and overclocking. Improving the heatsink, using a supercool fan under the laptop, putting it on a laptop stand, etc could get you further than changing the MHz.
