The disclaimer (copied and modified from Sony Vaio SA/SB/SC/SE Advanced Menu BIOS Hack) :

There is no warranty or support at all. Don't use this if you are unexperienced with computers. All you do with this BIOS is on your own risk! Flashing is a dangerous process. Make backups of your data. Your warranty may void with flashing this hack. All settings in BIOS get stored in the flash rom. Disconnecting the RTC battery will NOT reset the BIOS settings since they are non-volatile. If you fail, there is no return since BIOS recovery is unavailable to new sony laptops.

The only thing changed from the BIOS is only on the GT640M LE, the rest remain.
BUT STILL, PLEASE BE CAREFUL AND TAKE OWN RESPONSIBILITY!

PROCEDURE :
-Unzip the downloaded file.
-Run the InsydeFlash file.
-WAIT until it finishes flashing!
-Restart your laptop.
-Have fun!

ADDITIONAL INFO 1 :
You may experience that when you run benchmark, games, or any application, but your Clock seems to be not at par as the Base clock.

Please follow the instructions
Make sure you set to priority to ventilation :


AND :
Nvidia Control Panel -> Manage 3d Settings -> Select the app you want to run full clock -> Select high performance nvidia processor on the option 2 -> Select Prefer Maximum Performance for the Power management mode.



OR

Nvidia Control Panel -> Manage 3d Settings -> Global Settings -> Select Prefer Maximum Performance for the Power management mode.
Now, all the app should run in Maximum clock.


You should be able to run at full clock afterwards.

ADDITIONAL INFO 2:
Currently there is a bug with GPU-Z, it will make your clock stays at FULL even when not doing anything(gaming, benchmark, etc).

The only way for your clock to stay or goes back to idle(135) is by closing the GPU-Z when not using it OR open up MSI AB at the same time if you want the GPU-Z to remain in the background.

This will definitely saves your battery when you're not plugged in.

Previously while waiting for svl7 to comeout with the link, I myself have created my own BIOS MOD.
Like Modder(SVL7), I only changed the Clock for GPU and Memory, no voltage.
Stock Core Clock and Memory clock is 500MHz Core, 900MHz Memory.

what does this bios do?

what does this bios do?

Sorry, forgot to mention.

It increase the base clock of the GT640M LE.

There are 4 version :
625MHz
735MHz
835MHz
950MHz

[serverxeon]

is it a permanent overclock? ie, everything my system boot it will run at that clock? or it merely raises the upper limit?

[Amal77]

is it a permanent overclock? ie, everything my system boot it will run at that clock? or it merely raises the upper limit?

Yes, a permanent base clock.

But in idle it will still run as usual (135MHz).

Something wrong with the Boost features.
It just wont work.
The modder need more time to figure that out.

Depend on which MOD, the temp raised from 4c to 7c.

[Supranium]

i dont see the attachment or link. Where is that bios collection?

[Enthusiast94]

Will this mod work on my model i.e. SVS15116GNB?

[Faceless Rebel]

I'll test this out. The base clock being 950mhz is pretty funny, if your GPU can't handle it and something in your boot sequence makes it clock up to the 3D clocks, your laptop will immediately crash I bet.

[Amal77]

i dont see the attachment or link. Where is that bios collection?

Please PM me for the BIOS.

Don't want to distribute to everyone yet.

Need to know whether it work for atleast 2 person.
It works on mine, doesn't mean it work on some.

[Faceless Rebel]

Okay, I have downloaded the BIOS files from CA and US sections of Sony sites. The MD5 checksums match, these files are identical.
