Modified overvolting vbios of GTX460m on G73SW.

NVIDIA GeForce GTX 580 570 560 460 ATI Radeon HD 6970 6950 6870 5970 :: MVKTech :: On the Edge of Technology - Re:Need help tweaking the voltage of a GTX460M on G73JW - MVKTech Support Forums

Does anyone like to test?

(Only for Asus 192bit GTX460M, you can upload your own GTX460M vbios there, I shall make a check)

The voltage on the GPU is hardwired you can change the voltage in the Vbios but it will not actually change the voltage itself and will revert to the nearest hardwired voltage limit.

For instance on the 5870M

(0.95V and 1.15V) are hardwired so by flashing to 1.25V it will just revert to 1.15V or by flashing to 0.85V it will revert to 0.95V.

There's a risk to take, I guess I'll be the first victim.
Better keep my warranty at hand I'll try to flash it in a bunch of hours.

As I mentioned above modifying the Vbios will not modify the voltage you are going to flash the Vbios for no reason at all. It will specify the new voltage is applied but it wont actually apply it.

It even says that in the link you have quoted:

Need help tweaking the voltage of a GTX460M on G73JW

Thanks for posting, and we had already other visitors asking if the GeForce GTX 460M had the possibility to adapt the voltage through the BIOS and we have to simply say that with this one you are out of luck as there is no voltage selection available.

Well I guess that trying it's the only way to find out.
Since the gtx460m in the newer sandy platform is the v2 revision, who knows what will happen.

People have done many times which is the reason why I am telling you not to bother. Feel free, but flashing with settings that have not been used on an Asus reverse engineered hardwired card could potentially brick your card.

Either way nothing will change.

''The voltage will show under all hardware informative programs as being what you have to set it to in the Vbios but it will not actually be using the voltage that you have specified, it will revert to the nearest available hardwired voltage profile''

Dallers im sorry to say youre wrong.
Im typing from my g53sw with 825/1650/1650 and just had a full 3dmark11 run.

The Voltage tweak WORKS. Because previously i wasnt stable even at 815 with 1400 on vram.

I got 2480 with newer beta drivers which is a huge improvement. But theres a catch: my screen doesnt work anymore, im using an external screen.

I hope its not busted but just the vbios who makes mess, eitherway im about to find out.

BUT IT WORKS GUYS. IT DOES.

@Kingpinzero
You'd better provide your own vbios other than to use that for G73SW. Just to make it safe as Dallers mentioned.

Great news!
I am willing to modify your G53 GTX460M vbios.

Then the other numerous amount of people that have tried have clearly been wrong becaue your clocks are more stable which does not mean anything.

If anything the biggest difference you will see will be your temperatures which will show a significant increase if you have increased the voltage. .5 increase should show around 10-20oC under load.

I would make sure you are 100% sure before shouting ''It works'' to others on the forum who will run off to flash their Vbios. SVL7 should be able to clear this up he has done numerous tests on the JW with cards and Vbios.
