Modified overvolting vbios of GTX460m on G73SW.

Aha you have a G53JW, anyway you can also find that in the link I provided .

 

Hi,

@hackness
I also have an Asus G73JW-DE with the following REV. 70.06.25.00.0B
Please patch my Vbios File to Setting2 on load( 0.9625v )

Thanks for your help

 

Done. Enjoy the new voltage.

Please help me overclock my Asus G53SW-XA1. This thread is so long and hard for a newb like me to understand. I bought my machine around 1 year ago (jan 2012). So am I going to be able to do the same stuff that you guys did? I need to up my vbios voltage right? Is there a moded file that I need for this? I am afraid to use the one that was posted back in 2011, because my vbios might be too new for it.

Could somebody please at least point me in the right direction? What all do I have to do? I figure all I need to do is flash my vbios to a 1V version. And then I can just overclock with any oc software? I also read earlier that I should use a certain overclocking program? Is that still true? Nibitor or something like that?

Anything else that I need to be aware of? Any other tweaks that have been discovered? I am not going to lie, I didn't read this entire thread because it's too long and I can't really decipher what all needs to be done on my specific model (G53SW). Some posters have g73 and some g53, so it's confusing to figure out specifically what I need. I think that Kingpinzero, has the same model as me.... so if you can hear me man.... please help me! I have a feeling that you could tell me exactly what to do. I am hoping to get my GPU up to at least 840.

 

I am fairly savvy. I think I can build the bootable USB drive and run the nvflash tool by myselfl. I don't need the details of how to do anything (i think).

I just need to know which vbios I should use? also what program to use to make any edits or tweaks to the bios? also what method to use to adjust the clocks? Should I use an application like nvidia inspector? or should I adjust permanently in the vbios(like mentioned earlier)? also, does anybody have any ideas for adjusting the latest drivers to increase performance? I have the latest NVIDIA drivers. I beleive they are 314.07.

also, when OCing, is it better to have my card in performance mode, or quality mode? or does this option behave the same whether OC'ed or not?

 

ok so I think I have read the majority of this thread now. I still really don't know what the final verdict is. Sounds like I might not want to use the 1V vbios mod because a driver released during 2012 really disagreed with it. I wonder if the current drivers that I have, will have this same problem? Also, I still don't trust that my G53SW is going to be compatible with the vbios mods that were posted way back in 2011. I bought my machine about a year ago.

 

Just because the mod allows up to 1V means you have to run at 1V. You'll also have the 0.96v option.

 

The 3d voltage will be set by the bios so you will have to use it, but it's worth a shot and it's easy to reverse....

 

Why can I not use nibitor to change the voltage? when i create a rom with nvflash i can´t change anything with nibitor.
I have a Asus G73JW (german) with a GTX460M. When I use MSIAfterburn i can overclock my gpu up to 810/1620/1450 ...but i want more *g*

 

Because nibitor does not support voltage changes IIRC on fermi products, they have to be manually modified.

 

and what can i do to modify the voltage manual? I have read something about a hexeditor in this thread, but i don´t know how can I use this.

 

Hi. I have question.
I was prepare bios for gtx460m by modifying 676F adress with new value 2. But I have doubts about this, that's all? No cheksum calculation needed?
Fermi bios editor for original show green light but for modified by XVI32 no, I didn't see that anyone write about chks calculation after change.

Regards
Greg

 

The reason we were using XVI32 to edit the vbios was because the early version of the NiBitor did not support voltage changing for the GTX460M vbios, what people do at that time is change the voltage using XVI32 and open the edited vbios with Nibitor then save it again using Nibitor then you will see the check turns green. And yes, that's all, the reason why we changed 01 to 02 was because the code 01 tells the chip to use 0.9125v for 3D clock zones and 02 tells the chip to use 0.962v for 3D clock zones and we wanted higher voltage than 0.9125v so we changed 01 to 02, code 02 for 0.962v is the highest voltage that's available inside the original Asus GTX460M vbios, so if you want higher voltage than 0.962v you are going to have to add the voltage tables manually. Now with the newer version of the Nibitor you can skip the XVI32 and use Nibitor to edit instead, well for the GTX460M.

 

Good chance that higher voltages may not work anyway of course.

 

hackness Thank You for explanation.
I have done unlock voltage, the card is stable to approx 800Mhz but I notice dramatically dropping of FPS !!!
I'back to stock voltages for now because there is no such problems, anyone has notice something similiar?

Regards

 

What are your temperatures at the higher voltage?

 

83-85 degree are maximum values I notice during stress.

 

Any chance of a picture of MSI afterburner or similar showing the throttle?

 

I have two screen from MSI Afterburner, first is with 765mhz core and 0.96V, second is with 800Mhz core with crysis 3. There are visible performance (or load) drops. Both are unplayable unles I set 0.91V, then is working fine. Why? This is not throttling, because at lower temps is the same situation. Sorry I don't know how to attach screens on forum.

Regards and thanks for interresting my problem

 

What does gpuz say under the sensors tab about the clocks? Are they going to 3d levels?

 

Yes, the frequency is entering in 3d levels. I think that is hardware problem, and that graphic card doesn't like to be overvoltaged

 

Some VRM chips have built in OCP protection which may be forcing the chip to skip cycles. It gets rather complex to modify the circuit providing that reference though so maybe a bit too much effort.

 

I was't notice that anybody here have something similar to me, You suggest that may be protection? Is any option to bypass this?
Regards

 

Hi guys, sorry for bumping this thread!

I was receiving so much driver stopped working errors on my g73sw then i decided to flash my vbios with the one that Saltius provided here. I was searching and i read that my gpu needed to get more voltage. I followed all the steps and flashed my gpu.. But now my screen is all black and i cant do anything. I got the windows sounds but the lcd wont work. I also have my original bios saved on the same pendrive that i used to flash my vbios. Any ideas how to change it back? Am i ed up?

Edit: uploaded the vbios that i used and my original one. I had to name it *.txt

Edit2 - I solved the problem using an extra monitor and flashing my old vbios again

So anyone can give me the right vbios for a g73sw 3DE - GTX 460m? Im getting so much errors and i need to overvolt. This one worked the voltage but the lcd fcks up.

Thanks!

 

Have you tried editing your existing bios using Nibitor?

 

Cuz i cant modify the voltage with nibitor. It doesnt read my gpu as gtx 460m
