Modified overvolting vbios of GTX460m on G73SW.

G73JW stock vbios: View attachment GTX460M.zip

 

wow fast, thanks, i will save it now.

 

My ASUS G53SW-XN1 can't boot because of this error message "Invalid System Disk" ... "Please replace the disk and press any key"!
Any solution, anybody? :cry:
By the way, any kind person please share with me your "ideal" modded vbios!
Or can you please mod my original bios?
Thank you!

 

See if you don't have any disc in the DVD drive.
Are you using an hdd or Ssd?

 

Thank you, hackness!
By the way, how much we gain after overclocking GTX 460M? For example, my average fps in high settings for GTA 4 is 27 (although it drops to 8 sometimes), will it reach 30 or more?
Is it risky if I try the G53SW 1v Test of Saltius?

 

0.9125v > 0.962v, should allow you another 50~80MHz boost on core clock.

OK, here is another problem!
I boot successfully, but when I type the command "nvflash -5 -6 -A (my bios name).rom, I get this error message:
ERROR: No NVIDIA display adapters found
What does it mean, guys? Any solution for this?
Thanks in advance!

 

Did you try nvflash --list and see if nvflash sees your card?

 

The reason it drops to 8 sometimes is because your CPU is throttling, download ThrottleStop 4.10 or 5.00 and disable "BD PROCHOT" and it should stop throttling. And yes it should reach 30+ with the clock you can reach at that voltage.

If you own a G53SW, you can try Saltius 1v vbios, if it doesn't go through the check you can still do nvflash -4 -5 -6 Name.rom. It shouldn't be a problem if sucessfully flashed.

 

Thanks again hackness!
I really appreciate your help and quick response!
I think I get the error message because nvflash 5.77 doesn't work with my system. I use older version like 5.10 and it works!
One more question though; is there any way to modify the default clock so that after flashing vbios it looks like this:
GUIDE for Flashing BIOS of NVIDIA GPU - techPowerUp! Forums

 

Yes it's possible, but Fermi GPU is slightly different to the 200 series showed in the guide, for Fermi GPUs you need to modify it using Fermi clock in the Nibitor software that's later than 6.04, right now the latest that's open to public is 6.06.

 

OK! Nvflash was successful!
And now... Silly question though, what am I going to do after flashing my VBIOS?
Or what steps do I have to do next?
I really appreciate if you guys can teach me step-by-step!
Thank you!

 

The easiest way is to download MSI afterburner and overclock using that. At the 0.962V the typical core clock that's allowed to go up to is ranging from 840MHz~870MHz. However 1v doesn't really allow the clock to reach a higher zone.

 

Hi all, Ive been running my g53jw at .962v for a while now and all seems to be going well, in BF3 I can only really get up to 810 before crashes, and strangly, when the shaders are at odd tens i get very poor frame rates... 3-7ish (as in 1610 or 1630 shaders will give me 3fps.. and 1620 or 1600 will give me 42ish..) Id like to try out a 1v vbios as hackness mentioned in this post:

That he was able to get his 73jw up to 860, he later posted a vbios of 870mhz which i had a look at in nihibitor and some of the values seemed very high, but it did have the 1v voltage, i changed the clocks in nihibitor to his reccomendations in his prior post, but when i flashed that through, the laptops screen didnt work.. using an old external monitor by the vga cable i was able to restore the previous vbios, but before that i curiously let it boot to the desktop where it had a crash/driver restore with no programs running... so i went back to the .962 vbios...
So with this, is it possible to get 1v in g53jw as others [apparently] are in 73's and sw's?

 

If the GPU in G53SW is the same as G53JW then the video out might be slightly different to G73JW/SW. What Kingpinzero did was to reassign the display in windows via external display. By the way, every card is different so if you get sudden shutdown or driver crash at lower clock then you are likely stuck on that clock.

Forgot to mention that the 870MHz on core doesn't shutdown on mine but it does throttle the clock after a while, so the maximum stable core clock on my G73JW's 460M is 860MHz at both 0.962v and 1v.

 

Hi guys,
I have G53SW with 460M and it is somewhat problematic.

Once in a while it does BSOD, usually when I leave it running (doing nothing) overnight with the lid closed. The easiest way for it to crash is to start Firefox. It would usually go through several TDRs and eventually BSOD.

So, a while ago I got a replacement 460M on eBay. Disassembled the whole thing, replaced the card.
BSODs again. Whiskey Tango Foxtrot.

On top of that, I cannot even install any newer driver. No matter what I try after driver 268 it does not install (both on old and new card). The installer crashes and then the install of the kernel driver seems to fail and Windows switches to VGA save 800x600. I tried installing from inf, same thing, KMD (.sys) doesn't work. I tried whole bunch of drivers from nVidia website and drivers from ASUS site. None of then after 268 work.

So I am getting desperate. Somebody who had problems with the card in this forum mentioned that the GPU may be getting wonky in super low power states when the voltage is set to very low. So is it possible to change the VBIOS to increase voltages across the board including the low power state?

And how is VBIOS flashed? I tried MMTool and there is VBIOS embedded in the main BIOS as option ROM. So how can the video card flasher change it?

Is it possible to install Radeon Mobility HD 5870 in G53SW? Would it work? Does it have BIOS on the GPU board too? Maybe instead of fighting with 460M is could replace it with 5870 (which I would actually prefer).

I looked at G73JH Main BIOS and it has 5870 Option ROM embedded in it. But it is 128K and it seems impossible to insert it in G53SW main BIOS.

So how does flashing the VBIOS work on our laptops, because it seems the VBIOS is part of main BIOS?

 

Can you go to device manager look for the hardware ID of your card and post it here? Sometimes the card hardware ID that's later made isn't included in the NVIDIA driver, so we'll need to mod the driver.

 

The hardware IDs are already in the driver inf in both nVidia drivers and drivers from ASUS website that I have tried, I checked and there is no need to mod them. Setup or inf install detects the card and proceeds to install the driver, it is just that the KMD does not initialize.

BTW, I have 16GB of RAM, if it makes any difference.

 

I see, currently on my old G73JW, 304.79 is installed. When you get the BSOD, does it mention anything related to nvlddmkm.sys? If not then it might be something else. Also you can try to test your RAM, run them one by one and see if any of them don't give you the BSOD issue.

 

So today I put in a new SSD and tried test Win7 64 reinstall on it and the 301.42 driver installed fine. So I am in the process of reinstalling everything from scratch again and the latest nVidia driver works. Hopefully the driver will resolve my BSODs.

We'll see soon ;-)

 

I just wanted to second the report that trying to update NVIDIA drivers above 301.42 on an overvolted 460m causes a lot of crashes. New WHQL drivers just came out and I was excited because all previous betas crashed my system; but they caused system hangs, reboots, and BSODs as well. Reread this entire thread and re-flashed back to my original vBIOS posted earlier and the latest 306.23 drivers installed perfectly and have been rock stable. Thanks DeadBeef.

 

Hi, have you noticed much improvement in performance or overclock ability to 306.23? I'm using the 304.79 driver and modded vbios on my g53sw right now. The update log on nvidia only mentioned improvements for the newer 5xx and 6xx series so i'm wondering if its worth the trouble to do a clean install of the new driver.

 

Well, I had been running stable at 825/1500 with the modded vBIOS on 301.42. Now with 306.23 It's not stable over 790 or so but I can't say if that's the new drivers or going back to stock vBIOS that's causing it. Tried flashing modded vBios again with 306.23 installed but immediately froze the system.

 

Hmm, probably the vbios than, i'm running at 830/1500 stable right now with the vbios. The newer drivers probably wont benefit us much since the 460m is relatively old now.

 

Hi, i have a g53sw using the modded vbios with 0.97V and i have stable overclock at 830/1660/1500. Do you mean that the stock voltage actually gives a better overclock? Last time i tried with 0.9125 overclocking i usually crashed at around 800 core clock though, but thats almost a year ago.

 

No I mean the change in that vbios is that the voltage is upped from 0.9125v to 0.962v.

Actually it seems like after the driver is updated to 302 or later, the voltage is displayed as 0.92/0.97 instead of 0.9125/0.962, and very rarely some cards can go to core 830 with 0.9125v, a lot of them couldn't get past core 800, 0.962 allows them to reach 840 or higher.

 

Guess i have one of the not so good gpus, running into artifacts over 830 mhz core and 1500 mhz memory.

 

Hi guys. I have a G73jW, can't go over 794mhz, it crashes. I would like to flash my bio with bios that has higher voltage data. Can someone provide me with vbios and quick how to flash? Thank you, I was reading the topic, but too much foreign language for me to be 100% safe what to do.

 

Help, please? Cheers.

 

Ok, I just need the G73jW bios with 0.962 voltage. Please? Cheers, gonna flash it it's simple.

 

So, when I put the G73jw 1V mod, the screen goes blue and driver crashes.
On G52jw vbios I get 0.962V but no HDMI, so that doesn't work for me.
When I want to edit my vbios in HEX32 what values do I change? I saw a screenshot where the section CCCC should be modded from 01 to 02, but I don't have CCCC section? HELP? Thanks guys!

 

If someone can change my voltage to 0.962 on my bios? Thanks.

 

There you go.

Thanks matey. I will test it right away and post how it's going!

 

OK, ran 3x MAFIA 2 benchmark, 1920res, w/out phsyx, medium detail, 57fps, 820Mhz/1500 mem
Could you bother modding my bios for 1V voltage? What would be the approx maxes for my card on 0.962 or 1V? The mem is to the max, as afterburner has only 1500MHz top? Oh, the temp of the GPU was around 82-84 while benching MAFIA 2. Is that ok? Cheers guys, especially hackness.

 

82-84C is ok. By the way I don't know how to populate new voltage table, 0.962v was originally there but ASUS choosed 0.9125 instead, all I did was redirect P15 to use the 2nd setting, you might have to ask Saltius for 1v modding.

 

Oh, thanks matey, will wait for Saltius to mod my bios for 1V.
As things stand, the Bench, driver restarts at 830. Will see what are the maxes. Is 1500 mem ok for the 0.962?

 

How can I push memory over 1500? I think that could help some more! Please?

 

MAFIA 2 bench, at 825/1500 mem all good. Temp of the gpu is 85 under load.

 

OK Installed the latest MSI Afterburner, running 825/1600 stable. 85C temp.

 

eventually, laptop goes to sleep while playing Mafia 2 on 820/1590. Vram getting hot?

 

Sorry was on the plane.

Your card has probably reached the maximum TDP that the MXM slot in your laptop motherboard can supply. I believed yours is rated as 75W, you can go beyond that but this is all luck when it's close to the 100W mark. And if this is the case, a larger power supply won't help (I've tried)

By the way I wouldn't overclock the memory as the scale in temperature increasement is pretty large with the GTX460M and only very little gain is achieved on the memory bandwidth side due to the low amount of cuda cores.

 

Thanks for the reply matey, I reckon'd that. Running very stable at 820gpu/1580 mem, so I'm pretty much satisfied. That's a huge step with 0.962 vbios considering, I had crashes before at 791/1500, so the limit was 790/1480.

Still have try 1V mod, I just hope Saltius still gets around in this thread and mods my vbios.

 

Tonight I have installed Radeon 5870 from G73JH in my G53SW. Mechanically it was a bit of a challenge - I had to dremel a bit of a screen hinge to make the heat pipe fit. Unfortunately the laptop didnt start with 5870, it was just blinking the power light. I think it is because of missing BIOS.
I tried to add or replace VGA BIOS in main bios image file but the tool I was using didn't want to do it, I could replace NV BIOS image, but I couldnt add additional BIOS or replace 64KB NV BIOS image with ATI 128KB image.
So I think if the BIOS can be modded maybe 5870 will work in G53.

 

I'm thinking about getting GTX5xx/6xx in my G73jw? Is it possible? Where could I buy the graphics card or the gpu for it?
Is it even doable? Because it's a bit of a challenge pushing poor little GTX460m to the limit. How strong card is it anyway. Not impressed tbh, Mafia runs sometimes nice, sometimes I experiance sudden slowdowns, and I hate that tbh. Still gotta try 1V vbios, but temps on my gpu are getting to 85-86C and who knows how hot memory on the gpu is, and when mem is anywhere above 1550 laptop goes to sleep mode while playing games after some time.

 

svl7 made a nice guide here for the G73JW users:

[Guide] G73JW - upgrade with Nvidia GTX 660m

He's using the GTX660M provided by MXMupgrade.

 

Nice one! I sent them email regarding the card. You think it's too much hassle to install it by myself? Only thing that worries me is the modification of the heatsink. I dont see the pics, cause I'm not registred user.

 

Seems to me that Mafia 2 doesn't like overclocked memory on the vga. Just pushes the pc to sleep mode after few mins of playing.
Deffo need Saltius to mod my bios to 1V ad see if I can push gpu core rather than memory.

 

You'll need to purchase a G73JH's heatsink and grind down the x-clamp's screw holes area so the heatsink can attach the die area properly, grinding is pretty much the hardest work you'll face in this upgrade process.

 

Here is some weird stuff. So, the laptop does 57fps on Mafia 2 benchmark, standard cpu clock, 820Mhz/1550Mhz mem.
With the bus speed increased, and overclocked CPU, I barely get 44-45fps. When I reduce the bus speed on the cpu from 133Mhz to 130Mhz, I get 59-60fps average in Mafia 2 bench. How is that possible? That with the lower cpu speed than standard I get better results?

On the other side, laptop goes to sleep mode when GPU reaches 86C.
Yesterday I dusted the thing with air duster, and have approx. 80C on the GPU under the load. NOW THE INTERESTING BIT: since I don't carry much my G73 around, it stands at home with HDMI attached to my LED TV, I didn't put back the cover of the mem and HDD. GPU is now at around 76-78C without the cover, overclocked and under the full load! Really nice result, it was abit dusty, but cover deffo keeps the heat in the laptop, so I'm better without it when it's at home. TRY IT. Looking for nice laptop cooler to put under it, waiting for Saltius to overvolt my vbios to 1V(hope he comes arooound soon), so I can OC the out of the thing. It's an amazing laptop deffo worth the money I payed for it, it just need alot of attention and searching about it. :thumbsup:
