Modified overvolting vbios of GTX460m on G73SW.

The difference being we have 2 profiles .95v and 1.15v the Nvidia has a third profile already set and they are just specifying the vbios to use that profile which gives a slightly higher voltage. We are already using the highest 1.15v and nearly everything has already been done to change that on our JH and to be honest I think the only route is a hardmod. The same thing happens if you try to specify your own voltage it will just revert to the nearest profile be that .95v or 1.15v.

The reason why you can overclock on the latest .93 vbios is because OD was not accessable on the earlier versions.

 

Anyone did some vantage runs? My friend just did some with his G73JW and the modded VBIOS:


clocks----------------------gpu--------cpu----------total

860/1720/1600-----------9117------14788 -------10048

875/1750/1608-----------9274------16314------- 10395

875/1750/1665-----------9349------16391------- 10474

 

Jesus 875 on core? Thats a record, i never saw an 460 going that higher!
Make him bench in 06 and 11!

 

Man this overvolting vbios does turn JW into a beast, now my stable OC is 870/1740/1625 and 3D mark 11 score raised from P2300 to P2524. I tried 880/1760/1625 but my GTX460M started throttling like 3min into the bench. So 870/1740/1625 is probably close to the highest setting for my GTX460M.

P.S.#1 Furmark 10min temp = 90C, a bit high lol.
P.S.#2 The vbios I used is the first vbios modified by Saltius. The LED screen is working fine.

 

Slightly off topic thought I would sneak this in here

What multi's are you running your 940XM at fella. cheers.

 

I was running it at 23x on 4 cores, I tried 24x before but there's once that my 180W power brick had its thermal shutdown so I only do 23x now lol.

 

That is interesting because I can run my 920XM at 28 on 1 core and 24 on 4 and I am using a 150watt stock adaptor without throttling.

Wonder if the JW sucks up more juice elsewhere then.

 

Yea I feel strange as well but perhaps that time the room temperature was a bit high and according to what they showed on notebookcheck.net, JW ate like 149W full load at stock setting (740QM|GTX460M) and JH had it around 145.2. I understand 740QM maybe use more energy than 720QM but it maybe possible for a JW to suck up more juice.

 

Ahhh to understand Asus and their laptops A myth in itself.

 

Finally i did some runs on 3dmark06 and 3dmark11, multiplier of 920xm is 24/24/24/24 and the gtx 460m runs with 880/1760/1665 core/shader/memory:

3dmark06: 17114 GPU: 7147/7242 CPU: 5369



3dmark11: P2591 GPU: 2337 CPU: 6531



maxTemps for Cpu were 94°C and for Gpu 75°C (roomtemp: 22°C)

Lets see if someone can beat my results ;D

 

See the post above

@NeoConker89: Awesome work!! Cheers!

 

My JW just received the VISA for the P2600 Blah blah nation ; P2601, Core 880/Mem 1600, 940XM 28/28/25/25 Temperature ended up at CPU 97C/96C/95C/97C and GPU 73C.

I mentioned before that my GTX460M throttles when I pushed my core to 880 (VBios 70.06.0C.00.08), but then when I saw the hex picture that Saltius uploaded I decided to try and modify a different VBios (SW VBios obtained from lpnowlan, VBios 70.06.25.00.07) using XVI32 and then modify the sub-system ID using Nibitor, sucessfully modded, voltage is also on 0.962. After flashing and testing I found that my GTX460M no longer throttles at Core 880/Mem 1600 . I tried going for 881 or 890 on core but anything after 880 would just give artifacts or just crashes. The default clock 900 in the picture is just for testing.

 

I've done another 3 runs on 3dmark11 with 895/1790/1665 core/shader/memory and 27/26/25/24:
p2627 Gpu: 2370 Cpu: 6584


In 3dmark06 the 285.27 beta driver stops working during the last benchmarktest.

In dx11 games I can run the card stable on 860/1720/1665 and for dx10 games 870/1740/1665. No more problems with Crysis 2 and Mafia II on 1920x1200 display.

 

That's awesome guys! I really envy those clocks
The best I could do without freezing is 825/1650/1650, while 830/1660/1650 is stable only when benching otherwise it glitches.
Now I'm aware that probably I have a binned gpu, the overvolt surely help alot.
I can test however 850/1700/1500 to see if lowering VRAM clocks helps core oc, as both doesn't like very much each other!

 

this is really interesting... i'll have to try in mine, see how high this thing can get...

 

Thanks! OFC ... im really bad becouse my Asus cant o/c more
Hmm ... hardmod ? you have in mind - include in to hardware?
Im newbie in this - and in Poland "new" G73JH its worth like 2-3 Job Payment-then if i will broke something i go shoot myself.
Thanks again - maybe i will have more luck in AlienWare in next 3-4-5 years and when i get 18's years (december) - then in 20-21 years i will buy alienware or clevo (sager)

 

haha yeah dont even consider a hard mod and as you say I am in the same boat I cannot afford the top tech my JH is my baby and if it broke - Game over.

I am just going to wait for the M17x R2 to drop in price and then pick up one with 2* 5870M for cheap, I still love this card I think it performs very well even at stock clocks and 2 can hit 20k in 3Dmark06 with an 920XM - yes please

 

How do you edit the vbios on the G73SW to overvoltage it? Can anyone help?

 

For JW vbios, change that one to 02.

 

And this one is for SW, both 53SW and 73SW are at the same position. Change it at row 6765 from 01 to 02 like Saltius mentioned before.

 

Sorry, but how do I obtain my vbios from my laptop? Using a g73sw. Please help.

 

You need to dump it using a bootable USB drive and nvflash.
There are a few guides around, google for "dump VGA vbios using nvflash".

 

@rezegen, you can take it with nvflash but it will not work with 64bit so you need usb stick which you will make it bootable " hpformat tool " and win98boot files and what you need ?
first make a bootable usb with Hpformat tool just install and at the start up check dos box 2nd one I think and browse win98boot files too then wait for the format progress so now you have bootable usb and later copy nvflash files to the usb drive 2 exe files and 1 doc file for the command.

in order to get bios you should boot your computer with usb so from bios as you well know F2 will direct you there, you can change boot order to usb so when you restrart computer will try to boot over usb and mostly driver letter will be C again so final step

C:nvflash -b 1.rom will be your command and it will save your original bios into the usb as 1.rom so you can keep it for future if in case.

if you update your old bios with new one which has been given here first save it into usb drive and give it a new name as 2.rom this will be modified one " 0.962V " and boot your computer with usb again .
new command C:nvflash -5 -6 2.rom and when asked just type Y then wait, drive letter can be different just for info

it can be black screen issue " actually I didnt faced " but seems it be solved also by external screen if in case.



so,,, 875/1750/1550 is working fine if increase the memory more than 1550 it is not stable sometimes even crush but for real game play 865/1730/1600 seems max for me , on the other hand 880 core after 1 min crush also but maybe reducing memory can cover it,
there is one reality case has been solved in really great care so what next

 

It's probably better for himself to mod his own vbios, since the hex address for G73JW is different to G53SW and again G53SW is different to G73SW, and Saltius only provided the vbios for G73JW and G53SW. The process of modding is really easy for SW, download xvi32 and open the vbios with it, navigate to row 6765 and target 01 (which is Adr. hex: 676F!) in that row, change it to 02, save and done!

 

Actually I used same bios which is given on the forum nevertheless with given xvi32 I couldnt see any row as 6765 or 676F! that s why I just used the bios on the forum so it worked I m not sure for the gaming performance increasing because it seems so similar " 0.962 V for sure " benchmark Heaven and 3DMark11 also inreasing but not a huge jump for 865 core clock so 865 core stable but why we cant gain much more or maybe personnally I was expecting much more so great improvement on 875 core it is completely acting different but not memory should be adjusted even maybe till 1500 if you can keep stable 875 core with 1550 memory, just fly

 

I checked both bios almost row by row almost totaly different but works I have similar row data on 674D "0F 04 01 18 " / 676F but when you re-open program address changing 674D/674D so I will also make a try for this and I will check once again like that so let s see the result

 

I have a stable OC for benchmarks, which is 850/1700/1500, same problem as me, if i raise Mem Clock it crashes and i cant raise Core Clock.

So the trick is to find a sweet spot to have both core and memory overclocked without crashing.

So my Gaming Clocks for now is 840/1680/1600 which is stable 1 hour into Shift 2 Unleashed maxed out (no AA) with an average of 65fps lol.

 

Now my stable gaming clock is 840/1680/1700. Most games I play have no stuttering porblem now

 

Hello my friends!
I want to congratulate you all for Creativity! With this new VBIOS modified to 0.962 V, I can get a stable 850MHz on the GPU without any problem on the screen or the Temperature Range.

I did heavy testing with FurMark, and the results were Excellent, about two hours of tests without problems at 850MHz on the GPU.

Only I have a annoying problem and still could not find the cause, is that since I went from my 800mhz GPU to play games like Mafia 2 (Especially when car enters encyclopedia) After a few seconds (about 40), my notebook turns off completely.

This has also happened Playing Crysis 2.
This all happens when you step on the GPU 800Mhz.

Remembering that this never happened with FurMark and not with other titles.
I'm starting to think and some flaws in my OS, or some frequency that is causing interference on the motherboard.

Would there be the possibility of someone from here by using the MAFIA 2 and test?
just get in the car encyclopedia Mafia 2, and wait, to see if it will shutdown occurs.

Someone also would be interesting to clock above 810Mhz GPU for doing this test also.

Post the results.

Thank you for your attention! hopefully I managed to figure out WHAT is causing it.

---------------------------------------------

 

Furmark actually means nothing to stability test for gaming. I know myself when playing Crysis 2 if I go over core 845MHz with V0.962, it will lead to a sudden shutdown within 10min - 4 hours, I think it's the voltage that's doing it. When it was running at V0.9125 it turns off itself around 800MHz within 10min - 1hr when playing Crysis 2. You may have reached the maximum stable clock including the CPU usage at core 800MHz maykon_helver. Running Furmark doesn't mean anything on stability test because it is not really using CPU like other games do.

 

Thanks for the reply.

It's good to know that other people face the same problem.

I still do not think that is the GPU clock limit, I think I should be any limitations on the use of chains for the MXM card.
or else some electromagnetic interference generated by the higher GPU clock.

If so, I might even try to make a bridge connecting the video card directly on the power supply.

Anyone know inform the wiring diagram of the circuit MXM?
ie What is the Input Voltage pin and in which I would connect.

I know this can be risky, the more hope is the last to die! (or my video card dies kkkkkk)


tanks.

 

Not worth the increase in power, high risk of failure and best case scenario you fry the card - worse you fry the board.

Enjoy the overclocks you have achieved frying it wont achieve you much.

 

Hey guys, I have successfully overvoltaged to 0.962V!
I do have one question though, whenever I looked at nvidia inspector the voltage says its 0.812 when its idle...do the voltages downclock when not in use???

 

Yep they do as the lower clock state uses 0.812v for power saving.

 

@Saltius/// it seems that somebody already trying 1.0 V for GTX 460 M and it can be really tried but in this point I would like to ask something for the voltage level, somewhere in this forum you were saying 3 different voltage level but in the hexedit side which line you could see this values, actually I have already tried to overwrite with hexwrite to increase V level maybe the line which you observed can be modified I m still working on it for over 0.962

in 0.962 more than 865 core not so stable can run but cant be given guarantee how long

 

MSI and Clevo version GTX460M have 4 voltage settings with 1.0v the highest one. Alienware version also has 4 setting with 0.95v the highest.

I've done the mod for those cards' vbios with success.

However, Asus version GTX460M only has 3 volt settings.
I think its PWM should also support 4 level voltages like MSI/Clevo/AW ones.

Things get more complicated that this time I need to deal with the voltage table other than just to tweak setting 01 to 02 like before.

Anyway, I will try and get a modifying vbios for the one left voltage. Just wait for a moment.

 

@Kingpinzero

I just modified a new vbios.
Do you like to make a test?

It is only for 460m on G53SW.

For safety, I will not provide 1v overvolt vbios for other ASUS 460M until your result comes out.

 

Perfect Saltius, I'll test it as soon as I go back home in a few hours and report back.

 

Hello friend, congratulations for the excellent work,
not tested this yet 1Volt VBIOS to soon put the result here.

Either way, do not anticipate we will have more than 1Volt of tension in the GPU, if we can not Supluir the largest potential energy of MXM Card.

I opened a forum here for us finding a solution to this.

http://forum.notebookreview.com/asu...safety-shutdown-forced-possible-solution.html

that is, if we want to really use all the power Overclocking GTX460m, we must be able to deliver all Nescessaria Energy.

 

Ok flashed, first results are in (im benchmarking as we speak):

broken my previous record under 3dmark11; also i bumped the clocks to 850/1700/1600 and completed succesfully a run.

NVIDIA GeForce GTX 460M video card benchmark result - Intel Core i7-2630QM Processor,ASUSTeK Computer Inc. G53SW score: P2474 3DMarks

im about to test it in 3dmark06 and then in some games.
But for now seems that 1.0v indeed works. Ill report back in a few minutes.

 

Ok 3dmark06 reporting:

16,319, another personal record broken.

Im going to test these clocks in a game like Deus Ex who made my precedent OC unstable.
BRB.

 

Ok im still not stable at benchmark clocks, but im stable in games with 840/1680/1600, probably i can raise even 50mhz more on ram, but i didnt tested it deeply.

But so far when it was supposed to crash in deus ex it doesnt now.
Ill do some more tests.

 

What voltage does GPU-Z or NV inspector read?

 

V1.0, just logged a gaming session to be sure.
Also it seems that I can stay above 10mins in DeusEx at 840/1680/1650, it crashed but when I got back to desktop the gpu hasn't crashed since I had same clocks as before.
I suppose the game crashed itself.
Probably tonight I'll do another 3dmark06 run to further confirm my benchmark clocks and update the sig, I've added only the 11 score as for now.
But I confirm it works and it's more stable, and keep in mind that mine is a binned gpu, I can't go anywhere above 840 stable.
I can do 850/1700/1600 now but just for the time of a benchmark run.

 

Well, it makes sense then. As some Clevo/MSI 460m users reported to me that they got stable at 840~850MHz with 1.0v vbios while 810MHz~820MHz stable with 0.95v stock.

 

Hello my friend, congratulations for the new achievement.

Take a look at this topic, http://forum.notebookreview.com/asu...safety-shutdown-forced-possible-solution.html
and perform the same test I did with MAFIA2
I think you will have the same problem with this shutdown Overclocking.

 

Saltius, congratulations again! you're a genius!

I'm waiting for the MOD Asus G73JW 1Volt VBIOS, I'll try here too!

thanks

 

AFAIK, M15x suffers that issue as well. Not sure whether those AW guys ever figure out some solutions or not.

 

Maykon I forgot to tell you that I'm stable under mafia II car encyclopedia and benchmark.
Never had a shutdown issue with the game, I've unistalled it but I can reinstall it for you.
Btw don't forget that our laptops are different, you're still on first gen core i7 while I'm on sandy bridge, it's a different architecture/thermal design and so on.
I'm still topping 84c max on gpu althought I'm on v1.0 now.
And Saltius, thanks
DeusEx is still a b1tch game to run, stutter and jittering happens from time to time and performance isn't stellar at all, but still it pushes the gpu much like Crysis 2, it's a very heavy game.

 

Wait, no change about temp? I get a little suspicious then....
Can you try this mod vbios as well?

Besides, is there anyone who can tell me the PWM chip that ASUS GTX460m uses?

Edit: Update the 2nd 1v mod vbios.
