video bios Asus G73jw - maximum overclock GTX460m

Hello Friends, I apologize if I'm inflicting any rule, is the first time I open a topic here.
I am here to find out why some users get the overclocking GTX460m stable at 850MHz, and others (like me) can not stay stable Above 805Mhz GPU.

Using AIDA64 Extreme, I noticed that the secret may lie in the voltage of the GPU. Let me explain ...
The maximum 3D GPU voltage is 0.912 Volts
however, I noticed that when you start the test with Furmark The voltage on the GPU was at 0.962 VOLTS, then after a few seconds the voltage fell to 0.912 Volts.

My Current Clock is 800Mhz and is stable!
By using 850Mhz clock is stable only for a few seconds, after which the video card restarts.

I concluded that the GPU at 850Mhz restart when the core voltage drops from 0.962 volts to 0.912 Volts.

Now comes the question.
Because some users can stay stable at 850MHz on the GPU?

Answer:
My theory is that there are difference in the Video BIOS.
I think in some form, who can stay with 850Mhz clock in the GPU voltage is not below 0.962 Volts. That makes him Stable

After researching, I saw that our VIDEO BIOS has two versions.
Version 70.06.0c.00.05, and Versions for 70.06.0c.00.08

My VBIOS is 70.06.0c.00.08
Would the people who stay with the Stable at 850MHz GPU uses the VBIOS Version 70.06.0c.00.05 ?

Anyway, if anyone here is using GTX460m Stable at 850MHz. Save the VBIOS and Post here to be able to Download.
I think this is the Secret. to save your VBIOS, use NVFLASH.

I am sending in Annex screen shots that show the difference in the voltage.
Thanks for the Warning! I really want to be stable at 850MHz.

 

I'm pretty sure it's not because of the vbios but because of the die... if you're lucky you can overclock the card higher, if not... bad luck. The chips are designed to work stable at their default clocks. Everything else can be seen as a "bonus".

Higher voltage can ideed lead to better overclockability, but I really doubt that there are two vbios around with different voltage settings.

 

I do not know!
I can only make sure, after I use the VBIOS for somebody who can run the Stable Furmark to 850Mhz.

Thanks for the Warning!

 

Guess there is 3 different vbios'. Here is a SS of my GPUz, I can run stable at 850mhz, though I havent done extensive testing on it.



Here's my vbios as well,

800 -> 850 OC yields P2133 -> P2244 3dmark11 score on G73SW. Nice find. I have the 70.06.25.00.07 vBIOS.

 

Thank you for your attention! Information is Appearing =)

But I can not use your VBIOS,
NiBtor informs the Red Light.

You could extract it using the NVFLASH? is very simple!

I think this is the BIOS that allows G73JW Staying at 850Mhz Stable!

You're an Expert User. =).

VBIOS 70.06.25.00.07

Uploads Your VBIOS, and posts here


Thanks

 

Heres the vbios from nvflash,

G53JW here with 70.06.0E.00.12 doesn't like 850.

 

Hello everyone!
I tried to use the VBIOS G73SW, I had no success
the VBIOS g73sW worked, But still I can not stay stable in Clock Greater than 800MHz.

ie, the voltage still too low to sustain higher than 800mhz Clocks.

I changed my tactics. The knack is to arrange one way to use a modified VBIOS.

Today I remembered that the GTS450 Video card, uses the same GPU (GF106)

So I took a VBIOS Original GTS450.
I changed the ID to Be theoretically compatible with ASUS GTX460m.
I changed the voltage and clock to get the level of our Video Card.

After you modify and save the VBIOS using NiBtor
NiBtor. Informs that a VBIOS Validates. (light green).

Not yet tested the VBIOS, in my GTX460m.
Now I need someone with knowledge VBIOS check and tell me if everything is ok.

I am offering it for Dowbload.
remember to have a backup of your bioses in a PenDivre.

V-BIOS MOD DOWNLOAD
attention, this is a VBIOS Desktop.
No one has guaranteed it works in GTX460m
Zippyshare.com - BIOSMOD.rom
Today I tested, not worked = (

one thing I forgot to mention ...
the tension has 3D in 0.982 Volts
That is, in theory, if Running in GTX460m, we passed the mark of 880MHz in our video card

 

So you want someone else to test your FrankenBIOS before you do?

 

hehehehehe! This was Funny!
I think I'll rename it to "FrankenBIOS" kkkkkk

More is not what I said no.
I said this, I wanted someone experienced here from the forum, check if the BIOS was to GTX460m Validates.

I found one other thing too. the VBIOS SAGER Notebook With the plate GTX460m
It has a voltage of 0.952 Volts according to the owners.
That is, has more than 0.042 volts Asus Our VBIOS.
Would be more right, take the VBIOS of SAGER and just modify the ID to ASUS? You think these 0.042 volts more, it make a difference to a greater Overlock GTX?
you think I would have more chances to work than use the "FrankenBIOS?

tanks.

 

How can i flash my gpu with your vbios ?

 

Look, his vbios is originally a desktop vbios. The chip is the same architecture, the hardware is probably quite a bit different.

It may work if you're very lucky, but most definitely it won't. And you risk killing your card irrevocably.

The idea is interesting imo, but it's also pretty stupid imo, nevertheless I'd like to see it to be honest

The clocks are pretty high, I'd lower them a bit before doing this, also I'd make entry 3 and 11 the same value in the P15 domain (3d clocks).
Also the voltage will be raised to 0.9875V, no idea whether your card can handle this, probaly yes... but like I said, the rest of the vbios is what's really risky, the hardware of the desktop card has probably some big differences.

Since you don't know how to flash the vbios it's probably not the best idea, but if you promise not to come crying when you kill your card I can write you a little guide. Somehow I'd like to see whether this works...

 

hum ok but im not crazy and i will not try his desktop vbios on my gpu ! I want to try the vbios of a G73SW to see if my O/C potential would be higher!
Because now i cant exceed 800MHz on the GPU and i would like to be at 850MHz ! ! (Tu parle français slv7 ?)

 

you have 80% chance to brick your laptop ( tu as 80% de chance de peter ton laptop, laisse tomber)

 

thx for french
But look at the first page, chasty have tried and it worked !

 

Non, il a pas essayé ce bios c'est un bios de 460M normal qu'il a try, celui que tu veux essayer est celui d'une GTS450 De desktop sur ta 460M ce qui est très risqué

 

Non je veux pas celui d'une GTS450, je veux celui d'un G73SW !!! Moi j'ai un G73JW et j'arrive pas à dépasser 800MHz donc je veux essayer d'atteindre 850MHz !

 

Translation for all the non-French speaking people here

No, she hasn't tried that BIOS, what she tried was a vbios of a normal 460m. The one you want to try comes from a GTS450 desktop card, which is very risky on your 460m.

No, I don't want the GTS450m vbios, I want to try one from the G73SW!!! I have a G73JW and I can't get past 800MHz but I wanna try getting to 850MHz.

 

Overcocked my card today. Have some interesting findings.

1) Got 850/1700/1625 stable. Did 8 mins of Furmark at 1920x1080 and Xtreme Burning checkbox chacked. That's enough, right?
The temp did no go past 89°C. Screenshot

855 on the core would crash the driver. No artifacting though.
1625 was the maximum memory frequency allowed by MSI Afterburner. Anyone know how to get past that limit? Are there other OC software with higher limits?


2) Seems like I have VBIOS 70.06.25.00. 0C

 

i think it's all luck that you can go over 800Mhz, not alot of people can go over it either.

 

Use the NVIDIA Inspector, Luke.

 

I'll upload a pic of my GPU OC in the morning(when the sun is up). I'm not using the G73 right now but my clock speed can be found in my sig. I have tested it with FurMark for 5 minutes and my temps only reached 84 C.

 

Courage Today I created, and effect change in my VBIOS GTX460m for VBIOS GTS450.

As many imagine, not worked.
Glad I had a backup, and restored my original VBIOS No problems in self executable Flash Mode.

I talked with a specialist VBIOS He explained to me that not GTX460m has no option in the Control Voltage VBIOS
ie, the core voltage is established by that manufacturer. and can not be changed by the VBIOS GTX460m

It makes me think of another explanation;
I think the Model GTX460m G73SW must have an operating voltage a little higher, maybe 0,962 volts. That explains it to reach the 850Mhz.

Up to this moment
Everybody who has come to 850Mhz Stable propietarios be informed of the Model G73SW.

I have no other explanation.

Someone who has the G73SW Could Confirm Tension in 3D using Aida64

 

Here's my screenshot.

well i ran an over clocking utility.. this is what i got.



any thing else i need to do to test this.. I havent ran any bench mark but..what should i use.

 

Furmark for 10-15min

 

Hey all, ..on the sensor tab of the GPU-Z it says like VDDC .8120 (min.), .9120 (max).

I've OC my 460M to 775 core clock proportion to memory and it yield 2231 on 3DMark11 (Performance 720p). At 800 core clock it scored 2287.. Tried both setting on Witcher 2 seem okay. CPU is stock. Haven't tried 850 core clock yet. One guy here has 820 core clock I think, playing TW2.

 

12414 3DMarks is the score i got with the oc i did. posted above.

basic test was ran 3 times in a row.. this is the last score.. and msi after burner said my max temp was 70c also it picked my default resolution..

ps im on a Asus G73JW-XA1

 

memory 1700?wow.. mine can only handle 1500-1550

 

well i was going to run setfsb but the free versions dont let you set it. so i dled a keygen that was a virus lol so now im left restoring my laptop.. lol i know its what i get! but hey i did find one free full version setfsb once.. but any who.. when i find setfsb full for free or a key ill post my scores once my cpu is over clocked also.. ive hear 14000 isnt unheard of.. and higher.. so we shall see..

now any advice?

 

Hey guys, I did another 3DMark11 benchmark this morning. GTX 460M 1.5 Gb. (192-bit) clocked now at 820/1640/1395 (core/shader/mem.) Stock CPU.

My result was: 3DMark11 (P2345) once only.

Even Witcher 2 at medium-ish at 1920x1080p open fights are averaging 32-34 FPS. Running at environment are at 32-40 FPS, cave fights are like 35-38 FPS. I wish I OCed before I finished TW2 the first time

It seemed like the GTX 460M could handle Ocing.. 850 core seem very plausible.

What do you think a stock AMD 6970M score at 3DMark11 with same CPU? ..P3000 points?

 

Yes, just about P3000 stock. I have a screenshot somewhere with 6970m/920xm stock in case you need to see it.

 

ok im confused.. how the ? do you guys get higher stock results than i do over clocked?

over clock gtx460m 850/1700/1480 i only got 2100 or so in the 3D mark 11

 

The driver plays a big difference. Between 270 and 275 whql, at stock core clock the newer one added 100 points on benchmarking.

My other result at 777/1554/1354 scored P2231. ..you have (192-bit)?

 

yes im at 192 bit.. maybe memory speeds are to high? for me? well im confused.. also your cpu is a tad bit better than mine so that might be it.

 

I've tried to flash my GPU with a G73Sw vbios but it said to me that the ids subvendors are different !! Whats the problem ?

 

But why people with ATI HD5870M can change there voltage ?!

 

Not on the G73JH we can't it is hardwired the same as the 460MGTX.

 

Oh ok thanks

 

That's not a big deal, you can either change the id to the same that you have or you can simply force the flash.


Edit: I just checked, it's the subsystem ID that's different, not the subvendor (that would've been weird). So you might have to reinstall the driver when you flash a vbios with a different subystem.

 

So its not dangerous for my sys ? Because when when i tried to flash, nvflash made a strange sound !!

 

Yeah, it always beeps when it shows a warning. I've done a lot of vbios abuse to the Nvidia GTX 470m when I put it in the G73JW and got a lot of warnings, some stuff should not necessarily be changed, but I never had a problem when changing the subsys.

Like I said, you can edit the vbios so that you don't get a warning.

 

I have to change : The board ID and the subsys ID !!

New problem, in nibitor, when i change this 2 values, the Vbios integrity is yellow not green !! Not dangerous ?

 

Change it, then save the vbios and then open it again. It will be green.

 

OK and after i flash it with Nvflash ?

 

Yes, exactly. nvflash -5 -6 filename.extension

 

OK thank yu

OK it worked !!! Thx a lot Now i have to restart the computer and reinstall the driver ?

Now i have a BIG PROBLEM : I restarted the Computer and when windows start, the sreen become black and i must push the power button !! What must i do ??

 

Restart in safe mode, uninstall driver.

 

Weird, never had this problem. I recommend flashing back the original vbios and then flashing the SW vbios without modifications, ignore the warnings. See whether this works. You can also flash the SW vbios directly in case you have it on the stick.
