Asus G73jw Shutdown GTX460m overclock GPU *Safety shutdown forced* (possible solution?)

Hello friends,
As I commented in another forum, I decided to create this one to try to solve this problem.

I have in my Overclock to 800Mhz GTX460m possibly Stable
And then I put the VBIOS Edited to 0.962 volts, also remained stable up to 840Mhz - 850Mhz

However, I noticed that there is some type of current limiter on the motherboard that prevents the MXM card to consume more energy than the established (amps "A")

thus the system is shutting down the computer completely randomly in some games, or a scene that Consume All the graphics power of MXM card.

Posted two videos for you to see WHAT is happening more
A video with the GPU at 800MHz
and another with the GPU 840mhz
Asus g73jw 800Mhz GPU (safety shutdown - Overcurrent GPU Overclock -) .AVI - YouTube
Asus g73jw 840Mhz GPU (safety shutdown - Overcurrent GPU Overclock -).AVI - YouTube

In general the Scene That Pulls more graphics power is the Carcyclopedia MAFIA2
Before I get into the Mafia 2, I show the FurMark running smoothly, and without graphical errors due to overclocking.

I put some more descriptions that might analyze the Video.

By the way the system shutdown happens, I'm almost 100% sure that the motherboard limit the maximum current that can MXM card request.
This would be to prevent fire in case of short circuit in the MXM card.

What do I want to do is make a kind of "electric BRIDGE" between the MXM card and the power supply on the motherboard

I think it's a simple thing, but I have no idea what is the MXM connector on the board which is the input energy and tension in which the MXM card works.

If anyone can help me, providing more connection information MXM card, be grateful.

I know I can spoil my notebook, but I'm Determined to take that risk, after all nothing ventured, nothing gained.

Thank you! I'm sure my theory is well founded, and that will be simple work around that.

 

Why don't you get that kit that allows you to run desktop graphic cards on laptops? :B

 

I have the same problem, when i overclock my gpu, after 30-1H of gaming, SHUTDOWN

 

Today I did some more tests, and had more evidence that my theory is correct.

I found that gradually lowering the game resolution, the shutdown does not occur.
that is, lower resolution, lower power consumption of the card MXM.

Really for us to achieve stable in our Overclocking G73JW, must remove the current limitation of the motherboard.

Who knows until we can reach a stable overclock of 880Mhz GPU. =)

While I do not find as "electric bridge" in the MXM card, the temporary solution to the shutdowns is that I mentioned, reduces the resolution of gaming.

Anyway, this weekend, I will disassemble my G73JW To find out more about the motherboard and MXM Card.
So if anyone has more information on the operation of MXM cards, tell us here..

 

I would first try using a higher rated power brick

 

Hm i think its the power adapater which is overheating or something like that !!

 

You refer to a more powerful power supply?

I've tried with a power of 180 watts, and have the same problem.

because the current limitation is occurring in the motherboard.

Below I posted another video where I show that the problem is turned on the current limitation by the motherboard, opposite the MXM card.

We need to find a way to deceive the current limit.
And with that our MXM card will have all that extra energy you need for overclocking.


.

 

WHAT would help me to make this modification, it would be some images showing the wiring diagram of MXM cards.

or else, information on where the entrance is Power MXM card. and the tension of this graphics card work.

I am very hopeful that this will work!
I think it will help many people maintain a stable overclocking (no shutdowns) on your Asus G73
....

 

I'm not sure that just adding juice to your GPU will fix your problem. Too much juice (or bold-fonts) may ruin the experience.

 

PCI.Express.Specifications

 

remembering back to the 7900GT days, i used a pencil mod to prevent overcurrent. as well as an ASROCK motherboard. for voltage on the CPU overclocking.

I think this would be the best route to take is finding the correct registers on the board and lowering the resistance via pencil to fake board into thinking current is well within its limits. or bangin on asus's door asking them to modify their board bios stating your having shut down problems and thier overcurrent limitation is set to low... if it is in fact a software thing.

 

Hello friends, After a whole weekend of testing, with my G73JW completely dismantled, I could not find a way to make GTX460m off the system.

I tried all possible ways to feed the GPU with MXM energy directly on the board,
But nothing worked. the system continues with the shutdowns.

until I tried a direct connection with the MXM card power supply, did not work.
disconnections Videos Shown in the beginning of this topic still occur.


By the way, the MXM card also operates at 19 Volts.
When in battery, the MXM card operates at 15 to 14 volts.

Apparently Pudi From what I see, the MXM card send some sort of signal to the motherboard is off.

That is, the MXM card has some protection built in, that when working up the capacity, it sends a signal to the whole system off.

Now there are two paths.

Trying to Find the path of electric MXM card which sends the signal and isolate

or

Try to locate the component on the motherboard that has the ability to turn off the system, and then lock the component.

Honestly, I will not do it now.
I was very tired trying to solve it.
and at the end was frustrating.

ASUS really just want to sell their notebooks, they do not care about our ideas

 

Oh yes, Asus should wholeheartedly support dismantling and messing with our laptops and dramatically increasing the chance of hardware failure, all for an extra 10-20mhz gain in GPU clockspeed.

 

A agree they should, if they want my continued business

Not only because i have certifications, and a full time job as a technician, but dismantling would somehow void my warrenty, when i can fix something that they can not.

And BTW, i haven't RMA'd anything my entire life. Nor filled a claim on my auto insurance. Yet i get charged out my *** for it

 

So you represent 0,01% of the market. Possibly lose a couple of laptops sold or lose millions in additional broken laptop repairs? That's a tough one.

 

True, isn't it a shame. They should reserve enthusiast's name for what it actually is, and not include the other 99.98% of the market.

Hell we can all name our old 386 computers as blazing fast... at least that how they marketed it then......

Don't name a computer an enthusiast's computer if your planing on limiting what he can do with it.... Limit the warrenty and let the Enthusiast loose.

Take back the name, and slap a premium price tag on it and save the real enthusiast the hassle of dealing with mediocore or advanced garbage.

Clevo has seem to be getting this right, from what ive seen...

Why brand and advertise your laptop an an "extreme enthusiast" laptop, when there not one.... NOT ONE option to change bus speeds, ram timings, or hell anything for that matter via bios???? IMO its entry level bios slapped on premium hardware... and that qualifies for enthusiasts. Shaming...


Sorry for the rant

 

An enthusiast doesn't read ads. He reads the specs, benchmarks, reviews and system manual. Ads are for people who buy HP or Apple.
Asus does not make enthusiast laptops. Only Clevo and Alienware do.
Asus makes good quality, nice looking mid-range gaming laptops. And that's what you've bought.

 

I agree, It is a midrange laptop... I wish I would have found this site before i purchased the Asus.. I was in a crunch bind, and needed one asap. I've read reviews, and they were claiming its an enthusiast laptop so i pulled the trigger.... *Bangs head on desk* Never again thou. Clevo is deffinitly my next wallet drainer. I can't stand proprietary hardware thats so similar and has features that can be changed but brander decides not to let you change them...

I had an RCA5000 HD-DVD player back in the day, which RCA takes forever to get a firmware update.. Toshiba was rolling them out left and right... So I flashed Toshiba over the RCA player, and worked flawlessly ever since.

 

Hi
maykon_helver have you found a solution to this I have the same problem when flying in FSX?

Asus G73JW-TY190V - i5 460M/ 4GB / 500GB / 17" TFT / GF GTX 460M

 

A very frustrating issue... more and more (as this thread states), I am realizing that the G73jw is a mid range gaming laptop, not an enthusiast rig.

If anyone reads this forum and is looking for more data that could possibly solve the issue, take a look here:

http://forum.notebookreview.com/asu...3645-g73jw-shuts-down-if-i-pulled-plug-6.html

I've linked numerous screen shots of monitoring data, settings, error messages, and the like. To put it simply, the G73 is a very capable laptop heat wise. But this limitation, likely in the motherboard, prevents any sort of significant overclocking.

Anyway, perhaps one day ill stumble across a fix in a random forum....
