Think i've broke my 9600M GT :/

Hey guys, think i've broke my 9600M GT.... i've overclocked it here and there... but not done the memory, well once, but only ran it for about 30 seconds, temps have always been 60's 70's due to the fan i've placed on the GPU...

it's undervolted at 0.89v, i've started having problems in games, artifacts, but if i tab out and go back in it's fine, i thought it was the undervolt, so i up to 1.0v and it's happening still... just tried a game, it crashed out and a BSOD about nvtddll whatever the name was and restarted my laptop....

it's not driver issues, i'm on 186.81.... when i have overclocked, it's been 630mhz and temps are cool... but i hardly overclock now and run at normal clocks, i dont go no higher, i have tried but only for a very short while...

sometimes i play a game it's absolutly fine no artifacts crashes etc, but then it's happening a lot more now...

any ideas?? should i go back to stock voltages?

Also, the 9600M GT came out of a MSI lappy, i flashed it with this BIOS:

Acer 62.94.38.00.04, could it be the bios thats the problem? anyone got a 6930G with 9600M GT DRR3 and could tell me what bios you're running?

thanks.

 

Goodness. Why did you Flash an MSI GPU with Acer GPU Firmware?
As mentioned before, flashing of BIOS was dangerous. 9500M GS spoiled and now 9600M GT.
The possible fix is you find your original MSI GPU(9600M GT) BIOS and flash it back to original state.
Cool temperature doesn't mean it is safe sometime. Some GPUs are not made to OC. You saw plenty of 9600M GT can OC well, it doesn't mean your 9600M GT can do it as well even with cool temperature. In addition, your 9600M GT is from MSI and now it is on Acer System. Some crashes is unavoidable sometime.

I think you get an ATI GPU in the future.
Cheaper and higher performance.

 

Ok, is that such a problem then, changing the bios to an acer specific 9600m gt drr3 bios?

well i've flashed it back to the firmware it came with, and default stock voltages.



the bios version is now that one ^

can changing the firmware cause problems like artifacting etc then? and undervolting, can that cause artifacting and crashing?

Thanks

P.S when flashing the GPU, what does the PCI subsystem doesnt match etc all about? is that a problem also?

thats the BIOS i did have...

http://www.techpowerup.com/vgabios/29076/MSI.9600MGT.512.080708.html

that one is the one i must have now as its MSI and same version, but isn't that dodgy using that firmware in an Acer laptop?

 

Ok just tried a game:

getting artifacts here:

If i tab out and go back in it goes.... is it dying?

 

Not sure. But you can try Acer firmware 1st and then try MSI firmware.
Yes. Undervolt can caused Artifacting in Games and crashes too as well as BSOD sometime.
However, a good undervolt will not affects games play or crashes and so on.
Undervolt may allow low temperature, so, can have a good OC.
You can have a good OC with low temperature but undervolted GPU will not able to OC too much due to the voltage supply is not enough.

OK. Now, turn everything back to normal/original like the 1st day you inject the 9600M GT in the AS6930G.
Original 9600M GT(with arctic silver).
Original BIOS firmware(no undervolt or whatever stuffs) that works for you during the 1st day.
Original GPU Clocks(no OC).
Original Geforce Driver(I think might be 186.81) that work for you during the 1st day.
Do not add your personal FAN(LOL, you showed a few days ago).

Just in case, please do know how to completely remove the Driver Forceware.
Unclean uninstallation and install a new Driver Forceware may cause some problems too.

 

I've had the acer firmware since day 1 i got it, ive now flashed back to original MSI firmware, no under volt. no overclock, default everything... 186.81 drivers...

that image from that game is what is happening now....

everything default..

Ill try re applying the gpu, and take the fans off, i cant see the fans doing any damage tho?

 

So, it is OK with your MSI BIOS?
Or still got problems? If then, back to Acer BIOS.

About the FAN, I don't know. Since you're trying to reach the Original State of the 1st day 9600M GT injected to your laptop. So, I suggest:
Original 9600M GT(with arctic silver).
Original BIOS firmware(no undervolt or whatever stuffs) that works for you during the 1st day.
Original GPU Clocks(no OC).
Original Geforce Driver(I think might be 186.81) that work for you during the 1st day.
Do not add your personal FAN(LOL, you showed a few days ago).

EDIT: Slept.

 

No its still got problems lol, thing is, the acer bios has been absolutly fine with it, its until i started overclocking it and using the fans on it... hmmm

Ill have a play around see what i can do.

 

That picture looks like a memory fault. Try downclocking the memory about 50mhz.
Its possibly by clocking the memory if you did, you've pushed it a bit too far (or the different bios you used could have had higher clocks than the native one).

 

Damn.... Well i put the memory on 900mhz for about 30 seconds, one time only, default is 800... plus, the bios i used was the same clocks as it was designated for the same card....

also.. i've just noticed that on that fan i had attached the GPU, there is a sticker on it saying "Magnetic Levitation System" does that mean its got a magnet in it? and magnet being that closed to the GPU, is not good, right??

 

Overclocking it the way you were is not good, hitting temps of over 100c is bad. I hope that its not dying on you but you need to becareful when overclocking due to high temps.

 

The memory could have been substandard already, and it was pushed that little too far, not every chip is made equal. Try underclocking the memory perhaps by modding the bios, or slacking off the timings. Its not a perfect but it might get you a useable card back.

 

Thanks guys i'll give it a go see how i get on, Cobra, i wasn't hitting 100 degrees mate, i'm not even getting over 75 now, i've took the fan off, left the case open...

The fan i had attached to the gpu has got a magnet in it, could that damage it?

 

Ok underclocked the memory 30mhz, seems to be running ok for now... i hope it stays that way.

 

If it only just went stable at about 30 under, I'd consider dropping that another 20. Memory doesnt make a MASSIVE difference to speed unless it's the bottleneck in your GPU, and dropping that extra 20 would give you extra leeway both to act as a buffer zone in case of further degredation, and also plain and simple stressing the RAM less. (dont ask why Im still up at 5am my time lol)

 

Sorry to hear your story, dude. Well, this is another good example that shows high temp is not not the sole factors that can kill a card, there are certainly other factors out there. You can still fry your card even if u have absolutely fine temp. As someone mentioned above some cards are just meant not to be OCed.

It's not advised to OC the memory not only because it has no temp sensors, but also because the memory chips on a video card usually have the shoddiest quality, i have read countless stories that tell the same thing, the memory chips are usually the first thing to die when a card being OCed too far.

As Alexrose suggested, if lowering the memory by 30mhz does good for you, i would decrease a little bit more to give your RAM more headroom. And you probably won't notice much performance decrease.

 

I am not sure about the FAN with MAGNET will spoil the GPU.
But it sounds MAGNET is bad for electrical applications.
Magnet can cause the metal chipset or screws or watever to get loose sometime due to the magnetic(dragging) force of the magnet.
Well, the stronger the magnet, the stronger the force of course.
I have 1 magnet which able to bend soft-metal, wires, small gears and thin metal plate.

Memory Clock does give huge performance impact.
I wonder why you have a normal or original Memory Clock Speed gives you problem.

 

Wierd, i've been playing games all evening and it's been perfectly fine :/ undervolted at 0.89v, maybe it was the fan after all.. i hope lol.

 

As expected. LOL.
While you showed the FAN you put. I was like impressed in the 1st place.
However, after you said it is "magnetic", I was depressed. LOL.
I hope your problem fixed too.

 

Never place magnetic devices near electrical devices. Magnetic flux can induce current and alter the operation of said electric devices, sometimes causing permanent damage.

On another note, Memory clocks are important to keep on stock, as the temperature sensors of the card are not monitoring that particular temp, and usually is not made to withstand high temperatures.
