Hi,

For some time now I have major trouble with my ASUS GF4 Ti4200 card on EPOX 8K3A mobo. I have run it for about 1 1/2 years without any problem, but now every time I run a game in D3D or OpenGL the system is guaranteed to malfunction. I get:

* crashes to desktop
* crashes to reboot
* crashes with memory errors like:
"The instruction at "0x01d1f6e9" referenced momory at "0x413ab11". The memory could not be "read"."

Now the weird part: it almost always crashes within 2 minutes max., but sometimes it only crashes after a longer time, about 20 mins or so or even longer. I played several hours once without the problem :confused: .

>>This did NOT happen after a driver upgrade or specific change in software, it just started to happen.<<

I tried:
*Reinstalling the card, using different drivers (45.23 and 53.03)
*Reinstalling DirectX 8.1
*Upgrading to DirectX9.0b
*Underclocking the card
*Running low resolution
*Putting an extra fan on the graphics card
*Putting new thermal paste under the GPU cooler
*Testing main RAM
*Testing DirectX
*Testing using 3Dmark, which also randonly crashed
*Several other test suites, but none found anything
*Then I got desperate: so I tried a complete Windows XP reinstall with only the 45.23 driver and DX9.0b
*and I'm sure I've forgotten to list some more things I've tried.

So I conclude:
*It is NOT a heating problem, because the card doesn't even get warm, let alone hot.
*It is NOT a driver problem (or else I would have had problems before).
*It is NOT a BIOS problem (or else I would have had problems before).
*It is NOT an OS problem
*It is NOT a software conflict (since a totally clean Windows malfunctioned as well)

Then I replaced the card with a GF3 Ti200 from a friend, and that card does work well (but slow ;-). So I have a strong suspicion that something is wrong with the onboard RAM of the graphics card.

So my questions are:

:confused: 1) Is there a way to test the onboard RAM on the graphics card? I really can't find any tool on the internet like DocMem e.g, but for graphics cards.

:confused: 2) Does anyone have another idea how to find out for sure that it is the card that's broken?

:confused: 3)Does anyone know something else I can try to get it working again?

I want to be 100% sure it is the card before I go and buy a new one...

Thanks a lot in advance for any advice, becasue it's making me :banghead:!

The only way to really find out if it's the card is to put it in another computer and test. Make sure you get a computer that is known to have fully functional components, then swap out the graphics card. If you get the same errors, then you know for sure where the problem lies.

I wanted to try that, but it doesn't fit into the laptop ;)
But yes that's something I should try at a friend's when I have the time next week.

Thanks for the freakin-fast reply!

Any other suggestions anyone?

If you put in the GF3TI and it works perfect, but then you put in the GF4TI and it crashes, it's a good chance your GF4TI is dead.

Try to get an RMA/Warranty replacement from Asus. If that doesn't work, you can buy a refurbished GF4TI4200 for $50, or a new GF4TI4600 for $100, but I would sooner recommend an FX5700NU or higher for you so that you'll be prepared for DX9.

I'll put the card into another PC this week and see if it crasheds there too.
If so, I'll get myself a new DX9 card.

tnx 4 your replies!

If you do spring for a new card I'd certainly recommend either a 5900XT or an ATI 9800 Pro for the mid-range priced cards.
