New Amd Firepro Graphics Card Keeps Crashing

Hi,

I have 12 Monitor setup that is run by three ATI FirePro 2460 GDDR3 512 MB cards. It is Dell T-7500 workstation with PCIe 2.0 slots & 12 MB RAM & Win-7 Ultimate.

Each card has 4 ports so each runs 4 monitors. I have been using this setup or last 5 years for displaying stock charts & using other regular applications including playing YouTube & regular videos. I DO NOT play any games at all.

I never had any problem with setup for last 5 years.

Recently one of the cards died so I bought a new one. But new one has identical specs except it has GDDR5 instead of GDDR3.

Now whenever I play YouTube videos, the new card crashes after few minutes. So 4 monitors that are connected to that video card goes blank & also keyboard & mouse freezes.

So I have to shut down the CPU using start button & Restart it & again all 12 monitors start working.

But then if I play YouTube videos, new card crashes after a while. Crashing time is random.

What seems to be a problem ? Is it because new card has GDDR5 instead of GDDR3 that other two cards have & thus it is not compatible with two other cards ? All cards are identical except the new one has GDDR5 instead of GDDR3.

Please help.

Thank you.

 

So all 3 cards and 12 monitors work just fine (for hours even) with other apps up until you play a YouTube video?

The RAM should not matter. Drivers do. Are all drivers fully updated? Is Windows current?

 

There is only one driver type on AMD site & that is the driver for AMD ATI FirePro 2460. I have installed the 2 year old driver but these cards are 5 to 7 years old. So although new driver package is available, it should not matter. OR does it ?

Yes, windows-7 is current.

 

It sure might. New drivers are often released to fix problems with old drivers and to add compatibility support for new hardware.

 

There is no change in hardware & current drivers have been working fine with old 3 cards. The new card is also 6 or 7 years old.
