GPU stress not working (Sapphire HD4850)

[HiSpeed]

Hello,

I've recently installed an old Sapphire HD4850 with an old Asus P5B-E.

When testing the system stability, I have been surprised to see the GPU stress not working, nothing moves.

I have been obliged to use OCCT instead (I use XP Pro SP3).

Do you have an explanation ?

A while ago AMD made a decision to not release their Catalyst drivers with APP (OpenCL) support for pre-HD5000 cards. AIDA64 System Stability Test requires an OpenCL capable GPU device to stress the video adapter(s). Hence this is a video driver limitation, and not the fault of AIDA64. If you decide to upgrade your card in the future to a HD5000 or later card, then you will be able to use the GPU stress test in AIDA64.
