ATI 4830 no ATI stream / opencl ?

Can anyone confirm if the Ati 4830 with 640 stream processors can do Ati stream / opencl or not.

I have tested mine on winxp32 xp64 vista32 win7 ultimate win server 2k8R2x64 and for some reason opencl / Ati Stream is not available.

I used GPU-Z.0.3.8 and GPU_Caps_Viewer_Setup_v1.8.2 all with the same results from driver 9.5 to 10.1 on above win versions.

Model:
SAPPHIRE 100265HDMI Radeon HD 4830 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP

Any idea if the 4890's has ati stream or actual working ati stream / opencl or not and with what brands it is actually working ?

Want to replace this 4830 with a 4890 as the RMA + shipping cost + time possibly 2 weeks without a card is the same as buying a new 4870 so might as well get something basic / server video card that I can do something with like the 4890 and have working NO 5800 driver issues / NO Sapphire brand.

+/- $200 budget.
