you will have to provide more info like what os what catalyst version when did the problem start and so on.
also what do you want to do with this card?
it only supports open-cl 1.1 and only has 470 or so streaming cells a rough gauge of power.
while a lot is packed into this little card it would take 3 of them to come close to say a hd 6870.
so be specific and give us as much detail as you can and we can answer your questions more directly and compleatly.
Was using this card for second monitor and some gaming. Was working fine with Windows 7 and when upgraded to Windows 10 now not. I called AMD and VisionTek and they referred me to the AMD site to download new Catalyst drivers which do not work. Waiting for AMD to advise or waiting for updated driver.
is this a second card running a second monitor or the main card running both monitors?
either way 15.8 installs dx 11 compliant driver that should work but inf open-cl or some
obscure library call is used you may need to install amd streaming sdk 3.0 download google that and it will take you right to the amd download site.
more detail is always better leave nothing out get right short answer first time.
