I recently upgraded my graphics card (marginally) from RADEON 4850 to RADEON 4870. My old model 4850 had 512mb, and one of the reasons i upgraded to the 4870 was that i needed 1gb of memory to keep upto date with new relases.
Anyway when installing my new card and booting up, Windows shows the memory as 512mb, as does GPU-Z and 'canyourunit'. However I know for a fact that the i bought a 1GB model, so why is it not being recognised?
If anyone can help it would be much appreciated
My specs are:
amd phenom II X4 850
4gb ddr3 RAM
* Also i dont no if this may be the problem, but when windows first updated my drivers and needed a restart, my pc bluescreened just before i could press ok. ( However i have checked and the drivers ARE up to date
