    Cape Verde R7 250 Dual Graphics with A10-7870K?

    hippie403

      I recently put together a new APU based system

       

      APU: A10-7870K

      GPU: Gigabyte R7 250 OC    GV-R725OC-2GI (rev. 2.0)

      8GB (2*4) GSkill 2400MHz DDR3 RAM

      Windows 7 64bit

       

      Runnning Crimson software     15.30.1025-151117a296575C

       

      The GPU was supposed to be a Rev 2.0  1100 MHz clock  1800MHz 2GB DDR3 RAM

      card which should have been compatible with the APU.

       

      Turns out I was shipped a Rev 3.0 card which is  720MHz clock   1600MHz DDR3 RAM.

      Apparently the Rev 3.0 card is Cape Verde chipset rather than Oland!

      I think it has 512 shaders rather than 384.

      3DMark11 identifies the card as Radeon HD7750(X2).

       

      I thought the A10-7870K was only compatible with Oland R7 cards?!!!!!

       

      Dual Graphics is enabled and seems to be working, do I have any cause for concern

      with Rev 3.0 card versus Rev 2.0 card?

       

      Should I plug the screen into the on board graphics,

      because it is clocked faster 886 vs 720 and has more memory bandwidth, 2400 vs 1600?
