I recently built my first computer, the specs include an a10 5800k APU, AMD Radeon 7660D GPU,(this is the integrated GPU.) A A78M-E35 Motherboard, CORSAIR Vengeance 8GB (one stick), a 1tb Hard Drive, and a 550W PSU. I am getting extremely slow performance with the APU I have installed. For example, on the 3DMark Graphics Test, the average score for the A-10 5800k is 1366 and I am only getting 191. At first, I thought that another stick of ram would help, but for one stick of RAM to 4x the performance is crazy. I looked more into the scores and I realized that only 768MBs of my 8gb RAM was going into my AMD Radeon 7660D. The other benchmark had 2048MBs dedicated to the GPU. Also, the Memory Bus Clock is double on the other benchmark, mine being 667 MHz and the other one being 1200 MHz. I was wondering if there was a way to dedicate more memory to my GPU. Is this a bug or some sort of problem, I would really like to know. Thankyou.
