Testing Different Memory Speeds on AMD’s A8-3850 Llano APU

The Test System

Before we look at the numbers, here is a brief glance at the test system that was used. All testing was done on a fresh install of Windows 7 Ultimate 64-bit. All benchmarks were completed on the desktop with no other software programs running.

The AMD Test System:

AMD Llano APU Test System

The test system was run in dual-channel memory in four configurations:

  • 2x4GB at 1333MHz with 8-8-8-24 1T timings and 1.50V
  • 2x4GB at 1600MHz with 8-8-8-24 1T timings and 1.50V
  • 2x4GB at 1866MHz with 9-10-9-28 1T timings and 1.50V
  • 4x4GB at 1866MHz with 9-10-9-28 1T timings and 1.50V

We had to relax the timings at 1866MHz as the G.Skill memory kit would not run with CL8 timings at clock frequencies this high. The nice thing about testing these memory settings is that it is all done with the memory divider in the BIOS, so the GPU and CPU clock speeds remain constant throughout the benchmarking process. The Gigabyte GA-A75M-UD4H motherboard was
running BIOS F3, which was the latest build available when testing was
completed. You can see all of the CPU-Z and GPU-Z information for this test platform below.

The integrated graphics comes up as Radeon HD 6550D according to GPU-Z and we used AMD CATALYST 11.6 drivers was
used for testing.
