AMD Trinity Linux Memory Performance

Following the initial AMD A10-5800K Trinity on Linux article earlier in the week, many forum goers were discussing the impact that the system memory speed has on the overall performance for this latest generation APU. In this benchmark are results looking at the impact of the Linux performance as the DDR3 memory operates at speeds from 800MHz through 2133MHz.

Other publications have also looked at the impact that the DDR3 memory speed has on the AMD Trinity performance, which is being done here in this article but this testing is being done under Linux, of course. A variety of CPU and GPU benchmarks were run from Ubuntu 12.10 on this AMD A10-5800K setup with MSI A85XA-G65 motherboard while the DDR3 operating frequency was controlled from the UEFI/BIOS. All other system settings remained the same throughout the testing process.

The DDR3 RAM used for this Trinity Linux memory performance testing was two 4GB sticks of Corsair Vengeance CMZ8GX3M2A2133C11B. This 8GB of Corsair memory is designed to run at 2133MHz with 11-11-11-27 timings at 1.50V. This 8GB memory kit retails for less than $60 USD within the United States.

The MSI A85XA-G65 does support running up to 2133MHz for the Trinity APUs. The memory frequencies tested were 800MHz, 1066MHz, 1333MHz, 1600MHz, 1866MHz, and 2133MHz.
