Seven 8 GB DDR3 Memory Kits For Your AMD A75 Motherboard
By

Because integrated GPUs generally employ shared system memory, RAM performance has a significant effect on gaming frame rates. We're testing seven 8 GB DDR3 kits that manufacturers tell us are a perfect match for AMD’s mainstream Llano-based APUs.

Test System Configuration
APUAMD A6-3650 (Llano): 2.60 GHz, quad-core, 4 MB L2 Cache, Socket FM1
MotherboardASRock A75M, A75, version 1.02, BIOS P1.40 (07/21/2011)
APU CoolerRosewill FORT120
GraphicsIntegrated Radeon HD 6530D: 320 Shaders, 600 MHz GPU, shared system memory
Hard DriveSamsung 470 Series MZ5PA256HMDR, 256 GB SSD 
SoundIntegrated HD Audio
NetworkIntegrated Gigabit Networking
PowerSeasonic X760 SS-760KM: ATX12V v2.3, EPS12V, 80 PLUS Gold

OSMicrosoft Windows 7 Ultimate x64
Graphics and ChipsetAMD Catalyst 11.6


ASRock’s A75M surprised us with an incredible DDR3-2252 memory data rate in our recent Six A75-Based Motherboards For AMD’s A8 And A6 APUs story. While the presence of only two DIMM slots might have helped the board achieve that high mark, each competing 8 GB kits consists of a single pair of modules. So, it all works out in the end.

Benchmark Configuration

Three games will help us gauge the actual performance benefit of these module sets. Though we have doubts about Crysis, the other two titles should at least be playable using the A6-3650 APU’s Radeon HD 6530D GPU at high image quality, 1280x720 display resolution, and minimal added features.
