DDR3 is CORSAIR DOMINATOR CMD8GX3M4A1600C8
Due to the interference with Cooler, the test configuration changes to 2GBX2
The spec is DDR3 1600 CL8 8-8-24 1T 1.65V
2GBX2 version is all black and 2GBX4 version is partial blue.
Two versions are different.2GBX2 price is around 130USD.
Using GIGABYTE GA-MA785GPMT-UD2H to test DDR3 performance
DDR3 1600 CL8 8-8-20 1T 1.600V
Sandra Memory Bandwidth - 8981 MB/s
EVEREST Memory Read - 13735 MB/s
DDR3 1600 CL7 7-7-21 1T 1.750V
Sandra Memory Bandwidth - 9415 MB/s
EVEREST Memory Read - 13760 MB/s
You can see DDR3 bandwidth are some different in CL8 and CL7
Besides, AMD CPU built-in memory controller hasnít improved for years, which are why DRAM bandwidth is still far behind Intel platform.
If you use 790FX chipset, DDR3 bandwidth will be higher 500~1000 MB/s. 790FX can set this memory set in CL6.
More high-end AMD chipset also improves more DDR3 bandwidth.
