i dont aware any software could do RAM overclocking. or you means benchmark software for RAM ?What are the best softwares for ram OC? and is there any benefit to faster rams?
Faster RAM or overclocking of RAM only beneficial in benchmarking. like in MaXXmem software to analyze how faster your ram is as compare to rivals and also latency info. lower the latency higher performance will be. In 3DMARK 11 physics benchmark, Memory OC impact greatly with along with CPU.
Gaming performance will not be affected by RAM overclocking. marginal difference.
