Memory overclocking help DDR3 1600 - ?

[geordiejc]

I'd like to overclock my memory and see if i can get a bit of extra free performance.

CPU 4770k 4.3Ghz @ 1.27v (Evo 212)
M/B MSI Z87 Gaming G45
Kingston Hyper X DDR3 1600 XMP 9-9-9-27 @ 1.65v KHX1600C9D3K2/8GX https://www.kingston.com/datasheets/khx1600c9d3k2_8gx.pdf

Anyone want to give some advice ?

Benchmark for baseline: XMP enabled.

Thought i'd try undervolting the XMP profile from 1.65v to 1.5 and tightened T2 to T1 lower latency and faster read/write/copy and the voltage on the memory controller on the cpu hs been reduced by 0.15v! (less heat hopefully)

Dialed in 2-10-10-10 @ 1866mhz 1.65v - Faster Read/Write & Copy

i'm a little torn between saving 0.15v on the 1600mhz 1-9-9-27 vs the 1866Mhz 2-10-10-10 @ 1.65v.

I'll do some gaming benchmarks tomorrow.

Any help appreciated here guys.
