My RAM has an XMP profile for DDR3 1600 @ 9-9-9-24-CR2 but I wanted to overclock it. So far I've gotten up to 2600Mhz @ 11-13-12-20-CR1 with 1.65v on the DRAM but my read speed hasn't gone up much. The XMP benchmarks show 23.1GB/s read, 23.2GB/s write, 21.1GB/s copy and 55.4ns latency but when overclocked I can only get 25.4GB/s read, 37.0GB/s write, 27.7GB/s copy and 45ns latency. WHy would write speeds go up but not copy or read much? Maybe I need to tweak my timings?
