Overclocking

Now that the stock benchmarks are out of the way, let's see how much farther we can push the EVO X II's on each of our test systems. At stock, the EVO X II’s run at a speed of 3600MHz at a voltage of 1.35v with CL 18-20-20-40 timings.

In our Intel system the EVO X II’s refused to post at anything other then 3600MHz even with some more voltage. So, we moved the EVO X II’s to our AMD testbench and received much better results. On our AMD system, we were able to achieve 3933MHz at stock voltage, which is a 433MHz gain. We did try to bump up the voltage to see if I could break 4000MHz, but couldn’t get it to post.

Now that we have successfully overclocked the EVO X II’s to 3933MHz, let’s see how it improved our read/write/copy speeds. Using the AIDA Cache & Memory Benchmark, we found modest gains across the board with the stock Read/Write/Copy being 54.8/52.4/54.6 GBs and the with the overclock applied, we were able to hit 55.9/55.1/56.4 GBs. That’s an increase in performance of approximately 2% in read, 5.1% in write, and 3.2% in copy.

As you may know, running past 3600MHz, you are no longer coupled with the stock infinity fabric clock and is now running in 2:1 mode as opposed to coupled mode. On our test system, we were able to overclock the infinity fabric to 1867MHz which allowed us to run the EVO X II’s at 3733MHz and still be coupled to the infinity fabric. This yielded us similar results to our 3933MHz overclock with a faster read speed and slightly lower write speed but did reduce our latency by about 5ns to 74.9ns.
