The OCZ SPD outlines timings for running the modules at DDR3-1066 at 1.5V. While the sticks do run at this speed, voltage, and timings and the SPD functions properly in the BIOS as a goal for the timings and FSB : Memory ratio, it is not the advertised speed. This means that regular users who put the memory in their rig will have their memory running at 1066MHz if all settings are at auto, which might be frustrating for the average user.

Moving the memory to 1333MHz at 1.75V proved to be painless. At 1333MHz, the modules ran well at the stock timings, but didn't POST at any lower timings. With a little bump in voltage to 1.83V, the memory runs nicely at 1472MHz, still at stock timings. This is the closest my motherboard can come to the 1.8V upper bound in the warranty provided by OCZ. More voltage at 1.92V, and the sticks were able to top out at 1500MHz running stable. Needless to say, the voltage of this RAM was crucial to its stability. Oddly, loosening the timings didn't seem to have an effect on overclocking range.

All tests were run on an entirely idle system, with the CPU clock at 3.0GHz. Each overclock was tested with an hour long CPU/RAM OCCT test for stability before testing. Every test and benchmark was run five times, and the average result was taken.

We see some pretty good numbers here, continue on as we wrap up this review with some conclusions.
