The low voltage had me hoping for some massive clocks or at least running tighter timings than the stock 8-8-8-15 timings, but CAS 8 was it. Increased voltage or loosening the sub timings did not get me any tighter than CAS 8 at 1333MHz. While that was a disappointment, the modules did have some decent headroom for overclocking and reached 1660MHz with 1.65 volts. This 327MHz increase amounts to an almost 25% bump in clock speed that shows up as about a 20% hike in synthetic benchmark scores.
