When benchmarking the Patriot modules I wanted to be sure to cover all angles. Some people like to run their memory at low latencies, some like to run their memory at high frequencies, whilst others prefer a mixture of both settings. Below is some information regarding the testing procedures and their results:

Stock Settings (533mhz / 2.2v / 5-5-5-9)

After being worried by the extremely high stock voltage of 2.6v listed on Patriot's website, I decided to be slightly more conservative and run them at a voltage known to be perfectly safe for D9 IC's - 2.2v. At this voltage the modules had no problems performing at the listed stock timings as speeds with 100% stability.

Lowest Timings @ Stock Frequency (533mhz / 2.35v / 4-4-4-6)

By increasing the memory voltage up to 2.35v I was successfully able to reduce the kit's timings down to a respectable 4-4-4-6 whilst also maintaining the stock frequency of 533mhz. Increasing the voltage past 2.35v did not provide any more headroom for tightening the latency, and as a result combinations of RCD and RP set to 3 proved unbootable.

Highest Frequency @ Relaxed Timings (592mhz / 2.35v / 5-5-5-15)

By relaxing the TRAS slightly and increasing the voltage to 2.35v I was able to increase the frequency of the modules to 592mhz. Yet again, extra voltage over 2.35v did not help push the modules any further, and loosening the timings to 5-6-6-15 produced only a small overclock increase up to 598mhz. Active cooling was also tried with the modules above 2.35v, but it certainly seemed like heat wasn't the issue.
