Testing this 6GB set of water cooled modules from Kingston, the HyperX H20 PC3 16000 will require the use of a small overclock to get the rated speeds. To keep the CPU close to its 2.66GHz clock speed, I will be reducing the clock multiplier and raising the bclock to get the 2000MHz rated speed with latencies of 9-11-9-27. The testing will include both stock and overclocked settings to see just how much headroom this set of modules has. Each set of modules is tested in this method to keep the CPU as close to the 2.66GHz default speed as possible while maximizing the memory speed. The voltages used will be all the available options in the BIOS to reach the maximum clock speed, while using the default 1.65v for the stock testing.

These modules from Kingston come from the factory with latencies of 9-10-9-27 - already pretty high up on the latency chart, so I was a little suspect as to the amount of headroom left on these modules. Those fears were unfounded as there was almost 200MHz left in the bank that ran right up on the limits of my poor Core i7 920's memory controller at 2190MHz. At the limit I would start losing a single module in this triple channel group of modules so any higher was out of the question, regardless of timings and voltages. To reach the 2190MHz limit, I had to increase the QPI voltage and bump the IOH voltage up a few notches to get the memory stable as well as bumping the vdimm up to 1.70 volts. However, 9-10-9-27 are not latencies that beckon the enthusiast to come hither. These modules do have the ability to run 7-9-7-27 at the 2000MHz level with a bump in the memory voltage to above that which Intel specifies as unsafe at 1.72v. With the ability to liquid cool these modules, heat due to voltage increases becomes a non issue.
The maximum memory speed for each set of modules when overclocked is a measure of how well the modules ran on these particular modules and test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware.
