Mushkin sent us a total of three kits; one kit was for PC2-5400 and two were PC2-6400. Below are the main technical characteristics of the modules:

All of the modules come in plastic packaging. The cardboard background of the two PC2-6400 modules adorns the new green and white Mushkin logo, which in our opinion looks refreshing. All of the modules were equipped with Mushkin’s “Frostbite” heatspreaders, which are larger than standard heatspreaders.

Each memory kit from Mushkin that we will be testing belongs to a different category. There are three categories in all. “HP” stands for High Performance, “XP” stands for Extreme Performance, and “EM” stands for Enhanced Memory. The last one, as the name suggests, is aimed at the value market segment. The main differences between the modules are the different chips used in them, which in turn offer different levels of performance.

Maximum Clock Frequency, timings 4-4-4-12
Model	HP2-5300 996521	XP2-6400 996523	EM2-6400 996527
Max Frequency [MHz]	390	520	470
Voltage [V]	2.10	2.45	2.25

The overclocking results of the two PC2-6400 memory kits come out to be particularly interesting. The XP2-6400 ended up needing the highest voltage our motherboard could offer, 2.45 Volts. Its overclocking performance, however, turned out to be quite impressive, a result of the Micron Fat Body D9 memory chip that the module comes equipped with. The Enhanced Memory kit we tested, which as we said before is classified as value RAM, turned out to have an overclock of 17.5% while running at timings faster than the default values.
