Kingston has been making memory modules since 1987. In the last couple of years they have begun branching into the overclocker's market with their HyperX series of RAM. Already known for making high quality, affordable memory, many overclockers were curious to see how Kingston's performance line of memory would perform. Kingston began their HyperX line with PC2700 memory and recently have released PC4300 memory, producing memory for all the speed grades in between. Today we will be looking at their PC4000 1GB dual channel kit.
Memory rated at PC4000 or above is primarily intended for Intel based systems utilizing the i875 (Canterwood) and i865 (Springdale) chipsets, as well as, a few newer chipsets from VIA and SiS that utilize the Pentium IV processor. Not that memory rated at this speed won't work on AMD platforms, but the memory that fits that platform best is some low latency PC3200 or PC3500 memory.
Since Intel released their 'C' revision of the Pentium IV processor overclockers have been hungry to take advantage of the huge memory bandwidth performance the Pentium IV offers. However, many have had to run their systems using the system bus/memory bus ratios of 5:4 or even 4:3 instead of the more optimal 1:1 ratio. Kingston aims to help us out by offering a dual channel memory kit rated to perform with a 500MHz memory bus.

Kingston is using two different types of memory ICs on their memory modules. Originally they were using Samsung 5.0ns chips, however on the newer memory modules they have switched to Hynix 5.0ns chips. Both types of memory ICs are rated identically and have been shown to have almost identical performance. For more information about this check out this article at LegitReviews. For the record the review modules I tested had the Hynix ICs.
