Introduction:

Kingston HyperX KHX6400D2LLK2/4G, 4096MB, PC2-800, CL4-4-4-12 Memory Kit

    When it comes to our computers, we'd love to always have the biggest and the best. However, reality indicates that isn't always possible. But that also doesn't mean we have to "settle" when it comes to memory options. For the PC enthusiasts who are looking for quality and value, Kingston offers the KHX6400D2LLK2/4G Memory Kit, a product in their HyperX DDR2 line. The HyperX DDR2 offers faster speeds, lower latencies, higher data bandwidths and lower power consumption than DDR. Kingston has this specifically to say about the KHX6400D2LLK2/4G:

"Kingston's KHX6400D2LLK2/4G is a kit of two low-latency 256M x 64-bit 2GB (2048MB) DDR2-800 CL4 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA components per module. Total kit capacity is 4GB (4096MB). Each module pair has been tested to run at DDR2 800MHz at low latency timing of 4-4-4-12 at 1.95V. The SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V."

Memory Information

KHX6400D2LLK2/4G

    The 2x2GB modules are packed in a single blister pack, which has pretty much been the standard for Kingston over the last few years. The label across the front has the model number of the kits and some of the specifications, as well as serving as security tape along the edges.

Ribbed Fins

     The heat spreaders on the HyperX modules are some of the nicest on the market. The blue on the aluminum stands outs, and the silver detailed area along top is not just for looks - it serves a purpose. The silver area is slightly raised and ribbed, which creates more surface area for more efficient cooling as well as aiding in gripping the modules. The heat spreaders are held in place with spring clips, and are secured to the RAM modules with double sided heat tape.

    Speaking of modules... What makes these modules on this 4gb kit so special? Well, to put it simply, how about double the memory capacity... and I'm not talking about 2GB versus 4GB. The new Kingston KHX6400D2LLK2/4G kit uses 8 logical banks as compared to the typical 4 normally used in DDR2 kits to reach the high memory capacities. This effectively doubles the throughput of the RAM.
