MODTHEBOX would like to thank Heather from Kingston Technology for providing the Kingston Hyper-X KHX4000K2/1G DDR Memory Kit for review.

Kingston

Introduction:

The combination of high performance computing and the art of overclocking to push components far beyond the manufactures suggested specifications have provided great achievements for not only for hardware architecture over the last year but enthusiasts as well. In order to meet the demanding market to supply quality products that will perform well beyond the dwelling stock speeds and take advantage to the latest architecture, many manufactures have conformed and introduced a variation of extreme performance solutions into their product line up. With a reputation for value ram, Kingston Technology based out of Fountain Valley, California is the world's largest independent manufacturer of memory products for desktop computers, notebooks, servers, workstations, laser printers, digital cameras and hand-held computers. Introduced last year, the HyperX series of memory is Kingston Technologies offering designed for extreme performance and gaming. Today in MTB Labs, we will be evaluating the Kingston HyperX KHX4000K2/1G Memory Kit.

Specifications:

The Kingston Hyper-X KHX4000K2/1G DDR Memory Kit is one of several memory module packages available on the Kingston Technology website. Frequencies for the HyperX line range from PC2700 to PC4300 and are available in 512MB, 1GB and selective 2GB kits. The Hyper-X KHX4000K2/1G kit has been designed specifically for dual channel architecture operation with a rated speed of DDR 500Mhz and a total capacity of (2X512MB) 1GB. Here are some specifications taken directly from the Kingston Technology website:

The Kingston Hyper-X KHX4000K2/1G DDR Memory Kit arrived in plastic retail packaging. A transparent cover showcases the modules along with a product model number and Kingston Technology branding label sleeve. Included in the package are the Kingston Hyper-X KHX4000K2/1G DDR modules and a small printed manual that outlines the proper installation procedure and warranty information

Out of the packaging, my initial impressions of the Kingston Hyper-X KHX4000K2/1G DDR modules were very positive. The Kingston Hyper-X KHX4000K2/1G DDR Memory Kit contains of two 512MB DDR500 CL3 SDRAM memory modules, for a total combined kit capacity of 1GB. Each module consists of sixteen 32M x 8-bit (8M x 8-bit x 4 Bank) Hynix DDR500 SDRAM ICs. I was unable to attain the exact Hynix IC model number. The Kingston Hyper-X KHX4000K2/1G DDR modules are designed for an operating frequency of PC 4000 or DDR 500 (250MHz) at 2.6V+ with conservative timings of 3-4-4-8-1. The five-digit number represents the CAS Latency, RAS-to-CAS Delay, RAS Precharge Act-to-Precharge Delay and Command Rate values respectively. Lowering the CAS latency will yield the largest performance increase yet plays a key role with stability at high frequencies. The lax timings will strike most as a clear bottleneck yet the high speed of 250MHZ+ front side bus (synchronous) with the speed of most recent processors easily counter balances the lax timings as a much more bandwidth can be communicated from the memory to the processor.
