Kingston Technology, a top maker of high-performance memory modules, announced the release of HyperX modules capable of achieving unprecedented speeds of 750MHz, which is currently the world’s record for officially made RAM product. The products, however, come months after they were supposed to be released.

Kingston’s HyperX KHX6000D2-series of memory modules are rated to operate at 750MHz with CL4 4-4-12 timings and 1.9V voltage. The products were first described in late January, 2005, and were said not to feature any expensive and specially designed PCBs, but used standard JEDEC-certified print-circuit boards.

“Like all HyperX products, the new 750MHz module was designed and qualified by careful selection of the best components, then assembled and tested for ultimate performance. Kingston's engineering lab was able to reach an unprecedented 866MHz with these new modules,” said said Mark Tekunoff, senior technology manager, Kingston

HyperX PC2-6000 modules are available immediately in 256MB, 512MB, and 1GB configurations, but in limited quantities, the company said.

Kingston originally indicated that one of the problems with the launch of commercial high-speed memory modules was the absence of mainboards that could stably operate with 750MHz memory: initially only ASUS P5AD2-E could easily handle 750MHz DDR2, while even ABIT’s Fatal1ty i925XE could not be fully stable with such speeds. Now it is expected that the HyperX PC2-6000 modules are compatible with broader set of mainboards.

Previously the world’s premier DDR2 memory modules were Patriot’s Extreme Performance PC2-5600 (700MHz) with CL4 3-3-12 timings.
