AMD revamps its roadmaps, Intel delays its Prescott chips, memory makers continue to innovate the DDR memory for extreme overclockers. One of world’s most-recognized memory module maker OCZ showcased its DDR556 sticks at Comdex, but only behind the closed doors.

Earlier this year both OCZ and GeIL revealed their DDR memory modules at 533MHz – a speed-mark originally set for DDR-II devices. The Inquirer discovered at Comdex that 533MHz is not the edge for conventional DDR SDRAM – reportedly OCZ showcased its ready to ship 566MHz memory modules based on currently available DDR technology. The memory modules are programmed to function at CL3-4-4-8 timings – not really aggressive settings, but still enough to pretend on a bit improved performance over memory modules at 500MHz and 533MHz.

There is no information when the 566MHz memory module kit will be available in retail and I am also not sure about its pricing. Typically, modules for overclockers are considerably more expensive than ordinary solutions for the vast majority of consumers. Since OCZ’s so-called PC4500 sticks are even more advanced it terms of speed compared to the upcoming DDR-II standard DIMMs to be available in the second quarter next year, we may expect the pricing on such modules to be at an extremely high level.

Even though the market of overclockers and enthusiasts is relatively small, shipments of computer hardware specially tailored for hardware freaks has been seeing a tremendous growth within the last couple of years.
