Both products appear to have analogues on the market, as earlier this month Corsair Memory announced its XMS2 Series 4300C memory modules rated to operate at 538MHz with CL3 3-3-8 latency settings, while a number of companies, including OCZ Technology, hit 667MHz DDR2 speed-bin with CL4 4-4-12 latency settings.More info at X-bit Labs
In about a month time or later OCZ targets to release its 733MHz and 800MHz DDR2 memory modules with CL4 4-4-12 and CL4 5-5-12 timings respectively. Both are likely to be exclusive offerings by Sunnyvale, California-based OCZ, who indicated plans to release DDR2 memory modules with 800MHz clock-speed targeting overclockers and enthusiasts back in the first half of the year.
OCZ to launch higher speed DDR2 memory modules

OCZ is soon going to launch a number of new high-end DDR2 SDRAM memory modules within a few weeks. Planned are PC2-4200 and PC2-5400 memory sticks running at respectively 533MHz and 667MHz with CL3 2-2-12 and CL4 3-3-12 latency settings.
