Kingston unveiled new HyperX DDR2 SDRAM memory products on Tuesday. The company's new modules are certified to run at 533MHz and 675MHz with CL3 3-3-10 and CL4 4-4-10 respectively. According to X-bit Labs these are now the fastest modules available thanks to the 675MHz frequency and slightly more aggressive timings than their competitors.
DDR2 memory products utilize FBGA memory chips for better stability, thermal efficiency, enhanced scalability and better overclockability. Additionally, DDR2 components themselves have some micro-architectural changes from the original DDR specs, such as, Off-Chip Driver calibration (OCD), On-Die Termination (ODT) as well as larger 4-bit prefetch, additive latency, and enhanced registers.
So far only three popular memory brands – Corsair Memory, Crucial Technology and OCZ Technology Group have unveiled 667MHz memory modules. Corsair’s and OCZ’s high-speed DDR2 are certified to operate at 667MHz with CL4 4-4-12 latency settings, Crucial’s product can work at 667MHz with CL4 4-4-10 timings.
Kingston's new HyperX DDR2 PC-4300 and PC2-5400 modules should be available immediately in 256MB and 512MB modules, as well as in 512MB and 1GB dual-channel kits. The 256MB modules cost $135 and $144 and 512MB cost $198 and $211, for 533MHz and 675MHz respectively. Dual-Channel kits should cost a little less than two separate memory modules.
