A Japanese memory module maker is selling DDR SDRAM modules at speed bin that exceed that of the fastest brand-name DDR and DDR-II products available on the market today. The modules do not only boast with extraordinary performance, but are also quite affordable.

KuroutoShikou, a Tokyo, Japan-based firm known for rather extravagant PC hardware, has released memory modules at 560MHz, 10MHz higher compared to the Corsair XMS memory modules at 550MHz. The world’s highest-speed memory sticks for personal computers are based on HY5DU56822CT-D5 TSOP (Thin Small Outline Package) chips from Hynix and are available in 512MB versions. Memory products are not equipped with heat-spreaders, a very surprising peculiarity of high-speed modules today.

The fastest massively available memory modules these days – Corsair XMS4400 clocked at 550MHz – are capable of working with 3-4-4-8 latency settings at 2.75V. KuroutoShikou declares 3-4-4 latency settings at 2.85V voltage for its 560MHz modules.

A report over Akiba PC Hotline claims that a single 512MB DDR560 memory module from KuroutoShikou is quoted at about $130 in local stores, a pretty low price for a very powerful product intended for overclockers. Corsair XMS2 CM2X512-4300 (DDR2) memory modules cost about $270 per unit in Tokyo, Japan. Corsair Memory CMX512-4400PT (550MHz) DDR sticks are quoted starting from $195 in the USA. Typical DDR modules at 533MHz are priced from $160 in the USA.
