At Xtreme Resources we recently received some samples of the latest iteration of Corsair's DDR550 memory, TwinX1024-4400C25PT. It consists of 2 x 512MB TwinX paired memory rated at PC4400 (DDR550). Corsair previously produced DDR550 memory, but the difference was those modules used memory timings of 3-4-4-8. In a press release for this new memory, Corsair advertised "their fastest ever DDR memory module, a DDR550 module that supports very aggressive 2.5-4-4-8 latencies".
