Transcend TS256MLQ64V5U DDR2 533 U-DIMM 4-4-4 2Rx8 2GB

This 2GB memory module from Transcend is a dual in-line device intended for mounting into 240-pin edge connector sockets. Its synchronous design allows precise cycle control with the use of a system clock. The module also allows data I/O transactions on both edges of DQS, while the range of operation frequencies and programmable latencies are useful for a variety of high bandwidth, high performance memory system applications.
