1Gb V-Data PC3200 DDR RAM CL3 module by Adata

1Gb DDR400 PC3200 memory module from A-Data. 16 chips, 184 pins, 400MHz. Suitable for most desktops using PC3200 memory. With 64Mx8 chips which makes these modules very compatible with both older and new systems.

V-Data is the value memory range from A-Data, one of the worlds largest memory module manufacturers.

Further details from the manufacturers website:

The DDR400 module for desktop is a double data rate module composed of CMOS Double Data Rate SDRAMs in TSOP-II 400mil 66pin package and one 2Kbit EEPROM in 8pin TSSOP(TSOP) package on a 184pin glass–epoxy printed circuit board.

DDR400 is a dual in-line memory module and is intended for mounting onto 184-pins edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
