4GB (2GB 256M x 72-Bit x 2 pcs.)

DDR2-533 CL4 ECC 240-Pin DIMM Kit

DESCRIPTION:

ValueRAM's KVR533D2E4K2/4G is a kit of two 256M x 72-bit (2GB) DDR2-533 CL4
SDRAM (Synchronous DRAM) ECC memory modules. Total kit capacity is 4GB. The
components on each module include eighteen 128M x 8-bit (16M x 8-bit x 8 Bank) DDR2-533
SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and requires
+1.8V. The electrical and mechanical specifications are as follows:

FEATURES:

Clock Cycle Time (tCK) CL=4 3.75ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 55ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 127.5ns
Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 3.274 W (operating per module)
UL Rating 94 V - 0

Note: The module defined in this data sheet is one of several configurations available under this part number. While
all configurations are compatible, the DRAM combination and/or the module height may vary from what is described
here. However, in no configuration will the module height exceed 1.250" (31.75mm).
