Memory Module Specification KVR133X72C2/512 512MB 64M x 72-Bit PC133 CL2 ECC 168-Pin DIMM Module DESCRIPTION: This document describes ValueRAM's 64M x 72-bit (512MB) CL2 SDRAM (Synchronous DRAM) PC133 ECC DIMM module. The components on this module include eighteen 32M x 8-bit (8M x 8-bit x 4 Bank) PC133 SDRAM in TSOP packages. This 168-pin DIMM uses gold contact fingers and requires +3.3V. The electrical and mechanical specifications are as follows: FEATURES: CLK Cycle Time (tCC) Row Cycle Time (tRC) CLK to Output (tSAC) Single Power Supply of Power UL Rating min. = 7.5ns (CAS Latency = 2) / max. = 1000ns 60ns max. = 5.4ns (CAS Latency = 2) +3.3V (+/- .3V) 4.430 W (operating) 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 1.375" (34.92mm).
