Memory Module Specification KVR333S4R25/1G 1GB 128M x 72-Bit DDR333 CL2.5 Registered 184-Pin ECC DIMM DESCRIPTION: This document describes ValueRAM's 128M x 72-bit 1GB (1024MB) DDR333 CL2.5 SDRAM (Synchronous DRAM) "single rank" Registered ECC memory module. The components on this module include eighteen 128M x 4-bit DDR333 SDRAM in FBGA packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) Row Cycle Time (tRC) Refresh Row Cycle Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating 6ns (min.) / 12ns (max.) 60ns (min.) 72ns (min.) 42ns (min.) / 70,000ns (max.) +2.5V (+/- .2V) 6.600 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 1.200" (30.48mm). 5.25 ± 0.005 (133.350 ± 0.13) 0.118 (3.00) 5.171 (131.350) 5.077 (128.950) A B A B 0.100 Min (2.50 Min) (2.30 Min) 0.393 (10.00) 0.78 (19.80) 0.7 (17.80) 1.2 (30.48) 0.0787 R (2.00) (0.157) (4.00) 0.157 Max (3.99 Max) 0.050 ± 0.0039 (1.270 ± 0.10) Figure 1: KVR333S4R25/1G 184-Pin DIMM Part No. VALUERAM0446-001.A00 06/21/05
