Memory Module Specification KVR667D2N5K2/4G 4GB (2GB 256M x 64-Bit x 2 pcs.) DDR2-667 CL5 240-Pin DIMM Kit DESCRIPTION: ValueRAM's KVR667D2N5K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-667 CL5 SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 4GB (4096MB). The components on each module include sixteen 128M x 8-bit (16M x 8-bit x 8 Bank) DDR2667 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=5 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating 3ns (min.) / 8ns (max.) 54ns (min.) 127.5ns 39ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 2.225 W (operating per module) 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). 133.35 Units : Millimeters (2X)4.00 131.35 10.00 128.95 30.00 (2) 2.50 A 17.80 2.30 SPD B 63.00 4.0 55.00 1.270 ± 0.10 4.00 3.00 2.50±0.20 5.00 4.00 0.80±0.05 3.80 2.50 1.50±0.10 Detail A 0.20 1.00 4.00 Detail B Figure 1: KVR667D2N5K2/4G 240-Pin DIMM Document No. VALUERAM0497-001.A00 06/27/06
