Memory Module Specification KVR533D2E4/512I 512MB 64M x 72-Bit DDR2-533 CL4 ECC 240-Pin DIMM DESCRIPTION: This document describes ValueRAM's 64M x 72-bit (512MB) DDR2-533 CL4 SDRAM (Synchronous DRAM) ECC "Intel Certified" memory module. The components on this module include nine 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-533 SDRAM in FBGA packages. This 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 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power (IDD0) UL Rating 3.75ns (min.) / 8ns (max.) 55ns (min.) 105ns 40ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 1.620 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 1.250" (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 2.7 55.00 1.270 ± 0.10 4.00 4.00 3.00 2.50±0.20 5.00 0.80±0.05 3.80 2.50 1.50±0.10 Detail A 0.20 1.00 4.00 Detail B Figure 1: KVR533D2E4/512I 240-Pin DIMM Document No. VALUERAM0460-001.A00 09/20/05
