Memory Module Speci cations KVR18R13S4/8 8GB 1Rx4 1G x 72-Bit PC3-14900 CL13 Registered w/Parity 240-Pin DIMM DESCRIPTION SPECIFICATIONS This document describes ValueRAM s 1G x 72-bit (8GB) DDR3- CL(IDD) 13 cycles 1866 CL13 SDRAM (Synchronous DRAM), registered w/parity, Row Cycle Time (tRCmin) 47.125ns (min.) 1Rx4 ECC memory module, based on eighteen 1G x 4-bit Refresh to Active/Refresh 260ns (min.) FBGA components. The SPD is programmed to JEDEC stan- Command Time (tRFCmin) dard latency DDR3-1866 timing of 13-13-13 at 1.5V. This 240- Row Active Time (tRASmin) 34ns (min.) pin DIMM uses gold contact fingers.
