Memory Module Specifications
KVR18R13D4K4/64
64GB (16GB 2Rx4 2G x 72-Bit x 4 pcs.) PC3-14900
CL13 Registered w/Parity 240-Pin DIMM Kit
DESCRIPTION
ValueRAM's KVR18R13D4K4/64 is a kit of four 2G x 72-bit
(16GB) DDR3-1866 CL13 SDRAM (Synchronous DRAM),
registered w/parity, 2Rx4 ECC memory modules, based on
thirty-six 1G x 4-bit FBGA components per module. Total kit
capcity is 64GB. The SPDs are programmed to JEDEC stan-
dard latency DDR3-1866 timing of 13-13-13 at 1.5V. Each 240-
pin DIMM uses gold contact fingers. The electrical and me-
chanical specifications are as follows:
