Description

KVR21S15S8/4 4GB 1Rx8 512M x 64-Bit PC4-2133 CL15 260-Pin SODIMM

512M x 64-bit (4GB)

DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8,

non-ECC, memory module, based on eight 512M x 8-bit FBGA

components. The SPD is programmed to JEDEC standard

latency DDR4-2133 timing of 15-15-15 at 1.2V. This 260-pin DIMM uses gold contact fingers.

The electrical and mechanical specifications are as follows:
