Description

Working pull 90 day warranty includes 4 sticks for 16gb total

ValueRAM’s 512M x 72-bit (4GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), registered w/ parity, 2Rx8, ECC memory module, based on eighteen 256M x 8-bit DDR3-1333 FBGA  omponents. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V.This 240-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
