    Tested Details:

    This describes ValueRAM's 512M x 64-bit 4GB (4096MB) DDR3-1333 CL9 SDRAM (Synchronous DRAM)

    memory module, based on sixteen 256M x 8-bit DDR3-1333 FBGA components.

    The SPD is programmed to JEDEC standard latency 1333Mhz timing of 9-9-9 at 1.5V.

    This 240-pin DIMM uses gold contact fingers and requires +1.5V.

    The electrical and mechanical specifications are as follows:

    JEDEC standard 1.5V ± 0.075V Power Supply

    VDDQ = 1.5V ± 0.075V

    667MHz fCK for 1333Mb/sec/pin
