    HyperX 64GB (8x8GB) 2800MHz DDR4 CL14 DIMM Memory Product Description

    HyperX 64GB (8x8GB) 2800MHz DDR4 CL14 DIMM Memory

    HyperX HX428C14SBK8/64 is a kit of eight 1G x 64-bit (8GB) DDR4-2800 CL14 SDRAM (Synchronous DRAM) 2Rx8, memory modules, based on sixteen 512M x 8-bit FBGA components per module. Total kit capacity is 64GB. Each module supports Intel® XMP (Extreme Memory Profiles). Each module has been tested to run at DDR4-2800 at a low latency timing of 14-15-15 at 1.35V. The SPDs are programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The JEDEC standard electrical and mechanical specifications are as follows:

    JEDEC: DDR4-2133 CL15-15-15 @1.2V
    XMP Profile #1: DDR4-2800 CL14-15-15 @1.35V
    XMP Profile #2: DDR4-2666 CL14-14-14 @1.35V

    CL(IDD) 15 cycles
    Row Cycle Time (tRCmin) 46.5ns (min.)
    Refresh to Active/Refresh Command Time (tRFCmin)  260ns (min.)
    Row Active Time (tRASmin) 33ns (min.)
    Maximum Operating Power TBD W*
    UL Rating 94 V - 0
    Operating Temperature 0oC to +85oC
    Storage Temperature -55oC to +100oC

    *Power will vary depending on the SDRAM used.

    Power Supply: VDD = 1.2V Typical
