HX321C11SRK2/8
8GB (4GB 512M x 64-Bit x 2 pcs.)
DDR3-2133 CL11 240-Pin DIMM Kit
SPECIFICATIONS
DESCRIPTION
HyperX HX321C11SRK2/8 is a kit of two 512M x 64-bit (4GB)
DDR3-2133 CL11 SDRAM (Synchronous DRAM) 1Rx8,
memory module, based on eight 512M x 8-bit FBGA
components per module. Each module kit supports Intel®
XMP (Extreme Memory Profiles). Total kit capacity is 8GB.
Each module has been tested to run at DDR3-2133 at a low
latency timing of 11-12-12 at 1.6V. The SPDs are
programmed to JEDEC standard latency DDR3-1600
timing of 11-11-11 at 1.5V. Each 240-pin DIMM uses gold
contact fingers. The JEDEC standard electrical and
mechanical specifications are as follows:
