Kingston Technology 4GB DDR3 240-pin DIMM Kit KHX1333C9D3UK2/4GX Data Sheet

4GB (2GB 256M x 64-Bit x 2 pcs.)
DDR3U-1333 CL9 240-Pin DIMM Kit

Kingston's KHX1333C9D3UK2/4GX is a kit of two 256M x 64-bit

(2GB) DDR3U-1333 CL9 SDRAM (Synchronous DRAM), 1Rx8,

ultra low voltage, memory modules, based on eight 256M x 8-

bit  FBGA components per module. Each module kit supports

 XMP (Extreme Memory Profiles). Total kit capacity is

4GB. Each module kit has been tested to run at DDR3U-1333

at a latency timing of 9-9-9-27 at 1.25V. The SPDs are pro-

grammed to JEDEC standard latency DDR3-1333 timing of

9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers.

The JEDEC standard electrical and mechanical specifications

are as follows:

CL(IDD)

9 cycles

Row Cycle Time (tRCmin)

49.5ns (min.)

Refresh to Active/Refresh

160ns (min.)

Command Time (tRFCmin)
