DESCRIPTION FEATURES Kingston's KHX2133C11D3W1K2/8GX is a kit of two 512M x 64-bit (4GB) DDR3-2133 CL11 SDRAM (Synchronous * * * * * * * * * JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply * * Bi-directional Differential Data Strobe * * On Die Termination using ODT pin * * Asynchronous Reset DRAM), water cooled, 2Rx8 memory modules, based on sixteen 256M x 8-bit DDR3 FBGA components per module. Each (R) module kit supports Intel XMP (Extreme Memory Profiles). Total kit capacity is 8GB. Each module kit has been tested to run at DDR3-2133 at a low latency timing of 11-12-11 at 1.60V. The SPDs are programmed to JEDEC standard latency DDR31333 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: XMP TIMING PARAMETERS * * * JEDEC: DDR3-1333 CL9-9-9 @1.5V XMP Profile #1: D3-2133 CL11-12-11 @1.60V XMP Profile #2: D3-1600 CL9-9-9 @1.5V VDDQ = 1.5V (1.425V ~ 1.575V) 667MHz fCK for 1333Mb/sec/pin 8 independent internal bank Programmable CAS Latency: 9, 8, 7, 6 Programmable Additive Latency: 0, CL - 2, or CL - 1 clock Programmable CAS Write Latency(CWL) = 7 (DDR3-1333) 8-bit pre-fetch Burst Length: 8 (Interleave without any limit, sequential with starting address "000" only), 4 with tCCD = 4 which does not allow seamless read or write [either on the fly using A12 or MRS] Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm 1%) Average Refresh Period 7.8us at lower than TCASE 85C, 3.9us at 85C < TCASE < 95C PCB : Height 1.88" (48.00mm) w/ heatsink, double sided component Continued >> Document No. 4806388-001.A00 04/25/12 Page 1 continued HyperX MODULE DIMENSIONS MODULE WITH HEAT SPREADER m 0m 8.7342 0.
