Kingston's KHX2133C9AD3X2K2/4GX is a kit of two 256M x 64-bit 2GB (2048MB) DDR3-2133MHz CL9 SDRAM
(Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR3 FBGA components per module. Each
module kit supports Intel

 XMP (Extreme Memory Profiles). Total kit capacity is 4GB. Each module kit has been tested

to run at DDR3-2133MHz at a low latency timing of 9-11-9 at 1.65V. The SPDs are programmed to JEDEC standard
latency DDR3-1333MHz timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V.
The JEDEC standard 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

8 independent internal bank

Programmable CAS Latency: 6,7,8,9

Posted CAS

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]

Bi-directional Differential Data Strobe

Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%)

On Die Termination using ODT pin

Average Refresh Period 7.8us at lower than TCASE 85°C, 3.9us at 85°C < TCASE < 95°C
