KHX1800C9D3LK2/4GX

4GB (2GB 256M x 64-Bit x 2 pcs.) DDR3-1800 CL9 240-Pin DIMM Kit

DESCRIPTION:

Kingston's KHX1800C9D3LK2/4GX is a kit of two 256M x 64-bit (2GB) DDR3-1800 CL9 SDRAM (Synchronous DRAM) low voltage memory modules, based on sixteen 128M x 8-bit DDR3 FBGA components per module. Total kit capacity is 4GB. Each module kit supports Intel® XMP (Extreme Memory Profiles). Each module kit has been tested to run at DDR3-1600 CL9-9-9-27 at 1.35V (Profile #1) and DDR3-1800 CL9-9-9-27 at 1.35V

(Profile #2). 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:

FEATURES:

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 then TCASE 85°C, 3.9us at 85°C < TCASE . 95°C Asynchronous Reset

PCB : Height 1.180” (30.00mm), double sided component

PERFORMANCE:

	CL(IDD)	9 cycles

	Row Cycle Time (tRCmin)	49.5ns (min.)

	Refresh to Active/Refresh Command Time (tRFCmin)	110ns

	Row Active Time (tRASmin)	36ns (min.)

	Power (operating per module)	2.160 W (DDR3-1333 @ standard 1.5V)

	UL Rating	94 V - 0

	Operating Temperature	0o C to 85o C

	Storage Temperature	-55o C to +100o C
