DESCRIPTION

Kingston's KHX1866C9AD3T1K3/6GX is a kit of three 256M x 64-bit (2GB) DDR3-1866 CL9 SDRAM (Synchronous DRAM) 1Rx8 memory modules, based on eight 256M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel® XMP (Extreme Memory Profiles). Total kit capacity is 6GB. Each module kit has been tested to run at DDR3-1866 at a low latency timing of 9-11-9 at 1.65V. The SPDs are programmed 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:

XMP TIMING PARAMETERS

• JEDEC: DDR3-1333 CL9-9-9 @1.5V

• XMP Profile #1: D3-1600 CL9-9-9 @1.65V

• XMP Profile #2: D3-1866 CL9-11-9 @1.65V

FEATURES

• JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply

• VDDQ = 1.5V (1.425V ~ 1.575V)

• 667MHz fCK for 1333Mb/sec/pin

• 8 independent internal bank

• Programmable CAS Latency: 9, 8, 7, 6

• 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

• Asynchronous Reset

• PCB : Height 2.401” (61.00mm) w/ heat spreader,

single sided component
