DESCRIPTION

Kingston’s KHX1866C9D3T1K2/4GX is a kit of two 256M x 64-bit (2GB) DDR3-1866 CL9 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel capacity is 4GB. Each module kit has been tested to run at DDR3-1866 at a low latency timing of 9-11-9-27 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 ngers and requires +1.5V. The JEDEC standard electrical and mechanical specications are as follows:

XMP (Extreme Memory Proles). Total kit

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: 5,6,7,8,9,10

• 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 y 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/ heatsink, double sided component

• RoHS Compliant
