TECHNOLOGY
DESCRIPTION:
Kingston's KHX1866C9D3LK2/4GX is a kit of two 256M x 64-bit 2GB (2048MB) DDR3-1866 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 DDR3-1866 CL9-9-9-27-2T at 1.35V (Profile #1) and DDR3-1600
CL9-9-9-27-2T at 1.25V (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)
