KHX1066C5S3K2/4GX
4GB (2GB 256M x 64-Bit x 2 pcs.) DDR3-1066MHz
CL5 204-Pin SODIMM Kit
DESCRIPTION:
Kingston's KHX1066C5D3K2/4GX is a kit of two 256M x 64-bit 2GB (2048MB) DDR3-1066MHz CL5 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 pair has been tested
to run at DDR3-1066MHz at a low latency timing of 5-5-5-15 at 1.5V. The SPDs are programmed to JEDEC standard
latency DDR3-1066MHz timing of 7-7-7 at 1.5V. Each 204-pin SODIMM 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
533MHz fCK for 1066Mb/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) = 6(DDR3-1066)
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
