DESCRIPTION
Kingston's KHX1600C9D3K4/8GX is a kit of four 256M x 64-bit
(2GB) DDR3-1600 CL9 SDRAM (Synchronous DRAM) 1Rx8
memory modules, based on eight 256M x 8-bit DDR3 FBGA
components per module. Each module kit supports Intel
(Extreme Memory Profiles). Total kit capacity is 8GB. Each
module kit has been tested to run at DDR3-1600 at a low
latency timing of 9-9-9-27 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 fingers and requires
+1.5V. The JEDEC standard electrical and mechanical specifications are as follows:

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]

• 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 1.180” (30.00mm), single sided component
