DESCRIPTION

Kingston’s KHX1333C7D3K3/6GX is a kit of three 256M x

64-bit 2GB (2048MB) DDR3-1333MHz CL7 SDRAM (Syn-

chronous DRAM) memory modules, based on sixteen 128M

x 8-bit DDR3 FBGA components per module. Each module

®

kit supports Intel

capacity is 6GB. Each module pair has been tested to run at

DDR3-1333MHz at a low latency timing of 7-7-7-20 at 1.65V.

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 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 1.180” (30.00mm), double sided component
