Kingston 8GB (2x 4GB) DDR3 1066MHz SODIMM Memory RAM For APPLE iMac Mac Macbook Pro
KTA-MB1066/4GFR
Description:
Lifetime warranty
Especially for APPLE products
This document describes Kingston ValueRAM?s 512M x 64-bit 4GB (4096MB) DDR3-1066 SDRAM (Synchronous DRAM) memory module, based on sixteen 256M x 8-bit DDR3-1066 FBGA components. The SPD is programmed to JEDEC standard latency 1066Mhz timing of 7-7-7 at 1.5V. This 204-pin SODIMM uses gold contact fingers and requires +1.5V.
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 than TCASE 85?C, 3.9us at 85?C < TCASE ? 95?C
Asynchronous Reset
PCB : Height 1.180? (30.00mm), double sided component
Row Cycle Time (tRCmin) 50.63ns (min.)
Refresh to Active/Refresh 160ns
Command Time (tRFCmin)
Row Active Time (tRASmin) 37.5ns (min.)
Power 1.320 W (operating)
UL Rating 94 V - 0
Normal Operating Temperature 0? C to 85? C
Storage Temperature -55? C to +100? C
