(Item as show inpictures)

DESCRIPTION: Kingston Value RAM's 512M x 72-bit(4GB) DDR3-1600 CL11 SDRAM (Synchronous DRAM) 2Rx8, ECC, Intel® CompatibilityTested, memory module, based on eighteen 256M x 8-bit FBGA components. The SPDis programmed to JEDEC standard latency DDR3-1600 timing of 11-11-11 at 1.5V.This 240-pin DIMM uses gold contact fingers. The electrical and mechanicalspecifications are as follows:

FEATURES •JEDEC standard 1.5V (1.425V ~1.575V) Power Supply •VDDQ = 1.5V (1.425V ~1.575V) • 800MHz fCK for 1600Mb/sec/pin • 8 independent internal bank•Programmable CAS Latency: 11, 10, 9, 8, 7, 6 •Programmable Additive Latency:0, CL - 2, or CL - 1 clock • 8-bit pre-fetch •Burst Length: 8 (Interleavewithout 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 orMRS] •Bi-directional Differential Data Strobe • Internal(self) calibration :Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%) •On DieTermination using ODT pin •On-DIMM thermal sensor (Grade B) •Average RefreshPeriod 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 sidedcomponent.
