Kingston Ram for Desktop 4GB DDR3 1600/12800

This document describes ValueRAM's 512M x 64-bit (4GB) DDR3-1600 CL11 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 512M x 8-bit FBGA components. The SPD is 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 mechanical specifications are as follows:

• 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 (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 0.740” (18.75mm) or 1.180” (30.00mm)
