4GB DDR3 RAM Memory 1600MHz Memory Module for Desktop PC Desktop PC RAM DDR3 4GB 1600MHz Memory Bank Memory Module Features: ValueRAM's KVR16N11S8K2/8 is a kit of two 512M x 64-bit(4GB) DDR3-1600 CL11 SDRAM (Synchronous DRAM) 1Rx8, memory modules, based on eight 512M x 8-bit FBGA compo-nents per module. Total kit capacity is 8GB. The SPDs are programmed to JEDEC standard latency DDR3-1600 timing of 11-11-11 at 1.5V. Each 240-pin DIMM uses gold contact fingers. EDEC 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 ¡À 1%) On Die Termination using ODT pin Average Refresh Period 7.8us at lower than TCASE 85¡æ, 3.9us at 85¡æ < TCASE < 95¡æ Asynchronous Reset PCB: Height 0.74 inch(18.75mm), single sided component Package list: 1 x 4GB DDR3 Memory RAM Desktop PC
