Value RAM\'s KVR16R11S4K4/16 is a kit of four 512M x 72-bit(4GB) DDR3-1600 CL11 SDRAM (Synchronous DRAM), registered w/parity, 1Rx4 ECC memory modules, based on eighteen512M x 4-bit FBGA components per module. Total kit capacityis 16GB. The SPD\'s are programmed to JEDEC standardlatency DDR3-1600 timing of 11-11-11 at 1.5V. Each 240-pinDIMM uses gold contact fingers. The electrical and mechanicalspecifications are as followsFEATURES• 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 withstarting address “000” only), 4 with tCCD = 4 which does notallow seamless read or write [either on the fly using A12 orMRS]• Bi-directional Differential Data Strobe• Internal(self) calibration : Internal self calibration through ZQpin (RZQ : 240 ohm ± 1%)• On Die Termination using ODT pin• On-DIMM thermal sensor (Grade B)• 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
