The fastest, easiest and most affordable way to improve your computer's performance and speed is with a simple memory upgrade. A memory upgrade will optimize your computer's performance and speed so you can load applications in seconds, multitask with ease and improve battery life. We ensure high-quality and reliability by thoroughly testing every component with intense workloads and real-world applications, far beyond the industry standard. ValueRAM's 1G x 64-bit (8GB) DDR3L-1600 CL11 SDRAM (Synchronous DRAM), 2Rx8, low voltage, memory module, based on sixteen 512M x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1600 timing of 11-11-11 at 1.35V or 1.5V. This 204-pin SODIMM uses gold contact fingers. The electrical and mechanical specifications are as follows: FEATURES JEDEC standard 1.35V (1.28V ~ 1.45V) and 1.5V (1.425V ~ 1.575V) Power Supply VDDQ = 1.35V (1.28V ~ 1.45V) and 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 1.18” (30mm), double sided component
