DESCRIPTION FEATURES HyperX HX318C10FR/4 is a 512M x 64-bit (4GB) DDR3-1866 CL10 SDRAM (Synchronous DRAM) 1Rx8 memory module, • JEDEC standard 1.5V (1.425V ~1.575V) Power Supply • VDDQ = 1.5V (1.425V ~ 1.575V) based on eight 512M x 8-bit DDR3 FBGA components. This module has been tested to run at DDR3-1866 at a low latency • 933MHz fCK for 1866Mb/sec/pin timing of 10-11-10 at 1.5V. Additional timing parameters are shown in the PnP Timing Parameters section below. The • 8 independent internal bank JEDEC standard electrical and mechanical specifications are as follows: • Programmable CAS Latency: 13, 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 • Height 1.291” (32.80mm) w/heatsink, single sided component Note: The PnP feature offers a range of speed and timing options to support the widest variety of processors and chipsets. Your maximum speed will be determined by your BIOS.
