DESCRIPTION FEATURES HyperX HX313C9FB/4 is a 512M x 64-bit (4GB) DDR3-1333 JEDEC standard 1.5V (1.425V ~1.575V) Power Supply CL9 SDRAM (Synchronous DRAM) 1Rx8 memory module, 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 DDR3-1333 at latency timing 667MHz fCK for 1333Mb/sec/pin 9-9-9 at 1.5V. The JEDEC standard electrical and mechanical 8 independent internal bank specifications are as follows: Programmable CAS Latency: 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 85C, 3.9us at 85C < TCASE < 95C Asynchronous Reset Height 1.291 (32.80mm) w/heatsink, single sided component Continued >> kingston.com/hyperx Document No. 4806990-001.B00 04/23/15 Page 1continued HyperX MODULE WITH HEAT SPREADER 7.08 mm 133.35 mm MODULE DIMENSIONS FOR MORE INFORMATION, GO TO WWW.KINGSTON.COM/HYPERX All Kingston products are tested to meet our published specifications.
