HyperX HX318LS11IB/4 is a 512M x 64-bit (4GB) DDR3L-1866 CL11 SDRAM (Synchronous DRAM) 1Rx8, low voltage, memory modules, based on eight 512M x 8-bit DDR3 FBGA compo-nents.  This module has been tested to run at DDR3L-1866 at a low latency timing of 11-11-11 at 1.35V or 1.5V. Additional timing parameters are shown in the PnP Timing Parameters section below.
 
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)   933MHz fCK for 1866Mb/sec/pin   8 independent internal bank   Programmable CAS Latency: 13, 11, 10, 9, 8, 7, 6, 5   Programmable Additive Latency: 0, CL - 2, or CL - 1 clock   8-bit pre-fetch

Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm 1%)
  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    On Die Termination using ODT pin
