HyperX HX318C10F/4 is a 512M x 64-bit (4GB) DDR3-1866 CL10 SDRAM (Synchronous DRAM) 1Rx8 memory module, based on eight 512M x 8-bit DDR3 FBGA components. This module has been tested to run at DDR3-1866 at a low latency timing of 10-11-10 at 1.5V. Additional timing parameters are shown in the PnP Timing Parameters section below. The JEDEC standard electrical and mechanical specifications are as follows:



Features:



??? JEDEC standard 1.5V (1.425V ~1.575V) Power Supply

??? VDDQ = 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

??? 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]
