DESCRIPTION FEATURES HyperX HX321C11T2K2/8 is a kit of two 512M x 64-bit (4GB) JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply DDR3-2133 CL11 SDRAM (Synchronous DRAM), 1Rx8 memory modules, based on eight 512M x 8-bit FBGA VDDQ = 1.5V (1.425V ~ 1.575V) components per module. Each module kit supports Intel 800MHz fCK for 1600Mb/sec/pin XMP (Extreme Memory Profiles). Total kit capacity is 8GB. Each module kit has been tested to run at DDR3-2133 at a 8 independent internal banks low latency timing of 11-12-12 at 1.6V. The SPDs are programmed to JEDEC standard latency DDR3-1600 timing of Programmable CAS latency: 11, 10, 9, 8, 7, 6 11-11-11 at 1.5V. Each 240-pin DIMM uses gold contact Programmable Additive Latency: 0, CL - 2, or CL - 1 clock fingers. The JEDEC standard electrical and mechanical specifications are as follows: 8-bit pre-fetch Burst Length: 8 (interleave without any limit, sequential with starting address 000 only), 4 with tCCD = 4 which does not XMP TIMING PARAMETERS allow seamless read or write (either on the fly using A12 or MRS) JEDEC: DDR3-1600 CL11-11-11 1.5V Bi-directional Differential Data Strobe XMP Profile 1: DDR3-2133 CL11-12-12 1.6V XMP Profile 2: DDR3-1600 CL9-9-9 1.5V 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 2.118 (53.80mm), w/heatsink, single sided component Continued >> kingston.com/hyperx Document No. 4807097-001.B00 04/22/15 Page 1continued HyperX MODULE WITH HEAT SPREADER 8.12 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.
