HX318C9SR/4

4GB (4GB 512M x 64-Bit) DDR3-1866 CL9 240-Pin DIMM

SPECIFICATIONS

DESCRIPTION

HyperX HX318C9SR/4 is a 512M x 64-bit (4GB) DDR3-1866 CL9 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 512M x 8-bit FBGA components per module.

Each module supports Intel® XMP (Extreme Memory Profiles). Each module has been tested to run at DDR3-1866 at a low latency timing of 9-10-11 at 1.5V. The SPDs are programmed to JEDEC standard latency DDR3-1600 timing of 11-11-11 at 1.5V. Each 240-pin DIMM uses gold contact fingers. The JEDEC standard electrical and mechanical specifications are as follows:

CL(IDD) Row Cycle Time (tRCmin) Refresh to Active/Refresh

Command Time (tRFCmin) Row Active Time (tRASmin) Maximum Operating Power UL Rating Operating Temperature Storage Temperature

*Power will vary depending on the SDRAM used.

• 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°Cº

• Asynchronous Reset

• Height 1.311” (33.30mm), w/heatsink, single sided component
