DESCRIPTION

HyperX HX440C19PB3/8 is a 1G x 64-bit (8GB) DDR4-4000
CL19 SDRAM (Synchronous DRAM) 1Rx8, memory module,
based on eight 1G x 8-bit FBGA components per module. Each

module kit supports Intel® Extreme Memory Profiles
(Intel® XMP) 2.0. Each module has been tested to run at
DDR4-4000 at a low latency timing of 19-21-21 at 1.35V. The
SPDs are programmed to JEDEC standard latency
DDR4-2400 timing of 17-17-17 at 1.2V. Each 288-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.
