Memory Module Specifi cations
KSM26ES8/8HD
8GB 1Rx8 1G x 72-Bit PC4-2666
CL19 288-Pin DIMM
DESCRIPTION
Kingston's KSM26ES8/8HD is a 1G x 72-bit (8GB) DDR4-2666
CL19 SDRAM (Synchronous DRAM), 1Rx8, ECC, memory module,
based on nine 1G x 8-bit FBGA components. The SPD is
programmed to JEDEC standard latency DDR4-2666 timing of
19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The
electrical and mechanical specifications are as follows:
FEATURES
• Power Supply: VDD = 1.2V Typical
• VDDQ = 1.2V Typical
• VPP = 2.5V Typical
• VDDSPD = 2.2V to 3.6V
• Nominal and dynamic on-die termination (ODT) for
data, strobe, and mask signals
• Low-power auto self refresh (LPASR)
• Data bus inversion (DBI) for data bus
• On-die VREFDQ generation and calibration
