Memory Module Specifi cations
KSM26RS8/8HDI
8GB 1Rx8 1G x 72-Bit PC4-2666
CL19 Registered w/Parity 288-Pin DIMM
DESCRIPTION
Kingston's KSM26RS8/8HDI is a 1G x 72-bit (8GB) DDR4-2666
CL19 SDRAM (Synchronous DRAM) registered w/ parity, 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
• VDDQ = 1.2V
• VPP = 2.5V
• VDDSPD = 2.41V to 2.75V
• Functionality and operations comply with the DDR4 SDRAM datasheet
• 16 internal banks
• Bank Grouping is applied, and CAS to CAS latency (tCCD_L, tCCD_S) for
the banks in the same or different bank group accesses are available
• Data transfer rates: PC4-2666, PC4-2400, PC4-2133, PC4-1866, PC4-1600
• Bi-Directional Differential Data Strobe
• 8 bit pre-fetch
• Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop)
• Supports ECC error correction and detection
• On-Die Termination (ODT)
• Temperature sensor with integrated SPD
• This product is in compliance with the RoHS directive.
• Per DRAM Addressability is supported
• Internal Vref DQ level generation is available
• Write CRC is supported at all speed grades
• CA parity (Command/Address Parity) mode is supported
