Rank 1Rx8

  • ECC protection keeps data accurate in server workloads
  • 4800 MT/s DDR5 speed moves data faster through the system
  • 16 GB capacity runs memory-intensive programs simultaneously
  • CL40 latency with 40-39-39 timings gives quick data access
  • 10 V operation lowers power draw and heat output

16 GB DDR5 4800 ECC SODIMM

This 16 GB DDR5 module runs at 4800 MT/s with CL40 timing and on-board ECC. It uses a 262-pin SO-DIMM form factor and operates at 1.10 V. The single-rank 1Rx8 layout is unbuffered and includes an Intel XMP 2.0 profile for automatic configuration.

Suited for notebooks and compact servers

Systems without SO-DIMM slots or without DDR5 memory controllers cannot use this module. Buyers who need registered or buffered DIMMs should look at a different product class.

Unbuffered design with XMP 2.0 profile

The lack of a heat spreader keeps the module low-profile for tight chassis. The XMP 2.0 profile lets the firmware set 4800 MT/s, CL40 and 1.10 V without manual entry. ECC provides single-bit error correction for data integrity.

Questions about this item

Does this 262-pin DDR5 SODIMM require a notebook motherboard with a DDR5 SO-DIMM slot and ECC support?

Yes, the module needs a DDR5 SO-DIMM slot and the system must support ECC unbuffered memory to use the error-correction feature.

Will this CL40 4800 MHz module downclock to match older DDR5 SODIMMs I keep in other slots?

The module runs at 4800 MT/s CL40; if paired with slower DDR5 SODIMMs the system will operate all modules at the lowest common speed and latency.

How can I confirm the 16 GB module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or an OS tool such as dmidecode to verify 4800 MT/s speed, CL40 timings and ECC status.
