OWC 16GB DDR5 4800 CL40 ECC Unbuffered SODIMM 262-pin 1.1V laptop RAM

SKU CH-VF0N-3PEVE

16 GB DDR5 4800 CL40 ECC unbuffered SODIMM for laptops, all-in-ones and NAS systems at 1.1 V

  • Total capacity16 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems
  • ECC protection guards data integrity in critical workloads
  • DDR5 4800 speed raises bandwidth for demanding applications
  • 1 V operation lowers power draw and heat output
  • 16 GB capacity expands multitasking headroom for laptops and NAS
  • JEDEC-standard design ensures broad compatibility and warranty-safe upgrades

Upgrade Path for DDR5 Laptops and NAS

This 16 GB DDR5 4800 CL40 SODIMM targets laptops, all-in-one PCs and NAS appliances that accept 262-pin ECC unbuffered memory at 1.1 V. It is built to JEDEC and RoHS standards as a direct replacement for Micron parts MTC10C1084S1TC48B and MTC10C1084S1TC48BR.

Buyers Needing Non-ECC or Higher Capacity

The module carries ECC unbuffered firmware, so it suits platforms that require error correction; systems without ECC support will not benefit from the feature. Users who need more than 16 GB per slot, lower latency than CL40 or a heat spreader should evaluate alternative modules.

Single-Density 1Rx8 Organisation Decides Fit

The 1Rx8 layout determines whether the memory controller can address the full 16 GB at 4800 MT/s; verify that your laptop, all-in-one or NAS documentation lists 1Rx8 DDR5 4800 ECC unbuffered SODIMMs before ordering.

Questions about this item

Does the CL40 latency limit throughput during sustained workloads?

CL40 is the rated CAS latency at DDR5 4800 speed; sustained throughput depends on the laptop memory controller and cooling.

How much heat does the 1.1V module generate when running all day?

The module operates at 1.1V without a heat spreader; typical DDR5 SO-DIMM power draw stays low enough for standard laptop airflow.

What must the laptop already support for this 262-pin ECC unbuffered SODIMM to work?

The system needs a DDR5 SO-DIMM slot, a memory controller that accepts ECC unbuffered modules, and BIOS support for 4800 MT/s operation.
