OWC 8GB DDR4 2933MHz CL21 ECC SODIMM laptop RAM

SKU CH-KYXK-PNW5X

An 8 GB DDR4 ECC SODIMM running at 2933 MHz CL21 with 1.2 V operation for laptops, NAS and micro servers

  • Capacity8GB
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 8GB

  • 8GB capacity lets you run more apps simultaneously
  • 2933MHz DDR4 speed with CL21 latency boosts system responsiveness
  • ECC support detects and corrects memory errors for reliable operation
  • 2V low voltage reduces power draw and heat in laptops
  • Backward compatible with 2666, 2400 and 2133MHz systems

Single 8GB DDR4 ECC module for laptops and NAS

This 260-pin SO-DIMM delivers 8GB of DDR4 memory rated at 2933MHz with CL21 latency. It operates at 1.2V and includes on-die ECC for data integrity in compatible laptops, all-in-one PCs and NAS appliances. The unbuffered design keeps installation straightforward for most systems.

Sustained operation at JEDEC speeds

Rated to PC4-23400 specifications, the module maintains its 2933MHz transfer rate and CL21 timings under continuous load without exceeding the 1.2V envelope. JEDEC compliance means the SPD profiles are recognised by system firmware, so the memory runs at its rated speed without manual tuning. Error correction functions cycle after cycle during long compute or file-serving tasks.

DDR4 SO-DIMM interface limits

The 260-pin DDR4 SO-DIMM form factor fits slots wired for 2133MHz, 2400MHz, 2666MHz or 2933MHz operation; the module will down-clock automatically to the highest speed the platform supports. ECC capability is only active when the CPU and chipset also implement ECC; otherwise the module runs as non-ECC memory. Capacity is fixed at 8GB per module.

Questions about this item

How much power does the 1.2V DDR4 module draw when the laptop runs all day?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw low during continuous use in laptops or NAS systems.

Does my laptop need a 260-pin SO-DIMM slot and DDR4 memory controller to use this 8GB stick?

Yes, it requires a 260-pin DDR4 SO-DIMM slot; the system must support DDR4 ECC unbuffered memory at 2933MHz or lower speeds.

Will this 2933MHz ECC SODIMM downclock properly in my older 2400MHz laptop?

It is backwards compatible and will run at 2666MHz, 2400MHz or 2133MHz to match the system's maximum supported speed.
