  • Total capacity16 GB (2 × 8 GB)
  • Rated speedDDR3 1866 (PC3 14900)
  • 16 GB kit keeps multitasking smooth with two 8 GB modules
  • Dual-voltage 1.5 V / 1.35 V lowers power draw without losing speed
  • 1866 MHz DDR3 rate moves data quickly for everyday workloads
  • PC3-14900 rating confirms JEDEC-standard bandwidth
  • 240-pin unbuffered non-ECC design fits standard desktop DIMM slots

Capacity and voltage

This kit provides 16 GB of desktop memory as two 8 GB modules. It operates at DDR3 1866 with a PC3-14900 rating. The dual-voltage design runs at either 1.5 V or 1.35 V depending on the platform. Non-ECC unbuffered DIMMs suit standard consumer motherboards.

Upgrade path

The modules replace slower DDR3 kits or fill empty slots on boards that support the 1866 speed grade. The jump is worthwhile when the current memory runs at a lower frequency or when total capacity limits multitasking. Systems already running at this speed and capacity will not see a benefit.

Installation notes

Each stick uses the standard 240-pin DDR3 layout and fits the corresponding desktop slot. Alignment of the key notch prevents backward insertion. The most common issue is mixing voltages or speeds across channels, which can stop the system from posting.

Questions about this item

Will the 240-pin DDR3 modules fit my desktop's DIMM slots?

Yes, each 8 GB stick uses the standard 240-pin DDR3 form factor that matches desktop UDIMM slots.

Do I need to change any BIOS voltage setting for the 1.35 V or 1.5 V operation?

The modules are dual-voltage and will run at 1.5 V by default; most boards auto-detect 1.35 V if the platform supports it.

When should I consider replacing these 1866 MHz sticks?

Replace them if memory diagnostics report errors, if the system becomes unstable under load, or when upgrading to a platform that requires a newer DDR generation.
