About this item
Adding a Crucial 16GB DDR4-2666 desktop RAM kit is one of the cheapest ways to make a sluggish office PC or family desktop feel quicker. This new kit (CT2K8G4DFS8266) includes two 8GB PC4-21300 UDIMM sticks, so you can run them in dual channel.
Will DDR4-2666 work in my desktop?
It fits desktop motherboards that take DDR4 UDIMMs, and boards that support faster speeds will typically run it at 2666. It won't fit DDR3, DDR5 or laptop SO-DIMM slots.
- Slots: count your free DIMM slots, since this kit uses two.
- Mixing memory: pairing it with existing sticks of a different speed can slow all of them to the slowest speed.
- Max RAM: check how much memory your motherboard or PC model supports.
- Gaming builds: newer gaming rigs often use faster DDR4, so this kit is better suited to upgrades than high-end builds.
