  • 32GB capacity lets you run more apps at once
  • DDR5 4800MHz speed transfers data faster for snappier response
  • CL40 latency keeps timing tight under load
  • 1V operation cuts power draw versus older memory
  • 288-pin UDIMM fits standard desktop DDR5 slots

Single 32 GB DDR5 Module

This 32 GB DDR5 4800 MHz UDIMM adds a full 32 GB of capacity in one 288-pin stick. It runs at the standard 1.10 V and carries a tested CL40 latency. The module is unbuffered and non-ECC, making it a direct drop-in for any desktop board with a DDR5 DIMM slot.

Best for Simple Capacity Upgrades

Builders who need a single large stick to fill one slot or start a new DDR5 system will fit this part. Shoppers looking for dual-channel kits, lower CAS latency, RGB lighting, or a heat spreader should choose a different module.

4800 MT/s DDR5 Speed Rating

The decisive figure is the 4800 MT/s data rate (PC5-38400). If the motherboard and CPU support DDR5-4800 or faster, this module will run at its rated speed; if the platform only runs slower, the stick will down-clock automatically.

Questions about this item

Will this single 32 GB module work in a board that only has two DDR5 slots?

Yes, it occupies one 288-pin DDR5 slot and leaves the second slot free for a future upgrade.

My CPU officially supports 4800 MT/s — will the CL40 timing run automatically?

The module is rated at 4800 MT/s with CL40 at 1.1 V; most DDR5 platforms will apply those settings by default.

Does the lack of a heat spreader affect stability under sustained loads?

DDR5’s on-board power management and 1.1 V operation keep thermals in check for typical desktop workloads without a spreader.
