Capacity 8GB

Type 288-Pin DDR4 SDRAM

Speed DDR4 2666 (PC4 21300)

  • 8GB capacity adds responsive multitasking headroom for everyday workloads
  • 2666MHz DDR4 speed delivers snappy application loading and smooth gaming
  • CL19 latency keeps data access tight for consistent frame pacing
  • 2V operation cuts power draw by 20% versus DDR3 for cooler running
  • 3mm low-profile height fits compact cases and large CPU coolers

AGI UD138 8GB DDR4 2666MHz UDIMM

This single 8 GB module uses DDR4 technology at 2666 MHz with CL19 latency and 1.2 V operation. It fits standard 288-pin desktop slots and uses Micron memory chips for stable performance. The low-profile height of 31.3 mm helps it fit in tight spaces.

Suits everyday desktop upgrades

Builders who need ECC error correction or registered modules should look elsewhere. Systems limited to DDR3 slots cannot use this memory. Buyers wanting higher frequencies or lower latencies will need different specifications.

8 GB capacity handles common workloads

It provides enough headroom for office applications, web browsing and mainstream gaming at standard settings. Heavy video editing, virtualisation or large dataset work will run out of memory quickly. Adding a second identical module doubles capacity for dual-channel bandwidth.

Questions about this item

What motherboard slot does the 288-pin UDIMM require?

The module fits a standard DDR4 288-pin UDIMM slot on any desktop motherboard that supports DDR4 memory.

Will this DDR4 2666 MHz CL19 stick run with my existing DDR3 memory?

No, DDR4 and DDR3 use different pin layouts and voltages, so they cannot be installed together on the same board.

How can I confirm the UD138 is running at 2666 MHz after installation?

Open Task Manager or BIOS and check the reported memory speed; it should show 2666 MHz with CAS latency 19 at 1.2 V.
