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.
