AGI UD128 4GB DDR3 Desktop Memory

The AGI UD128 is a 4GB DDR3 UDIMM module rated for 1600MHz operation with CL11 latency. It targets desktop owners who need a straightforward capacity increase for everyday workloads such as office suites, web browsing and light multitasking.

Build Quality and Connector Details

The module uses a standard 240-pin DDR3 interface that slots directly into compatible desktop motherboards. Rigorously tested chips provide stable operation at the rated PC3 12800 speed, and the low-latency timing supports responsive program switching without extra configuration.

Upgrade Context and Value

This stick replaces older, lower-capacity DDR3 modules or fills an empty slot on a board that still uses the DDR3 platform. The jump is worthwhile when a system feels sluggish with 2GB or less installed memory and the motherboard supports 1600MHz CL11 UDIMMs.

Questions about this item

What does the DDR3 1600 (PC3 12800) rating mean for this module?

The module runs at 1600 MHz with a CAS latency of 11 and is rated PC3 12800, which is the standard DDR3 1600 specification for desktop memory.

What slot and pin count does this 240-pin UDIMM need?

It fits a standard desktop DDR3 DIMM slot with 240 pins; the physical notch position matches the DDR3 key so it only seats one way.

How is the module installed and what step is often missed?

Power off the PC, open the case, align the notch with the slot key, press firmly until both side clips click shut, then verify the capacity shows in BIOS.
