4GB DDR3 1600 Module for Desktop Upgrade

This 4GB DDR3 1600 (PC3-12800) DIMM provides a single memory stick for desktop computers. It operates at CL11 latency as non-ECC unbuffered memory. The 240-pin form factor fits standard desktop slots. Condition is new from bulk packaging.

Best for Single Slot DDR3 Repair

Suits owners of older desktops needing a 4GB replacement or a low-cost capacity addition in a single slot. Builders requiring 8GB or more total capacity, dual-channel kits, ECC error correction, or registered buffering should look elsewhere.

DDR3 1600 CL11 Speed Rating

The module runs at DDR3 1600MHz with a PC3-12800 bandwidth rating and CL11 CAS latency. This timing determines whether the memory matches the motherboard's supported specification for stable operation.

Questions about this item

How do I install this 240-pin DDR3 DIMM and what is the common mistake?

Align the off-centre notch on the module with the slot key, press firmly until both side clips snap shut, and ensure the motherboard supports DDR3 1600 non-ECC unbuffered memory.

What maintenance or replacement will this 4 GB single-rank module need later?

No routine maintenance is required; if errors appear, run a memory test and replace the stick, as individual chips are not serviceable.

What limit appears first under sustained load with CL11 latency at 1600 MHz?

The CAS latency of 11 cycles at 1600 MHz sets the baseline response time, and the single-rank layout may saturate memory bandwidth before temperature becomes an issue.
