4GB DDR3L 1866MHz desktop module

This single 4GB DDR3L 1866MHz CL13 1.35V unbuffered DIMM upgrades desktop and workstation systems. It replaces a long list of Crucial part numbers including CT3460760 and CT4397056. The module meets JEDEC and RoHS standards for a warranty-safe installation.

Installation ease and common issues

The 240-pin DIMM fits standard desktop slots and requires no tools beyond opening the case. Align the notch with the slot key and press firmly until the retention clips click. Mismatched speeds or mixing ECC with non-ECC modules can prevent boot or cause instability.

Capacity headroom and limits

Four gigabytes suits everyday office tasks, web browsing and light multitasking. Larger datasets, modern games or virtual machines will exceed this module alone. Adding identical modules expands headroom while maintaining matched timing and voltage.
