8GB DDR4 2400MHz DIMM for Dell systems

This 8GB DDR4-2400 module is built for Dell Inspiron 3668 and OptiPlex 3046 Mini Tower and SFF desktops. It runs at 1.2V with CL17 timing and uses unbuffered non-ECC chips in a 288-pin layout. The single stick adds 8GB of system memory for everyday workloads.

Before ordering check your Dell model

Confirm the system is an Inspiron 3668 or OptiPlex 3046 Mini Tower or SFF. The board accepts two DIMM slots and supports a maximum of 16GB total. Verify an empty 288-pin slot is available and that the existing memory runs at DDR4 2400 speed.

Suits single-stick upgrades not full kits

Buyers adding one module to a compatible Dell desktop will benefit. Builders needing ECC registered memory or speeds above 2400MHz should look elsewhere. Systems already at the 16GB limit or with four populated slots cannot use this stick.

Questions about this item

Does the CM1024642400DIMM come as a single stick or a kit, and do I need anything else to install it?

The package contains one 8GB DDR4 DIMM stick; no extra parts are required for installation in a compatible Dell system.

My Dell OptiPlex 3046 SFF has two slots and a 16GB maximum — should I buy one 8GB module or two?

Each slot accepts up to 8GB, so adding a single 8GB module brings you to 8GB total; add a second identical module later to reach the 16GB limit.

The module is rated DDR4 2400 CL17 — will it actually run at 2400 MHz in my Inspiron 3668?

Yes, the memory operates at 2400 MHz with 17-17-17 timing at 1.2V on the supported Dell platforms.
