8 GB DDR4-2400 DIMM for Dell systems

This 8 GB unbuffered DIMM runs at 2400 MHz and 1.20 V, using the 288-pin DDR4 form factor. It is built for desktop PCs, workstations and servers that accept PC4-19200 memory. The module is validated for a range of Dell OptiPlex, Precision, XPS, Alienware, Vostro and PowerEdge models listed by the manufacturer.

Suits owners of listed Dell platforms needing

Buyers with non-Dell motherboards should verify DDR4-2400 support and 288-pin compatibility before purchasing. Systems that require registered or ECC memory cannot use this unbuffered module. Machines limited to lower memory speeds will not run this stick at its rated frequency.

The single deciding specification is DDR4-2400

Only boards and platforms that explicitly support this speed and voltage will operate the module correctly. If the target system specifies a different DDR generation or a different data rate, this DIMM will not fit or function.
