Compatible Dell OptiPlex DDR5 upgrade

This OWC module adds 8GB of DDR5 4800 memory to Dell OptiPlex 7000 Tower, 7010 SFF Plus, 7010 Tower Plus and XE4 Tower systems. It uses a 288-pin UDIMM form factor with CL40 latency and 1.1V operation. The single-rank 1Rx16 design meets JEDEC standards for a warranty-safe installation. No heat spreader is fitted.

Suits owners of listed OptiPlex models wanting

Buyers with other desktops, laptops or workstations should verify their platform accepts DDR5 4800 UDIMMs before purchasing. Systems requiring ECC or registered memory cannot use this non-ECC unbuffered module. The 8GB capacity may limit users running heavy virtualisation or large creative workloads.

Fits a standard DDR5 DIMM slot on supported

Installation frees no additional slots beyond the one occupied. The module draws power directly from the slot at 1.1V with no extra cabling needed. It replaces Dell part numbers AB883073 and SNP29NJ4C/8G for direct compatibility. Ensure the system BIOS recognises the new capacity after fitting.

Questions about this item

Will my OptiPlex 7000 Tower need any other parts before I install this 288-pin 1.1V DDR5 UDIMM?

No extra parts are required; the module fits the standard DDR5 UDIMM slot and runs at the JEDEC 1.1V level used by the OptiPlex 7000 Tower, 7010 SFF Plus, 7010 Tower Plus and XE4 Tower.

How will this CL40 4800 MHz DDR5 module behave alongside any existing DDR5 memory I keep in the same OptiPlex?

The system will run all installed DDR5 modules at the lowest common speed and latency; this stick is rated CL40 at 4800 MHz, so faster modules will down-clock to match.

How can I confirm the module is recognised at 4800 MHz CL40 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 4800 MHz, CL40 timing and 8 GB capacity for the new DIMM.
