32GB DDR5 module for OptiPlex towers

This single 32GB DDR5 4800 CL40 UDIMM upgrades compatible Dell OptiPlex 7000 Tower, 7010 SFF Plus, 7010 Tower Plus and XE4 Tower systems. It runs at 1.1V with a 2Rx8 organisation and fits standard 288-pin desktop slots. The module is unbuffered and non-ECC.

JEDEC and RoHS compliance with lifetime warranty

The memory meets JEDEC standard PC5-38400 timings and is RoHS compliant, making it a warranty-safe upgrade that will not void the system manufacturer's coverage. OWC backs it with a limited lifetime warranty and an advanced replacement programme plus free technical support.

32GB capacity in a single rank

One 32GB stick delivers the full capacity in a single slot, leaving other DIMM positions free for future expansion. Buyers who need more than 32GB total or who must populate specific channels in matched pairs should verify their platform's maximum supported memory and slot layout before ordering.

Questions about this item

Does the 2Rx8 rank layout on this 32GB module limit future expansion in the OptiPlex 7000 Tower?

The 2Rx8 organisation is standard for 32GB DDR5 UDIMMs and works within the OptiPlex 7000 Tower memory architecture.

What thermal limit appears first when this DDR5 4800 CL40 kit runs at full load without a heat spreader?

The JEDEC 1.1V operating voltage keeps power draw low, so the module typically stays within its rated temperature envelope under sustained load.

How much power does the 1.1V non-ECC UDIMM draw during continuous all-day operation?

At the standard 1.1V DDR5 voltage the module draws only the power required for 4800 MT/s operation, keeping heat and system power impact minimal.
