32GB DDR5 4800 desktop module
This is a single 32GB DDR5 4800 CL40 unbuffered UDIMM that runs at 1.1V. It is built for desktop, workstation, NAS and all-in-one systems that accept standard 288-pin DDR5 memory. The module follows JEDEC specifications and contains no ECC or heat spreader.
Tool-free press-in installation
The DIMM seats in a regular 288-pin DDR5 slot with a simple press until the retention clips click. No extra cables, drivers or software are required. The most common issue is inserting the module backwards or not pressing firmly enough on both ends, which leaves the clips unlatched and causes a no-boot condition.
Check motherboard DDR5 support and slot count
Before ordering, confirm that your board or system lists DDR5 4800 (PC5-38400) unbuffered non-ECC UDIMMs on its qualified vendor list. Verify how many 288-pin slots are free and whether the firmware requires a specific population order for single- or dual-channel operation.

Questions about this item
Will this 32 GB DDR5 4800 module fit a standard 288-pin desktop memory slot?
Yes, it uses the 288-pin UDIMM form factor designed for desktop, workstation, NAS and all-in-one systems that accept DDR5 memory.
Does the 1.1 V operating voltage match the JEDEC DDR5 baseline so it runs without manual BIOS voltage changes?
The module operates at the JEDEC-standard 1.1 V, so compatible platforms will configure it automatically at the rated 4800 MT/s CL40 speed.
Is any additional cooling or a heat spreader required for this unbuffered non-ECC DIMM?
The module ships without a heat spreader; JEDEC-compliant 1.1 V operation typically stays within thermal limits for normal desktop workloads.
