64GB DDR5 4800 Kit for Desktops
This OWC kit supplies 64GB of DDR5 memory in four 16GB unbuffered UDIMMs. The modules run at 4800MT/s with CL40 latency at the standard 1.1V JEDEC voltage. They are built for desktop, workstation, NAS and all-in-one systems that accept 288-pin DDR5 DIMMs.
Suits JEDEC DDR5 platforms.
The kit fits systems requiring non-ECC unbuffered DDR5 at the base 4800 speed. It will not work in motherboards that demand ECC, registered modules, or a different DDR generation. Buyers needing error correction or registered signalling should select a different product line.
4800MT/s CL40 at 1.1V JEDEC standard
The decisive specification is the JEDEC-standard 4800MT/s data rate with CL40 timings at 1.1V. If your platform requires a higher validated speed, lower latency, or a different voltage, this kit will not meet that requirement.

Questions about this item
Will this 64GB kit work in my desktop that has four DDR5 slots?
The kit contains four 16GB DDR5 4800 CL40 1.1V unbuffered non-ECC UDIMMs, totalling 64GB. Each module is a 288-pin DDR5 DIMM, so it fits standard desktop DDR5 slots.
Do I need to enable XMP or change BIOS settings to reach 4800 MT/s?
The modules are JEDEC-standard DDR5 4800 CL40 at 1.1V, so they run at the rated speed without XMP or manual voltage changes.
Can I mix these modules with my existing DDR5 memory?
Mixing is possible only if the existing memory is also DDR5 4800 CL40 1.1V unbuffered non-ECC UDIMM; otherwise the system will default to the lowest common speed and timing.
