64GB DDR5 4800 Kit

This dual-channel kit provides 64GB of desktop DDR5 memory across two 32GB modules. It targets users building or upgrading a system that needs higher bandwidth than DDR4 for multi-core workloads and gaming. The black UDIMM design fits standard 288-pin DIMM slots.

Best for new DDR5 platforms, not DDR4 boards

The modules suit Intel platforms that support XMP 3.0 profiles and run at 1.1V. Builders staying on DDR4 motherboards or systems requiring ECC should choose a different kit. The 4800 speed and CL40 latency match baseline DDR5 specifications.

Speed and profile: DDR5 4800 with XMP 3.0

The kit operates at 4800MT/s (PC5-38400) with a CAS latency of 40. Intel XMP 3.0 allows the rated speed and timings to be loaded automatically in the BIOS without manual adjustment.

Soalan tentang produk ini

How much heat and power does the 1.10V DDR5 4800 kit draw when running all day?

At 1.10 volts the modules run cooler and use less power than DDR4, while on-module power management keeps thermals steady during extended sessions.

What motherboard slot and BIOS feature are needed for the 288-pin UDIMM kit to work?

A DDR5 desktop motherboard with 288-pin UDIMM slots and Intel XMP 3.0 support is required to run the 64GB kit at its rated 4800MT/s speed.

Will the CL40 DDR5 sticks run alongside older DDR4 modules I already own?

No — DDR5 and DDR4 use different keying and voltages, so the 288-pin DDR5 modules cannot be installed in the same system as DDR4 memory.
