32GB dual-channel DDR5 kit

This 32GB kit contains two 16GB DDR5 modules rated at 4800 MT/s with CL40 latency and a 1.1V operating voltage. It is built as a non-ECC unbuffered DIMM for desktop, workstation, NAS and all-in-one systems. The modules use a standard 288-pin layout and carry JEDEC and RoHS compliance.

DDR5 4800 standard limits

DDR5 at 4800 MT/s defines the baseline JEDEC speed for the generation; the memory controller and motherboard firmware determine whether this rate is reached automatically or requires manual configuration. CL40 is the specified CAS latency at this frequency. The 1.1V voltage is the standard DDR5 level and does not imply overclocking headroom.

Check motherboard DDR5 support

Verify that your desktop or workstation board accepts DDR5 UDIMM modules and lists 4800 MT/s in its qualified vendor list. Confirm the board has at least two DIMM slots free for dual-channel operation. Ensure the BIOS is updated to a version that recognises 16GB density modules at this speed.

Perguntas sobre este artigo

Will these 288-pin modules fit my desktop motherboard?

The kit uses the standard 288-pin UDIMM form factor for DDR5 desktops; check your board manual to confirm it supports DDR5 memory.

Do I need to enable XMP or manually set timings to reach 4800 MT/s?

These modules run at JEDEC-standard 4800 MT/s CL40 1.1 V out of the box, so no XMP profile or manual tuning is required.

Can I add this 32 GB kit to the 16 GB already installed?

Mixing kits with different speeds, latencies or ranks can cause instability; for best results populate all slots with identical modules.
