Capacity and Use

This kit provides 32GB of DDR5 desktop memory in a matched pair of 16GB modules. It is built for desktops, workstations, NAS systems and all-in-one PCs that accept 288-pin unbuffered non-ECC DIMMs.

JEDEC Standard Limits

The modules run at the JEDEC DDR5 4800 baseline with a CAS latency of 40 at 1.1V. They are 100% compliant with the PC5-38400 specification, so they operate within the standard voltage and timing envelope without requiring manual tuning.

Upgrade Path and Value

The kit is a direct replacement for the Kingston KVR48U40BS8K2-32 part number, making it a drop-in upgrade for systems originally shipped with that memory. The jump is worthwhile when the platform supports DDR5 4800 and the user needs more capacity for multitasking or larger workloads.

Questions about this item

Will this kit fit a standard desktop motherboard that takes 288-pin DDR5 UDIMMs?

Yes, each module is a 288-pin unbuffered DIMM built to the JEDEC DDR5 4800 specification, so it installs in any desktop board with DDR5 UDIMM slots.

Can I run these modules at their rated speed without changing voltages in the BIOS?

The kit operates at the JEDEC-standard 1.1 V and CL40 timings, so it will run at 4800 MT/s on any compatible platform without manual voltage adjustments.

Is this memory suitable for a workstation or NAS that requires non-ECC DDR5?

The modules are non-ECC unbuffered DDR5 and are listed as compatible with desktop, workstation, NAS and all-in-one systems that accept standard DDR5 UDIMMs.
