CAS Latency CL40

  • 32 GB dual-channel kit equips modern desktops with ample memory capacity
  • DDR5 4800 MT/s delivers high data rates for responsive performance
  • CL40 latency supports quick access times in demanding workloads
  • Intel XMP 3.0 profile enables one-click overclocking for enthusiast tuning
  • 10 V operating voltage reduces power draw compared to DDR4

32GB DDR5 kit for desktop builders

This 32GB kit contains two 16GB unbuffered DDR5 modules rated at 4800 MT/s with CL40 latency. It targets system builders and upgraders who need standard-voltage DDR5 memory for modern desktop platforms. The kit operates at 1.10V and uses the 288-pin UDIMM form factor. Intel XMP 3.0 profiles are supported for automatic configuration.

Black UDIMMs with on-module power management

Each module uses a black PCB and the standard 288-pin layout, so installation follows the familiar DIMM slot procedure. DDR5 moves voltage regulation onto the module itself, which simplifies motherboard power design and improves signal integrity. The unbuffered, non-ECC design suits consumer desktop workloads without added register latency.

Replaces DDR4 kits when bandwidth matters

The DDR5 4800 specification delivers roughly 1.5 times the data rate and nearly 2 times the bandwidth of typical DDR4 memory. That jump benefits multi-core CPUs and memory-intensive applications such as content creation or heavy multitasking. The upgrade is worthwhile when the platform supports DDR5 and the workload can use the extra throughput.

Questions about this item

What speed does the DDR5 4800 (PC5 38400) rating deliver in practice?

The kit runs at 4800 MT/s with CL40 timings at 1.10 V, giving the bandwidth shown by the PC5 38400 designation.

Will the 288-pin UDIMM modules fit my motherboard's DIMM slots?

Each 16 GB stick uses the standard 288-pin UDIMM form factor, so it fits any desktop board with DDR5 DIMM slots.

How do I enable the Intel XMP 3.0 profile after installing the memory?

Enter the BIOS, locate the XMP 3.0 setting, select Profile 1, save and reboot; the modules will then run at 4800 MT/s CL40.
