64GB DDR5 Dual-Channel Kit

This kit provides 64GB of DDR5 desktop memory across two 32GB unbuffered UDIMM modules. It is built for users who need expanded capacity for multitasking, content creation or memory-intensive workloads on DDR5-compatible platforms.

DDR5 4800 PC5-38400 Interface Limits

The modules run at 4800 MT/s with CL40 latency at the standard 1.1V DDR5 voltage. DDR5 architecture splits each module into two independent 32-bit sub-channels, improving bandwidth efficiency over the single 64-bit channel used by DDR4. On-die ECC corrects single-bit errors inside the DRAM array, while the on-module power management IC handles voltage regulation locally for cleaner signal integrity.

Upgrade From DDR4 Or Smaller DDR5 Kits

Moving from a DDR4 system requires a DDR5-capable motherboard and CPU, as the 288-pin DDR5 keying is physically incompatible with DDR4 slots. For systems already on DDR5, this kit replaces lower-capacity modules or slower-speed kits when 64GB of memory is needed for virtual machines, large datasets or heavy multitasking. The jump is worthwhile when the workload exceeds the capacity or bandwidth of the current configuration.

Questions about this item

Should I pick the 64GB kit or a smaller capacity for my DDR5 build?

This kit provides two 32GB modules for a total of 64GB; choose it when your workloads need that much capacity rather than a smaller kit.

What does the 4800MHz speed mean for actual system performance?

The modules run at 4800MT/s with CL40 latency, giving the bandwidth and response times specified for DDR5-4800 operation in a compatible desktop.

How does the DDR5 interface and 288-pin DIMM design affect compatibility?

These are standard DDR5 UDIMMs with 288 pins and 1.1V operation, so they fit any desktop board that officially supports DDR5-4800 memory.
