64 GB dual-channel DDR5 kit

This kit supplies two 32 GB unbuffered DDR5 modules rated at 4800 MT/s with CL40 latency. It targets desktop, workstation and all-in-one owners who want a JEDEC-standard upgrade path without overclocking or extra voltage headroom.

1.1 V operation keeps thermals modest

Running at the standard 1.1 V means the modules generate little additional heat and draw minimal power during typical workloads. No heat spreaders are fitted, so case airflow handles cooling quietly without fan-speed changes.

Replaces Crucial CT2K32G48C40U5 directly

The kit matches the Crucial part number specification for capacity, speed, timing and pin-out, making it a drop-in alternative when that SKU is unavailable. The jump is worthwhile when a system needs 64 GB of compliant DDR5 for multitasking, large-file editing or virtualization workloads.

Questions about this item

Will this kit work in a desktop that only has two DDR5 slots?

Yes. The kit contains two 32 GB modules for a total of 64 GB, so it fills both slots and runs in dual-channel mode.

Does the memory require a motherboard that supports 1.1 V DDR5 operation?

Yes. The modules are rated at 1.1 V, which is the standard JEDEC voltage for DDR5 4800.

Is any extra cooling or a heat spreader needed for these sticks?

No. The modules ship without a heat spreader and are designed to operate within JEDEC thermal limits at 4800 MT/s CL40.
