Pro Overclocking DDR5 kit

This 32 GB dual-channel kit delivers DDR5 6400 speed at CL38 latency and 1.35 V. Two 16 GB unbuffered modules carry Intel XMP 3.0 and AMD EXPO profiles for automatic configuration. A white aluminium heat spreader keeps temperatures in check during heavy workloads.

Gamers and builders seeking high frequency

The combination of 6400 MT/s data rate and low CAS 38 suits systems that benefit from fast memory throughput. Users who need ECC error correction or registered modules should select a different product line.

Speed grade decides compatibility

The DDR5 6400 (PC5 51200) rating is the single specification that determines whether this kit matches your motherboard and CPU memory controller. Verify that your platform supports this exact data rate before purchase.

Questions about this item

Does this 32GB kit require a motherboard that supports DDR5 6400 with Intel XMP 3.0 or AMD EXPO profiles?

Yes, the modules are rated for DDR5 6400 CL38 at 1.35V and include both Intel XMP 3.0 and AMD EXPO profiles, so a compatible motherboard BIOS is needed to reach the rated speed.

Will the white aluminum heat spreader fit under a large CPU air cooler?

The kit uses a low-profile aluminum heat spreader in white; clearance depends on your specific cooler, so check the cooler’s RAM-height specification before installing.

Is this memory unbuffered non-ECC and suitable for a standard desktop build?

Correct, it is an unbuffered, non-ECC dual-channel kit designed for consumer desktop platforms.
