2x16 GB DDR5-4400 kit for system upgrades

This Computer Memory Solutions kit contains two 16 GB DDR5 DIMMs rated at 4400 MHz with CL40 timings. The modules are unbuffered, non-ECC and operate at 1.1 V. They use a 288-pin form factor and 2Rx8 organisation. The kit is built with major-brand chipsets and carries a limited lifetime warranty against manufacturing defects.

Ideal for matching pairs in compatible platforms

The kit suits builders who want a matched pair to maximise performance on a platform that supports DDR5-4400 operation. It is not for systems that require ECC or registered memory. It is also not for platforms limited to earlier DDR generations or lower voltage requirements. Mixing with slower modules will cause all memory to run at the lowest common speed.

DDR5-4400 CL40 at 1.1 V decides fit

The decisive specification is the DDR5-4400 speed with CL40 latency at 1.1 V. The motherboard and processor must support this exact data rate and voltage for the kit to run as specified. If the platform caps memory at a lower speed or requires a different voltage, the modules will down-clock or may not operate.

Questions about this item

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

Yes, each 16 GB module uses the standard 288-pin DDR5 DIMM form factor, so it installs in any desktop board with DDR5 slots.

Do I need to enable anything in BIOS for the 4400 MHz speed, and what mistake should I avoid?

Enable the XMP or EXPO profile after seating both sticks; the common error is leaving the board at default speeds so the kit runs slower than 4400 MHz.

If a module fails years from now, what replacement does the manufacturer offer?

Computer Memory Solutions provides a limited lifetime exchange or repair against manufacturing defects, so a faulty stick can be returned for a replacement unit.
