64GB DDR5-4800 Quad-Channel Kit

This 64GB kit contains four 16GB DDR5-4800 unbuffered DIMMs rated at CL40 and 1.1V. It targets desktop builders and integrators who need a matched set for quad-channel platforms or high-capacity dual-channel systems. The 288-pin modules use major-brand components and ship new from Computer Memory Solutions.

Suited for matched-pair installs.

The kit works best when installed in matched pairs so the memory controller can run all modules at the rated 4800MT/s speed. Systems that demand ECC error correction or registered buffering cannot use these unbuffered non-ECC sticks. Builders who need single modules or different densities should select another part.

2Rx8 organisation decides compatibility

Each 16GB module is built as a dual-rank 2Rx8 device, which determines how the memory controller addresses the chips. A platform that only supports single-rank x8 or x16 populations will not recognise the full capacity. Verify the motherboard or CPU specification for 2Rx8 support before purchase.

Questions about this item

Will the 288-pin DDR5 DIMMs fit my motherboard's DDR5 slots?

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

What is the correct way to populate the four sticks, and what common mistake should I avoid?

Install the kit in matched pairs as the manufacturer recommends; a frequent error is mixing these 4800 MHz CL40 modules with slower or faster memory, which forces the entire system to run at the lowest common speed.

When might a module need to be replaced under the lifetime warranty?

If a stick develops a manufacturing defect, Computer Memory Solutions will exchange or repair it for the life of the product; no scheduled maintenance is required for the memory itself.
