Computer Memory Solutions 4x32GB DDR4 2666MHz CL19 2Rx8 DIMM memory upgrade

System-specific 128 GB DDR4 kit

This four-module kit delivers 128 GB of DDR4 memory using four 32 GB DIMMs. Each module runs at 2666 MHz with a CAS latency of 19 and operates at 1.2 V. The unbuffered, non-ECC design targets desktop and workstation platforms that accept 288-pin DIMMs.

Builders expanding to 128 GB

The kit suits users whose motherboards support four 32 GB unbuffered DIMMs at 2666 MHz and who need the full 128 GB capacity for memory-intensive workloads. Systems limited to lower per-slot densities, platforms that require ECC or registered modules, or builds that cannot address more than 64 GB should look at alternative configurations.

Four-module 128 GB capacity

The single specification that decides fit is the 128 GB total capacity provided by four 32 GB 2Rx8 DIMMs. The motherboard must support this density per slot and the 288-pin DDR4 interface for the kit to function.
