Computer Memory Solutions CM512642400DIMM 4GB DDR4 2400 CL17 1.2V memory upgrade

4GB DDR4 module for ASUS X99 boards

This 288-pin DIMM delivers 4GB of DDR4 memory at 2400MHz with CL17 timings. It runs at 1.2V without ECC or buffering. The module is validated for ASUS X99-A, X99-A/USB 3.1, X99-DELUXE, X99-PRO/USB 3.1 and X99-S motherboards.

Capacity and headroom

A single stick adds 4GB to systems that support up to 64GB across eight slots. Everyday multitasking and office workloads fit comfortably in this space. Memory-heavy tasks such as large video projects or virtualisation clusters will exhaust the capacity quickly.

DDR4 2400 interface limits

The DDR4 2400 standard caps transfer rates at PC4-19200, so bandwidth cannot scale beyond that ceiling. Latency is fixed at 17-17-17 cycles, limiting responsiveness in latency-sensitive code. The platform tops out at 64GB total, preventing larger memory arrays.
