Targeted Upgrade for NEC PC Mate

This 4 GB DDR4 module is built specifically for NEC PC Mate J Type MA and ML series desktops. It matches the exact speed, timing and voltage those systems expect so installation is straightforward. Buyers needing ECC or registered memory should look elsewhere.

Thermals and Power

Operating at 1.2 V without a heat spreader keeps power draw low and eliminates extra height clearance issues. The unbuffered design runs quietly in standard office chassis with typical airflow. No additional cooling is required for normal workloads.

Deciding Specification

The 288-pin DDR4 2400 CL17 2Rx8 configuration is the single factor that determines fit; the board must accept non-ECC unbuffered DIMMs at this speed and rank. Systems limited to lower speeds or different pin counts cannot use this module.

Questions about this item

How do I install this 288-pin DDR4 DIMM in my NEC PC Mate and what step is often missed?

Power off, unplug, open the case, align the notch on the 288-pin DDR4 module with the slot key, press firmly until both retention clips click; the step often missed is fully seating both ends so the clips engage automatically.

What maintenance or replacement will this 4GB DDR4 2400MHz CL17 module need over time?

No routine maintenance is required; if a fault appears, the manufacturer offers a limited lifetime exchange or repair against manufacturing defects when purchased directly from Computer Memory Solutions.

What limit appears first when this unbuffered non-ECC DDR4 runs sustained workloads?

The system maximum of 8GB across two sockets is the first limit; with this single 4GB stick you can add one more 4GB module before reaching the platform capacity ceiling.
