ASRock Compatible DDR4 Kit

This NEMIX RAM kit provides 32GB of DDR4 memory in a matched pair of 16GB modules. It is built for desktop PCs using ASRock motherboards that accept standard 288‑pin UDIMM modules. The kit runs at 3200MHz with CL22 latency at 1.2V.

Builders with ASRock B450M Boards

The modules are validated for ASRock B450M motherboards and similar platforms that support PC4‑25600 speeds. Systems requiring ECC error correction, registered buffering or DDR5 slots cannot use this kit. Buyers needing heat spreaders or lower latency timings should consider other options.

2Rx8 Dual‑Rank Configuration

Each 16GB stick uses a 2Rx8 organisation, giving the kit a dual‑rank layout that can benefit memory‑controller throughput on compatible boards. Verify that your motherboard supports 2Rx8 modules at 3200MHz before purchasing.

Questions about this item

What comes in the MD25600-628K2 kit and is anything else required?

The package includes two 16 GB DDR4 3200 UDIMM modules for a total of 32 GB. No additional parts are needed; install them into compatible motherboard slots.

Should I choose the 2x16 GB 3200 CL22 kit or a different capacity for my ASRock B450M board?

This 32 GB kit matches the board's DDR4 3200 support and 288-pin UDIMM layout. Select it when you need 32 GB in dual-channel; pick another capacity only if your workload demands more or less memory.

What does the 3200 MT/s rating mean once the kit is installed in my desktop?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20 V. In a compatible system they operate at this speed in dual-channel mode, delivering the rated transfer rate without further configuration.
