ASRock B450M DDR4 3200 Upgrade

This NEMIX RAM module is an 8 GB DDR4 UDIMM rated at 3200 MT/s with CL22 latency. It is built for desktop PCs using ASRock B450M motherboards that accept standard 288-pin unbuffered memory. The single-rank 1Rx8 stick runs at 1.2 V and uses major-brand DRAM chips.

Builders adding a single stick to a B450M board

It suits anyone expanding an ASRock B450M system with one compatible 8 GB module. Buyers needing ECC error correction, registered buffering, a heat spreader, or a multi-module kit should look elsewhere.

CL22 CAS latency at DDR4 3200

The CL22 timing is the key spec that determines whether this module matches the board’s memory profile. Verify that your ASRock B450M BIOS supports this latency before purchase.

Questions about this item

What DDR4 standard and speed does this module use, and what data rate does that cap at?

This module uses the DDR4 3200 standard, also labelled PC4-25600, which caps the practical data rate at 25 600 MT/s.

What physical slot and pin count does this UDIMM need to fit an ASRock B450M board?

It needs a standard desktop DDR4 DIMM slot with 288 pins; the module is a 288-pin unbuffered UDIMM with no heat spreader.

How is this memory installed, and what step do people often miss?

Power off the PC, open the case, align the notch on the 288-pin module with the slot key, press firmly until both side clips click, then enable the 3200 MT/s profile in the BIOS or it will run at a lower speed.
