Z490 Micro ATX motherboard for LGA 1200

The MSI Z490M-S01 is a Micro ATX board built on the Intel Z490 chipset for LGA 1200 processors. It accepts 10th and 11th Generation Core i9, i7, i5 and i3 CPUs. Four DDR4 slots support up to 128 GB of memory in dual-channel mode. The board measures 244 mm by 244 mm.

Suits builders who need overclocking headroom

Enthusiasts who want Z490 features such as CPU and memory overclocking plus 2-way AMD CrossFire support will find the feature set adequate. Users requiring a full-size ATX layout, integrated Wi-Fi, or more than two M.2 slots should consider other form factors.

Maximum memory capacity is 128 GB across four DDR4

This limit defines whether the board can handle the planned workload. The slots run at JEDEC speeds of 2133, 2400, 2666 and 2933 MHz and support XMP profiles up to 4000 MHz and beyond. Populate all four slots with 32 GB modules to reach the ceiling.

Questions about this item

Will the four DDR4 slots need individual stick replacement if one fails?

Each of the four DDR4 slots operates independently, so a single faulty module can be swapped without replacing the others.

What memory speed ceiling appears first when all four slots are populated under sustained load?

With four modules installed the board is rated for 2DPC 2R at 2133, 2666 or 2933 MHz JEDEC, so 2933 MHz is the highest guaranteed speed.

How loud or hot does the chipset area get during all-day operation?

The Intel Z490 chipset is passively cooled; typical sustained workloads keep it within normal operating temperature without adding audible fan noise.
