Built for LGA 2011-v3 workstations

This ASUS X99-M WS motherboard targets builders who need a compact Intel X99 platform for professional workloads. The Micro ATX layout fits smaller chassis while still delivering the chipset’s multi-threaded capability. It suits users upgrading an existing LGA 2011-v3 system or assembling a dedicated render node. Buyers who require newer socket types or higher memory ceilings should look elsewhere.

Maximum memory is 64 GB of DDR4

The single specification that decides fit is the 64 GB DDR4 limit imposed by the X99 chipset and the board’s four DIMM slots. Populate all slots with matching modules to reach the ceiling for memory-heavy applications. If your workflow demands more capacity or a different memory standard, this board cannot meet the requirement.

Thermals noise and power draw in normal use

The board draws modest power for the chipset and voltage regulation under typical multi-core loads. Passive heatsinks on the PCH and VRM zones keep temperatures stable without adding active noise. A standard case airflow path is sufficient; no specialised cooling is mandated by the design.

Questions about this item

What does the 64 GB memory ceiling mean once the board is installed in a Micro ATX case?

The four DDR4 slots can hold up to 64 GB total, so a fully populated system reaches that limit without needing a larger ATX board.

How does the SATA interface limit real-world drive speed on this X99 chipset?

SATA caps sequential throughput at the interface's native rate, so any connected SSD or hard drive will not exceed that ceiling.

What clearance does the LGA 2011-v3 socket area need for a cooler in a Micro ATX chassis?

The socket follows the standard 2011-v3 mounting pattern, so any cooler rated for that layout will fit within the Micro ATX keep-out zone.
