ASUS X99-A/USB3.1 LGA 2011-v3 ATX Motherboard

This ASUS X99-A/USB3.1 motherboard uses the Intel X99 chipset and an LGA 2011-v3 socket. It accepts DDR4 memory up to a total of 128 GB. The board follows the standard ATX form factor for typical desktop chassis.

Suits builders upgrading an existing X99 platform

This board fits users who already own a compatible LGA 2011-v3 processor and need a replacement ATX motherboard. It is not for builders starting a new system on a modern socket. It is also not for buyers who require the original retail packaging or a full accessory bundle beyond the included SATA cable and I/O shield.

128 GB maximum DDR4 capacity

The decisive specification is the 128 GB DDR4 memory ceiling. If the intended workload demands more than 128 GB of system memory, this motherboard cannot meet that requirement. For workloads staying within this limit, the board provides the necessary memory headroom.

Questions about this item

Will the LGA 2011-v3 socket need any maintenance or replacement parts over time?

The board ships with a metal battery included; that coin cell is the only user-replaceable component on the motherboard itself.

What limit appears first when the Intel X99 chipset runs sustained workloads?

The chipset supports up to 128GB of DDR4 memory, so total memory capacity is the first hard ceiling you will reach.

How much heat or fan noise does the ATX motherboard produce during all-day operation?

No active cooling is mounted on the chipset, so heat output and noise depend entirely on the CPU cooler and case airflow you provide.
