X99 AD3 REV3.0 LGA 2011-3 board

The HUANANZHI X99 AD3 REV3.0 is an Intel X99 motherboard built on a 10-layer PCB for LGA 2011-3 processors. It accepts DDR3 memory modules and provides two PCI-E 3.0 16X slots plus two smaller PCI-E slots for expansion cards. Gigabit Ethernet is integrated for wired networking.

283 mm by 215 mm non-standard ATX size

This board measures 283 mm by 215 mm, which is smaller than the standard ATX footprint, so builders must verify that their case mounting points and I/O shield align before purchase. It suits users who need a compact X99 platform with multiple graphics slots and DDR3 support. Those who require a standard ATX layout or integrated graphics should consider a different model.

128 GB DDR3 ECC capacity ceiling

The platform supports up to 128 GB of DDR3 ECC memory across its DIMM slots, setting the practical limit for memory-heavy workloads. Populating all slots with compatible DDR3 ECC modules reaches this ceiling. No other memory generation or non-ECC specification is supported by this chipset implementation.

Questions about this item

How much DDR3 memory can the X99 AD3 REV3.0 actually address?

The board supports up to 128GB of DDR3 ECC or non-ECC memory across its slots.

What PCIe generation do the x16 slots run at and what bandwidth does that cap?

Both x16 slots operate at PCIe 3.0, limiting each to roughly 16 GB/s theoretical bandwidth.

Will this 283mm by 215mm board fit in a standard ATX case?

The board is wider than standard ATX, so verify your case can accommodate 283mm width before installing.
