ASUS ROG STRIX X299-E GAMING II Motherboard

This ATX board uses the Intel X299 chipset and an LGA 2066 socket for Core X-Series processors. It targets enthusiasts and workstation builders who need high core counts and large memory capacity. The board supports up to 256GB of DDR4 memory across eight slots. It is built for multi-GPU configurations and high-speed storage arrays.

Upgrade Path for X299 Platform Users

The board replaces an older X299 model when you need more robust power delivery or additional connectivity. The jump is worth it if your current board limits memory speed or lacks the 2.5G LAN controller. It also adds four USB 3.2 Gen 2 ports at 10Gbps for faster external drives. Builders moving to 9000-series CPUs will find native support here.

Build Integration and Expansion

The layout provides three PCIe 3.0 x16 slots that run at x16, x16/x16, or x16/x16/x8 depending on the CPU. Eight SATA III ports and two M.2 interfaces handle large storage pools. SupremeFX audio with 120dB SNR output and dual headphone amplifiers serves monitoring needs. Intel I219V and Realtek 8125 2.5G LAN handle wired networking.

Questions about this item

What are the ATX dimensions of this board so I can confirm it fits my case?

The board measures 30.5 cm by 24.4 cm, matching the standard ATX form factor for compatible cases

Which CPU power connectors must be seated for the LGA 2066 socket, and what is the common oversight?

Connect both the 8-pin and 4-pin EPS plugs; the extra 4-pin is often missed but required for stable power delivery to Core X-Series processors

What replaceable component on the board maintains BIOS settings when the system is unplugged?

A removable metal battery holder is included; swap the cell when the clock drifts or BIOS defaults reappear after power loss
