Our take on the ASUS Prime X299-A LGA 2066 ATX Motherboard

The ASUS Prime X299-A is an ATX motherboard for Intel's LGA 2066 socket, aimed at Core X-series and Xeon W chips. It offers four DIMM slots for quad-channel memory, three PCIe x16 slots with SLI and CrossFire support, two M.2 slots (one 22110), eight SATA III ports and onboard Wi-Fi 6. It is a workhorse board for content creators and multi-GPU builders rather than a flashy overclocker. Owners like the slot count and stability, but the 3.9 rating reflects complaints about BIOS quirks, VRM heat under heavy loads and a dated platform that newer Intel sockets have replaced.

Pros
  • Quad-channel memory support across four DIMM slots
  • Three PCIe x16 slots with SLI and CrossFire
  • Two M.2 slots, one accepting 22110 drives
  • Eight SATA III ports for large storage arrays
  • Onboard Wi-Fi 6 and USB-C connectivity
  • ATX layout leaves room for big coolers and cards
Cons
  • LGA 2066 is a dead-end socket with no upgrade path
  • VRM can run hot with high-core-count chips under sustained load
  • BIOS and memory compatibility complaints from some owners
  • No integrated graphics, so a discrete GPU is required
  • Older platform lacks PCIe 4.0

What reviewers say

  • 3.9 / 535 ratings

Reviewers and owners describe a solid, feature-rich board for Core X builds, but the average rating is dragged down by BIOS issues and heat. Many praise the storage and expansion options; others report memory training problems and warm VRMs.

What people mention
  • BIOSCriticisedSome owners report confusing BIOS settings and memory kits that fail to train at rated speeds.
  • VRM heatCriticisedHigh-core-count CPUs push the voltage hardware warm under sustained workloads.
  • ExpansionPraisedBuyers value the three x16 slots and dual M.2 for GPUs and fast storage.
  • StoragePraisedEight SATA ports suit owners building large drive arrays.
  • PlatformMixedThe board works well, but LGA 2066 offers no path to newer Intel CPUs.

Questions and answers

Does the ASUS Prime X299-A support overclocking?
Yes. It is built for unlocked Core X chips, with BIOS controls for CPU and memory tuning. High-core-count overclocks push the VRM hard, so airflow over the heatsinks matters.
How many M.2 drives can it take?
Two. One slot accepts 22110-length drives and the other standard 2280 drives. Using both can share lanes with SATA or PCIe slots, so check the manual for your configuration.
Does it have built-in Wi-Fi?
Yes, it includes Wi-Fi 6 (802.11ax) plus an integrated network card for wired Ethernet. No separate Wi-Fi card is needed.
Which CPUs fit this board?
Intel LGA 2066 processors: Core X-series and Xeon W chips. It does not take mainstream LGA 1151 or LGA 1200 CPUs, and there is no upgrade path beyond that generation.
Can I run two graphics cards?
Yes. It supports both SLI and CrossFire across its PCIe x16 slots. Note that few modern games still benefit from multi-GPU setups.
Does it have integrated graphics?
No. The board has no video outputs, so you need a discrete graphics card even though some LGA 2066 CPUs lack integrated graphics anyway.
Where is the ASUS Prime X299-A LGA 2066 ATX Motherboard cheapest?
At Newegg, for $711.95, as of our latest check.
