ASUS X99-A Intel X99 Motherboard Performance Review


ASUS X99-A Motherboard Review

ASUS X99A Intel X99 Motherboard Layout

The Intel X99 chipset is the current flagship line from Intel, being that it is the flagship the components are typically more expensive. Today I have the opportunity to look at a top tier board that isn’t going to break the bank! The ASUS X99-A Intel X99 motherboard is currently going for only $246.99. At only $246.99 it’s a board that’s packed with features, but not one that is going to break the bank.

ASUS X99-A O.C. Socket

The ASUS X99-A Intel X99 motherboard has many of the features that make ASUS motherboards great. One of the features is the ASUS O.C. Socket. The ASUS O.C. Socket takes advantage of extra pins to connect a proprietary circuit to contacts on the Intel Haswell-E’s LGA (Land Grid Array). When the extra pins are used in conjunction with the ASUS customized UEFI it will allow for higher DDR4 memory frequencies and enhanced stability while overclocking.

Sticking on the topic of the CPU and overclocking, ASUS is taking fine tuning to the next level with the ASUS 5-Way Optimization. The ASUS 5-Way Optimization is able to dynamically change the way your system is performing based on what you’re doing. If you need the CPU performance, you get CPU performance, if you aren’t using a lot of power, the system will optimize itself for power savings.

ASUS 5-Way Optimization

  • Games run swiftly and smoothly with high performance, prioritized bandwidth and vivid sound.
  • Fans stay whisper-quiet for everyday computing and ensure extreme cooling efficiency when gaming.
  • Never-stutter in professional apps and heavy loading.
  • Energy waste is reduced so you’ll save money.


The ASUS X99-A motherboard uses the latest iteration of the ASUS UEFI BIOS. The latest version of the ASUS UEFI BIOS has a few upgrades over the previous versions. The EZ mode of the ASUS UEFI BIOS has the bulk of settings that most people will need. On the EZ mode page the system can be set up with basic settings, set the Intel XMP profile, arrange the system boot order, fine tune the individual fans, and even run the auto-tune to hit an overclock! If there is a need to delve deeper into the system settings, there’s no shortage of those in the Advanced section of the UEFI BIOS.

EZ Mode

  • Fan Profile:
    • Detailed CPU and case fan information for instant cooling!
  • SATA Information:
    • Displays SATA port details for you to easily recognize devices!
  • Fast Clock Adjustment:
    • Use mouse controls to change the time and date!
  • EZ XMP:
    • Improve your DRAM performance with a click!

Advanced Mode

    • Find more info about your graphics cards and slot bandwidth allocation. Great for 2 or 3-way SLI or CrossFireX
  • Shortcut:
    • Press Enter to create shortcuts to favorite settings, or select an existing shortcut and press F4 to go straight there!
  • Quick Notes:
    • Make notes and capture BIOS-related ideas, quickly and conveniently!
  • Last Modified Log:
    • Track last change and save preferred profiles onto a USB drive!
  • SATA Port Renaming:
    • Rename SATA ports for easy identification!

The ASUS X99-A has the latest Fan Xpert 3 built into the board. The Fan Xpert 3 allows for fine tuning each of the fans connected to the motherboard with either 3pin or 4pin cables. Once the fan is plugged into the board, the Fan Xpert 3 scans the fans characteristics and creates custom settings for each one. The settings are dependent on a number of factors, including but not limited to the area hardware thermal sensors where the fan is located. The Fan Xpert 3 is capable of running fans below the rated minimum to keep the noise generated down to an absolute minimum!

This is just a touch of what makes the ASUS X99-A the board that it is! Take a look at the complete specifications below and then we can move on to the good stuff!
