TLDR Review: GIGABYTE Z790 UD AC
Pros
- •Supports Intel 12th and 13th Gen processors for a futurroof platform
- •Excellent overclocking potential with finuned fan speed and temperature control
- •Extensive connectivity with Wi, Bluetooth, USB 3.2 Gen 2x2 Type-C, and multiple additional USB ports
- •Welesigned layout with easy access to ports and slots for both beginners and experienced builders
- •Exceptional value with 16+1+1 phase digital VRM and DDR5 support at a competitive price point

Cons
- •Critical flaw: Ethernet MAC address randomly reverts to 00:00:00:00:00:00 during use, temporarily fixed only by cold boot
- •Ethernet MAC address loss breaks Wakn-LAN functionality that networked builds rely on
- •Manufacturer publicly denies the Ethernet issue exists despite multiple user reports
- •Extremely tight cable clearance around SATA ports makes connections frustratingly difficult
- •BIOS/EFI CSM option constantly reverts to disabled without a discrete graphics card present
- •BIOS settings mysteriously toggle on and off unpredictably
- •BIOS "Tweak" menu lacks important features like NVMe device disabling
- •Some units arrive warped, making proper installation problematic
- •Higitched coil whine reported during operation
- •Quality control standards have significantly declined from Gigabyte's previous reputation
Bottom Line
The Z790 UD AC offers genuinely impressive specs and excellent value at $306.49—with a solid 16+1+1 phase VRM, DDR5 support, and extensive connectivity that makes it attractive for budget-conscious builders looking to pair it with Intel's 13th Gen processors. However, we have to be straight with you: multiple reviewers have encountered a critical Ethernet MAC address bug that Gigabyte refuses to acknowledge, and additional quality control issues including warped boards and coil whine suggest their standards have taken a hit. Unless you're confident you can work around potential Ethernet problems or don't rely on Wake-on-LAN functionality, you might want to carefully weigh these reliability risks against the savings.
