Introduction and Specifications

Gigabyte’s MA770T-UD3P is a sub $100 AM3 motherboard with a single x16 PCI-E slot, dual channel DDR3 1666 memory support, and decent overclocking functions. It’s price should entice many budget consumers to look hard at this board for their next upgrade. But, how will it match up against other boards almost double its price?

Gigabyte releases budget-minded AM3 board using AMD’s 770 chipset 

AMD’s 770 chipset seems to have found a home in several vendor’s budget AM3 motherboard offerings. Some of these boards are priced well below $100, which make them ideal for penny-pinching gamers and enthusiasts looking for a quick AM3 upgrade that will give them some great features at a very reasonable price.

However, these motherboards are usually stripped down quite a bit, but they still include most of the basic features to do everything a typical gaming or enthusiast system will do. There’s also some room for expandability in the RAM and processor departments, which should be a consideration for those who need a little bit of head room to make future upgrades to their PCs.

The lowest price we found on an AM3 board based on the AMD 770 chipset was Gigabyte’s MA770T-UD3P, which is what we are evaluating today. Don’t let the price fool you though. There’s plenty of power and features to be had with this $79.99 board. Some of the board’s key features include one PCI-E 2.0 x16 slot, support for dual channel DDR3 1666(OC)/1333/1066 memory, Firewire, and four PCI-E x1 slots.

The MA-770T-UD3P even has some of the advanced features that are typically reserved for mid-range and high-end motherboards. Some of these advanced features include support for RAID, Gigabit LAN, and firewire. There’s also a handy S/PDIF In/Out for high definition audio. This board also comes standard with an advanced 8+2 phase CPU VRM power design for AMD’s 140W processors.

Notes (Note 1) We recommend that you enhance heat dissipation for the CPU VRM area if an AMD Black Edition CPU is installed and the Advanced Clock Calibration is enabled.
(Note 2) Due to Windows® XP 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than 4 GB.
(Note 3) Use of a CPU that supports ECC is required if you wish to install ECC memory.
(Note 4) Whether the CPU/ system fan speed control function is supported will depend on the CPU/ system cooler you installed.
(Note 5) Available functions in EasyTune may differ by motherboard model.
  1. Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors’ website or 3rd party website.
  2. Due to most hardware/software vendors no longer offer support for Win9X/ME. If some vendors still has Win9X/ME drivers available, we will publish on website.
