Gigabyte GA-MA790FXT-UD5P Motherboard

Introduction and Specs

Gigabyte is a name that most computer enthusiasts will know, as they have had a number of successful motherboards over the years. They consistently produce boards that perform great and are very good overclockers. When you put Gigabyte together with a great overclocking Phenom II X3 CPU, the 790FX northbridge and the SB750 southbridge, you expect to get something good. And we did get something good. That something is called the Gigabyte GA-MA790FXT-UD5P motherboard. It has been a while since we looked at a Gigabyte board, so we were anxious to get a chance to see just what this board could do. First off though, lets look at the specs:

Note (Note 1) Due to Windows Vista/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 2) A JM322 chip supports two SATA 3Gb/s connectors, so the four SATA 3Gb/s connectors are divided into two pairs: GSATA2_0 and GSATA2_1 as one pair and GSATA2_2, GSATA2_3 as another pair.
(Refer to Chapter 2, “Integrated Peripherals” and Chapter 5, “Configuring SATA Hard Drive(s),“ for how to enable the Smart Backup function.)
(Note 3) Whether the CPU/system fan speed control function is supported will depend on the CPU/ system cooler you install.
(Note 4) Available functions in EasyTune may differ by motherboard model.
Remark Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website.
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.
