With AMD still some way off a new motherboard platform release motherboard vendors are limited to just revamping old designs with new features, such as we saw Gigabyte do recently with the 990FXA-UD7. Their latest updates are being allocated to the mid-range 990FXA-UD3 AMD motherboard and these updates take it to revision 4.0. The major changes include a refreshed CPU VRM design with Gigabyte’s digital power engine and a 10 phase VRM. 
Furthermore the components used on this motherboard include newer and better chokes, capacitors, and MOSFETs as well as upgraded chipset and VRM heatsinks. Additionally Gigabyte have added their newest version of the UEFI setup program to the 990FXA-UD3 Rev 4.0.
Other than those changes the 990FX-UD3 is still the same core motherboard designed to support AM3+ Vishera (Piledriver and Bulldozer) CPUs as well as older AM3 CPUs from the Phenom II X2/4/6 and Athlon II X2/3/4 series. There is support for 64GB of dual channel 2133MHz memory and two PCIe 2.0 X16 slots as well as two PCIe 2.0 X4 slots that are both X16 physical. Two PCIe 2.0 X1 slots and a legacy PCI top off the rest of the PCI(e) expansion. There are 6 SATA III 6Gbps ports from the SB950 Southbridge and two eSATA 6Gbps ports from a Marvell controller. There are four USB 3.0 ports (Etron EJ168 powered), 8 channel Realtek ALC889 audio and Realtek 8111F ethernet. Pricing will match that of the older SKU at $140.
