This review is from: Gigabyte Socket AM2+/AMD 770/DDR2/A&2GbE/ATX Motherboard GA-MA770-UD3 (Personal Computers)

Product Specs are plentiful. I originally purchased this because of the MB Intelligent Tweaker(M.I.T.)in BIOS in suppport of the Quad Phenom II X4 940 Black Edition 3.0GHz and up to DDR2 1200 MHz memory modules and the Ultra Durable 3 technology. Currently running CPU at 3.4+ GHz w/ no voltage increase and no heat problems using AMD supplied H/S and fan. I normally buy ASUS boards for their excellent quality MOBO and crash free bios recovery.

I initially had some problems OC CPU and DDR2 1066MHz RAM. Updated the BIOS for current CPU ID updates. After update, OC proved to be easy and very stable. One word of note, most DDR2 1066MHz RAM, in my case (Corsair Dominator PC2-8500C5D 4GB Dual Channel)does not default at that speed, you have to overclock RAM or set in BIOS to reach that speed. JDEC specs auto default is 800MHz. EPP (enhanced performance profile)specs needs to be set/enabled, to unclock the 1066MHz speed. I kept trying to set multiplier, voltage, and timings w/o enabling the EPP specs mode in BIOS. Settings would never hold and PC would constantly BSOD. Finally after reviewing specs via the Easy Tune 6 window interface tweaker from Gigabyte and CPU-Z ID, I recognized the EPP feature that needed to be enabled. Set timings according to Corsair aggressive specs and PC is flying now with room for expansion. If you increase the FSB freq, this will increase memory speed over 1066 MHz. But doing this will introduce more heat in the system. MOBO have proven to be very reliable, runs cooler than other MOBOs, solid build. I think I just became a Gigabyte fan.

My build:
Cooler Master Centurion 590 ATX Mid Tower Case Black
CORSAIR 750w TX Series 80 Plus Certified Power Supply
(2)Western Digital Caviar Black 500 GB Bulk/OEM Hard Drive 3.5 Inch, 32 MB Cache, 7200 RPM SATA II WD5001AALS
Lite-On 22X DVDrw-saw Sata Retail B/w
Corsair TWIN2X4096-8500C5D Dominator 4GB 2 X 2GB PC2-8500 1066MHz 240-Pin DDR2 CL5 Dual Channel
EVGA 512-P3-N973-TR 512MB GeForce 9800 GT DDR3 PCI-Express 2.0 Graphics Card
AMD Phenom II X4 940 Black Edition 3.0GHz Cache 8MB AM2+ 125W Processor - Retail
Windows Vista Ultimate with SP1 Upgrade 64 Bit OS
and of course the Gigabyte GA-MA770-UD3 (rev. 1.0) MOBO

Highly recommended. Will look to build a micro-atx small factor PC for my next project. Gigabyte will be first on my list.

Post comments: Make sure you check the Gigabyte approved memory support list for compatibility. The Corsair Dominator was not compatible with this mobo. Ordered the Kingston Hyper-X.

I upgraded my MB since my MSI fan started to make noise and finally cracked !!! This is a very friendly and wonderful MB. Keep cool temperatures all the time with "normal" office and photowork - no games - Works great with my AMD 64x2 5200 processor. Recommended product.
