Excellent overclocker! All solid caps.
Great unlocking and overclocking board! This board is virtually identical to the MA-785GM-S2H DDR2 version, and I can confirm that it overclocks and unlocks just as well. Runs G.Skill DDR3-1600 perfectly with various processors (tried multiple chips: Sempron 140, Athlon II X2 250, and Phenom X2 550BE).

Experience: 2 Weeks

- SO MUCH value in this board for only 85$!
- Onboard VGA/DVI/HDMI
- Very stylish board that doesn't take a lot of space.
- 2oz copper?
- Seems to have pretty good overclocking features in the bios.
- Seriously I don't think there's any, even at a price targeted for value.
I bought this to upgrade the Pentium 4 crappy computer of the mom of my GF. I couldn't believe how cheap it was to make her computer at least 10x faster. I've used 2x1Gb OCZ DDR3 40$ and AMD X2 250 at 70$.

Great mobo, excellent price. Many features.
No Sideport memory for Radeon HD 4200 graphics.
This is an excellent motherboard. It's Gigabyte, so quality bas always. Its got every port you can imagine. 6 USB PS/2, eSATA, FW 400, 10/100/100 ethernet, everything. Still have legacy support for IDE and Floppy so that good.

785G and the Radeon HD 4200 rock. While not the best for gaming, its got to be the best chipset for HTPC users. 1080p is flawless and with Flash 10.1 installed, Flash becomes a non-issue. YouTube 1080p is perfect with no frames dropped.

Runs all current AM3 processors and will probably support Thuban Phenom II X6 processors in the future. Has Advanced Clock Calibration to unlock Phenom II X2 550/555 to Deneb quad-core Phenom II X4s. Overclocking capabilities are decent. Got 3.2GHz Athlon II X4 stable on stock voltage.

- Attractive price
- All around great IGP for web surfing, office work, occasional old game
- Excellent feature set: HDMI, DVI, VGA, eSATA, FireWire, etc.
- Has AMD's SB710/750 southbridge; great for unlocking disabled cores.
- Nice color scheme
- 8 pin EPS connector, all solid capacitors help reinforce good power to the board.
- No heatsinks on MOSFETs on side of CPU socket
- HD Audio header in an awkward location
A great budget/HTPC board with a great price.

One of the biggest bang for buck motherboards I've seen - it offers a bit of everything. A great array of back inputs make this board especially stand out in comparison to the competition.

IGP Performance is very good. 1080p Youtube videos play flawlessly on my Samsung 24" 1080p monitor.

I would have liked to see as small flat aluminum heatsink on the chokes and MOSFETs to the side of the CPU, but it probably runs cool enough to not need the extra cooling.

Unlocking features are present on this motherboard as it has the SB710/750 southbridge which supports Advanced Clock Calibration - All I had to change in the BIOS to unlock was ACC Enabled; Hybrid EC Firmware, and voila, I have a perfectly functional quad core CPU with a slight bit extra voltage added. Tested for 12 hours Prime95, and everything was in the green.

Would recommend and purchase this board again.

Experience: 6 Months
I found it excellent to play with... OVERCLOCK MY PHENOM II X3 TO A QUAD CORE...
it was pretty new ...there a was something like a wouldn;t boot first time but second time but motherboard update  fix it all..
overall excellent board.contain mostly what most people need... hdmi and dvi ...dolby audio...can't get wrong...

All in one motherboard, great for start up HTPC or budget systems
Uses newer DDR3 ram so theoretically can move to another board later on without having to buy new ram
Solid capacitors which from seeing older MBs go through mushroom capacitors is a good thing if you want to keep the board long term
Not really a gaming board with on board video (but its not really advertised as such, just an FYI)
Only 1 PS2 legacy connector in the back (has to be either a PS2 keyboard or PS2 mouse but not both if you are worried about using your older equipment)
Can't really say if there is a weakness to this MB
Both for a surf and word computer and it works perfectly for it. Would even work as a make shift HTPC since it does have built in HDMI outputs.

As we were minimizing the cost for a new computer, we needed to use the old keyboard and mouse from the previous computer but was only able to use 1 of them as there was only 1 PS2 legacy connector in the back, be warned of this in case you didn't read it in the tech specs. Other than that, it was really to put into the case, solid capacitors are great for long term health of the board, would have been nice to have the SATA connectors in an angle instead of sitting straight up so for longer video cards it might be a problem getting to them.

Awesome value
loads of features
This is like the ultimate HTPC board.. m-atx 4 ddr3 slots hdmi video ext sata and firewire loads of bios options...there's not another board out there that has all these features together and anywhere close to this price ...popped in an athlon x4 620 and 4gb of ddr3 and a blue ray drive and wow the video output on this seems loads better compared to my old 8600gts even handles WoW 1280x720 at high settings thanks Gigabyte!

-Good Price
-Quality pcb with 2oz copper.
-Can easily unlock phenom 2 550 x2 cpu to x4
-DDR 3 and AM3
none so far
For under $200 you have an excellent high quality MB and the ability to turn a dual core 550 to quad core as well as decent on board video capability. At this price you just can't go wrong. Just add your ram, and if you need more power for gaming a decent video card and your good to go.

Nice BIOS options.
USB issue
I like any mainboard that allows voltage to be lowered and not just raised. I wish all motherboard makers did that. The only issue I have is that both boards will occasionally shut down upon insertion of a USB device. It's not an electrical issue with the case or power supply cause they are in differnt cases with different supplies.

High Quality
Plenty of options in BIOS
O.C. able
Good color scheme for windowed geeks like myself
loads of connectors and outputs.
Large vidcard may block 1 of the 2 pci slot but who cares. That's why it's mATX.
Would and probably will buy another of these. Maybe even another for a gift system. Runs nice and tight. After struggling over a cratered RAM module this thing booted up no problem at all and is solid so far. Have to love the 2oz. copper layer. Bios is pretty good with loads of options.
Would/will buy again.

Comment: Bjorn3D review: The MA785GMT-UD2H is a nice board, with enough ports and features to satisfy budget buyers. Gigabyte goes a step further by pairing the board with the Realtek ALC889A codec to give it support for Dolby Home Theater through S/PDIF. AHCI support is a question mark.
