Gigabyte dropped off their GA-MA785GPMT-UD2H motherboard today that is based on the AMD 785G/SB710 chipsets. This is a chipset that we have had our sights set on for long time now as it addresses the lack of multi-channel LPCM audio out lacking in the 690G/780G/790GX chipsets along with other video playback enhancements. The additional bonus with this chipset is improved integrated graphics performance and full support for the AM3 processors. In fact, we just found the perfect home for our new AMD Phenom II X3 705e processor.

In early testing, this board has performed superbly, so much so, that we will be running it around the clock to get a performance preview up for you this weekend. Sorry about the short post and lack of pictures tonight, but we need to complete testing before showing the board off properly. In the meantime, we have a couple of early photo shots for your viewing pleasure. We will be back shortly with our initial thoughts on the chipset and why Gigabyte's particular board design has already impressed us.






7/12 Update - We need to discuss a couple of items with AMD on Monday morning concerning the beta driver set we received before publishing preliminary results. Gigabyte has done a masterful job with the 785G/SB710 chipsets on this board. However, the early video drivers are generating a few strange results in HD playback and PCMark Vantage. We also believe our Sims3 game scores are a bit low based on the new hardware although they are better than the 780G.

Perfect! by Spoelie, 213 days ago
Seems like the board I'm looking for
*AM3, support all recent cpus
*decent integrated graphics suitable for htpc
*µATX sized
*Hits all the I/O ports for a modern computer
*Not a budget design!!
Strangely the first board I see that hits all these points.

Will probably use this to upgrade a lot of my families' (non-enthousiasts') computers, if the review doesn't come with big caveats anyway :)

and here are 2 more points which need to be met get me "on board"

* pricing
* overclockability

RE: Perfect! by juampavalverde, 213 days ago
no ofense, but i got an asus m3a78-em from past year, and has everything u said (780g+sb700), even the sata are better placed for long video cards, the only thing i dislike is that u cant use displayport and peg link at same time (yeah it as displayport output onboard...) and other things due to the older chipset and implementation, no sideport ram, no acc on sb700. but it can deal with am2+/am3 up to 140w. anyway this gigabyte its quite nice.. only if they have put angled at the edge those sata ports...

Don't forget:

2 fugly and outmoded IDE ports
A heatsink that completely blocks the PCI-e x1 port.

RE: Perfect! by dingetje, 212 days ago
wow I hadn't noticed the blocking heatsink...what WERE they thinking! :/

RE: Perfect! by Mr Perfect, 212 days ago
I think that white connector is for a floppy drive, it looks shorter then the green one.

RE: Perfect! by squeezee, 211 days ago
I wonder if the 1X port is actually blocked or if this is simply a matter of perspective. The heatsink is obviously designed so that the 1x slot would clear it, could be misaligned by 1-2mm or so.

RE: Perfect! by Swalchy, 211 days ago
No, it's definitely blocked. They've done the same thing with the GA-MA790FXT-UD5P - http://www.giga-byte.com/Products/Mothe.../Products_Overview.aspx?ProductID=3005

RE: Perfect! by rhog, 211 days ago
NO it is NOT Blocked the heatsink is Cut Low on the side where the 1X PCI_epress port is located. I own a number of board that use this heatsink and I have not had a problem placing a 1X card in the Slot.

RE: Perfect! by Myrandex, 210 days ago
I agree not blocked. I have a gigabyte 780G Micro ATX board with a similar heatsink design, and I use an Intel GB Ethernet Adapter, which fits fine. There isn't any low hanging dingleberries on the card that touch the heatsink, it is designed just right for a PCIe 1x card.

Are you going to take pictures of the BIOS? by Ryun, 213 days ago
Of the AMD based chipset Gigabyte boards I've seen I haven't been too impressed with the BIOS options. You can't seem to lower the voltage on anything (for instance, with the RAM you can only increase the voltage in positive increments so <=1.8v DDR2 runs at 1.9) and it just seems really messy.

some questions by dolcolax, 213 days ago
1) can it undervolt?
2) can it unlock cores?

one thing i hate about amd gigabyte boards is the placement of the heatsink retention and the ram slots. A big heatsink will probably hit 2 ram slots in this board.

Potential intsallation issues... by The0ne, 213 days ago
1. Big fans might not fit due to the location of the DIMM sockets
2. Big video cards might not fit due to the DIMMS and "Gigabyte" blue heatsink.

AM2 Cpus by cghebert, 212 days ago
Gary, do you know if this will work with older socket AM2 Athlon X2s?

Looking forward to the review.

RE: AM2 Cpus by cghebert, 212 days ago
To answer my own question, according to Gigabyte's website for the GA-MA785GPM-UD2H, it should support them.

RE: AM2 Cpus by jajig, 212 days ago
That's the wrong motherboard. The one in your link is the AM2+ DDR2, the board being previewed is AM3 DDR3. The Gigabyte GA-MA785GPMT-UD2H does not support older CPUs.

Reply
RE: AM2 Cpus by cghebert, 212 days ago
Thanks for the clarification. Gary doesn't say anywhere in the preview that it is AM3, but in one of the pictures you can make out DDR3 near the memory slots. Hopefully the only difference will be AM3 and DDR3 vs. AM2,AM2+ and DDR2. If so, I'll be going with the older socket and memory style.

RE: AM2 Cpus by ET, 212 days ago
Thanks for the link. Although it's not the same motherboard, it's the AM2+ version of it, and I'd assume that most of the review would be applicable to it. From Gary's first comments it sounds like this could be a good board for non-enthusiasts, as Spoelie said. AMD has good CPU's at the low end, and coupled with a well specced board with good integrated graphics it could be a winner.

Looking great! by Sake, 212 days ago
This board will probably be powering my HTPC too (AM3, mATX, LPCM audio, internal 1394 connector) and I will certainly read the review.

For now I'm wondering:
- will Scythe Mini Ninja fit?
- will the eSATA connection be powered?

Bad heatsink placement. by yyrkoon, 212 days ago
It is unfortunate that Gigabyte placed the (Northbridge?) chipset heat sink right in the way of the only PCI-E 1x slot. I for one, would/could have a use for it, since I prefer Intel GbE NiCs, I would would want to put one there. I would assume though, if it is there, it *must* be usable. Good placement for a reverse ATX design case, which I also happen to own. Well, I guess that could be considered subjective, but I prefer any other cards around my video cards to be under, rather than over. It may trap some heat in some cases, but mine happens to have a side venting 120mm fan there :)

However I would like to point out to those who have commented already on this; After market heatsinks are still a possibility. Especially if the price is at or under $100. Also, the cooling is all passive it seems, which is a plus on several fronts.

bad layout by haplo602, 211 days ago
- PCIe x1 slot blocked by chipset heatsink
- dimm slots too close to CPU socket/HSF retention frame

so not a board for me ...

Reply
RE: bad layout by Myrandex, 210 days ago
Unintelligence?

The PCIe 1x slot isn't blocked. PCIe 1x cards (at least the ones I'm familiar with, including the one I'm using in my Giga-byte board with a similar design) fit just fine. They go ON TOP OF the heatsink, where in the picture it is clearly cut away to allow the cards to pass. Dimm slots being blocked don't matter to me either, as my CPU heatsink & fan isn't a huge monstrosity which causes close DIMMs to be a problem. It isn't stock, but it still isn't bad.

Awkward SATA placements by loimlo, 211 days ago
Long VGA card would block almost three valuable SATA ports on Giga's 780/785G boards! Please! Somebody to get Gigabyte to fix the awkward SATA placements. Even their own budget model, 740G, is better than 780G/785G's in this regard.

What about NB heating ? by NoobyDoo, 210 days ago
Let us know if the NB heats up as much as the 780G does. 780G gets really hot.

this weekend? by dingetje, 210 days ago
"we will be running it around the clock to get a performance preview up for you this weekend"

so....you meant next weekend?

or will it be like the promise you made about the ASRock A780GMH/128M review that never happened:
