AMD may not have the performance crown when it comes to its processors. In fact, Phenom has a lot of competition from Intel and a long way to go if they want to regain the top crown they stole from Intel quite some time ago.

But while their CPUs aren't top of the line, their chipset business has been spot on. ATI acquisition has allowed AMD to increase its own chipset production to the level where AMD is able to produce platforms for its own products; something that has been a major problem for them in the past. I can remember the Irongate debacle to this day. Now that's a thing of the past thanks to AMD branded chipsets and the 7 series from AMD being top notch.

The first chipset to have come out in the 7 series was the 780G, the first with the next generation in onboard graphics along with HT3 support for the Phenom processors. AMD really outdid themselves; not only was it future proof, it finally introduced a good onboard graphics accelerator. Not to say that it would rival a discrete solution, but its hardware decoding of HD video along with its ability to combine a second ATI graphics card to increase its 3D potential made it a huge success for the cheap PC market.

GIGABYTE has been one of the biggest producers of motherboards along with ASUS and MSI. And one thing is for certain with these three companies; above all else, if the chipset is good, you will find at least one board based on it. Today we are looking at the GIGABYTE GA-MA78GM-S2H motherboard. How does it stack up as a HTPC board? Let's have a good look.

The Motherboard

The Board

GIGABYTE GA-MA78GM-S2H 780G Motherboard

GIGABYTE GA-MA78GM-S2H 780G Motherboard

The board we were shipped didn't come with a retail box, so we skipped our usual look at the package. However, we did get the cables and extras which are standard for a Micro-ATX board, so there's nothing special to note here.

The board itself is based around a 6-layer Micro-ATX motherboard layout. Being so small, layout can be a problem. However, GIGABYTE has managed to keep things relatively neat and tidy and in a case the size of a micro-ATX where airflow is more so restricted, it's very important to keep it all neat and tidy.

The 24-pin power connector along with the single IDE port and FDD connector are located behind the four DDR2 memory slots that the board is equipped with on the right hand edge of the board. The 4-pin power connector is placed behind the PS/2 port towers on the top left of the board. This for any board is an optimal layout as it keeps all of the bulky cables well out of the way.

Five of the six SATA ports that are controlled by the SB700 chipset reside on the bottom right hand edge of the board, well away from any of the major components. While the SB700 supports six SATA ports, GIGABYTE has routed the last one off to a single eSATA port at the rear I/O; good idea GIGABYTE. Another interesting thing that GIGABYTE is now doing for all its boards is including a TPM or Trusted Platform Module connector. This allows for the use of TPM to hardware encode the contents of one's hard disk, preventing unauthorised access to the system. If you're a security nut, GIGABYTE has you covered.

The CPU area, thanks to the retention clamp design AMD uses for its heatsinks keeps the CPU clear of high rise components. This allows for clean installation of heatsinks; no matter how big they are, the clips are easy to get to. The power for the CPU is regulated through a 4-phase solid state component system.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

Moving to the rear I/O ports, GIGABYTE has put a lot into this board, that's for sure. Of note here are the two obvious video ports; one CRT and one DVI-I for standard displays. If you want to go full digital, the HDMI interface port is included as well, allowing easy connection of the system to a LCD or plasma TV; great for HTPC purposes from the IGP. For digital storage, one eSATA port is included that is controlled from the sixth SATA port of the SB700.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

Lastly we have expansion slot possibilities. Thanks to the Hybrid CrossfireX technology, a single PCI Express x16 slot supporting PCI-E 2.0 specs is included. If you have one of the Hybrid CrossfireX certified cards on hand, you can connect it through the PCI-E x16 slot and use both the discrete and IGP together to boost system performance, though don't expect double like standard Crossfire claims, but enough to make some games playable where they normally wouldn't be with the integrated solution alone.

For additional PCI Express connectivity, a single PCI Express x1 slot is included supporting PCI-E 2.0. That's right; SB700 is a PCI-E 2.0 compliant part. Finally, two PCI slots make up the last of the expansion offerings. Two mightn't be much, but remember this is m-ATX. It's not going to have as many as full ATX for obvious reasons, but it's more than enough for a HTPC or basic PC offering.

BIOS and Overclocking

Now we move along to the BIOS and GIGABYTE has gone with its usual Award offering, making it easy to get around just about every GIGABYTE board available. To locate the overclocking options, you simply visit the MB Intelligent Tweaker Menu.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

In the past, most 780G boards haven't let us do much or any overclocking. The GIGABYTE board, however, gave us a little head room. We managed an FSB of 235MHz stable. But this was the limit; all voltages were turned up to get it just at this level.

Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.

Test System Setup and Memory Performance

Test System

Processor: AMD Phenom X4 9850 @ 2.5GHz
Memory: 2x 1GB DDR2-1186 Geil (Supplied by Geil)
Hard Disk: 500GB Western Digital SE16 (Supplied by Western Digital)
Graphics Card: GIGABYTE 9800GX2 (Supplied by GIGABYTE)
Cooling: GIGABYTE 3D Galaxy II (Supplied by GIGABYTE)
Operating System: Microsoft Windows Vista SP1
Drivers: Catalyst 8.6, Forceware 175.16

Today's tests will consist of our ASUS M3A78 board and the GIGABYTE MA78GM motherboards. ASUS' board did not overclock at all in a stable manner, so we are unable to do OC tests with this board. But GIGABYTE did manage an increase as you saw just before, so we threw in the OC tests here.

At stock speeds the two systems were running with DDR2-1066MHz memory, since both boards support this with the Phenom X4 processors. At the GIGABYTE overclocked speeds, we ran with the memory at the same divider.

The CryENGINE 2 comes complete with all of its internal tools and also includes the CryENGINE 2 Sandbox world editing system.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

Crysis is a lot harder on the system. At stock settings, both systems are identical. Only a extra couple of FPS is gained with overclocking.

Power Usage and Heat Tests

Power Consumption

We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

On the power usage scales, both boards are just about on par.

Heat Generation

As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.

GIGABYTE GA-MA78GM-S2H 780G Motherboard

Cooling wise, the GIGABYTE board is a couple of degrees cooler overall.

Final Thoughts

Overall, the 780G chipset is extremely impressive; that much is certain. However, it's usually put into cut-down boards using the Micro-ATX format. While this makes for a great HTPC, some of the potential of the 780G chipset is left unused.

GIGABYTE has done a fantastic job with this board. While it's aimed at the HTPC users and even the office environments, it still has a bit of kick in it in regards to overclocking. While it's not able to push the boundaries like that of Core 2, it's still able to give the AMD platform a kick in the pants and we know that AMD is no where near as easy to overclock as Intel since there are more tweaks needed to get them to run in a stable fashion.

What do TweakTown awards and ratings mean? Click!

Note from Editor: We originally gave an overall score of 80% to this board, but have since come to realise our scores were off the mark and have re-considered both the quality and performance to be superior than first indicated.

This was not influenced in any way, shape or form by outside sources; rather, our own judgement had us feeling that an adjustment to the final rating was deserved.
