AM3 is AMD's big cash cow now and while this CPU isn't really able to compete with the Intel Core i7 on performance, its price point really has a major plus amongst the more budget conscious users, especially in the global financial crisis. Saving as many dollars as you can really means a lot more than it did the same time last year and to this end AMD really has a leg up here.
The other big plus, and this is where I personally really thank AMD, is that they have not just thrown away their older users. AM3 based processors can be run in any AM2+ based board thanks to its dual mode memory controller. AM3 CPU's have a dual channel DDR2 and a dual channel DDR3 memory controller. This means that you can slap one of the newest AMD Phenom II processors in your already setup AM2+ boards and continue to use your existing hardware and later on you an upgrade to an AM3 board with DDR3 and newer technologies and still keep your CPU; it's just that simple and AMD has really thought of everything.
With that said and done, we have already started to look at the various AM3 boards out there. Today's one is an AM3 compatible board while still supporting AM2 processors. That's right, it's a DDR2 offering supporting Phenom II AM3 processors and this one is from GIGABYTE. Designated the MA790GP-UD4H, this board comes in at 129.99 USD from Newegg and has a definite price advantage. How well does it work and what does it have? Let's move on and see.
The Box and What's Inside
Package and Contents
As per usual we start with the package and contents. GIGABYTE has gone with a more universal look to their mainstream boards these days. They are all based on a white background box with the company logo on the front as well as the board model and a few bits of art work.
On the back the top half is pretty generic; it's the same info that is printed on all of the Ultra Durable 3 boards with an explanation of the all solid state components as well as how the new 2 ounce copper layers in the PCB are supposed to work. At the bottom, however, GIGABYTE has decided to put a colour picture of the board and an explanation of the feature set.
GIGAYBTE never skimps on its user manuals or accessories, but unfortunately our images of the accessories somehow got misplaced and corrupted. However, we are happy to report that you get four SATA data cables, an IDE cable, FDD cable and a SATA to Molex power adapter along with the two user manuals and the DVD with Vista and XP drivers and software; a well rounded bundle that is for the mainstream board.
GIGABYTE's boards are extremely impressive; their use of colours is quite attractive and even for the most demanding aesthetics users this board looks fantastic. The board itself is a full sized 30x24cm ATX PCB with six layers of PCB and two layers of copper to help reduce EMI and to remove extra heat from the system.
The 24-pin power connector is sensibly behind the four DDR2 memory slots along with a single green IDE port. The board is equipped with a total of four DDR2 memory slots which are capable of running 1066MHz memory when utilising AM2+ or AM3 processors. The 4/8 pin EPS power connector is located at the top left of the motherboard just behind the PS/2 port towers and just above the heatpipe assembly. This is a much more sensible place as some boards have the 4/8 pin connector between the PS/2 ports and the heatpipe that tends to shred knuckles when or if you ever have to remove the power cables.
The CPU area is extremely clean of any high rise components; in fact, since the use of solid state components, these new components are a great deal smaller. The CPU is given its power through a 5-phase voltage regulation system that also runs through GIGABYTE's DES. The system is cooled by a heatpipe assembly that cools the Mosfets and the 790GX Northbridge, while the SB750 is cooled by an independent heatsink.
Moving along down the right hand side of the board, GIGABYTE has arranged the SATA data ports with four of the six SB750 controlled ports stacked upon each other and rotated 90 degrees. The last two are in the traditional up/down placement just below the other four SATA ports.
Moving along to the rear I/O ports, GIGABYTE has just about everything you will need here. Thanks to the 790GX Northbridge this board has its own IGP powered by the HD Radeon X3300 GPU with a dedicated 128MB of DDR3 Sideport memory, which we will come to explain a bit more about later on.
To that end there are three display ports with a traditional CRT port, a DVI-I port and a HDMI port for connecting to large HD displays such as Full HD TV's. As for the rest they are pretty standard including six stereo audio ports, a single FireWire port with a extra header on the bottom edge of the board, USB ports and a single Toslink S/PDIF-out port.
Lastly on the list we have the expansion slots and the chips that run the additional onboard features. Normally we just cover the slots but to help out a bit we have decided to give a bit more of an explanation of the components used here.
First off, the control chips used for this board are the AMD 790GX Northbridge which is paired to the SB750 Southbridge through a PCIe x4 NB to SB link. The Northbridge is equipped with 20 PCI Express lanes and 16 of them are used for PCIe graphics slots and four are used to connect the Northbridge to the Southbridge. As mentioned before, AMD is integrating graphics into its mainstream chipsets. The 790GX chipset has a HD Radeon X3300 based graphics processor which isn't the most powerful out there but its capabilities are good enough for basic 3D gaming and running Windows. What makes the 790GX a much better option than any of NVIDIA's IGPs is Sideport memory.
AMD has finally listened to the users out there and has setup a memory bus on the IGP to allow a 128MB 400MHz GDDR3 memory chip to be installed. In the BIOS you can configure the graphics system to work in a variety of ways; UMA, Sideport or Sideport+UMA. With Sideport+UMA you can dedicate some system memory to the GPU. If the Sideport memory gets full it will move graphics data into the system memory; a very handy setup to increase the overall 3D performance. Also, the 790GX supports Hybrid Crossfire allowing you to combine the power of the IGP plus a discrete GPU to increase gaming performance, or you can use the IGP to run Physics rendering and use one or two discrete GPU's for graphics rendering; it's really endless.
The board is equipped with two PCI Express x16 slots, one blue and one yellow. Since the 790GX has only 16 lanes for graphics, if you want to run Crossfire it's limited to an 8/8 setup where eight lanes from the blue slot are routed to the yellow slot to give you the balanced setup. Three PCI express x1 slots are also included which run off the SB750's extra six lanes of PCIe connectivity. LAN is handled by a PCIe x1 Realtek Gigabit Ethernet controller and the FireWire is handled by a PCI based Texas Instruments two port FireWire chip. There are no additional SATA or PATA controller chips as AMD still provides IDE support on the SB750 and six SATA ports are deemed enough for this board.
BIOS and Overclocking
GIGABYTE hasn't changed its BIOS for quite some time. Award Modular version 6 is used as normal and all of the overclocking options are located under the Motherboard Intelligent Tweaker(M.I.T) Menu with some other tweaking under the Advanced Chipset Features menu.
Under the M.I.T Menu you can adjust FSB, PCIe and various other bus frequencies along with a quite a few voltage options to help you manage overclocking. One of the best features is that you can overclock the IGP's video core from its default of 700MHz up to 1400MHz.
Under the Advanced Chipset Features menu you can adjust the memory usage for the IGP as well as a few other tweaks.
AMD overclocking is not as refined as Intel when it comes to overclocking. Even Core i7 has a better turn out than AMD. Unfortunately we didn't get past 220MHz; even with all the tweaks and lowering the bus and dividers we still hit a wall at 220MHz. However, we only get a bit of time to tweak and with more time you may get more out of it, but it's nice to be able to get higher speeds straight off the bat, so it's a buyers option here.
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.

Power Usage and Heat Tests
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's power management helps keep the board just below the Sapphire 790GX board.
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 also manages to keep the heat generation down, but not a huge difference between the two boards here.
GIGABYTE's AMD offerings from the beginning have always had plenty of features and kick and while the MA790GP-UD4H isn't going to break any overclocking records, it will give you some extra speed. Combined with its IGP or discrete GPU options and connectivity features, this board is ideal for the budget conscious overclocker or someone who's wanting to build a gaming rig without spending the earth on all of your components.
With a small price tag of just 129 USD over at Newegg it's cheap for what it has and with AMD processors costing a lot less than Intel's offerings at the moment it's extremely worth the consideration.
