ASRock has been one of the up and comers in the motherboard market. Originally slated to be an OEM only producer, ASRock found that just building plain boring boards may make you a few bucks, but mainstream users are now wanting more and more on their systems and are turning more towards high-end and enthusiast boards. To this end the ASRock company has started to put a lot of investment into producing new and more impressive boards.
ASRock has a lot of Intel boards now, but equally they have supported AMD just as much and today we have a new board for the AM3 based processors using DDR3 memory and powered by AMD's mainstream 790GX chipset, which has a lot of goodies in itself such as an IGP for budget users.
ASRock has positioned this board at the cheap end of the mainstream boards, coming in with a light price tag of 114.99 USD over at Newegg which makes it one of the cheapest ATX 790GX boards out there.
The Box and What's Inside
Package and Contents
ASRock has packed the M3A790GXH-128M in a rather attractive box. The theme is red in colour which we can only assume is to compliment the ATI part since AMD has gone all green. On the front ASRock has some nice artwork along with the model number and product support info.
On the back ASRock simply has a plethora of award logos that they have won for their past motherboards along with very basic info on AMD's Overdrive with ACC setup; nothing really specific to the board itself.
ASRock supplies a single user manual which isn't as thick as most, but it does cover the major setup and functions of the board as well as some basic software setup and information. Two separate CD's are included, one containing drivers and software for XP and XP-64 and the other containing drivers and software for Vista and Vista-64. A single DVD would have been a better more logical option, however.
Included in the accessories are four SATA data cables, a single Molex to SATA power converter, IDE cable and FDD cable with a rear I/O shield.
Coming to the board itself now, ASRock uses a blue 6 layer PCB; not quite as bright blue as the GIGABYTE PCB, but still nice to have a bit of a different design now and then. The board is a full ATX design and follows the perfect layout with the 24-pin ATX power connector behind the four memory slots and the 4/8 pin power connector at the top left of the board just behind the PS/2 ports.
Progressing down the right hand edge of the board, the single IDE port controlled by the SB750 chip is located just below the memory slots on a horizontal axis, making it a bit of nightmare if you have a large graphics card to be installed and need to use the IDE port. It's not impossible, but it's a routing nightmare.
On the very bottom of the board are the SATA ports. There are five red ports and a orange port. All six ports are controlled by the SB750, but if you want to use the eSATA port on the rear of the board you need to bridge a cable from the orange port to another orange SATA port at the back of the rear I/O shield.
ASRock has kept the CPU area clean of high rise components, so those who want to use large aftermarket heatsinks can do so without worries. The CPU is given a 5 phase voltage regulation system which is comprised of all solid state capacitors and Iron Ferrite Chokes, giving it a cleaner voltage signal for overclocking as well as reducing leak current and reduction in heat generation.
The rear I/O ports are pretty well standard; we have three video out ports for the IGP which are CRT, DVI-I and HDMI. S/PDIF audio is handled through the Toslink audio port and analogue 7.1 audio through the six analogue ports. You can clearly see the eSATA port on the rear and the orange bridge port if you want to use it. It's not a switch over job; it's a manual setup.
Speaking of manual setups, ASRock doesn't make it any easier to setup Crossfire. Rather than digital switches to steal 8 lanes from the first PCIe x16 slot, you are given a paddle card like what was first used with the nForce 4 and SLI setups. The very same technique is needed here; one way gives you 16 lanes to the top x16 slot and one lane to the lower x16 slot and in the other direction you have eight lanes per slot. A third red x16 slot is provided which is x4 electrically and run off the SB750's four spare lanes with a single x1 slot at the top of the board and two PCI slots making up the compliment of expansion slots.
BIOS and Overclocking
ASRock uses the same designed BIOS as ASUS does; we call it the tab BIOS as it's a different setup to the straight down menus of the traditional Award BIOS setup. If you're an ASUS user you will know how to navigate; it's not that hard.
Under the Advanced menu there are several sub menus; the overclocking takes place in the CPU Configuration menu.
Under the CPU Configuration menu you can adjust FSB, PCIe clocks, memory ratios, HT Link ratios and speeds as well as various voltages.
It was a definite surprise to us that ASRock managed to pump out 240MHz FSB stable where SAPPHIRE's board stumbled when going above 220MHz. This was only a crude overclock; 245MHz became unstable, but with more time, voltages and some more tweaking we could possibly get 250+MHz out of this board considering how easy it went to 240MHz.
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.

On the chopping block today we have the ASRock M3A790GXH-128M against our baseline board, the Sapphire PURE 790GX which is our default for 790GX chipset comparison. Our tests again were done at stock and overclocked specs; here we will see if any advantage is given to the ASRock board with a 20MHz higher bus clock.

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.
Both Sapphire and ASRock run a pretty matched setup when it comes to power consumption.
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.
Sapphire runs a bit cooler thanks to a slightly better cooling setup on its voltage regulators.
ASRock sure are surprising us with newer and better boards from a relatively new comer to overclocking. Sure, they have had a few boards now and then that handle a respectable level of overclocking, but their latest generation of mainstream boards really show some promise, especially in this field. Some of the high-end boards have trouble making 240MHz FSB, but with a few small tweaks 240MHz was stable and with more time I am sure you could get a lot more out of it.
Not only does it overclock, it's also packed with plenty for your gaming PC needs including Hybrid Crossfire support when using selected Radeon cards as well as a really attractive price tag, just hitting the 115 USD mark and it really is the ultimate AMD board for the price.
