MSI is one of the giants within the PC hardware industry. They have been around for as long as I can remember. Motherboards is one of the ground stones in their business but the company have diversified into many different areas the last couple of years and as you may know, MSI is now one of the top suppliers of laptops.

Today I am going to review a very interesting motherboard from MSI, the NF750-G55. Here are the specifications:

By the specifications of the NF750-G55 it's easy to conclude that MSI has worked hard to produce something a little extra with this board. The board offers support for SLI, Hybrid SLI and has some interesting proprietary technologies of MSI, like the “Easy OC Switch”. In this review I will not test the SLI functionality since it's been done before, instead I will focus on the integrated GeForce 8200 chip and see what it can produce in terms of performance.


The NF750-G55 comes in a rather sober looking cardboard box of standard size. On it, MSI emphasizes the support of the latest AMD processors, the support for SLI and Hybrid SLI and some of the extra features like the True Blu-ray Audio, APS and Easy OC Switch.

The included accessories are: a manual; a quick start installation guide; a drivers and utilities CD; the I/O back panel plate; SATA and IDE cables and a SATA power converter cable.


Although the MSI NF750-G55 is of the ATX standard, it's a little narrower than most other ATX boards.

There are 4 memory slots which supports up to 16GB of DDR3 (up to 1600MHz). To clarify a little here, the chipset officially only supports up to 1333MHz, but it's possible to run the memories at 1600MHz by doing a small change to the multiplier in the BIOS.

The only heatsink on the motherboard is the heatsink located on the nForce 750a SLI circuit.

The CPU cooler is fastened with screws which I think is great since it allows you to really get a grip of how tight the cooler is fastened, much better than with plastic anchorage systems. The 4 pin connector for the CPU is located in the middle of the board.

The MSI Active Phase Switching (APS) is located to the right of the 12V ATX connector. This system is in charge of real time automatic regulation of the power feeded to the CPU. The power level is actually illustrated by 4 LEDs which is a nice extra feature.

The board has two PCI-E x16 ports and 1 PCI port. As you can see; the PCI-E ports are separated by quite a big distance. If you use a double slot card in the second PCI-E port you will not be able to use the PCI port at all. It would have been better to place the PCI port before the first PCI-E x16 port.

The internal connectivity also incorporates 5 SATA 2 ports with RAID functionality, 3 USB 2.0 ports, a COM port connector, connectors for external audio; digital S/PDIF and a CD contact.

The integrated chips for the sound and the Ethernet connectivity are the Realtek ALC889 and RTL45CL. Both chips are of high quality and supported with excellent drivers. The Fintek chip located next to the battery is in charge of the general I/O functions of the motherboard and also makes it possible to control fans with the popular SpeedFan program.

Perhaps the most interesting feature of this motherboard is the “Easy OC Switch”. It consists of a pink switch as you can see from the image below. This switch allows us to increase the FSB of up to 35% without having to do any other changes. In principle this addition is excellent, but it will only work well if the processor you are using supports overclocking without needing an increase of the voltage.

The back panel connectivity is excellent; check the specifications above for a complete list.

Here are a couple of screenshots of the hardware I used:

In the graphics test I used a resolution of 1024×800 with the highest graphics settings.


The BIOS on this board comes from AMI (American Megatrends Inc) and is very intuitive and easy to handle when overclocking.

The menu that interested me the most was of course the Cell Menu where all the real important settings are, at least of you want to overclock your system. Even though the NF750-G55 can be considered a medium range motherboard it offers many possibilities for overclocking both the CPU and the memory modules.

The M-Flash program which is incorporated in this BIOS is actually unique to MSI motherboards. It's a smart little program which lets us update the BIOS and even to backup and recover old BIOS versions.

There is also a menu called “User Settings”. It makes it possible to setup different “profiles” of the BIOS setting. This can come in handy if you want to quickly load a preset of overclocking settings for a gaming session or similar.


The CPU performance of the nForce 750a chip is within the margins that I had hoped for. However the memory testing came out a little short which surprised me as this is normally a strong area with the NVIDIA chips.


The read and write speeds of the HD were very good which means that NVIDIA have solved the driver issues which have caused the hard disk to work slower than it should on older chipsets.


What draw my attention of the above results were the poor results from the WinRAR test. My conclusion is that it must be due to the memory problem noted above.

In the test of the IGP GeForce 8200 chip I didn't receive any remarkable results in the 3D testing so it's easy to conclude that you shouldn't use it for gaming. It did work just fine for playback of HD videos though.

The power usage of this system is really low, especially when it's operating in idle mode which makes it a good choice if you are building a 24/7 system.


NVIDIA has made classic AMD overclocking chipsets in the past including the now almost mythical nForce 2 and nForce 4 platforms. So what about the nForce 750a SLI overclocking capabilities? The following screenshots says it all:

I was able to overclock the FSB to 264MHz (!) which was actually a bit surprising to me, I hadn't expected it to be so “overclock friendly” being a medium range card.

I also tried to overclock the integrated graphics card (GeForce 8200). I managed to get it to run stable at 601/1442MHz for the core and shaders respectively.


My first experience with the NF750 chipset has been a pleasure. The MSI NF750-G55 is a very diverse motherboard. It can be used in a hardcore SLI high end system or it can be used as a base plate for a HTPC project thanks to the integrated VGA with HDMI output.

Generally, MSI has managed to build a great motherboard around the nForce 750a SLI chipset. Its performance and overclocking abilities are excellent as the same goes for its connectivity. The integrated graphics solution is good but not as powerful as some of the integrated chips that AMD/ATI offers.
