MSI is one of the giants within the PC hardware industry. They have been around for as long as I can remember. Motherboards are one of the cornerstones of your business, but the company has diversified into many different areas in recent years, and as you may know, MSI is now one of the leading providers of laptops.

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

Based on the specifications of the NF750-G55, it is easy to conclude that MSI has worked hard to produce something a little more with this board. The board offers support for SLI, Hybrid SLI and has some interesting proprietary technologies from MSI, such as the “Easy OC Switch”. In this review, I will not test the SLI functionality as it has 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 fairly understated-looking standard-size cardboard box. In it, MSI emphasizes the support of the latest AMD processors, the support for SLI and Hybrid SLI and some of the additional features like True Blu-ray Audio, APS and Easy OC Switch.

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


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

There are 4 memory slots that support up to 16GB of DDR3 (up to 1600MHz). To clarify a bit here, the chipset officially only supports up to 1333MHz, but it is possible to run the memories at 1600MHz by making a small change to the multiplier in the BIOS.

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

The CPU cooler is fastened with screws, which I think is great as it allows you to really understand how tight the cooler is, much better than with plastic anchor systems. The 4-pin connector for the CPU is located in the middle of the board.

MSI’s Active Phase Switching (APS) is located to the right of the 12V ATX ​​connector. This system is in charge of the automatic regulation in real time of the power fed to the CPU. Actually the power level is illustrated by 4 LEDs which is a nice added feature.

The board has two PCI-E x16 ports and 1 PCI port. As you can see; the PCI-E ports are separated by a fairly large distance. If you use a dual-slot card in the second PCI-E port, you won’t 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; S / PDIF digital and a contact CD.

Integrated chips for sound and Ethernet connectivity are Realtek ALC889 and RTL45CL. Both chips are of high quality and backed by excellent drivers. The Fintek chip located next to the battery takes care of the general I / O functions of the motherboard and also allows 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 in the image below. This change allows us to increase the FSB by up to 35% without having to make any other changes. In principle, this addition is great, but it will only work well if the processor you are using supports overclocking without increasing the voltage.

The rear panel connectivity is excellent; see 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 really important settings are, at least if you want to overclock your system. Although the NF750-G55 can be considered a mid-range motherboard, it offers many possibilities for overclocking both the CPU and the memory modules.

The M-Flash program that is embedded in this BIOS is actually unique to MSI motherboards. It is a smart little program that allows us to update the BIOS and even make backup copies and recover old versions of the BIOS.

There is also a menu called “User Settings”. Allows you to configure different “profiles” of the BIOS settings. This can be useful if you want to quickly load a default overclocking setting for a gaming session or the like.


The CPU performance of the nForce 750a chip is within the range I expected. However, the memory tests came out a bit short, which surprised me as this is usually a strong area with NVIDIA chips.


The HD read and write speeds were very good, which means that NVIDIA has resolved the driver issues that have caused the hard drive to run slower than it should on older chipsets.


What struck me from the above results was the poor WinRAR test results. My conclusion is that it must be due to the memory issue mentioned above.

In testing the IGP GeForce 8200 chip I didn’t get any noticeable results in the 3D test, so it’s easy to conclude that you shouldn’t be using it for gaming. However, it worked well for HD video playback.

The power use of this system is really low, especially when it’s running in idle mode, making it a good option if you’re building a 24/7 system.


NVIDIA has created the classic overclocking chipsets from AMD in the past, including the now near-mythical nForce 2 and nForce 4 platforms. So what about the overclocking capabilities of the nForce 750a SLI? The following screenshots say it all:

I was able to overclock the FSB to 264MHz (!) Which was actually a bit surprising to me, I didn’t expect it to be that “overclockable” being a mid-range card.

I also tried to overclock the integrated graphics card (GeForce 8200). Got it to run stably 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 can be used as a motherboard for an 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 capabilities are excellent, as is its connectivity. The integrated graphics solution is good but not as powerful as some of the integrated chips that AMD / ATI offers.
