B3 Stepping Ready

To fix Intel’s 6 Series chipset design error, the SATA problems in its 6 Series chipset, MSI implements the latest Intel B3 Stepping 6 Series chipset on its P67/H67 mainboards for fixing SATA problems in the Intel Series 6 chipsets. Consumers can now identify the latest MSI P67/H67 mainboards equipped with the Intel B3 Stepping chipset with the MSI B3 Stepping Ready logo. This provides a more confident way to identify your next-generation P67/H67 mainboard.


Military Class II

The perfect trinity of quality, stability and efficiency all exist at one mainboard to meet end user expectations. The MSI Military Class II series products provide the long lifespan, unparalleled quality, extreme performance and ultimate efficiency.

Hi-c CAP
8X Lifespan than solid Capacitor!!
Insisting on the best stability, MSI utilizes Hi-c CAPs on Military Class series.  Made of the rare element Tantalum, often used on space shuttles and satellites, which sustains very high temperatures and shows an amazingly high electrical conductivity.

SFC(Super Ferrite Choke).The super Ferrite Chokes use a Ferrite core that is Super-Permeable. Compare with traditional choke, the Super Ferrite Chokes run at a 35 degree Celsius lower temperature. The lower working temperature will enhance mainboard stability.

Solid CAP
10 years long lifespan
For providing the highest quality products, we built-in Solid CAP in the entire Military Class series. This not only makes bursting capacitors a non-issue but also ensures a dramatically extended lifetime and ultra-low ESR.

APS (Active Phase Switching)

Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage. 



Compared to common mainboard which need extra BIOS chips, MSI’s M-Flash has a double advantage which doesn’t need extra components and secondly, all your BIOS data will be saved in the USB drive. The stored data does not only have backup and upgrade function, moreover it can also be seen as a portable BIOS chip which is actually able to boot up your PC.

- Backup/Restore Your BIOS to/from Any USB Flash Disk
- Avoid Unnecessary Repair Due to Accident Failures During The Upgrading Process
- Earn more BIOS Lifespan by Reducing Unnecessary Rewriting Process

NXIC RMA service
lemon motherboard
bad QC
April 26tth. Trying to setup my new system, after put everything together, computer starts infinite looping every two seconds. I even could not see BIOS screen. Talk to MSI tech support then RMA to NCIX.

May 16th, A week after I setup system with the motherboard from RMA, it start infinite looping again. RMA

June 25th, Got my 3rd MSI motherboard, installed and power it up, nothing shows, no beeping, no looping, LED lights up, fans sipn, but just show nothing with different video card.

Will be my first and last MSI MB, I will buy asus or ASRock next time. One star for NXIC RMA.

CPU: i5 2500K
VideoCard: Gigabyte GTX460 1G
PS: SliverStone ST 1000W
Memory: G.SKILL Ripjaws DDR3 1333

Experience: 5 Days
Looks Sexy, Lots of USB 2.0 and 3.0, SLI Ready, Lots of space for PCI, OC Switch.
Bought the Motherboard and I'm really impressed for the price. You could pay about 200$ for an ASUS for example and get the same thing. I only payed 135$ after the rebate. All in all this is a great buy and I would recommend it.

Experience: 4 Weeks

Easy OC button.
Many USB 3.0.
Click bios.
Sata3 6gb/s
I've bought this for my i7 2600k and i'm really happy of the results. I also have 1666mghz ram. Really easy to use the overclock tool and i got no problem with my ram. Also the Sata3 is really a nice feature.

Experience: 2 Weeks

Solid quality
Price (considering rebate)
Only 1 usb header
Got this with i7 2600k. Love the click bios interface and the utilities are actually useful. CPUID HWMonitor tells me the temperatures are 36, 40 and 33c while idle which seems pretty good to me. Got all the expansion slots I need, cheap compared to ASUS boards with seam features.

Only complaint is it only has 1 usb header (one that allows 15 ohms instead of 5) which means my card reader doesn't work when I turn supercharge on, and I also can not use my front case USB ports!

Experience: 7 Days
new bios interface, tons of usb ports, comes with extra usb3 bracket, sli/crossfire ready, cheaper than asus mobos with same features
non that i can think of
Got this with an i5 2500k. POSTed on first boot. Recognized all my hardware. So easy to work with. I was going to buy an Asus mobo but their sli/crossfire ready boards were around 200, their most affordable sli ready board was a mATX.Comparing this to Asus, i found that this has more features for the price. I am happy with this motherboard so far.

Experience: 12 Days

Fairly good price. Great overclocker.
No eSATA. could be cheaper
I really like this board. Over clocked my i5 specialK to 5ghz
first try, with very little effort on my part. It could use a couple of more SATA ports and an eSATA external port. But other than that I cannot complain. The new BIOS is sweet and my mouse works fine with it. Had no problem recognizing both OCZ and Mushkin RAM. Seems very stable and temperatures are fairly low even when running at 5ghz. This is the best board I have owned so far, and do not regret switching from my usual Gigabyte purchases. I recommend it.
