Purchased January 2008. Still in use today 2/2/2017 9:51:01 PM

Pros: Fast. 4x crossfire. Dual bios. 8 gigs of ddr2 support. All the sockets and connections you need for an AM2+ build

Cons: I can't think of any

Overall Review: I used it from jan 08 to jan 2010 then upgraded to a new build. I gave this build to another person and he has used this motherboard 2-6 hours a day every week since.

When I used it I had 3 gpu xfire 3870s setup . He has been using 3 xfx 6970's since they first launched in late 2011(?). I had 8 gigs of 1066 ddr since day one from G.Skill. Initially running a phenom x4 9600. I later upgraded to a phenom II x6 for him which would be the only real change besides hdd to SSD and gpu from what I had to his 6970's. Incredible to be honest. The board probably has 50k hours of usage at this point. He said it runs plenty of games fine from recent years, but shows age.

MSI did a great job. so did XFX on their AMD gpu's and gskill on their ram and rosewill for their PSU.

Lasted 8 years! 3/14/2016 9:52:05 AM

Pros: It was almost the perfect motherboard for my rig for 8 years. Amazing reliability. At one point it had over 8900 hours of uptime without a reboot. It was just an amazing board.

Cons: CPU fan mounting bracket becomes brittle over time. Took 6 years of regular maintenance before it finally gave out. Had to order a replacement.

Processor socket lever to lock in the CPU broke at around year 6, a couple months before the fan bracket broke. I suspect these two issues were inevitable due to the massive heat output with a Phenom 9950 Black Edition. Easy workaround is to make sure you have a nice tight fit up with your fan bracket to keep the CPU mashed into the socket.

Overall Review: Finally broke down 2 days ago. Had a major system halt. Attempted to reboot, would not even make it to post. The lights are on, but no one is home. Thankfully, everything else can still be salvaged. Hell, the CPU is still good. I only recently put in new RAM to upgrade from 4 to 8 GB. I still have the original Patriot sticks I purchased during the build. The only thing on my rig that is not original is the PSU. It was not quality rated and after 8900 hours, it finally gave out and caught on fire. Replaced it with a 600W 80 Bronze one from Best Buy and it kept chugging along for several more years without issue.

I absolutely loved this motherboard. I am so grateful for MSI's craftsmanship. You can look forward to me purchasing the MSI 970 Gaming motherboard soon. I can't wait to see how it fairs.

Thank you again MSI.

5+ Years 11/24/2013 1:34:59 PM

Pros: I have had this Motherboard in my desktop for over 5 years. Was able to upgrade the pro0cessor to a Phenom II after two years, that was great. It is still working extremely well. No issues.

Cons: None.

Overall Review: Wondering if I can upgrade to DDR3 memory?

Still Chugging along 3/17/2013 5:43:59 PM

Pros: I have also had this for 5 years now, never had serious issues.
Supports AM3 processors like the Phenom II series, I upgraded a couple years ago to the x6 1090T and am loving it! still one of the top CPUs for gaming with AMD and well supported on this old motherboard.
Overclocking is very easy.

Cons: I have had the occasional lockup, but not sure if it is related to the motherboard or if it is an overclocking stability issue...

Overall Review: DDR2 RAM is still expensive, lol... but the RAM I originally put in here is still working great and benchmarks very well

Best mobo I've ever owned 2/5/2013 11:21:22 PM

Pros: 5 years old and still going strong. Never once had a single issue with it.

Supported such a wide range of parts that I've been able to upgrade roughly every year since I purchased it.

Currently going to purchase a higher end PCI-E 2.0 video card to push this to its limits and hopefully get another couple of years out of it.

Cons: Not AM3. But this came out before AM3 really took off.

Overall Review: Reviewers that rated this board poorly either had fluke boards or never owned it in the first place. It is a flawless mobo. A+

Still in my case 3/23/2012 12:16:06 AM

Pros: Very stable and reliable MB that gave me almost everything. Easy maintenance.

Cons: Mising wake on LAN feature and missing TPM modul. In the MSI internet site there was a misleading description for a long time that it is "(optional)" feature now I see that this statement is deleted and just the user's manual contains instructions "how to" plug in a TPM Modul (optional) to TPM pin header, but the MB pins are missing, just "dots" are showing where the Modul should be pluged in.

Overall Review: I do have one TPM Modul but I've no idea how to use it without pin header. So my idea was to solder pin header on the bottom side of the motherboard where the 'optional' JTPM wholes are indicated. I wrote to MSI but the support gave me a laconic answer that is not possible.

Excellent Motherboard 6/6/2009 7:21:07 AM

Pros: Couple this motherboard with an Athlon X2 3GHZ CPU and 4GB of DDR2 800 memory and you have a very nice machine for editing video! I'm very satisified with the speed at which it can render video, one of my main concerns when I put this machine together.

Cons: None - everything fine worked 1st time
