HASH(0x9ea01a74) out of 5 stars Two, yes 2, RMA's into it. Nov. 21 2012
By Marc M. - Published on

So after a month of using this Mobo, it's giving me nothing but troubles. I installed it with an Intel i5-3570k (stock only, no OC), 16GB of Corsair Dominator GT 2133mhz, and a Diamond brand AMD HD5870. After several bios updates and "Live Update" updates, it keeps crashing.

Not so much "crashing" as completely freezing. I mean everything. USB turns off, mouse and keyboard don't respond. Screen freezes (still showing whatever was there). Audio cuts off.

I'm going to have to RMA this board, because it is now 41 days since I bought it. This is a HUGE disappointment.

UPDATE: I decided to not RMA the board originally, since some of the issues pointed to a possibly bad Graphics Card. So I installed a new MSI GTX 660ti OC, a new 240GB Kingston Hyper X SSD and unfortunately Windows 8 Pro. (By the way, never upgrade to Windows 8, just my opinion).

The problems stated previously became much much worse over the couple of weeks. So I finally broke down and RMA'd the board. I will update again when I get it back.


So here's the Update:

As I stated, it uses the new MSI GTX 660ti with the Kingston SSD.

This second board is bad as well. The USB controller randomly freezes and forces a hard reset. It also won't allow the USB to come online in time to make it to the bios (by pushing Del on the keyboard). I'm not going to RMA this one. I'm going to buy a new mobo, from a different manufacturer when I can afford it. I'm done with MSI for mobos.

On a side note: The MSI GTX 660ti (oc) is doing quite well.

3rd and final update: (9/26/13)
I've had to RMA the second board for freezing, lockups and hanging. I'm done with it. I bought an ASRock Extreme 4 board to replace it with and will just sell off the returned (3rd) MSI board when it gets to me.

I will never purchase another MSI mainboard.

I have had MSI boards before and had good luck with them. I expected no different and have not been disappointed. I basically gutted my system and replaced it with the new stuff;

Intel i5-3570K
16GB of Kingston RAM (2 x 8GB)
SAMSUNG 840 Pro 256GB boot drive
Cool Master Hyper 212 Evo CPU Cooler

This is a darn peppy configuration, coming from my Core 2 Duo E8400 processor. My Windows Experience numbers are CPU 7.6, Memory, 7.6, Video (both flavors) 7.8 (this is my old MSI 560Ti Twin Frozr video card), and Primary Hard Drive 7.9. This system goes from button press to login in about 20 seconds. Microsoft Word SNAPS open and some of my slower applications are now much more reponsive. I have run 4 Windows 2008 R2 server VMs (via VirtualBox) at the same time and the system is still responsive, as if it is idling otherwise. I clicked the O/C Genie button and it automatically overclocked my processor to 4.2GHz (from 3.4GHz) and ran stable, upping my Windows Experience points to 7.7 for the processor. I returned it to stock just because I am running a generic powersupply which did not have the necessary EPS power plug for the motherboard. In any case, I am VERY happy with this purchase and highly recommend this motherboard.

HASH(0xa06caf30) out of 5 stars Easy as pie overclock Feb. 8 2013

I moved my i5-2500K from my prior MSI P67A to this new Z77. Installed a new GTX 670 4GB, 128 GB Crucial M4 SSD, and 8GB (2x4) GSkill Ripjaws (8-8-8-24)........using OC Genie, the bios shows 4200 MHz and 8-8-8-24 ram button press is all it took to get 900 free MHz of OC!

Ran OCCT, IntelBurn test, and prime95, and a few hours of BF3..........not a single hiccup!

There's not anything I dislike about this MSI board. If it lasts, I'll be very happy, but so far so very good.

HASH(0x9f5220a8) out of 5 stars Great motherboard but, read the rest of my review. July 24 2012

Okay right off the start I loved how sturdy the motherboard felt everything seems to be made of quality parts.
The BIOS looked insanely easy to manage.
Another thing I loved was that I didn't have to reformat my SSD for this new motherboard and processor since I'm coming from a core 2 quad Q8400 however, on my old motherboard I did have to reformat to use it otherwise it won't load the desktop.

Ok here's the small trouble I ran into with this motherboard.
I had a problem with getting internet to work but all I had to do was go on the website and looked up the model and searched for the drivers for the Ethernet and it worked fine after that.
The drivers might have been on the drivers and utilities CD all along but I never had a chance to check it.

My conclusion would be, great board thank god i had small hiccups of troubles and didn't get anything defective to have to go through RMA headaches.

p.s I can't get my corsair vengeance 1600MHz ram to run so stable 1600MHz it's at 1333 not that I really mind but if someone could help me with this would be great

I installed this along with an i7-3770K about a week ago, and so far it's been running very solid. I haven't overclocked it yet (still not sure if I need to), but I feel that this board was a great value. I haven't run a true stress test on it yet, but I have processed some 1GB images in photoshop that took the CPU up to around 80% with no problems.

I'm not too much into gaming anymore, now I use my computer more for photo and video editing. My setup right now is this board, the CPU I mentioned above, a Corsair H80 watercooler and 32GB of Gskill RAM. Compared to my old system (i5 overclocked to 3.7 GHz with 8GB RAM), this is a huge improvement!

The number of USB 3.0 ports is limited compared to the higher-priced models, but I purchased a pci-e expansion card and doubled my 3.0 ports and still saved a few bucks as compared to the next-higher model.

I did quite a bit of research before choosing this mobo and I didn't see anything to dissuade me from getting this model. As many reviewers stated, this motherboard is truly a great value.
