Easy to setup mobo. 9/15/2016 5:15:09 PM

Pros: -Love the ease of install of computer hardware.
-Fast and reliable.
-LOTS of potential for upgrade. It's why I bought this mobo.

Cons: -Still haven't found any.

Overall Review: If you're looking for a good build, definitely give this a go. The MSI "optimizing" function could use some optimizing itself though.

Good Board MSI 4/11/2015 1:27:00 PM

Pros: Board has been rock solid no issues so far with this board. I was an Asus fan for years until my last few purchases with them and the quality has gone down hill, Board is easy to setup and the quick boot options allow my PC to load fully into 8 with Raid 0 SSDs in like 6 secs from cold boot :)

Cons: Haven't found one yet...

Overall Review: Looks like MSI has a new fan boy!

Great while it lasted 4/7/2015 3:34:01 PM

Pros: Great features, tons of room for components and upgrades, supports great memory standards and the best current processors from intel.

Cons: The layout is in all honesty.... poor. The usb 3.0 for the front panel is in a horrible location on the front edge of the board and it creates a ton of cable clutter being right there with the sata's and the power 24 pin.

Biggest con through is after a month my pc strangely started just randomly crashing. Not BSOD, straight up crashing as if it lost power. Resetting power cables, checking connections seemed to resolve it. Two weeks later it happened again but a simple boot into safe mode and some diagnostic tests fixes it. A month later and I think I have a power issue as it is becoming common. I replace my APC, no change. Maybe it is something in a windows update or anti virus? System restore no go. Perhaps it is bad memory, memtest says no. Finally I outright buy a new power supply thinking this has to be it. I even change out all the cables and re run them with the new cords on the off chance it was a bad psu power cord. No joy.

Here a little over 3 months after purchase this mobo will not only not post, it won't even power on in the first place past some activity lights on the ethernet port. MSI's response? Enjoy a 1-3 week RMA process where we may just send this same board back and might even charge you for a new one.

Overall Review: I have used MSI boards almost exclusively since I started building pc's something like 15 years ago. This is the first one I have had be a complete bust. I haven't lost faith in them but I will say you may want to shy away from this one for awhile until it seems more revisions.

Love this Mobo 3/30/2015 1:27:11 PM

Pros: Great for overclocking. I could go into all the little details as to why I love this board, but if you like to tweak and overclock this board is superb. Whoever designed this board obviously has years experience doing so, because it's the little things that matter. A clear CMOS button on the I/O panel, for instance, is so nice for when your OC fails. Sure beats opening the case and moving a jumper or taking the battery out. I could go on and on, but this board is just awesome.

Cons: I can't think of any cons.

Overall Review: This is the first MSI board I've ever owned, and I absolutely love it. I was on the fence between this and one of the X99 Asus boards. I'm so glad I came to my decision, I haven't been this happy with a motherboard in a long time

MSI For the Win 2/10/2015 9:42:04 AM

Pros: Amazing Bios interface. Easy one click overclocking for dummies, advanced settings for hardcore OCing, and all around great features.

Cons: Only Con I have is if I use the "MSI Fast Boot" with Windows 8.1 I get a blue screen on startup. The regular "Fast Boot" setting works, but the fastest does not.

Overall Review: I had an older MSI Eclipse SLI motherboard running the older Intel Extreme setup. I have never had any issues with MSI like I have had with similar brands.

Overall good experience, some cons 1/25/2015 2:21:17 PM

Pros: Worked out of the box, at least after I solved a problem with one of my DDR4 modules. Nice OC tools, good looking, M2 x4. Good for last 8 weeks.

Cons: With 5820k and this MOBO's PCI layout I cannot run my 2 Asus GTX 970 in x16 x8 mode (would be a case for most non reference GPUs). As I need to place my GPUs in slot 1 and 3 (to leave some venting space), I can only run them x8 x8. No big deal according to various benchmarks, still disappointing set-up (x16 x8 only with PCI slot 1 and 2). I would assume that most of the users will use non-reference cards, x16 x8 should be set for PCI 1 and 3.

Overall Review: At this point my CPU is OC to 4.4GHz, stable according to XTU stress test (Prime95 crashes, but folks question compatibility of Prime95 with Haswell). Might be able to move higher (work in progress). Using G.Skill DDR4 2400 OC'ed to 2666.

Disappointed and confused 1/17/2015 9:48:26 AM

Pros: I have bought MSI products in the past and was very happy with their products.

Cons: Once I built my rig I discovered something odd. If I put my ram( Ripjaws DDR 4 2400 4x8GB) in the Dimm1 slot it would boot but as soon as I added any of the others to the Dimm5 or others slots, I'd get errors. I tested the other ram sticks in slot 1 and they work fine. Called MSI tech support and they asked if the bios was ver 22.3. What was listed was a long string of numbers and letters. They have not responded since.
