Hello!

I just finished my first computer build, aimed at struggling everyday tasks (internet, light photo edition, etc) and of course a bit of gaming. After a lot of research, I chose the MSI B350M Mortar to support my Ryzen 5 configuration. Being budget limited, I was looking for good price-quality ratio and I this MoBo offers a lot of features for the price. What made the difference compared to concurrent offer is the cooling management (number of fan headers, PWM/DC customisable fan control, VRM heatsink) which, combined with very user friendly tools, allow a nice overclocking potential (very important To me for a Ryzen 5 1600 conf).

But move on the product itself. The board is good looking. It is sober with its black/grey colour with slight touches offres red. The red leds are discreet but look nice and perfectly match my GSkill RAM and MSI RX 480 Gaming X GPU. As I already say, that?s my first build but I didn?t have any problem to mount everything. The different headers are well placed and easily accessible, that?s a good point.

Initial boot is really easy with the MSI BIOS. I didn?t meet any compatibility issue, even with the v1.0 BIOS. The B350M Mortar is actually fully Ryzen 5 compatible out of the box. Only the DDR4 is recognize at 2133MHz instead of 2666MHz but a click on the XMP button solved this. Setting fan cooling profiles  and switching from PWM to DC mode is as simple as child?s play (my fan systems have 3 pin connectors). The menus are really intuitive, even for a beginner like me and so as the different utility tools provided with the MoBo and that?s another really good point.

Until today, I only had one issue with the mother board. I had a problem for controlling fans on 2 out of 3 SYS_FAN headers which always ran at full speed and could not be controlled (even in DC mode). Flashing the bios to the latest 1.2 version solved the problem and everything seems to run fine now.

The only missing feature to me is the lack of USB3.0 Gen2. It would have been perfect with it, beeing more futureproof.

My initial thoughts are this is a really good entry level MoBo for gamers on Ryzen set, or even for enthusiast users considering the features it offers f1or the price.

After several days using the motherboard, I'll add another con which is POST time. It takes about 15 seconds between the moment I press the start button and the moment the splash screen appears. It may be not a very long time in absolute but it's half the total boot time of the computer, making it pretty slow to boot to me (I use a SSD). I will flash v1.3 Bios to see if it corrects this. If not, I hope MSI is aware of the "problem" and working on it.

By the way, I can't figure out where to activate Fastboot. I checked the BIOS menus without finding the option. Is Fastboot compatible with B350M Mortar? If yes, how to activate it?

Otherwise, still pleased with this MoBo :D

I've seen the mortar line for motherboards before but actually seeing real pictures of it made me reconsider my purchase of the B350 Tomahawk because I sort of like the small factor builds and motherboards. 

However I got my B350 for $10 more than a B350 where I purchased it so I guess $10 for two PCI connectors and a larger board may have been worth it but overall good build you have!

And the Tomahawk has got more heatsinks for VRM's, which should allow, theortically, a better behaviour while OC. But the Mortar is really good considering its size and price !

I heared this was the integrated GPU LED. As any iGPU was released for Ryzen CPUs yet, everybody should have it on, nothing to worry about.

And for the slow booting time, unfortunately it appears to be quite common with this MoBo, depending on the RAM you use I think. Mine takes time to POST too, about 15-20s.

Did you try monitoring your temperatures  (CPU & GPU) while playing? Your equipment may be too hot, leading to thermal throttling.

Thank you! :)

Concerning the POST time issue reported above, the latest BIOS update 7A37v16 partially corrected the problem. POST time was divided by 2 and is now about7-8s, which is much better (15-20s with previous versions).

I have some info from my own experience with this board that might help you with your long post time issue.

While experimenting with getting my memory going, I noticed a trend. There's a limit beyond which the system won't even boot, of course; but there's a range just below that where the system boots and can enter BIOS, but takes dramatically longer to start(sitting at a black screen for ~15 seconds like you describe,) and something goes wrong where my nvme drive will not be detected. I think it has to do with overloading the SOC? Anyway, I am usually able to leave this state and boot normally by slightly loosening the timings.

My theory is, the XMP profile is putting you in this range. You're not experiencing the boot issues I have because you're not using an nvme boot drive; but are seeing the long post time and might have the odd crash down the line. If I'm right, turning off xmp and manually inputting the same settings but with slightly higher timings could fix the problem and speed up your boot.
