The B150M takes one more step upscale from the recently reviewed H110M Grenade. Is Intel’s higher market B150 chipset worth the extra money?
Last summer’s H110M Pro D review successfully tested my theory that even the cheapest motherboard can provide full graphics performance when all of the CPU's 16 PCIe 3.0 lanes are connected to the primary graphics card slot. My subsequent H110M Grenade review showed that for a few dollars more you could get an M.2 slot and some additional ports. Intel’s H170 offers RAID and even more ports at the top of the mainstream motherboard segment, and the B150 sits between it and the H110.
Today's question, then: Is MSI’s B150M Mortar Arctic worth its premium over the company's own well-equipped H110M Pro D?
The most notable improvements appear to be that we’re gaining some USB 3.1 Gen 1 (aka USB 3.0) ports, another pair of DIMM slots, and a PCIe x4 slot. We’ll have to go to the tests to look for more differences.
One More Step Up in the Mainstream
A unique look fits the Arctic name, and looking at it actually made me feel a chill. Even the CPU socket cover is snow white. The board is nice and thick, with no notable flex, even if picked up by a corner. The primary PCIe slot also has a metal frame to reduce any flex from a heavy graphics card. There is plenty of finger room where needed, and clearly silk-screened pin-outs near the front panel and speaker headers make referring to the manual unnecessary.
Looking at it from the front edge and starting at the left rear, the audio circuitry is surrounded by an LED-illuminated border, which can be given a breathing effect (I just think it’s a good pilot light). Moving forward along the edge are the front audio header and the SYSFAN1 header. Next is a JLED1 header, which is intended to provide power to a single color LED strip controlled by MSI’s Gaming App software. COM1 and TPM headers are next, then a two-pin JME1 header that is not described.
The single USB 2.0 header comes next, with a shroud around it. Intrusion detection and the CMOS-clearing pins (labelled JBAT1) are next, then the front panel headers. These have clearly silk-screened labels near them, making references to manual images unnecessary. There is no manual entry for a JSPI1 header near the front corner.
Along the front edge, the SATA 6Gb/s and USB 3.0 headers are angled to face the front of the board. The SATA ports do not alternate, so you’ll need to remove the top one to access the latch on the one beneath. The ATX power connector is next, followed by four diagnostic LEDs for each of four subsystems, boot device, VGA, DRAM, and CPU. If the board won’t boot, one of these may tell you why not. Another undescribed two-pin header labelled “J1” is next, and the SYSFAN2 header finishes the front edge.
The SYSFAN3 header is the first feature moving back along the right edge, and the CPUFAN header is behind the right DIMM latches. Both sides of the DIMM slots have latches. The CPU Power connector is the only other feature on the right edge, and has plenty of finger room between it and the I/O panel connectors. Behind those and to the left of one VRM heatsink is the M2_2 connector, meant for a WLAN card. The rear panel I/O plate has punch-outs for a pair of antennas. The first PCIe slot has a metal frame around it. The M2_1 slot is to its left, and will be covered by a double-slot graphics card. There is only one PCIe x1 slot on this board, and there's a full length PCIe slot that is only wired to four lanes.
In addition to the board you get a pair of SATA cables, driver CD, a quick installation guide, and an 8-1/4” x 5-1/2” manual. It has 36 pages in each of only four languages: English, German, French, and Russian. It is glue bound and won’t lie flat, but the type was easy on my older eyes, and there are also some good diagrams.
Some of those pages were given over to more descriptions of the BIOS than I’ve been used to seeing recently. Here are some of the screens from that BIOS:
If you’ve used a MSI board recently, you’ve seen this intro BIOS screen.
It is worth pointing out that the M.2 drive I installed never appeared here, even after it had been partitioned, formatted, and tested.
The only thing I typically change here is to turn off the abominable NumLock. If that dates me to the original IBM PC keyboard, so be it. (As an overclocker, I love NumLock -ed.)
This is the default fan curve, which starts out very low at low temperatures. I tweaked this a little, as a mere 13% seemed too low. There will be a comment about this later in the results; it made a difference.
Here, you can click over any highlighted area and see what is installed there. It’s not perfect. As you can see I have highlighted the M.2_1 connector, and it does not show the installed drive. Everything else was there.
