So far, so good! I liked that all of the drivers were preinstalled and upon first bootup a client ran that updated everything.

functional but not ideal if you want any RGB. only one header.

No issues, though it doesn't have a USB-C header, and is confined to PCI gen 3 speeds.

Fit all of my parts without a problem. Built-in wifi works great for me. Came with support for 5000 series chips, no bios upgrade needed. Got it on sale for cheap, probably still worth it even at $70

Good motherboard with good antennas, not those abomination of wired antennas. Only complaint is no ARGB headers on the motherboard, but it's a B450.

Really basic board. Took off 1 star for really weird PCIe slot positioning - in a mATX case the GPU will occupy the middle 2 slots rather than the upper 2 like most mATX boards. This results in much worse headroom for the GPU to breathe, and, therefore worse temps. Saw temps climb from 66-67C with an ASRock A320M-HDV to 72C with this board. Took off another star for mediocre WiFi at best (though you would expect this from a cheaper board like this) and the I/O ports positions. Really dumb; you can't use a GPU that's more than 2.5 slots thick because USB and Audio headers are on the bottom. Most other mATX boards I've used have them on the side. These 2 things combined make it very hard for the GPU to live its life.

BIOS out of the box worked with the CPU. Basic as all can be board with only two fan headers which sucks. But, for the price are we really complaining? For a budget build, I'm good with it.

Good motherboard for the price, many mention it having a small amount of fan headers, but had plenty for my build, I did purchase a 2-pack of splitters for around $10 in case I need them down the road. Would recommend for a budget-build or a smaller-body PC.

This board has very little going for it on paper, especially in 2023, but it's done well-ish for me as a compatibility purchase for an existing Raven Ridge APU. Let's break this down:

The good

I/O is very solid for B450 with eight rear USB-A (4x 2.0 + 4x 3.0).

VRM is impressive considering the class of board this is; it runs significantly cooler than the beefier-looking MSI B450M Bazooka, which means putting a solid OC on a 6-core chip is absolutely possible.

Support for every AM4 Ryzen CPU simultaneously, with later BIOSes only pulling support for A series APUs. Current revision has Zen 3 support out of the box.

I/O shield is designed correctly and doesn't try to eat the HDMI port like everyone else's does.

Ram slots hinged at both ends! I have no idea why this is so difficult for board manufacturers now but it makes installing memory fifty times easier.

The Bad

Two NICs and both of them are Realtek on the latest PCB revision. Currently attempting to unbork the WiFi drivers as I type this; considering just swapping the chipset for an Intel one I harvested from another board.

No BIOS flashback. A non-issue considering the age of the board and the fact that it's not needed on the Rev 1.3 PCB, but MSI does have an edge here.

No PCIe Gen 4 hack on later BIOSes, which I recognize is a silly complaint, but again, MSI can do this and Gigabyte can't, at least on the budget boards (it's documented as working on the B450 Aorus M).

No search function in BIOS, but that's nitpicky considering again, MSI were the only ones doing that in 2018. Honestly, the BIOS is just generally laid out in a manner that makes no sense, and bizarrely there is no one unified overclocking tab so CPU and memory settings are scattered all over the menus.

PCB is brown, not black, so consider that in the aesthetics of the build. It's also a hair narrower than standard mATX, which meant that in my particular chassis, the right middle standoff missed its hole by about two inches and made the board tricky to mount.

The Ugly

Only one chassis fan header and no CPU OPT or AIO pump header. Are you ******** me, Gigabyte? This board has more RGB headers than it has fan headers! It's a good thing I had two fan splitters on hand, otherwise I'd have had to majorly rethink the case setup.

The board wasted no time in attempting to kill my chip with runaway SOC voltage upon enabling XMP, to the tune of "1.2v" set with spikes above 1.3 at partial load. It also does not support negative vSOC offsets, which means that after manual tweaking the lowest it'll go is a safe but unnecessary 1.1v. This behaviour is present on all of the three most recent BIOS versions. As well, some voltage values shown in BIOS (worryingly, including vcore) do not match their hwinfo readings at all, so watch your voltages on this board.

RGB Fusion is, despite years of updates, as messy as ever. None of the effects aside from breathing will save to firmware, which means that while I can set any effect including a solid colour from within RGB fusion, restarting the PC will lead to that colour showing in a breathing effect until RGB fusion is opened. The alternative is to leave RGB off entirely. Interestingly, the default solid red does not have this problem, but I have no idea how to restore that state.

Overall, this board is very much something you should only buy if you need compatibility with an older Ryzen CPU and there is no other option. It does well to avoid the main technical grievances that enthusiast harp on with cheap boards, but it manages to be so painfully under-engineered everywhere else as to be more of a hindrance than a help. Infuriatingly, most of the bugs are software-related; my concerns with the hardware are minor but unsafe/misleading BIOS set voltages and broken RGB software are not acceptable issues when the manufacturer has had five years since launch to get the board ironed out. If B550 or A520 isn't an option, just get something used from MSI or Asus with a 64 MB BIOS chip and save yourself the hassle of fighting this thing. Put simply, the B450M DS3H has been functional as a cost-effective option but mildly frustrating to work with at almost every turn, a disappointment considering how good Gigabyte's successor B550 lineup is.

It's budget. It's a perfectly serviceable motherboard. It has the bare essentials that most people need, and it does pretty good at just that. Knocked off a star because of only one case fan header, and the position of it being kinda weird.
