With Advanced Mode, you can create lighting profiles that will switch instantly to your preferred effects. Different light strips sometimes have different RGB pin definitions, RGB Fusion software can intelligently relocate each pin location with RGB Calibration for the best compatibility.

Ultra-Durable GIGABYTE Features

DURABLE AND BUILT TO LAST Sulfur compounds in the air can penetrate tiny on-board resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design, GIGABYTE gives ultra-durable motherboards a whole new meaning.

Make Good Connection and Significantly Lower the Wires Capacity GIGABYTE 400-series motherboards feature solid plated ATX 24pin & ATX 12V 8pin power connectors for offering stable power supply while CPU overloading. With a larger contact area for electricity you get a longer lifespan and is ultra-durable with more metal quanity to sustain higher power and generated heat.

HUMIDITY PROTECTION GLASS FABRIC PCB There is nothing more harmful to the longevity of your PC than moisture, and most parts of the world experience moisture in the air as humidity at some point during the year. GIGABYTE motherboards have been designed to make sure that humidity is never an issue, incorporating a new Glass Fabric PCB technology that repels moisture caused by humid and damp conditions. Glass Fabric PCB technology uses a new PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate compared to traditional motherboard PCBs. This offers much better protection from short circuit and system malfunction caused by humid and damp conditions.


EXTRA STRENGTH WHEN YOU NEED IT MOST Never worry about your heavy graphics card damaging your motherboard again. GIGABYTE’s proprietary Ultra Durable PCIe Metal Shielding reinforces the PCIe connector to prevent slot damage due to heavy graphics card. The DIMM and PCIe metal shield also provides extra strength for when you forget to release the lock while replacing your component, adding a foolproof option which can save your PC’s life.

GIGABYTE BIOS and Applications

REFRESHED BIOS GIGABYTE has specially designed the BIOS to provide users the most premium experience while constructing their new system, with a new GUI and easier to use functionalities. The BIOS is crucial for users during initial setup to allow for the most optimal settings.

GIGABYTE APP Center The GIGABYTE APP Center gives you easy access to a wealth of GIGABYTE apps that help you get the most from your GIGABYTE motherboard. Easily launch all GIGABYTE apps installed on your system, check related updates online, and download the latest apps, drivers, and BIOS.

Gigabyte B450M DS3H, AMD B450, AM4, DDR4, M.2, 2-Way CrossFire, Realtek GbE, USB 3.1 Gen1, MicroATX is rated 3.0 out of 5 by 3.
Rated 2 out of 5 by from RGB Fusion doesn't really work The board works mostly as described, I've had no issues with it apart from the RGB Fusion. All it is capable of doing is displaying a static colour, you can choose the colour but that's it, it can;t do any effects such as colour fade. I think this is due to the RGB Fusion software itself which is terrible. So if you're not bothered about RGB then this board is fine, otherwise avoid it.

Rated 5 out of 5 by from Great This has been bought for my grandson who I have have bought from you before and will do again as he is building his own computer which will take a while as he is only 16 so money is limited but I am very pleased with your service totally

Rated 2 out of 5 by from Good, except the M.2. interface very shonky I've had this board for around 2 months and my PC is still not fully operational. I've been experiencing freezes to the system and the occasional unexplained reboot. It's taken me most of this time to fault find as all components were brand new. It turns out that the M.2 interface is at fault. If I use my m.2 card in a PCIe expansion card the board runs flawlessly. With the m.2 in the on-board slot I get the constant crashing and freezing. Reading around, there are many people with the same issues with Gigabyte boards. If using standard SATA drives, or and M.2 drive on a PCIe card, this board runs well - the M.2. port issue really let the board down. Unfortunately, because of this, I wouldn't recommend this board.

What happened to 'Dual BIOS'?

Do these boards only have one ROM BIOS chip? What happens if your only BIOS chip gets corrupted? I thought that 'Dual BIOS' was a signature feature of all Gigabyte's UltraDurable motherboards. I have always used Gigabyte motherboards, and I will be very disappointed if they have dropped this feature on their mid-range or lower-end motherboards.
