In the dark, starless night, the falcon strikes fear into the heart of its prey. Even with minimal visibility, the falcon pinpoints its prey and patiently anticipates the perfect moment to swoop in for the kill. The falcon with its laser sharp gaze dominates the darkness of night in the same manner that AORUS Core Lighting illuminates the vast AORUS ecosystem.

Great motherboard choice, but buyers beware 9/29/2020 1:13:27 AM

Pros: Has 2 M.2 slots (I think only one is NVMe).
Supports 2400Mhz ram and beyond (up to like 5400Mhz)
Works beautifully with the Rosewill Cube Mini ITX/Micro-ATX/ATX Mid Tower Gaming PC Computer Case.
A huge performance increase from the B350 series of motherboards.

Cons: Does not support Ryzen Gen 2 at all, wording on the page says supports Gen 3 and beyond. Does not indicate it isn't backwards compatible.
Noting this con specifically because I made the error after doing a week of research and even looked at the Gigabyte official support page.

Overall Review: I would highly recommend this motherboard if you have a Gen 3 or soon to be released Gen 4 Ryzen processor.
The board was easy to install, attach components to and just works.
The manual is detailed and explains everything you need for Front Panel case connections.
The Bios screen is very easy to work with and get setup to your needs.

Unable to Post 9/20/2020 9:21:57 PM

Pros: Aesthetics, connections, options .. Very nice indeed...

Cons: Moved my thermaltake 850 and case fans from my working old box to the new SAMA, after coupling my amd ryzen 9 3900x to this board. After everything was connected, I turned on the PSU and hit the power button: the 2 case fans that I had added, and the Prism cpu cooler revved up with lights. Add the CPU diagnostics light as a bonus, but no boot post tones of any kind. I tried every option, including breadboxing, same results: the only things that would load up are the fans that require 5v. Nothing requiring 12v input worked. I tested all my PSU lines, no issues. I moved my PSU back to the old box and connected to the mobo: booted up and posted like a charm. Upon disassembly of the new board and CPU/prism combo, I discovered that the CPU had never even warmed up to melt the paste and spread it evenly across the CPU surface. Also, side note, the Q flash plus never responded to my attempts to update the bios - no lights of any kind!
I moved everything back to my old system and it booted flawlessly.

To make things worse, due to extended waiting for the various components, I am well past my ONE MONTH NEW EGG deadline for returns ...

Overall Review: At this point, I personally cannot recommend this product. However, a lot of reviews say I just got the lemon in the bunch.

Depending on what kind of response I get from New Egg and/or Gigabyte, my disposition might or might not change ..

Great mother board 8/25/2020 12:58:13 PM

Pros: Dropped this in a fresh gaming pc build over the weekend and had the pc up and running in about 2 hours. Mobo is super straight forward, has all the headers you’d ever need and everything is placed well on the board.

Cons: Only thing I had trouble with (probably on my end, not Gigabyte’s) was getting sound on my tv (using a tv instead of monitor). When I booted everything up, it said it was running sound through the Realtek digital optic audio and i downloaded the drivers and installed them and restarted the tower. No sound still; plugged in A headset and got sound through those. So I started trying to see what was going on and didn’t find anything. Only way I got the sound to come on the tv was by updating the gpu drivers and got sound through regular hdmi. Would’ve liked to use the digital optic audio from the board but at least I have sound.

Overall Review: I’d say definitely get this product. Super easy to setup and has headers for everything you will need to plug in

Why even bother getting it for the built-in wifi? 8/22/2020 12:38:43 AM

Overall Review: I got this board so that i would have more expansion slots for stuff like SSD, RAM, GPU etc. And it had the built-in wifi, so i thought it would be a good pick. Well the wifi doesn't actually seem to work, claiming that my PC is using an incorrect or nonexistent DNS server while my old board didn't have that issue. Why have on board wifi if its not even gonna work properly?

Very Satisfied with This Board 8/18/2020 7:13:39 AM

Pros: - Good layout
- Plenty of USB ports of various versions
- Sturdy
- Worked the first time with the components I have
- BIOS provides everything I need, and then some
- Windows 10 Pro like it

Cons: - None thus far.
- If anything, the available software utilities are the typical bloatware, but solved by simply not installing them.

Overall Review: I’ve been using Gigabyte MBs for years, since Asus had a capacitor QC problem over a decade ago. I have never had a reliability problem with Gigabyte.

I am not used to assembling much of anything that works the first time. So, I am impressed that this build has worked right out of the chute with no backtalk. What I have thus far is:
• Gigabyte B550 Aorus Pro AC motherboard
• AMD RYZEN 5 3600 Processor
• G. Skill Flare X Series 32GB (2 x 16GB) DDR4 Memory Model F4-3200C16D-32GFX
• SAMSUNG 970 EVO Plus M.2 2280 1TB SSD
• Noctua NH-U12S Chroma (bought elsewhere, they only had the Chroma model in stock)
• EVGA GTX 1660 SC Ultra
• Existing Corsair HX650 Power Supply
• Fractal Design Define C case using 2 Silent Wings 3 140mm and 1 120mm PWM fans

Everything went together, POSTed properly and booted the first time. It came with the F1 BIOS which I updated to F2 and later F3 without any issue. It passed numerous Memtest cycles, including a 24-hour test, and a considerable amount of time running Passmark. Windows 10 Pro installed without any complaints (other than the Resume on Alarm note below) and has not given me any problems thus far. This build worked harder on the test bench than it will in service.

As for the motherboard, itself, the layout is good, it feels substantial, and the overall quality does Gigabyte proud. The layout looks to be a good design. It has plenty of fan headers. Overall, there is nothing I want that it does not have. The BIOS is easy to work with. The heatsinks included for M2 SSDs are appreciated, and fairly beefy for stock units. There are a ton of various USB ports on the back plane and headers on the MB. I don’t care about LEDs, other than the diagnostic ones on the motherboard (which work).

The memory installed and was recognized fine, although initially at 2133 vs. 3200. I enabled XPM in the BIOS, and it responded with a memory profile with the correct timings and adjusted voltage, then everything was fine. That configuration is what Memtest and Passmark have run on without failure.

I installed the device drivers from Gigabyte's web site, but not the utility software. I have used Gigabyte software before, and while some may like or want it, there is nothing there I need for my application and I don't want to install it for the sake of installing it. I set the fan profiles in the BIOS and don't want their software monkeying around with it.

If anyone is going to use the Resume on Alarm function to automatically power the system up at a specified time, it did not work for me initially regardless of the BIOS settings. That turned out to be a Windows registry entry. If anybody is interested, make sure HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power, HiberbootEnabled DWORD is set to zero. My installation had it set to 1 by default. This is not a motherboard issue, but a Windows feature that speeds startup but wreaks havoc with Resume on Alarm or Wake on LAN. Amazing what one can find on the internet!

Based on what I have seen thus far, I have no reason to expect any hardware or compatibility problems going forward. While this build will not be worked hard, it needs to work reliably.

Flaky connections 8/9/2020 12:12:23 PM

Pros: Nice features
Easy to work around

Cons: It will not hold a Bluetooth connection to my headphones that work with everything else. I'm going to try a USB BT fob.
I also appear to have flaky USB 2.0 ports right off the back of the motherboard.

Overall Review: Would not recommend, would not buy again.

Works great 8/8/2020 3:02:54 PM

Pros: Easy install and set up. Easy install CPU and video card. Plenty of case fan headers. Fast AC on board wifi so I ditched my usb wifi adapter. You can use the antenna or not. Seems just as fast either way.

Cons: second m.2 connector is slightly underneath video card so have to remove card to access. So I used the PCI Express x16 slot (PCIEX4) slot to add m.2 adapter card.

Overall Review: The board fits my needs for editing photo and video. I'm not a gamer. It has everything I need.
