I just wanted to share my experience of Gigabyte X570 AORUS Master with you. Maybe some of you will have the same issues I experienced. I tried to go back in posts but there's no way I can read almost 800 pages of posts
This will be a little long probably. Apologies for the wall of text.
I'll give my specs first so you know what I have, it's nothing special.
Gigabyte X570 Aorus Master (rev. 1.x) F11
3950x CPU (no overclock, cooled with a Corsair H150i PRO)
32GBx2 RAM set to XMP(CMK64GX4M2D3600C18)
Zotac GTX1080 GPU
Corsair Obsidian 750D Airflow (with 2x Noctua NF-A14 iPPC 3000 fans mounted on front)
HW installation: I received motherboard, ram and cpu just a few days before Christmas 2019. Installation went kind of OK, however I had some trouble mounting the motherboard, I/O side and I/O shiled insisted not fitting in correctly. This is the 3rd motherboard I'm installing the same case and only one causing issues, but I'm happy to take the blame on my fat fingers.
BIOS Issues: After I see the post screen, I went into BIOS settings, loaded optimized defaults and enabled XMP. Installed Win10/Linux fine performance is great. However almost everytime I restarted my computer it was causing BIOS to reset all settings and go back to defaults. When I go to BIOS settings it displays a message saying "BIOS has been reset. Please re-config your BIOS setup items if needed". Because I switch between Win10 and Linux quite often I had to fix my BIOS several times a day. Eventually it got a little worse. It started to switch between primary and backup BIOS after self-resets. It also was switching to primary if I set BIOS_SW to 2 and when I switched to 1 it was switching to backup. Absolute mess. I had to remove battery and do a primary/backup flash to F11 again. At the moment it's stable-ish. I'm still getting a BIOS reset at least once a week.
BSOD issues: Just like everyone else, I do series of benchmarks and torture tests when I put a new computer together. First I did an overnight memtest, that was all good. Next, I left OCCT standard test overnight and that was stable too. However when I tried anything with AVX or AVX2 I was getting and instant BSOD. I switched to Linux and ran Prime95 with Small FFTs settings and as soon as I start the test one of the cores was stoping with hardware error message. After few tries I realised it was always the same core, C13. Please remember, I don't have any overclock enabled. No auto-overclock or PBO. I tested it few different ways and everytime I managed to get same failure on Core13. Since it was one and same core all the time I thought it would be a faulty CPU. I contacted AMD and they kindly gave me a replacement CPU very quickly. However with the new CPU things weren't perfect. Again, Core 13 fails. This time usually only one thread (worker) fails, sometimes both but I don't get any BSOD. Yay... I guess. Before you say, yes it works fine when I enable PBO because it seems like a VCore issue and PBO doesn't let cores go below a certain voltage. I'm not expert but I'd like to know if the CPU requests wrong voltage and fails or motherboard doesn't give enough voltage on stock settings. Obviously it's not that motherboard can't deliver enough because with PBO it can give the necessary power. I have a backup CPU, R5 3600. That one works fine at stock settings with AVX tests. Also I know these tests are unrealistic and probably there's no similar case I'd get in daily use but still to me that's an instability issue, you might disagree however. I have some screenshots and other stuff saved. Please let me know if you'd like to have a look.
Other hardware issues: Chipset temps are a little strange. Idle 78C and on full load it goes up to 83-84C. I see people are getting 60~... Don't know how. Even when I do a full blast with front fans the lowest chipset temp I get is 75C. I don't know if it would cause any issues. Just seeing a hardware constantly around 80C is a bit painful.
Software issues: This one might sound a little silly but SIV is the worst fan controller software I've ever seen. It is an absolute disaster. BIOS update app is OK.
Right, if I wrap up the whole thing, my experience with X570 Aorus Master is like participating a hill cheese rolling competition. It goes fast but tumbles and crashes very often, in the end it reaches to the bottom but is it really worth it? I don't know.
