Gigabyte X570 Aorus Pro BIOS resetting

Esoterick · 14 Jul 2019 at 10:26

As the title says I've just got this board and the BIOS keeps resetting.

When I go into the BIOS I am given this message:
"Clear CMOS Information
BIOS has been reset. Please re-config your BIOS setup items if needed"

This is happening when I restart the PC or shut it down and power it back up then go into the BIOS, without removing the power cable.

I've updated to the F4F BIOS, which I installed using Q Flash from the BIOS via a USB Stick.
Unplugged from mains then held power button down for 30 seconds then
Reset CMOS jumper by touching a screwdriver across the jumper contacts
Removed CMOS battery for ~5 minutes
Replaced CMOS battery with known working battery from previous motherboard

However I am still get the BIOS has been reset message, which is preventing me from enabling XMP.

Any ideas?

Ok I've just done a bit more fiddling. I noticed when doing anything in the BIOS, including just going into it and restarting caused an insanely long boot time(timed with a stopwatch at around 1 minute 30, to Windows login screen from a 970 NVME SSD) it gave the impression my PC is failing to POST a couple of times

The motherboard manual says "For optimum performance, when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR4_A2 and DDR4_B2 sockets." so I tried the other 2 sockets as a test and it's doing the same thing - i.e. not saving the setting and giving the Bios has been reset message when entering it.

What has fixed the issue is to not enable XMP under the simple mode and instead enable XMP Profile 1 in the advanced mode. My PC now boots into Windows reasonably fast and running "wmic memorychip get speed" from a command prompt now reports 3200 as opposed to 2400. I've then put the RAM back in the recommended slots and it's retaining the XMP setting and not giving me the Bios has been reset message. What is strange is how I had horrible boot times even just entering the BIOS to check settings and exiting without saving, since changing to XMP Profile 1 in Advanced mode this issue is cleared.

Unless for some reason you aren't allowed to change XMP settings under simple mode I suspect Gigabyte needs to look at fixing this.

For reference my RAM is an 8Pack 16GB (2x8GB) DDR4 PC4-25600C14 3200MHz Dual Channel Kit

Hopefully this helps anyone else who also experiences this issue.

The motherboard seems fine apart from that, pretty well made but I never really bother with any custom settings to comment on that side of things. The mouse cursor is depressingly slow in the BIOS though.

I've switched the motherboard fan to silent mode in the BIOS, but turns out I couldn't hear it anyway. Unlike the case/CPU fans.

Unlike my previous 6600k build(which was close to silent outside of games) the fans are nearly constantly running, but I've changed too many things to narrow down the cause just yet. Will see when the bracket for my Noctua DH14 arrives how much of a difference it makes. Either I have a noisy fan setup, I need to tweak my fan settings or the 3700X just runs considerably hotter.
