If the same 4 sticks of RAM worked in that same motherboard before the CPU upgrade, I don't see how this can be caused by RAM.
That said, I do not see where the OP ever said it has ever worked with the full 32GB (4 X 8GB) installed at once. Has it?
Corsair Ram, not a truly amd tested brand.
Please explain. I note there are more than 3 dozen Corsair RAM models listed on the QVL for that board, including several 4*8GB kits.
I agree with the suggestion to reset the BIOS however.
I’m going to take out the cmos battery and let it sit for the last hour
Unplugging power from the wall (or just flipping PSU's master power switch to off or "0" is fine), then pulling the motherboard battery will reset the BIOS. But there is no need to let it sit for 1/2 hour. None of the caps on the motherboard are designed to, or are in circuits that store voltages. Even if there were storage caps in there, the "low" DC voltages found on motherboards have such small potentials, the "decay rates" would quickly (within seconds) drop the voltages below any viable levels anyway.
It is important to remember CMOS circuits and CMOS memory devices
by design are intended to dump all data within a couple clock cycles after losing power. And CMOS devices were intentionally chosen for that reason by motherboard and BIOS engineers/designers to make the BIOS easy
and quick to reset. Had the engineers/designers wanted resetting the BIOS to be more difficult, or for those user changes to the BIOS firmware defaults to be more "robust", they could have easily (and less expensively!) done that by using different memory devices for that circuit - like EEPROMs instead of CMOS.
So unplugging and removing the battery for 15
seconds is plenty. Only the PSU has such caps that store voltages and they have bleeder circuitry designed to quickly bleed off their voltages to quickly eliminate any "high" voltage electric shock hazards. This is why simply shorting 2 pins by moving the BIOS reset jumper for a few seconds (or, if the motherboard is equipped, pressing the reset button for a few seconds) is plenty enough time to fully reset the BIOS.
Note your motherboard manual on page 1-9 says under section 1.1.6 Jumper, "1. Clear RTC RAM jumper (2-pin CLRTC)" (my
bold underline added),
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5 - 10 seconds.
So more than those few seconds is just wasting your time. Just be sure to discharge any static in your body by touching bare metal of the case interior BEFORE reaching in for the battery. And once you replace the battery and reconnect (or flip on) power, be sure to boot directly into the BIOS Setup Menu to check/set the date and time, and ensure your boot order is correct (if not using the default C drive).
