RTC Wake - Not Working

I recently replaced the motherboard in my backend and previously before installing the new motherboard I was unable to ping the lounge room computer from the backend but now I can ping it and I can ping the backend from the lounge room computer which solved one of my issues but the now I have an issue in that I can't get it to wake by RTC.

I have run the following:

echo 0 > /sys/class/rtc/rtc0/wakealarm

echo `date '+%s' -d '+ 2 minutes'` > /sys/class/rtc/rtc0/wakealarm

cat /sys/class/rtc/rtc0/wakealarm

cat /proc/driver/rtc

shutdown -h now

But it didn't wake up. On the old board it worked fine but not on this board. The old board was Gigabyte and this board is ASUS

I am running UTC for the time.

My motherboard has the most recent bios on it and has the following options in the power menu in the bios:

Restore on AC Power Loss
Power on From S5 By PME#
Power on From S5 By Ring
Power on By PS/2 Keyboard
Power on From S5 By RTC Alarm

I also have:

ACPI 2.0 Support
ACPI APIC Support

which are both enabled.

I can actually set a wake time in the bios and it will wake but I can't get it to wake by setting it from Arch.

Appreciate any help I can get to get this working.
