Had it previously been booting with XMP on? Or did you turn it on, and now it can't boot? 

If the former, the IMC on your chip may have degraded from being run right around where its limit is, and you can try manually setting the highest freq it can run. You may be able to tighten up some timings at the lower speed, to claw back some performance. But yeah, 1000 series had kinda weak IMCs compared to later Ryzen chips. Big reason why it took until 3000 for Ryzen to really start to compete with Intel, because the mem speed affects a lot more on Zen than Intel.

The computer has been running fine for quite a while, but for some reaspn today it decided to say "cmos fail" and reset the bios settings any time I try to boot with xmp enabled.

Edit: this message appears on the one american megatrends screen when booting

Specs:

r5 1600

1600 and 1600af have weak IMC, You're lucky if you can get XMP to work out of the box at 3000-3200mhz, let alone 3600.

Even my 1700X can't do 3600 MHz. Try manually setting 3200 MHz.
