r/buildapc on Reddit: How to clear CMOS?
May 1, 2021 -
I while trying to upgrade RAM in this prebuilt computer ( https://www.bestbuy.com/site/asus-rog-gaming-desktop-intel-core-i7-9700k-16gb-memory-nvidia-geforce-rtx-2080-super-2tb-hdd-512gb-ssd-black/6401068.p?skuId=6401068 ) I changed the XMP profile and now the computer won’t POST at all. I’ve read about this issue with other PCs and it seems the solution is to clear the CMOS. However, there is no manual that came with this motherboard and I’m trying to find out how to do this properly.
Edit: there was a CLRTC pin that we were able to use to reset the CMOS. Thank you all for your quick suggestions.

First try and identify the make and model of the motherboard and download the manual which will tell you what you need to know. If you can’t then use a torch (flashlight for my North American friends) and examine the motherboard closely for a jumper labels “jbatt” or “CMOS”. If all else fails unplug the system, hold the power button in for 20 seconds then pop the CMOS battery out of it’s holder and short the centre spring contact underneath the battery with the side contact using a screw driver or tweezers for 20 seconds, replace the battery and try again.
