Hello, my RTC keeps changing time after 30 minutes after reset. My Z87 board come with my system that I bought. I have tried all the windows fixes with no luck. As suggested on this forum I am going to change my CMOS battery while in standby mode. I was just wondering if the battery change will change my factory overclock? If so then I should record all settings in BIOS to re enter after battery change. I sure hope the battery change fixes this. Been on this for 4 days now and is getting old. Thanks Any help appreciated.
