I've been having an issue where my BIOS occasionally resets my RAM speed from 6000 MHz to 4800 MHz. This hasn't happened too often, maybe once every couple of months. The bizarre part is that it doesn't seem to affect anything else—date and time stay consistent, and the system boots up normally. I'm wondering if this could be a sign of a failing CMOS battery, but I've only had it for about a year and a half. When my RAM runs on XMP, everything seems stable. Could someone help me figure out what's going on?

It sounds like your CMOS battery could be fine since it's not resetting all your settings. If the RAM speed changes only occasionally, it could be due to a boot issue where the BIOS fails to load the XMP profile correctly sometimes. Watch how it boots—does it take longer occasionally? That might indicate it's having trouble at startup, leading to the speed reset.
Just because the battery is only a year and a half old doesn’t mean it can't fail. Some batteries can die unexpectedly. But it's interesting that it doesn’t reset everything else—sounds like a quirky issue with the RAM settings or boot process.
Right? I didn't think they could die that fast either. Might have to look into getting a new one just in case!
Yeah, my PC does sometimes take longer to boot up, and that's when I notice the speed drop. Otherwise, it usually boots fine with the right settings.
