BIOS Settings reset?

[RocketSkatez]

I just noticed that my task manager was showing my ram running at slower speeds, so I checked and xmp was turned off. Does this happen often? I have not been on my BIOS for a long time, and this was the first I've noticed this happen. I did change it in the BIOS, but am curious if this has happened to anyone else.

I mean... could it be it was always off and you didn't notice till now?
I don't remember ever hearing of a self-resetting BIOS.

drained CMOS battery is a thing but we would have more problem than XMP resetting itself because of it. Another reason where it could be automatically disabled is if the BIOS designed to sense memory based crashes and it resets that, but that is board model specific.

CMOS would reset the whole BIOS. The only reason I can think of is if the selected XMP is incompatible for some reason and it resets to safe settings.

Do you maybe remember the name of the feature or an MB that has said "sensing"? I'm curious. What's the logic behind it and what exactly it detects? From what I know, "memory-based crashes" past the start-up are either bad software or physical memory degradation. The chipset has no awareness of the former and the latter can't be diagnosed without a memtest, never mind crashing periodically. 

 

Updating the BIOS is a good start for the author, imo.

Exactly my point.

MSI Memory TryIt is one that i used personally. Its less sensing and more like if it boot loops several time after XMP or TryIt preset is enabled, then itll just reset the settings.

Idk, from what MSi says it just automatically finds the best profile setting based on the RAM, and the "reset" happens when the PC can't boot with the current config. Did I get it?
Anyway, I assume that if there were any memory instabilities the author would've gone to the BIOS first. Simply resetting while everything's cruising is weird.

If you enabled XMP back when you build the PC and now just found that it is disabled, that is most likely because of a failed boot or any other instability, which then made the motherboard disable XMP. A RAM test would be interesting to run, both with XMP disabled and enabled. 

Could also just be a buggy BIOS. If you have any newer BIOS' available, consider upgrading the BIOS, then enable XMP and keep an eye on XMP in Windows going forward. 

Or if you wanna be really thorough, then first upgrade the BIOS, then run RAM tests.
