Bios flaking

[BTRY B 529th FA BN]

My bios has been flaky the past, well since I've owned it (my motherboard). I recently had to re-flash it.. could the cmos battery be going? And if so what stats for a cmos battery do I look for?

Thanks GH

most cmos batteries are cr2032(going by memory) should be able to look at it and it will tell you

But depending on what you mean by flaky a battery may not change anything. Unless you are loosing time, or settings are resetting to defaults

I recently tested out some RAM sticks I picked up from a purchase of an X58 platform and during boot things went fine, then when I installed my old sticks I started getting errors until I re-flashed the bios:

e.g.

The CMOS battery doesn't control anything about the actual BIOS code that's stored on the flash chip. It is responsible for keeping the volatile memory active, which means the BIOS settings.

If you run into the problem again, try going into the BIOS and reloading optimized defaults. If that solves the problem, then your issue is with the CMOS battery. If not, your issue is with the flash chip.

A few times it would revert back to defaults then boot a few good times and then one setting in the bios would flake the whole thing out again. I've re-flashed the bios and things seem to be fine so far.
