    As far as I'm aware unless you saved your bios settings as a profile then unfortunately not.

    If there is no backup, then no.

    If it's a pre-built system, then look on the vendor's website.

    You could consider upgrading the bios to the latest, once you're sure everything is working correctly, just be aware that a failure to correctly install a bios can kill the motherboard.

    I deal with CMOS battery failures all the time; unfortunately there is no recovery for the lost data. Odds are the CMOS data was gone the minute the battery depleted. Theoretically the data could be stored on a hard drive, but you would still need to somehow read that data to restore it. Which means you'd still need to enter all the CMOS information.

    If you haven't done so already, you will need to replace the battery or enter the information every time. That is if the system even boots without the battery in place (some will, some won't).

    At least the coin batteries are cheap and you should be able to pick one up at Walmart or any drug store. They are pretty universal.

    I would be careful with the memory speeds. Mis-configuring them could damage the system if you do it for too prolonged a time. Check the speed of the memory, as well as the speeds that the MB can support.

    i think i can do it from memory, for the most part, but did not save a profile. yeah, it would be good time to update BIOS. There is a new one available. Need to check video drivers too. 
    I had the memory overclocked, but I'm going to try DS to see if it really matters, although it would be good to have my memory at its purchased speed of 3200 instead of default 2133mhz. How much of a difference is that in overall speed in applications actually? 

    XMP profiles are stored permanently. You won't need to manually input timings or anything, just pick the XMP profile.

    If its an Intel CPU that will have a modest effect on performance, <5%. If its a Ryzen CPU the difference could be quite a lot more, between 5 and 10% of a boost.

    and if the timings are wrong the motherboard will just reset to 2133. no damage will occur. The UEFI's are far too advanced to let you damage anything with bad timings.

    It may or may not help but often these BIOS are similar between manufacturers. My computer, after a BIOS update recently to my B450 MB from Gigabyte, wouldn't boot. They somehow messed up the correct ability for the BIOS to cycle through the list of possible boot devices and my PC would not boot consistently either off the SSD. Somehow it was the USB they messed up but I never investigated further. They've had problems with USB before with this MB. I rearranged the boot devices, saved, and that fixed it without changing any other bios settings.

    it would be interesting to klnow why happened.. maybe you left it attached to an active socket and there was some sort of surge?

    not much difference to justify the money if you have to buy them just for this reason..
