Easy Bios question

Yes, it could potentially require a BIOS upgrade. But this depends on A.) Your Mobo and B.) Your Current BIOS Reivision. Any recent mobo is not going to require an update. But if you have an older mobo, you'll want to look up updates specifically for that mobo and ensure that you in fact do, or do not require an update for fully functional SSD support. If you just flash the BIOS for an update, then yes, your OC will be reset. Several BIOSes allow you to save settings from one revision to the next, some don't. If you find you do need to update your BIOS (which I doubt it actually necessary), worst case scenario just write down the settings for each page within the BIOS. Unless the update is something absolutely major, you should have no stability issues by keeping your settings the same from one revision to the next.

As I mentioned, I doubt any update is required. Excluding some now very outdated boards, BIOS updates were generally only needed for certain brands of SSDs and motherboard combinations. I've only seen it necessary once in my personal experiences. SATA driver updates, or firmware updates for the SSD itself might be needed for maximum performance, but to actually update the BIOS is something I doubt would be required.

Happy to help, if you get a chance, let us know how it works out, I'm curious myself.
