Could updating my BIOS cause a stable overclock to go unstable?

post #1 of 9
Thread Starter 
I have been trying to successfully overclock my new build for nearly two weeks... and finally got it working stable at long last.... but during the time it took me to do this a new update for my motherboard was released.

I know there are lots of people who feel you should never update unless there is a problem and others who feel you should use the latest patches for your software. Personally, I at the very least like to keep my OS and firmware/bios up to date.

Thing is, I would have to lose all this hard work. I just wanted to know if there is any (realistic) chance that updating my motherboard's UEFI after finally getting my overclock stable could cause stability issues with it?

I've never had a problem... and I suppose you could always roll back if you had to - just make sure to write down all settings - I prefer to use a camera to take pics and video of ALL of the settings in the BIOS so that I don't lose anything. Flashing the BIOS will can all of your settings so don't be a n00b and forget to document them!

Loosing settings shouldn't be an issue, the BIOS has a feature not only to save screenshots to a USB drive but to save different profiles of settings to internal memory and even export these profiles to a USB drive as well.

I wouldn't count on the "save settings" feature working between BIOS revisions. I said what I said for a reason - And again, I would definitely record the settings VIA screenshots of some sort before flashing the BIOS.

Don't know about stability with the clock, but the last time I flashed I destroyed windows. Will never do it again unless I have to.

New updated bios are usually the same as the previous bios with some new fixes, but every once in a while you do get updated to find it needs a bit more voltage here or less there.

I will usually not update a motherboard bios unless there is an issue I can't solve another way. Old bios is incompatible with my memory kit & a new bios has memory compatibility listed in the fixes is worth doing.
If I'm not having any issues with the bios, I don't try to fix it if it isn't broken. A bad mobo flash can be a nightmare.

Flashing the BIOS shouldn't have "destroyed windows" by any means - it's more likely that you had something like AHCI enabled and when you flashed the BIOS, it switched back to IDE - which prevented your computer from recognizing how to boot from the OS install on your HDD. Flashing a BIOS from the BIOS itself has absolutely nothing to do with Windows.

That said, don't flash unless you have a damn good reason to - it's not like a simple software update and lots can go wrong even if it's done "right."

Well that happend to me once,kinda...I thought i was stable 4.5ghz 1.24V offset +0.005V and i was at Bios 2.0 and then i updated to 2.5 and with the same settings i was getting random BSODs.It turned out the LLC was the other way around after the update.Level 5 was highest Vdroop,now it's none Vdroop.After actually realizing this,i was able to reach 4.5Ghz stable @ 1.216V weirdly enought...Before i had just +0.005V and now i have +0.005V and turbo voltage +0.004V and for some reason it's lower.I tested it out with every program possible and it seems that it gets to 1.24V as it was before only when IBT/prime-ing.While gaming,1.216V.Before it was 1.24V while gaming and while stress testing.

Pretty much this. A BIOS flash can certainly tweak your need for voltages here or there. I've had one or two flashes that completely revamped my LLC settings. 1-10 were all completely different and they even added in a few levels once.
