4770k instability since CMOS battery change

I recently did a CMOS battery change becuse my windows 10 times were always wrong when booting. I am not yet sure if that problem has been fixed but now I have a new issue. I was previously OCd to 4.3 ghz I think with all voltages on auto. Now at 4.3 ghz wiht voltage on auto or with core 1.25, cache at 1.15, initial and eventual input at 1.7... I BSOD within 1 minute of windows booting.I don't recall what my prior settings were... I honestly didn't t hink it would be that much of a big deal. Any idea why I have lost stability?Have a maximus hero VI motherboard.

Any thoughts on what I can do now to get back my old overclock and stability ?

Did you overclock it or the supplier if it was the supplier they may be able to tell you the settings or is there any setting to load mine is overclocked and the firm put a setting in the bios I just select 4.5 gig and its all set

There was no supplier, I built the PC myself. I did the OC about 4 years ago so I don't recall the settings. I think i just changed the core to 43 and left all voltage on auto.

I tried that of course and it didn't work.

As is well known, overclocking can be a crap shoot and it takes a lot of things coming together to get a good overclock. Changing the equation on one item relying on stable overclocks can throw things in a tizzy. Updating a BIOS is one of those things can can dramatically affect an overclock.

Bottom line is if you're an overclocker and your overclocked system is stable, think twice about BIOS updates. And for the record, I update my BIOS anytime a new one is released cause I'm obsessive like that. However, if I was a serious overclocker, I'd probably be more "selective" about BIOS updates as I'm now in the realm of testing for best stability.

And if you don't think BIOS updates can affect your overclocks, check this thread. Also a lot of guys there test beta BIOS's in looking for the best one giving the best performance.

All that said, a 4.3 overclock for a 4770K shouldn't be that hard. I did it on my Gigabyte G1 Sniper 5 board.

My two cents.

Hey I didn't update my bios. I only did CMOS reset by doing a battery change.

Did anything ring a bell in my first reply [#2]? Basically you didn't have to update the BIOS, just that if power is completely lost to the motherboard the BIOS will reset to its defaults. When changing settings in the BIOS those are ones changeable by the user and that get saved, not the default settings that came with the board which usually can only be changed by an update or restore. Twenty years or more ago we had to adjust settings for such things as time, date, HDD things such as CHS, Cylinders, Heads, Sectors before the computer would see the HDD. Then things started changing where the computer could be set to automatically identify the HDD, I have an MS-DOS 6.22/Win3.1 on hand with a bad battery [not made now] that has to have the time/date set every time but will identify the HDD without a problem, save the settings and the bootup will continue [for the few times I might need it not a problem].

Bottom line? Probably will have to get the BIOS back to its 'normal' condition and working then do the overclocking again.

What do you mean by normal condition?
