Does OCing Often Result in CMOS jumping?

post #1 of 6
Thread Starter 
OK, so I've had this build for a few months, non-OCed, and I think I might OC it. I know what I need to know mostly, but I'm wondering how often you have to jump the CMOS thing. On my MB it's just 2 pins, I guess I just jump them with a screwdriver head or something?

My question is, when you "mess up" Ocing, what happens generally? Do I have to jump CMOS every time, or will my MOBO (DS3L) just reset to stock? Thanks guys, I'd really like to get 3.0Ghz, but the AC7 and a bad mount might hold me back. My AC7 came with TIM, but the cracket was off and I had to jam it back on with metal tools I'd rather not go into. It smeared the TIM a bit and my load temps aren't what I'd like at stock. I have a max of 57/56/50/50 after a half-hour of small-FFT in Prime95. This is what proves to me I had a bad mount. Thanks for the help guys, REP+ for helpful responses!

not sure about ur board but if it does not have some kind of bios fail-safe
it will just sit on a black screen until u jump the cmos which will require u to leave the pc on its side through out the OC process ....

if ur board has some kind of parameter recall (like my sig board) it will reset itself when powered down so no need to even open the case

i would not use a screwdriver though...... if u have an old optical drive or HDD lying around there maybe a jumper just doing nothing on the back of one

Well, if you and I have similar BIOS versions (I think we do), the gigabyte DS3 boards seem to have a built-in 3-attempt restart before default bios settings are loaded--so if some setting is unstable and the computer can't POST for 3 times in a row, the BIOS defaults will be loaded (at least on my board). However, I noticed that the only thing that won't allow this to happen is if I have a RAM setting way off, or timings too low for the speed I'm trying to run at, this won't work, and the computer continually restarts and I have to clear the CMOS. But generally, if I can't get into BIOS due to a poor setting, by the third reboot the computer will default to POSTable CPU/RAM settings (usually the default ones), and you can get into the BIOS and fix what needs fixing. But I did notice that when this happens, I don't lose my other settings, only the OC settings (for example, my RAID options, etc. are kept and not reset).

Hopefully that clears things up. Sorry for all the text, I was just trying to be as detailed as possible...

I have the same board as you. What will happen is when set your OC and accept the changes the machine turns off and reconfigures. "IF" the settings are acceptable to the system to be stable enough to post it will. If not it will shutoff and install the stock settings for your clock speed and then post again.

This does not make your system stable, you still have to make it into windows and stress test. All this does is fail safe your system with a protection if it thinks your going too far, usually with voltages.

Your board does the same thing ours does, we just don't have the RAID.

Honestly, I've been OCing for over a year now, and two days ago was the first time I have ever had to hit the CMOS reset button.

If you research your OC and keep changes in small increments, you should never have to reset your BIOS.
