I am preparing to overclock my i5 2500k processor to 4.5 ghz using the touch bios program which is compatable with my gigabyte mobo.
Before I go through with this I was wondering if anyone knew how I could reset everything back to the default values should something not go as planned
I understand that to reset the bios I can pull some sort of CMOS battery from the mobo and that should reset everything to default values, is this the only/best way?

You also always can reset your BIOS when you enter your BIOS. BUT if you OC'd so hard, that the pc wont even turn on, you have to do a hard reset with the CMOS.
Some mainboards even have a small switch to OC and/or reset your BIOS.

I have a GIGABYTE Z68MA-D2H-B3
Just failed an overclock due to some voltage settings and now I cant find CMOS battery TT

Truth!

Ive pulled the cmos and such for like 10-20 minutes. But the OS still wont load. It starts to load then flcks to a blue screen really quickly and restarts bringing me to a screen where it asks if I want to attempt a repair or start windows normally.
Ive tried the repair but it still results in the same issue
|
Also enter BIOS and try loading optimized default
wait wait...your OS != BIOS!
Where did you overclock your CPU voltage? in windows using some tool or in your BIOS?
If your PC goes through the BIOS bootscreen without giving an error, the reset was successful. If your Windows give you a bluescreen your windows-installation is damaged and/or some settings in windows make the loading impossible
|
If the problem is windows based booting in safe mode could help(press f8 as soon as win starts to load if it is win 7 and choose safe mode)
|
i think Touch BIOS is windows based ? (i might be wrong)
btw, before you overclock, do u have proper cooling device for your processor, especially if you're going to 4.5ghz.
|
If the OS isn't loading with OC settings active, you can try either repairing windows or changing your OC settings to a previous point that worked and loaded your OS. I'm OCing my own i5 right now and simply taking one step back to earlier settings allowed me to get back in windows whenever I couldn't.

Yea, I was going to try it within the bios this time anyway
Wouldent different MOBOs have different bios formats?
Will everything in the guide be the same for my mobo/bios?

It will likely be fairly similar, but not exactly the same. Even mine is different from this guide but if you just take your time and look carefully you'll find everything you need.
What kind of cooling system do you have, by the way?

Looks alright. Keep posting updates as you make progress, I'd like to know how well this fan works mostly, so give me temps!!

Will do, One thing. Im loking through the guide you gave me and I dont see the i5 2500k as one of the cpu's they listed @@
Is it still ok to follow this guide?
Also, I have no clue how to access bios >< I am computer noob

Your CPU isn't an 1156 socket, so it won't be on this specific guide, but if you want anything extra just double check the numbers they give you in this guide with your CPU's specs on intel's website. Most of it will likely be the same, and the steps to overlock will be the same for sure.
If you can't access the BIOS I'd recommend getting someone to do this for you...

Ok, so this is where my issue arises from the guide I am using here: http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4
From Advanced Voltage Settings
Load-Line Calibration gets enabled, then plug in your voltages: a CPU VCore of 1.3V, a QPI/VTT (otherwise known as the VCCIO) of 1.12V, a System Agent Voltage (aka VCCSA) of 1.135V and a the usual 1.65V of DRAM Voltage. You can type these values in directly, but Gigabyte jumps between 0.01V and 0.02V increments on different settings, so you might need a bit of cursor-key fine-tuning.

This may change again in future updates, so remember to double-check your your overclock if you update your BIOS or receive a board with a different revision. A bit of smallfft crunching in Prime95 and three loops of our Media Benchmarks should do.
Quit the voltage menu all the way to the main menu where you should next select Integrated Peripherals. Set the PCH SATA Control Mode to ACHI (or RAID if you're making an array) and leave the options alone. We've disabled the the eSATA 3 Controller and Onboard Serial Port 1 because we're not going to use either.

I don't think you need to tinker with sandy bridge that much to get to 4.5 GHz, maybe just try leaving everything at auto and just step up vcore bit by bit(prime)?
I don't remember perfectly, but I think all I did on my 2500k to get to 4.5 GHz was disable speedstep to keep multiplier at 45x, llc on, vcore 1.375v
