I have a 2600K and I'm trying to overclock. First I turned SpeedStep off. My Vcore is set at auto so I only need to change the multiplier. When I changed my multiplier to 43 (for the clock to equal 4.3GHz), my Vcore automatically becomes 1.336v. I'm pretty sure everything so far is great.
My problem is that at whatever multiplier change (I went as low as 3.9GHz), (and my Vcore changes automatically and is sufficient), when I first turn on my computer, it turns off after 5 seconds and has to turn on again in order to boot.
People keep telling my that this problem is due to insufficient voltage, so I'm thinking, at what voltage (manually) should the Vcore be set with a multiplier of 43?

Please answer my question and help, I'm really getting stuck!

Voltages depend on the chip, some take more than others, therefore, often times you can't rely on the motherboards 'auto' setting. I would increase voltage manually, and when you over clock, leave the voltage at stock at first, then up the multiplier bit by bit, untill you see some instability, then increase your voltage slowly until your OC is stable.

I've figured out the problem, if you're familiar, it's the Asus (I have an Asus mobo) mobo's common problem: the double boot at a cold boot. I've searched many sites, and the solutions look very complicated to me.

To update the BIOS:

- Get a USB flash drive and put the BIOS file in it (that was downloaded from ASUS site)

- Go to bios and use EZ flash..

and then what happens???

You ollow the instruction for your Motherboard? IE finding the file on your thumbdrive, selecting it, ollowing through with the process. reboot, see i it solves your problem. i not, check settings.

Every CPU is different and will often require different voltages for different frequencies.

Read an OC tutorial in our Overclocking section for a good explanation on how to find out what voltage is right for your aimed overclock.
