Unstable overclock... should I increase voltage?

Hi All,

I'm very new to overclocking but have overclocked a couple of PCs a few years ago with success.

Ive just got an IvyBridge i7 3770k which I'm trying to overclock on a Gigabyte z77-dh3 board.

I set the clock speed to 4.4 which I had read in a few places is an expected overclock without upping voltage. I couldnt even get this to boot so i dropped to 4.2 which booted but kept producing program errors when under stress (like transcoding video ect)

So based on this, should I now try and up the voltage slightly? My temps seem to be goo at around 36c idle an 50c under load.

Thanks for your help.

Anyone?

Is the voltage on auto or have you manually set it?

If you have manually set it try setting it at 1.2V and try again at 4.2GHz (you may need to go higher after testing).

#thanks. No its just been left at whatever the default bios sertting is. I'll double check and post back.

Bit of an update then.

Running voltage at 1.2 (although CPU-Z says its only 1.164) with the clock now at 4.2ghz and it seems stable on a short prime95 test.

I'm getting temperatures of 64c when under stress. Is there more room to overclock still? I tried 4.4 on the same voltage but prime95 wouldn't even run, it just crashed out.
