Why is my 2600K so poor?

[Digit]

Yeah that's it

Thanks. I'll give it go after and report back once i've give it some major testing

Edit: Well i've had a good few hours blast on GTA5 this afternoon and no problems at all. Just that little snippet of info you provided wazza seems to have done the trick.

Thanks for your help mate

My 2600k was running fine @ 4.6ghz up until recently.

I've had to increase the voltage and lower it down to 4.4ghz as I was getting all kinds of lock ups and crashes.

I've had to juice the ram as well so I think it's more a motherboard problem than anything else.

As others have said, ensure the Wattage/Power figure is increased. I just put in 250W in my Giga board (its a limit, not a set amount), but some 'boards will ask for an offset instead.

Wattage/Power is a function of voltage and current. If you increase one, so must you also increase the wattage!

I ran a 2600k at 5.0Ghz on an Asus P8Z68-V Pro. These are the key steps I used to get it stable at 1.42v. (highest seen in CPU-z using offset)

1. Update the Asus P8Z68-V Pro bios to the latest one. The later bioses helped with stability when overclocking. http://www.asus.com/Motherboards/P8Z68V_PRO/HelpDesk_Download/

2. Use the offset method for the voltage with a LLC of 'High'

3. Kept temperature ~ 75c max. Definitely no higher than 80c.

4. As Wazza states to bump the VCCIO up. I used 1.18v (go no higher than 1.2v)

5. I dropped the CPU PLL Voltage from 1.8v default to 1.65v.
