Help with i7 OC

sydeccles · 24 Sep 2012 at 09:14

My set up is
Intel i7-2600k Retail CPU
Gigabyte GA-P67A-UD4 B3 motherboard
Kingston Hyper X 8GB 1600mhz Kit
Noctua DH-14 Cooler

I bought the system it was running at 4.6 GHz,

The PC has been left for several months and not plugged into the mains, anyway came to use it again and the mobo battery was dead, fitted new battery, fired it up and the cmos/bios had to be reset, so I am now back to std - i72600 3.4GHz running at 3.7 GHz.
I have tried and tried to put an overclock back on with a 100% failure rate, I cannot get any overclock to work.
I have tried to follow this, but it does not work for me

ANY help would be appreciated

Could you not go back to the supplier and ask if they have a record of the settings that they used for their standard 4.6GHz overclock?

As PieEater said above +1

Also, are you manually setting your ram timings and frequency?

Thanks for the replies.

I bought the systen on members market in Dec 2011

I will E Mail the guy, see if he can remember the settings

The problem is I am most likely doing or not doing something that is obvious to everyone but me.

Couple more questions

Getting there
Finally got my i72600k to boot with a multiplier of X43 anything more and BSOD

Settings so far
Cpu volts1.3
Memory Voltage - 1.50v
BCLK Base Clock 100

Questions / Advice on the following

Internal CPU PLL overvoltage on Auto ?
Multi Threading Disabled or should I Enable ?
Real time ratio change in OS – Enable or Disable?

Thanks

Set your ram timings and frequency first. You should be using 1.5v, 1600MHz, 9-9-9-27 2N timings but check this yourself.

Internal CPU PLL overvoltage on Auto ? Enable this

Multi Threading Disabled or should I Enable ? Enable, if not you might as well of saved some cash and bought a 2500k

Real time ratio change in OS – Enable or Disable? If you want to keep your cpu running at 4.3GHz even when you're not using it leave this disabled. If you wan't the cpu to drop to 1.6GHz and only boost to 4.3GHz when in use enable this option.

After setting these try x46 multi @ 1.36v and see how you get on

Memmory will run at 1600MHz 9-9-9-24 1t with or without XMP enabled & Channel interleaving also Rank interleaving on auto

both settings show 7.8 in Windows Experience Index.
No can do X 46.
