Overclocking help for I5 2500k Sandy Bridge

post #1 of 18
Thread Starter 
So I am trying my hand at overclocking, I am completely new to this. I installed a CoolerMaster 212 Plus, downloaded Prime95 and Speedfan, and am ready to go. However I am having trouble with the BIOS.

Basically the person who explained OC to me told me to set my "Turbo Core" to 42, and give that a try. However I can't seem to find an option in my BIOS called "Turbo Core". I think I have an older BIOS version, but here are my options in the Processor Overrides section, I bolded my current choices:

CPU Voltage Override Type: None/Static/Dynamic
Maximum Non-Turbo Ratio: 33
Processor Idle State: High Performance/Low Power
Intel Turbo Boost Technology: Disable/Enable
TDC Current Limit Override (Amps): 97
Burst Mode Power Limit (Watts): 118
Sustained Mode Time (Seconds): too many options to list, but currently set as '1'
Sustained Mode Power Limits (Watts): 95
IGD Current Limit (Amps): 32

Active Core-Based Ratio Limits: Disable/Enable
4-Core Ratio Limit: 34
3-Core Ratio Limit: 35
2-Core Ratio Limit: 36
1-Core Ratio Limit: 37

So which of these would I change to get the equivalent of setting "Turbo Core" to 42?

fill out the rig builder part of your profile so we can see what mobo you are using along with the rest of your hardware so we can give you a more in depth explanation versus a general regurgitated one.

it's the maximum Non-Turbo Ratio, however, if you want to increase your multiplier ratio, you'll probably need to increase the voltage cor the cpu too. which motherboard do u have?

oh... and you posted in the wrong forum, but yeah, I'll ask a mod to move it and tell us your computer specs.

here's a thread you should read:

Intel BOXDZ68DB LGA 1155 Intel Z68

I tried to change the Maximum Non-Turbo Ratio, but it keeps going back to 33 automatically.

If you fill in the rig info we can get a better idea on how to help you OC your 2500k.

With that MB I would only go to 4 GHz at stock voltage.Is that MB a 4+2 power phase?And are you using the stock Intel CPU cooler?

oh wait motherboard duh. i have no idea about the power phase, where can i look to find that out? oh and i have a 750 watt power supply, so increasing voltage anywhere should not be a problem.

Its the VRM'S that you have to worrie about are there heat sinks on them?They would be on the left next to the CPU socket.
