What is default BCLK and Turbo Ratio for Intel Core i5 2500K?

[Tempstar]

I just build a new system with an Intel Core i5-2500k and an Asus P8Z68-V PRO motherboard. However, I am having trouble booting. The system will reboot itself several times on startup, and then say "overclocking failed!"

I went into the Advanced BIOS menu and I saw the following:
"Target CPU Speed 4326 MHz, Target DRAM Speed 1372 Mhz".
Ai Overclock Tuner was set to Manual
BLCK set to 103
Turbo Ratio set to 42.
I tried resetting the Ai Overlock Tuner to AUTO, but after rebooting it set itself back to the setting above.

I am not planning on overclocking this system. How do I set the system so that it stays in a non-overclocked state? What BCLK and Turbo Ratio do I input? Anything else I should set to disable overclocking?

I know the Z68 is fairly new, but if you have a P8P67 variant and can provide advice, I would appreciate it (settings should be similar).

I'd reset the CMOS if you do not intend to overclock. This should resolve your issue.

I tried loading the BIOS to factory defaults, saving, and rebooting, and it still comes up with the values that I posted.

Factory defaults and reseting the CMOS is not the same. If your board arrive with a multi set for an overclock, the board may leave the multi as is.
Reseting the CMOS should handle your issue. Chapter 2.2.7, page 2-20 of the Manual.

Or just set the overclocker to 'off' or 'manual'

Stock settings: Intel® Core

Multi 33, Turbo 37.

Tried both, and after loading factory defaults, it still comes up with an overclocked value.

The BIOS just gives me the following options:
- BCLK/PEG Frequency -> do I set this to 100? Something else?
- Turbo Ratio - by all cores: -> do I set this to 33? 37?

It doesn't look like there is a single setting for disabling overclocking. There is:
- Internal PLL Overvoltage
- CPU Ratio
- Turbo Mode
- and a number of voltage settings for CPU, RAM that are currently set to Auto.

Just a question, if you don't plan on overclocking why did you get a z68 mobo and an unlocked CPU?

[Phill]

with the computer off and the power cord unplugged from the PSU have you popped the mobo battery, given it a few min and then put the batt back in?

I got the answer. The default BCLK is 100 MHz, and multiplier is 33. Once I set this the system boots up fine without multiple reboots first.

Thanks everyone.
