Overclocking i7 2600k above 4.5Ghz - Page 2

Thanks for your input villain.

It's currently running a prime95 stress test and I have not encountered any issues but its early days. Temps haven't even gone above 69c yet which seems impressive.

Did you realize that CPU-Z shows your speed at 3.5GHz, and RealTemp shows it as 4.2? I would set the BCLK back to 100, and then check to make sure you have the Turbo Multipliers set correctly.

Edit: Instead of changing the CPU Clock Ratio, I would change the 1-4 Core Turbo Ratios. They should do the same thing on that motherbaord, but something doesn't appear to be working correctly.

The speed keeps fluctuating going up to around 4671 MHz. Should I still change it?

At the moment the turbo ratios are set to the below what would you recommend?

Once changed I assume I will need to decrease the clock ratio. If so how low would you go?

Just to add, I have also changed the BLCK from 1040 to 1000.

On most boards you change the overclock by changing the turbo multipliers. Gigabyte boards also have the CPU Clock Ratio settings, which normally acts the same way - so setting it to 48 should give you 4.8. However, that doesn't seem to be the case for you (based off the CPU-Z and RealTemp shots). So I would set CPU Clock Ratio back to the default (auto or whatever) and then change each of the 4 Turbo Ratio settings to 48 instead.

I would do one of two things either turn the turbo boost off or set the turbo to the same as your core clock.

Right ok I have change Ye ratios to match my CPU ratio (48x) and here is what I get within CPU-z and real temp. Is it best to set all values the same or just disable the turbo ratios and just set the CPU multiplier?

Once again, thanks for your help, it's really appreciated.

I think you should load the BIOS optimized defaults and then make your changes again. You've still got a BCLK overclock in that shot, so if you changed it it didn't take affect. Did you use the auto-overclocking tool at some point (either in the BIOS or the software)?

I would set the Turbo Ratios all the same (48) and not use CPU Clock Ratio, but it should work either way.

I did use easy tune yes when I was trying to get to grips with it. I have checked the bios and I must not of entered it correctly as I have re-done it and it appears to be correct now looking at real temp.

I have loaded the optimised settings and turned off all the power saving options in the bios and it looks ok to me now. What do you think?
