Core i7/X58 Overclocking Thread

[unclewebb]

Thanks for posting that. If the multiplier is dropping from 23 to 22 that's not technically thermal throttling, it's just the turbo kicking out.

I'm not 100% convinced that CPU-Z is correct though. rge provided me with the Intel documentation for calculating the multiplier for Core i7 and I worked with him to hopefully get this right. Neither of us have come across any documentation from Intel showing that half (0.5) multipliers exist for Core i7. They exist for 45nm Core 2 CPUs but not for Core i7. I'm not sure what CPU-Z is reporting when it reports this.

Here's a post from rge over on the XS RealTemp forum:

The Intel approved / recommended method for calculating the multiplier when the Core i7 Turbo is enabled uses timers located in the processor that CPU-Z does not seem to be using. RealTemp is showing the multi steady at 23 in both of your screen shots. We'll have to wait for a few more updates from CPU-Z to see what the truth is.
