System properties - 2 CPU speeds shown?
I've just noticed the details in the attached screenshot.
Can someone explain why 2 speeds are mentioned? Googling didn't help

My i7 930 which is o/c from 2.8 to 3.8 shows :
i7 CPU 930 @ 2.80GHz 3.80GHz
which I guess is nominal vs actual. Since your i7 860 is nominal 2.80GHz, your snip suggests it is running below spec. What do hardware monitoring progs say about the speed eg CPU-Z, Open Hardware Monitor etc ?
Just to confuse things, my 2600K (3.4 o/c to 4.6) shows
i7-2600K CPU @ 3.40GHZ 3.39GHz
It's the speed at what the fastest your cpu can go, and the second is when your processor is idle and what it idles at. Usually.
It varies, I think it also depends if laptop or desktop.
Most modern CPUs will reduce its speed by lowering the multiplier and lower its voltage to conserve power when it is idle. Your CPU is currently running at 2.66GHz, but has a maximum frequency of 2.80GHz when under load.
The second speed usually refers to the actual speed of the processor, while the first is the "Rated" speed that the processor is designed to run at. You see this most commonly if the processor is clocked down to save power when idle. It is being word-wrapped to the second line because of the width of the window.

I am seeing different opinions however.

The first number is the specified default speed of the processor. The second is the speed the processor runs maximum in the system.
Thank you, guys.
I'm inclining towards the "idling speed" as described by andrew129260. Googling put this thread at the top!
It's a tower system. Device Management shows 8 cores at 2.80GHz. The BIOS shows:
BLCK 133.27 MHz and Turbo and non-Turbo ratios of 20.
If the figures did show rated speed and max speed in this system, what would cause the max speed to be less that the rated speed? What can I look at?

It all depends on the load on the system and the Power options you have set.
Mine is at a 100% all the time because I have a lot of cooling and I really don't care how much electricity it uses.
If the Max is set at (60%) at idle or light load you will get readings under the rated specs. Why your picture in the first post look that way I can't tell you. Could be a gigabyte motherboard.
My Windows show 3.7 - 3.7
This is what I run all the time. Idle or under load.

Could be wrong but to me it seems like normal and turbo ratings??

If you look at the specs you will see andas someone has already said probably down to what power you have it set to!!
