I have an Intel Core i7 860 that appears to be running at a much higher than 2.8ghz speed. Windows is extremely slow starting and runs very choppy. Some games seem to run while others frame rates make play impossible. I ran SiSoftware Sandra and it says the clock speed is 8.31ghz. I've restarted several times checking the speed and get speeds ranging 5, 6, and 7ghz with 8.31 being the highest. I do not run or have any overclocking software. anyone with similar problems or insights on how to fix would be greatly appreciated.

More about : runnig higher rated speed

I would grab cpu-z and hwmon to see what speeds you are running at as well as the temps.

If the temps get too high, the system will slow down to try to save it self from overheating.

Thanks for the links

Speeds are still high and temps seem to be normal except for the motherboard. Its showing 128c or 276f. Perhaps the motherboard is failing, I've already had to replace it once.

128c is generally a sensor that is not connected and HWmon does not know what to call it.

How high are the speeds in cpu-z?

Closest to your I have is this

Idles at 1200 or 1199 sometimes maxes at 3200 because of turbo.

cpu-z says between 3300 to 3400. mutiplier at 25times

That is fine(3.46ghz give or take is normal for that cpu under single threadded loads). Your system must have something using the cpu OR power save settings off.

My cpu(closest I had to yours) is a lower model so does not have as high of a top speed.

Reset bios to default and see if that helps.
But before doing that you want to validate it with CPU-Z so you're ranked #3 in Intel's highest world records! :D

I have the power setting set to high performance in windows.

I just ran a stress test using Intel extreme tuning utility. core temps jumped to between 87c to 99c over the 4 cores. The utility said passed.

Have tried that several times doesn't seem to affect the problem.

Update your motherboard bios
Check your CPU cooler, make sure it's secure and none of the push pins or screws are loose or broken.
Remove the CPU and reinstall it, while it's out check for any signs of damage or bent pins.

use netstat -ano and look for "established" connections, then look up PID via task manager to see which process it's coming from.
If none of the visible PID has established connections, but netstat -ano says there is, then your system has a infection of some sort.

Core temps that high mean your cooler is A. Clogged with dust OR B. Not installed right(extra heat can lead to thermal throttling[slows the system down]).

Intel's stock cooler is not great, but should not get THAT hot. I would guess 70-80 tops.

You may pass, but with a stock clock speed you should pass.

Please check for dist in the fins on the cooler and blow it out with compressed air if needed. do NOT remove the cooler unless you are ready to apply new thermal paste.

What are the idle temps anyway?

If you change you power settings to Balanced it should clock down at idle. It will clock up when needed still. That is generally the best setting for most users.

idle temps are at 50c at cores

I have a 6 pipe copper cooler with 2 92mm fans. temps at cooler are 36c
Just replaced all the fans in the case to try to remedy the problem last week. also cleaned cpu cooler and applied new paste (artic silver).

Have had this CPU since it was released just started having these problems in the last few months.

What are your voltages? If they are for some reason high you could get extra heat as well. I found that generation of chips under volted quite nice too.

If you have remounted the cooler, that should rule cooling out.

vcore seems normal.

I see no reason for high temps.

What cooler is it you have? if it is a push pin, could the pins have not made it in all the way(if they do not get out the back of the board, the contact will not be good.).
