Third Core always on high load (solved)

[mist303]

Hello all,

I have a Xeon L5420 running between 2.5GHz and 3GHz (depending on total load). The total and per core temperature is very acceptable (55-60 C at max load) so the core isn't going on throttle (tested on AIDA64).

However, the third core seems to run between 70% and 98% loads (never less) while others vary very normally.

Here's a screener of what one of my gadgets reports:

Some of my PC specs are:
Gigabyte GA-EP43-UD3L
Kingston DDR2 2x2GB ram @400 (or 800MHz)
Windows 7 Ultimate (64bit)

 

[[Ion]]

If you open Task Manager, go to the Processes tab, and sort by CPU usage, what does it report?

Tune-Up utilities was running integrator.exe for no reason. (task manager didn't show it, used Processor Hacker).

My baaaad. Thanks
