My CPU is running too slow and I don't know why.
Testing my PC with Prime95 and SuperPI software, looking the performance with CPU-Z I got the following numbers:
Core Speed: 800 MHz
Bus Speed: 100 MHz
Sometimes the multiplier goes from 8 to 35. 30% of the process stay en 16 and 68% in 8.
My hardware is:
Motherboard ASRock Z68 Extreme3 Gen3
Bios version 3.20
CPU Intel I7-2600k 3.4G 8M
Water Cooler Kuhler 620
RAM G.Skill Sniper 16 GB (4x4GB)
Graphic Card NVidia GeForce GTX 560 Ti 1GB
PSU Rosewill Hive 650w
Windows 7 Home Premium 64 bits
The PC is running in standard way, no overclocking.
In the Bios says the CPU is I7-2600k @3.4GHz running at 3500
I appreciate some help.
The most likely cause is that your cooler isn't seated properly. I'd take it off, clean it, re-TIM it, and reseat it, making sure that it gets tightened down all the way.
You were right. The problem was that the cooler wasn't seated properly.
I had to clean, to buy a thermal paste and assembly the cooler again.
Now the tempertures are between 36 to 40 Cent Deg and I culd OC the CPU running 4.4 MHz
Thanks for yor quick answer, for help me and share your knowledgement.
