I went to BIOS, set turbo multiplier to 43x, and the other thing to 100. That's all I changed. Then I booted the system, started SpeedFan to check temperatures and CPU-Z to check core specs.
After that I ran Intel Burn Test on standard stress level 10 times. The clock of the processor increased from steady 1.6 to 4.3 GHz and core temperatures started to rise (maxed at 91'C). After 254 secs the burn test was succesfully completed. The average time for one output was 19 secs, with the speed ranging from 45.5 - 47 GFlops.
Then I ran it on very high stress level, it took 225 seconds for only one packet, with the speed of 34 GFlops, after which I stopped it, because it was taking too long. The temperatures this time were lower (86'C max).
One thing I found curious about this is that the temperatures went down from almost 90' to about 65'C in just one second after the test was finished/stopped.
Did I overclock it properly, and do I need to change anything else? The speed of 4.3 GHz is enough, so I have no need to overclock it any further for now.
EDIT: Just to note, when I ran the test, I didn't close any of the background programs that I never close (Microsoft Security Essentials, nVidia Control Panel, Winamp, Steam, and a few others), so that I could see if it was stable even with all of them running.
