Performance Drop After Overclock

The pics pretty much explain it:

I don't know what CPU cooler you have, but it's possible that you've pushed the processor too far and it's throttling. Try a smaller overclock (like 50mhz) and see if you get the same results.

[timmage89]

Yeah I was starting to think that it's being automatically throttled down. I have the stock lga775 cooler.

Heres the results of a small oc:

I have the stock lga775 cooler.

That heatsink is not designed for overclocking. Prescotts are notoriously hot even before you overclock them.

[MadPistol]

Bad idea overclocking on stock cooling, especially on prescotts. If you're going to overclock that processor, you might want to get a better CPU cooler.

[timmage89]

If I got a better cooler would it fix my problem? Or could it be the voltage or something else causing it?

[Midknyte]

Mileage will vary from chip to chip, but enhanced cooling would probably help.

I don't mess with voltages until I max out a chip on stock voltage.

[MadPistol]

Voltage would not be a cause of what's happening. Voltage affects stability, but it has no effect on performance. However, if your voltage is too low for a sustained overclock, the computer usually locks up or restarts on a regular basis. If it's too high, the chip usually runs hot and it can shorten the life of a processor dramatically if it's set too high.

[timmage89]

Is there any way I can see if my processor is being throttled down?
