perhaps.
run your computer for awhile, and then re-boot, go into bios and check the cpu temp.
see if it corresponds then with what the asus program is telling you.
it may be different.
one way to be certain if it is windsor or brisbane is to go into cpuz, and if it says 90nm it is a windsor, if it says 65nm it is a brisbane.
if it IS a brisbane, that will probably explain the high temps...on am2 boards using the 65nm cpus, the temp readings are usually far from accurate for some reason using utilities. i havent found one yet that reads my 3600 correctly.
bios will be much more reliable.
lets figure out the temp issue is actually an issue, and then we can proceed with the overclock.
apokalipse and i can help you overclock it, no problem...once we find out if that temp is accurate. if it is, you are not going to be able to raise the voltage much, and with a windsor chip you will have to raise it to get a good overclock.
