abit intel chipset mobo's are usually way off in their temperature readings. i think your temps in this case are fine, considering mine peaks at 52 degrees with the strongest p4 air cooling you can get (which i know is off because my sensor right under the die says much less) As for overclocking, your ram is probably holding you back going any further. Try upping the vcore until its stable, but u dont wanna go too much, cause im still not exactly sure if those temps are accurate or not.
