Never really overclocked. Got a newer board, and felt like I'd give it a try. Not really using the best hardware. So far, I feel as if I got a decent clock for what I have. Current temps don't go higher than 33*C idle, 44*C under load. Working with an Athlon X2 4050e, 4GB DDR2-800 ( 4 x 1GB), Asus M3A76-CM. Once I get some more thermal paste, I'll put in my 7750 and see what I can get. Stock runs at 2109Mhz, current is 2818Mhz. Good so far? I can't go any further, at least with what I know about overclocking. I'm very happy with it.
