I am not au-fait with overclocking/unlocking, but have just bought a cheap new motherboard/CPU Combi £50.00
Motherboard Model: ASRock N68C-S UCC
CPU: Sempron 140 2.7 GHz 45 W July 2009 SDX140HBK13GQ Sargas Core
In the Motherboard BIOS I have enabled the UCC Option http://www.asrock.com/feature/UCC/i… and now have a:
Athlon II X2 4400e 2.7 GHz Regor Core
I have googled and it seems to be satisfactory to do this, but would like a second opinion, thank you.
By the way I am using 2 x 2GB Crucial PC2-6400 Memory, which I believe is OK !
I heard energy efficient e series are good overclockers, may be u can try to push it further.
Unlock it & overclock it!
