Sempron 140 Gets Second Core Unlocked

We love getting more chip for our money. That's why we're into overclocking. But an even more interesting way to get more performance for free than overclocking is to unlocking extra cores.

We've seen core unlocking from the AMD Phenom II X2 and X3, but now it seems someone has figured out that the Sempron 140 can also be unlocked to restore it an Athlon II X2 state. Both chips are based on the same silicon, but the Sempron has one of its cores disabled.

If this feat is easily replicated, this could be the cheapest and most full-featured dua core processor for $40. Even better if you can overclock it too (which that same modder did, going from 2.7 GHz to 3.7 GHz).

    As with anything, don't count on this working with your sempron.

    However, according to the site, they used a 790GX with ACC. I would think you could get a cheaper motherboard, and buy a Athlon X2 you know will work properly with both cores enabled. Seriously, who's going to spend money on a 790GX but buy a $40 Sempron and hope they can get both cores working?

    If you can do that and keep the power envelope the same that would be amazing..

    Which motherboards can unlock the second core on a Sempron 140? Any of the AM3 785s?
