i5 cpu's have the turbo boost feature. Does this feature work with Mame ?

My question is does Mame make use of intel's turbo boost feature ? My friends 2500K is clocked at @3.3GHz but at turbo it's @3.70GHz.

Yes, it works. I think the Turbo only boosts one core though.

Software doesn't have to be written to "use" the turbo feature. Under sufficient load, the CPU just ramps up to the turbo frequency on its own.

Turbo works on all cores at the same time but the top turbo frequency depends on the number of cores that are active...




Incidentally, you can overclock the 2500K. Mine is stable at 4.5GHz with an aftermarket cooler.
