intel dynamic acceleration? yes/no?

I just saw it as an option in the bios of a laptop (gs45 chipset). I looked it up, says it will boost the cpu clock frequency if one core is idle, so that single-threaded apps can run faster.

But it's available in the bios as an enable/disable option. So, what's the downside? The default on this laptop is "disabled". Is this just the typical performance versus heat output kind of deal?

I dont own one but I would just try it out and see if it is useful or not.

Turbo on/off

It's like asking the question "Do you want a fast laptop, yes/no?" Of course yes. But I have the choice, which means there are pros & cons.

Digging deeper in google searching it seems the choice is because of older operating systems that don't support these features well? Like XP and earlier?

Battery life could be a con.

Older OSes supports it. Only reason would maybe be some really odd old app.

This. If you primarily use that old laptop on battery power, you'll probably want to leave it off. If you primarily use it on AC power, you'll probably want to turn it on.

nm. Was thinking of dynamic storage acceleration

Yes, IDA was the precursor to turbo, same sort of thing. While normally it boosts while only one core is active due to a bug it can be activated on both cores at the same time.

Yes. Turn it on.

My Penryn boosts from 2.4 to 2.6 under light loads.

Yes. It's like turbo on newer models, just to a far lesser extent. The difference isn't big enough to impact battery life at all, and there's the "hurry up, get idle" aspect of it.
