Adding Intel Turbo memory later

Turbocache is a pseudo hardware/drivers method of using the built in memory on the video card to cache data stored in regular ram. It isn't really a hardware addon, it's a driver enabled feature that will add a very marginal performance boost(the amount of that performance boost is arguable, although there is no argument that it does not harm performance to have it enabled).

You cant add it onto a laptop that doesn't have the feature in the chipset already, but you are not missing much by not having it.

Thanks for writing back. I may have used the wrong terms, though. I'm talking about the Robson technology implemented with the new Santa Rosa Intel chipset. I'm trying to decide between a D630 and a Thinkpad T61. On the T61, one of the configuration options is the 1GB Intel Turbo Memory hard drive cache, which is a $50 upgrade. (I believe it's some sort of flash memory card) However, I've read that if you don't include it in your original configuration, you can add it later on the Thinkpads. I'm just wondering if the same is true for the D630 since it isn't available on the current configurations (but the chipset in them would support it). On the D630 specs, they mention Intel turbo Memory cache technology cards take up one of the available Mini-Card slots, so clearly there's some piece of hardware to it. I know the early evidence is mixed on the performance, but it seems like this might have to do with the early units not working the way they're supposed to. Just trying to cover all my bases before I take the plunge.

ooh, I just recently read about that - it looks like it will make a BIG improvement in Vista performance. I would definitely make sure it includes it if you are running Vista.

I think I just found the answer. Card goes in any PCI-E slot (Dell's WWAN). Get it at CDW for $32.
