This thread was not updated so I'm including the link to the latest (but still not new) drivers for Vista and WIndows 7, 32 and 64 bit versions.

I have the 4GB module and Windows ReadyBoost has never been enabled on my computer.
It is greyed out, with seemingly no way to rectify the situation.
The problem is, the module is not seen as a drive, for Windows to realise it can be used this way.
The ReadyDrive function seems to be working okay.
I must admit though, my computer was already quite immediate, with its 6MB L2 CPU cache and 4GB memory anyway, so it's hard to tell.
I did install the card AFTER I installed Windows 7.
I wonder if it would've made any difference?
They do mention on the Intel site, the fact that something is unavailable for a similar chipset to mine.
Why then would Dell offer the 1GB Turbo Memory as an option, if it was not fully compatible?
