Use of Intel Turbo Memory for FL90 and deactivating it

Hi,

I just found out that TrueCrypt's drive encryption does not work with the Intel Turbo Memory of my Compal FL90 (at least when using Win7). Further more I am not sure if the Turbo Memory isn't a security risk for the encrypted system anyway...

Now I've got three questions:

1) IS the Turbo Memory a security risk? Maybe also see http://forums.truecrypt.org/viewtopic.php?t=9859

2) I've got 4GB of RAM. Can Turbo Memory still improve my performance or is it useless in this case? My own "booting-time-measures" led to quite weird results:
~48sec first run with ReadyBoost&ReadyDrive (booting 3 times)
~1:11 first run without ReadyBoost&ReadyDrive (booting 3 times)
~1:13 second run with ReadyBoost&ReadyDrive (booting 2 times)
~1:10 third run with ReadyBoost&ReadyDrive (booting 2 times, but WiFi-switch manually deactivated)

3) How can I deactivate the Turbo Memory chip? I could not find any option in BIOS (V1.17).

Thank you in advance!

 

I wouldn't say it's a security risk, but whether or not it'll be useful to you really depends on the size of the chip you have.

First: to deactivate it, you need to uninstall the Turbo memory driver, shut down, and pull out the Turbo memory MiniPCI-E card that's in your system.

Second: If you only have a 1GB module, it's pretty much useless. I have a 4GB module in my laptop and I enabled the User Pinning feature so I can keep parts of programs installed on it. For that it seems to accelerate program loading. Other than that, unless you're running with 1GB or less of RAM, you're not going to get much of a boost from it. Just pull it out of your system.

 

Thanks a lot for your quick reply!

You saying that it doesn't improve my performance makes it easier for me to deactivate it without a bad feeling

I just found out (and was very surprised) that it is sufficient to deactivate the ReadyDrive function in the Turbo Memory Console, so I don't even have to pull out the card. TrueCrypt doesn't prompt the error message anymore after I did so.

 

Well are you running x64 windows?

 

I have a 2GB module. It is useful, but not sure if it was worth it.

 

Sure, otherwise 4GB of RAM wouldn't make much sense Or are you asking for another reason?

Are you using the User Pinning feature like DigiDoc?

@DigiDoc:
How does this work in practise? Is there an Intel program in which you can simply check a box for an installed program (e.g. Internet Explorer or Firefox)?
And: Does this feature depend on the module-type (maybe the size) or only on the software?
