RAM and Virtualization questions

Recommended Posts

1. I have 2 DDR3 RAM slots in this laptop. It currently has two 2GB sticks (OEM). If I wanted to upgrade [preferably to 8GB] for reasonably cheaply, what's a good brand to go with? Reasonably cheaply being <$100 USD if possible, I'm not really sure of the going price on RAM at the moment.

 

2. Running Speccy gives me information about Virtualization in the CPU page:

Virtualization Supported, Disabled

 

I have an AMD A6-3420M cpu and was wondering if there is any benefit to enabling that and what it does exactly. I read the Wikipedia page but it was not particularly useful to me.

Go with any name brand for RAM, Corsair, Kingston, Crucial etc., you can use http://www.crucial.com to pretty easily find guaranteed compatible RAM for your laptop.

 

You don't need virtualisation enabled unless you are running virtual machines, since you don't know if you need it or not, you don't. ;)

What if I was going to run a virtual machine? I technically do have one on here, VBox with Windows XP in it. I installed it to play games on but the graphics card support was lacking so I kind of gave up on it.

 

I guess I still want to know what it does... :P I mean if it's just what Wikipedia says then does the CPU automagically figure out that I'm running a virtual machine? Does VirtualBox tell it that?

It basically allows the virtual machine to use the raw power of your CPU with (almost) no difference to you using it in a non-virtualised environment. With it disabled, the virtualisation environment is likely providing a software interface which sits between the virtual machine and your real CPU, and translates everything, which is slower.
