Specs: Windows 7 Home Premium 64-bit, i7-860/4 GB
Hello everyone,
I'm interested in installing 12 GB of RAM into my Dell Studio XPS, it's got 8 GB at the moment. The system has four DIMM slots and I'm wondering if it's okay to install three 4 GB sticks to make up the 12 gigs of RAM? I've been reading that RAM sticks should be installed in pairs for best performance but I've also read for certain motherboards that may not necessarily be the case, is that correct? Someone suggested I install two 4 GB sticks and two 2 GB sticks to get my 12 GB and I'd also get the best performance, does that sound right? Also, what's the fastest RAM speed that can be installed in this PC? Thanks in advance for any info you can provide!

Yes you need to install in matched pairs in order to take advantage of the dual memory controllers. Use 2-2GB sticks or 2-4GB sticks. Pairs must be closely matched to work correctly. You also need to consult your MBoard manual to learn how much and what type of RAM you can use.

What do you primarily use your system for? I wouldn't expect to see a huge performance difference between 8GB vs 12GB unless you run programs that are very memory intensive.

Thanks All for your replies,
Just to be sure, it's okay to go ahead and install the two 4 GB sticks and two 2 GB sticks as long as they have the same specs? OThehill, any idea where I can get the name of the motherboard manufacturer other than opening up the PC and looking inside? I couldn't find it anywhere on Dell.com. Mickliq, I use Dragon NaturallySpeaking 11 dictation software A LOT, pretty much all the time. I'm disabled and so use DNS rather than my mouse and keyboard.

I noticed the "physical memory" indicator in Task Manager is listed at 28% when I have DNS running as well as Windows live Mail, Mozilla Firefox as well as the 56 other processes listed as running under task manager. That doesn't seem like a large amount of RAM in use but I know they'll be times when I'm running more apps.

Thanks again!

You can use SIW standalone. It is free and will give you the information you need.
