What's my maximum ram capacity?

  cheerup347 00:13 19 Sep 2009


I have a Pentium D quad core PC running windows 7 and I currently have 2gb Ram installed in my comouter. I have 4 slots and wish to upgrade.

How can I find out what my maximum ram capacity is?

also even if the motherboards maximum capacity is (for example) 8gb... will my operating system have anything to do with it?

Just let the scanner run it will tell you what you can get and how much it will cost.

As buteman but also read the info that came with your PC on the motherboard. If you had a manual that is. Crucial's scanner is not fool proof but pretty good. Use the motherboard name to get compatible ram modules rather than the auto scan they offer.

"will my operating system have anything to do with it?"

Yes -

32-bit Windows operating systems basically have a 4GB address space. Since some is taken up by various hardware bits in the system, max RAM will be 3-3.5GB roughly speaking (even if you fit more).

64bit Windows OSs don't have that limitation.

no, but it will have something to do with how much RAM will be recognised. Guideline figures are max 3.5GB RAM recognised with 32 bit operating ssytem. Technical limit for 64 bit is higher than most people's budgets allow to max out.
