Solve : Questions about Memory?

Answer»

Hi,

I'm using Windows XP. I installed 3 GB of ram in dual channel mode (2x512 + 2x1GB), but windows only recognizes 2.5 GB of it. I researched some and came to the conclusion that the max memory it can handle is 4GB, and other devices take some of the remaining address to handle their memory etc. (I have a 512 MB Graphics Card)

-Can this be fixed so all 3GB is used by Windows? If not, is my memory still operating in Dual Channel mode? CPU-Z correctly recognizes both memory and says it's in Dual Channel mode.

The second question is about Virtual Memory.

1. Do I really need it? In class I learned that if you do have virtual memory, the computer ships all the useless info in memory to it, and focusses on the main program/task at hand, such as a game.

2. At the same time, I realize that it can take a LONG time to access the virtual memory, and I do notice skips when I'm gaming a lot.

3. Currently virtual memory is at 2GB on all drives. If I take the virtual memory out, while it improve gaming PERFORMANCE? Since the processor doesn't need to stall to handle virtual memory?

Thanks & God Bless

Could you explain in a little more detail? If I removed one of the 512 sticks, it wouldn't be in dual channel mode any longer. Will the 2x1GB still be in dual channel mode?

Thanks for the heads up on virtual memory - would more virtual memory improve performance?bump!

Also, is there an EASY way to upgrade to XP 64 BIT? My processor can handle it. That way I'm ASSUMING I can use more RAM - I'd like to use 4GB of DDR ram, as it is cheap right now.

Is it better to set the ram to 200MHz?

Thanks & God BlessOverclocked RAM can become unstable....

What is it you want to accomplish here ? ?Quote from: patio on August 18, 2008, 09:00:54 PM

None of it is overclocked. The RAM COMES at 200MHz, but I currently set it at 166MHz - the question is whether 200MHz is better - cpu-z stats say otherwise.

The main question is - is there an easy way to upgrade to XP 64 bit? My processor is a 64bit processor. That way I'm assuming I can use more RAM - I'd like to use 4GB of DDR ram, as it is cheap right now.

Right now windows only detects 2.5 GB, as can be seen in the screenshot ;p

Thanks for the help.
