WinXP and Memory

[XtaszY]

 I have just installed 1.5 GB of DDRam on my PC and I noticed that my winXP doesn't work properly anymore. I heard that windows XP has difficulties managing over 1GB of RAM. Does anyone know if this is true? Can anyone tell me why (if yes)?

Not true.  Did you install new memory along with your old?  If so, are they different brands?  Do you know the maximum amount of memory your motherboard will accomodate?  What is the make and model of your computer? What brand memory did you buy, and what specific memory?

You say your computer does not "work properly".  Exactly, what do you mean?  Does it completely bootup?

Most likely you either have it installed wrong or you bought the wrong RAM for that machine. Go to www.crucial.com and see what you should have gotten and compare ALL the details (not just speed) to what you got.

You may want to remove and reseat the RAM, and even run memtest on it (free download at www.memtest86.com). Check each stick at a time, then all together for at least an hour.

Again the specifics on your problem would be illuminating.

My PC works generally fine, my CPU is an Athlon 64 on 3000Mhz, mainboard MSI K8N Neo4 with two GEIL memory sticks one of 1GB and another one of 512MB with identical parameters. What bothers me is the fact that he keeps bulding virtual memory of over 700MB even if it has over 1GB of free memory. I've checked in Control Panel to make sure that the virtual memory is set to automatic. On top of that, I haven't noticed any change in the speed that applications are ran (games, software, webpages...), they even run slower and I don't think that is a normal thing to happen.
I have posted this question here because I heard that WinXP has difficulties in managing amounts of memory exceeding 1GB. Even the salesman where I've bought the 1GB stick told me this.
That's about all  :-/

" I haven't noticed any change in the speed that applications are ran (games, software, webpages...), they even run slower ..."  Well, which is it, no change or slower?  If, indeed, slower, then there's clearly something not right, but I'm not sure what it is.  Did you follow GX1_MAN's advice?

As far as virtual memory is concerned, I believe it's normal for Windows, if you let it manage virtual memory, to allocate more space when you increase RAM.  

"I have posted this question here because I heard that WinXP has difficulties in managing amounts of memory exceeding 1GB. Even the salesman where I've bought the 1GB stick told me this."  Well, then <LOL>, why did you go ahead and buy an additional 1GB?  

I believe Win XP is supposed to be able to handle up to 4GB on most systems.  If you do some Googling, I think you'll find numerous references stating that.

Not yet, I don't have much time for that now, but I'll do it

"Well, then <LOL>, why did you go ahead and buy an additional 1GB? "

Because I could  

ok
I think I'll install win vista64

Thanks to all for help

"Because I could", always a very good reason.  What could be more logical?

[GX1_Man]

Easy there, Soybean. THat is the number 1 reason people will upgrade to Vista anyway. Not increased function, but "because I could". MS is banking on it.

[XtaszY]

sorry!
I try to be funny
sorry again
I buy the memory because, is right, i want to improve my computer

Thank's again to all
