I just instaleld a fresh copy of Windows XP Professional x64, and from what I gather, this version can support up to 128 GB of ram? My system is currently only showing 16 GB out of 24 GB? Any ideas to why this might be?

Check your motherboard specs. That may be the most that the motherboard can support.

Check boot.ini to see if it has the /3GB switch. If so try removing it.

My motherboard supports 24 GB. Had Windows 7 installed and saw all 24 GB no problem. The issues is not my hardware, it is the OS.

I will give that a try ijack, thanks.


That was it ijack, thanks again :)

Ewww... why would you go backwards that way? XP-64 is Microsoft's red-headed stepchild... it gets no respect. Support for it is limited compared to Vista and 7.

It was for testing, seeing if I got better results,
