WinXP Maximum ram

[UnseenMenace]

I was of the opinion that WinXP pro could use 4 gb og RAM however I have a system which has 2gb of ram and yet only see's 1.5 gb. there are two sticks of 512mb and one stick of 1 gb

Anyone know what the situation is, what the problem may be ?..... anyone else running this amount of memory or more without problems ?

UnseenMenace, I wonder if it might be a limitation on your motherboard? I've heard that XP has a 3 or 4 gig limit myself so I wonder if that is that case.

what board do you got unseen ?

i too, think its your mobo... is it possible that it is trying to run the 1024 as 512 for some reason?

Windows XP Home: 4 Gigabytes
Windows XP Professional: 4 Gigabytes

Durring post do you get a memory count ?

The main board my be the Limiting factor. Or you might want to install each ram moduel alone and be sure windows is seeing it for what it is.

I think some the NF2 platform is limited to 1.5GB ram.

Maybe one of your 512 sticks is corrupted.

I know the the 845 chipsets have a limitation on the type of ram that is put in the MB. Even though you have 3 ram slots, you can only use 2 dual bank dimms. slot one uses its own 2nd bank, but slots 2 and 3 SHARE thier 2nd bank....

Check that stats on your MB

i agree, it may be the m/b

test your 1Gb Ram chip, and see if you have 1 Gb Ram, your mobo might not see it as a Gb, but as a 512Mb, since that could be the maximum size it allows, I had a problem like this on a P2 233, I dropped 2 256Mb chips in it but it read as 256Mb ram each slot could only handle 128Mb ram,
