4gbs of ram

[Mtotho]

i have 4 modules of 1gb corsair ram. I am aware that only 3.2gb of ram is detected in windows xp 32bit.. but in the bios only 3200mb shows up aswell. is this supposed to happen? i'd think that in the bios atleast they show all 4gb. thanks for the help.

Yes, nothing is wrong with your mobo/settings. Everything is good! :thup:

thanks, but all 4gb will detect in a 64 bit os correct?

yes

If BIOS sees ~3GB, then Windows will to. It doesn't matter if it's 32 or 64 bit.

If BIOS has a memory remapping feature, this can be used to move some of the RAM to another place i memory space, so it's addressable. And then the 64-bit OS can use it.

If the memory mapped IO and RAM overlaps, then the CPU cannot see the RAM, and no Windows version can magically change how the hardware works

ok if you have 4gb installed and your motherboard supports 4GB ( which i am sure it does) you should see all 4GB in bios. if you see 3.2 in bios with 4GB installed you have a problem.

If bios displays the usable amount of RAM, then all is okay (meaning that neither bios nor ram is defective)
