you can, but if your arch is x86 not x86_64 you can use only 3,76 gb of ram memory
if you want more - you should choose 64-bit arch instead of 32-bit

1)use "cpu-z" utility (in windows or find something for linux) there is difference between processors, socket 478
2)new motherboard + new processor
3)x86 max supports 3 gb of ram

for present time there is no need to upgrade to x86_64, there isn't any difference, because of:
1)not very much software written for 64-bit arch
2)if tou use 32-bit software your 64-bit OS will be working as 32-bit

Can you help with this problem?
