Built in ram limit for 64 bit
Hey all,

I have been thinking about getting a new computer, and the motherboard I am looking at is capable of holding up to 8 Gb of ram. Now it appears as though for 32 bit linux, in order to use more than 4 Gb of ram, you had to enable a certain option in the kernel, but if I remember correctly, there was also a performance hit for doing so. Of course I will be going 64 bit, and so I am wondering if there will be any problems with > 4 Gb of ram? Or will Linux take care of everything in 64 bit mode?
