I was wondering if anyone would know the cons of running a PAE kernel...? I have a 4GB pc and was wondering if it was worth going the PAE way to gain those exta 700MB...
You should use 64 bit if possible but if you're seeing 3.2GB, it's more likely that your motherboard is not capable (I have one of those here right now).
In the past, I heard that these 700MB were normally reserved for bios or chipset stuff...
It still is, even with with 64 bit. If your motherboard supports remapping this memory with 64 bit you can use the whole 4GB. Otherwise you're limited to 3.2:
Second this. It doesn't matter if you use PAE or x86-64. Without support in the bios for remapping the lost memory you'll never recover that extra RAM.
