If you are talking about Vista 32-bit, yes. However, on some
systems, after upgrading to Vista SP1, they say that up to 4GB of
RAM is being detected and being utilitzed.
Please note that 64-bit systems don't have a 4GB RAM limitation.
If you encounter it, throw your motherboard away and ask for a
refund from the shop.
PAE, or Physical Address Extension, is a method used to overcome
the 4GB limitation in 32-bit systems (if supported) .
