PAE VS SQL Server AWE

Hi,
I have set the boot.ini /PAE and 3GB Parameters in my windows 2003 server
enterprise.
And SQL Server 2000 also open AWE's "Max Server Memory" as 6G (I have 8G
physical memory).
So, these 2 options -- boot.ini 3GB parameter and the "Max Server Memroy" of
SQL Server 2000 as 6G can use at the same time?
If can't, what's problem will happen?
Thanks!
AngiThis should be fine.
Problems can occur if you use /3GB when you have over 12GB of Memory,
although some people say you can go up to 16GB. You'd have to test it on
your system. But 6GB should be fine.

table Windows uses to manage the physical memory...such that it can
manage a maximum of only 16GB of physical memory." Is that right or is
12GB the magic figure?

Officially, from MS, 16GB is the number, but some hardware vendors (they
might produce ES 7000's) have recommended to customers to use a maximum of
12GB.
