<font size="-1"><font face="Helvetica, Arial, sans-serif">There are
issues with running a 32-bit OS with more than 4GB of RAM.
You will need to enable PAE in order for the OS to see more than 4GB
and even then a 32-bit process can only allocate 2GB of RAM unless the
app has been written to take advantage of PAE. So, in my opinion, if
you have a 64-bit processor and more than 2GB of RAM, then without a
doubt, use the 64-bit version.<br>
<br>
I would do a fresh install if you are switching to 64-bit. I don't
think there is any issues with running 32-bit apps on a 64-bit OS since
I'm doing it right now. Just about all open source Linux apps have a
64-bit port. There are a few apps that they haven't made a 64-bit
version (Flash, Acrobat, etc), but I managed to get 32-bit Flash to
work in 64-bit Firefox.<br>
<br>
I would also make sure you can get 64-bit Linux driver support. Even
Windows doesn't have great 64-bit driver support.<br>

I did my googling and after poring over several pages of
forum posts, I still wasn't able to find an answer that satisfied me.<br>
<br>
I've got a server with an "AMD Athlon(tm) 64 Processor 3200+" running
Gentoo. Everything has been compiled as 32-bit (i686). I am in the
process of looking at a new server from Dell with a 64-bit Intel
Processor (currently comparing the Xeon <span id="ComparePanel">E5310
& the Xeon </span><span id="ComparePanel">5130). Questions are as
follows:<br>
</span>
<ol>
<li>If I plan on getting 8GB of RAM, will I need (or really want)
to
install 64-bit linux? Are there gains by going 64-bit or is it better
to enable high ram support in the kernel, compile as 32 and call it
done?<br>
</li>
<li>Will I be able to use the same binaries from the old server on
the new one if I install 64-bit? I'd really prefer to copy as much of
the data from the old server to the new one as I can. I am aware that a
64-bit chip can run 32-bit software, but I don't know the details. Do I
need a 64-bit kernel? How about libraries?<br>
</li>
</ol>
I realize these questions are probably very generalized, but I have
basically zero knowledge of the subject so I don't really even know
where to start. If people need more info to be able to answer, I'd be
happy to provide it.<br>
<br>
Essentially, it comes down to this:<br>
<br>
Should I use 8 GB of RAM in a 32-bit machine?<br>
How much work is it to transition a machine from 32-bit to 64?<br>
<br>
I really appreciate all the help TCLUG has been in the past. A good
group of solid techies. Thanks.<br>
