Re: st: optimal configuration for windows 32/64
I just wanted to add a little something to Dave's email below
You can always try XP PRO 64bit for free. Microsoft allows a trial
period of 180 days I think. It is easy to install on a separate disk
partition and see if it grows on you
That's what I did because I was having problems with XP PRO 32 issues
with contiguous memory (which do not exist now with Vista)
Dave is right in that not all drivers are instantly available but
with some fiddling on line you can usually find what you need
Most software (but not all) would still run in compatibility mode
even if they are not specifically designed for 64bit machines
However, to gain the full benefits you will need a 64 version of
Stata. You can buy an extra licence for the 64bit version which to
install in the partition where you run the XP PRO 64 bit
Also, I totally agree with Dave's advice on the machine to go for
(especially on graphics cards). I just wanted to add that, looking at
Stata's website, the advantages of having a MP machine largely depend
on what you do with your data. For instance, it looks like the gains
in speed are very limited even with a quad core if you run an
xtabond, twostep (http://www.stata.com/statamp/report.pdf). I would
be interested to know what other users think of this aspect
Hope this helps
Bob
As you probably already know 64 bit Windows machines can access far
more memory that their 32 bit counterparts.
And since Stata places data in memory, this is an important
advantage if you wish to analyze huge data sets. But there
currently are disadvantages. If my understanding is correct, many
standard programs now won't work in a 64 bit machine, although this
situation probably will gradually improve. It follows that if you
plan to use the machine in question only with a few specialty
programs like Stata, and you wish to analyze extremely large data
sets, than a 64 bit machine probably is a good idea, but you should
buy a lot of memory to benefit of the one major advantage offered by
this choice.
As far as speed is concerned, I know of two options. Particularly
if you are buying thru an academic or a governmental account (but
I'm not sure about Dell discounts for non US governments), you can
get a good price on a workstation from Dell. I have a four core
processor Dell machine that seems to be faster than the standard
consumer boxes with a strong chip and I only had to spend a bit more
than what you plan to spend.
Another option is to get a middle range box designed for computer
gamers. These machines are fast, but I wouldn't let them sell you a
computer with fancy paint or other unnecessary items. Also if you
only want to use such a machine for data analysis, be sure to
economize on the graphics card. Gamer machines come with expensive
cards that you won't need for data analysis.
I'd be interested in other thoughts on this issue by people on this list.

Dear all
I have been searching the statalist archives looking for advice on
optimal configuration to run stata in a windows 32 bit and in a
windows 64 bit environments, but I did not got a clear answer to my queries.
I need to work with census data uploading into memory about 2
gigabites of data. My questions are the following
1. should I go for windows 64 instead of windows 32?
2. If I go for a Microsoft 64 OS, would I notice a performance
improvement if i switch from a stata 32bit to stata 64bit?
2. Any advice about the best processor around? I have around US$
4000 to spend in a computer that can allow me to work at reasonable
speeds with a census database.
I appreciate your help
Julio
