Sempron 64 2500+ really 64-bit ?

This thing is driving me nuts. I've heard a lot about entry-level
(low PR) S754 Semprons that were recently introduced into the market,
labeled "Sempron 64". I know about 32-bit Socket A and Socket 754
Semprons, but these newer CPUs starting from 2500+ are touted as
64-bit.

Finding authoritative confirmation that they are indeed full 64-bit
CPUs is more difficult than I thought. It's impracticable to
investigate all the links turned up by Google by searching for
"Sempron 64".

I have not been able to find any information at the AMD site about
64-bit Semprons. The first time I searched for "Sempron 64", it
returned "Search forbidden" in giant black letters.

There's no doubt that AMD now makes 64-bit Semprons in S754 and
Tom's Hardware lists them (including the 2500+ whose specs are given
as 90nm, SSE3, etc.), but then goes on to say :
"Sempron 64 users (3400+ only) can install Windows XP x64 edition".
http://www.tomshardware.com/cpu/2005...empron-02.html

The part that confuses me here is the qualifying "3400+ ONLY"
statement, and the lack of info at AMD.

I posted a similar message at alt.comp.hardware which received 0
replies. As I said, it's driving me nuts. Can anyone clarify ?

AFAIK, all Socket 754 Sempron being produced now are 64 bit enabled. The
first one out was the 3400+, and was the only 64 bit Sempron for a short
period. You'll need to be careful when buying Semprons for some time to
make sure you get a 64 bit version if that's what you want.

Quoting http://www.extremetech.com/article2/...841934,00.asp:

"64-bit support: Some Semprons got it, some don't. The Sempron 3400+,
reviewed here, does indeed feature 64-bit support. Lesser models,
including all the Socket A versions, only support 32-bit OSes. "

Hope this helps.

That's the same article I referred to in my first post. I read through
most of the pages, but unless I missed something, it does not make
clear if the lower Semprons are 64-bit. In fact, it seems to indicate
on page 02 that only the 3400+ is 64-bit.

Ignore the Tom's Hardware info. The 3400+ was the first 64-bit Sempron
that was introduced, and it remained the only one for a long time, but
now we've moved on, and AMD has introduced lower priced ones now.

There is no other info available at www.amd.com - at least, I didn't
find it - especially with respect to steppings (E3, E6) of these Semprons.
