Fastest cpu for Asus A7N8X Deluxe m/b?

Hi, can anyone please tell me what is the fastest cpu that I can fit to
my motherboard?

The M/B is an Asus A7N8X Deluxe, rev 2.0 using bios version 1008.

Its a Socket "A" M/B and I think the fastest cpu for it may either be a
Athlon XP 3200+ or a Sempron 3200+ but I'm not sure which?

Can anyone tell me the main difference between these two.

Athlon XP Barton 3200 is the fastest stock speed CPU.  It
has 512MB L2 cache to differentiate it from the non-barton,
which has 256K.  These are the contemporary CPUs for the
board, I am unfamiliar with what AMD has done with Semprons
for socket A, I vaguely recalled they were increasing the L2
cache on those, but it may depend on which revision of
Sempron you bought.

If you really want max performance out of that board then
get a Mobile Barton, XP2400 to XP2600 and overclock it.
They'll typically o'c to 2.3-2.4GHz without special measures
(you just need a fairly good heatsink), some even higher.

Depending on how much you'd have to spend on this CPU it
might be as cost-effective in the longer term to replace the
motherboard now to support newer CPU architectures.
Whatever present CPU you have (which you didn't mention),
might not have a multiplier lock and could run at the
fastest FSB & memory speed your board supports,
DDR400/200MHz, which could make an upgrade to the fastest
CPU the board supports, not as much of an upgrade as you
were hoping for.

If you have a lot of DDR(1) memory to reuse, one alternative
would be a socket 754 or 939 motherboard and Athlon 64.  If
you had any ideas of getting more memory any month soon I'd
suggest you instead move to DDR2 memory based platform now.

    Here's a cpu like kony is telling you about--watch out for line wrap on
link. Mine happy on your mobo for 3 years @ 2.41g.  sdlomi2

The particular specimen you linked may not be a very good
overclocker, the listing notes it overclocked (merely) past
2.3GHz with liquid cooling.  An average Mobile Barton with
an average liquid cooling ought to be able to hit 2.5GHz.
On the other hand, if the CPU can be won cheap at auction,
the couple hundred MHz difference in speed might not have
been worth any extra $$ spent, except that we also don't
know what voltage that specimen needed to go past 2.3GHz, if
it was an unusually poor overclocker that needed in excess
of 1.85V just to attain > 2.3GHz, it wouldn't be very easy
to run it at that speed long term on air cooling.

The above is only speculation, it might o'c just as well as
any other, I just find it odd someone would invest in liquid
cooling and choose to o'c, then only o'c that chip to that

    You're so right!  Did you notice also that he was not using the A7N8X
Deluxe?  I've bought a few cpu's, not many, that ran better for me than for
the advertiser.  This specific seller either had a "bad" cpu (as you
guessed) or else did not know much about o-clocking.  Should've known liq.
cooling was NOT necessary w/this processor when used with proper mobo and
ram.  I've seen so many unbalanced systems--some very nice components mixed
with el cheapos--that resulted in average or below performance.  In essence,
I'd put my $ on expecting to get like or better performance than he, using
the A7N8X Dlx.  (I've lost bets before;) )   s

I don't recall the exact count but I have a few mobile
bartons here, maybe 3 or 4.  They all do 2.2GHz on every
motherboard I've tried, though one I recall (A7V333, an
earlier revision) wouldn't get much over 2.2GHz.  Everything
else, even some mATX boards would get them over 2.4GHz
easily but some of the boards (particularly the budgetized
and smallish) mATX had worse capacitors and I wouldn't
expect them to be able to run a higher overclock long term.

So it was with the A7N8X series too, I have a Deluxe version
with pretty good Rubhcom MBZ capacitors on it that
overclocks well but some (think it was the -X version) had
lesser spec'd Nichicon or United Chem-Con caps... not that
these two are bad brands but these two companies also had
more equivalent ultra-low ESR products availale which
weren't used so it seems the -X had cut a few corners there
to reach a lower price-point.  At least they didn't use some
of the poor generic caps that were so prone to failure but
get a cap hot enough and it'll go just the same, if it just
wasn't suitable for the amount of current-> ripple
introduced from high o'c.

The Athlon XP 3200 is the fastest of those two and I think pretty much the
fastest CPU for those type of boards.

Just don't spend $160 dollars on it. You can get an Asrock motherboard and a
socket 939 cpu on new egg pretty cheap these days. And best of all, you can
transfer your ram vid card and hard drives to work on it too
has agp and pci express slot for graphics. I built a computer using this
board and its stable with good overclocking features.

Manufactures site says its dual core ready but you may have to flash the
bios first.
