AMD Athlon XP2500+ vs AMD Athlon XP3000+

Hi all;

Sorry if this has been talked about before, but...

AMD Athlon XP2500+ vs AMD Athlon XP3000+

Apart from price, what advantages would going with the 2500+ be
against the 3000+.

The other parts are;

CASE-V1000C - THERMALTAKE Xaser III Steel Case Blue
Antec TruePower TrueControl 550W ATX PSU
ABIT NF7-S v2.0
Gigacube ATI 9800 128MB DDR

I am looking to run at least 2.6ghz, without too much trouble.

How much difference would there be between the 3000+ 333fsb and the
3000+ 400fsb?

If I get a cpu with 333fsb, any use in getting memory faster than
pc3200 cs2? Will be looking to get at least 1 x 512Mb stick.

 

None, they're the same core.

Good luck.

2.3GHz, without trouble
2.4GHz, distinctly possible.
2.5GHz, pushing your luck, even with very good cooling and lots of voltage.
2.6GHz, extreme cooling and lots of voltage and lots of luck. You'll almost
ceertainly probably need >2.0V

None, same core. Default clock speed on the 400fsb slightly less.

Only if you plan to run the FSB >200MHz.

I got a question ben
will his 2500+ oc to 3200+ use the same amount of power (or more to the
point product the same amount of heat) as the 3200+

 

Given the same voltage, I don't see why there would be any more power
consumption of a 2500+ than with a 3200+.

I'll reword it: A Barton core at 11*200MHz being driven at 1.65V should
consume the same amount of power as a Barton core at 11*200MHz being driven
at 1.65V.

I do not understand... they run at different speeds...

Ok I could live with 2.4 possible, is this on the 2500+/3000+ or
both???

I would have thought you could oc the 3000+ more than the 2500+!

Ok! any ideas on which would be best. Pc3500/pc3700 and at what
latencies cs2...?

Thanks for your reply...

 

Since they are the same core, both.

That motherboard has been known to go as far as 230MHz (ish, some poeple
will claim more), so PC3700 will give you known timings at those pseeds.

However, my Corsair 3200LL does 220MHz 5-2-2-2, which is good enough for me.

You'll want CAS2, the other timings aren't nearly as important.

The default speeds of the cpu's are defined by the bridges on the outside
of the core. Since the FSB and multiplier is not locked, you can set the
speed to whatever you want as long as the cpu will run that fast. The
2500+ default is 11x166. The 3000+ has 2 models. One has a default of
13x166, and the other is 10.5x200 I think. The 3200+ is 11x200. Since you
can change the default multiplier and FSB, the model number doesn't really
mean much. IUOW's, you can clock a 2500+ the same as a 3200+, or you could
even clock it down to something much lower than a 2500+. Same for the
3200+.

Depends on how lucky you get, as far as the cpu goes. You might get a
2500+ that will clock at 2500MHz and you might get a 3000+ that won't even
clock at 2400MHz or the other way around.

They're the same cpu. Only the defaults are different.

This will work well.

Hi All;

Thanks to all the replies. Here is what I will be after;

CASE-V1000C - THERMALTAKE Xaser III Steel Case Blue
Antec TruePower TrueControl 550W ATX PSU
ABIT NF7-S v2.0
Gigacube ATI 9800 128MB DDR
Corsair 1024MB TWINX-3700 DDR (will this run at cs2???)
AMD Athlon XP2500+

What do you think?

Seems pretty good, but I'm not sure the PC3700 will run at those speeds. If
a 200MHz frontside bus is your goal, then PC3200LL will do you fine from
Corsair, and is probably a bit cheaper too. Have a look at Corsair's
website http://www.corsairmicro.com/corsair/xms.html to see what I mean
about the memory timings - they have PC3700 running at CAS3

 

I have seen some forums say they can do cs2 timings... But not many...

I am a bit hesident, but what the hell.... lol

 

From anecdotal evidence you are likely to have a better chance of running
CAS2 at 220MHz with 3200LL, then the 3700.
