Some current or future Athlon users here might be like me and missed this piece of info:

The model number isn't the clock rate.
ie: The XP1800 doesn't run at 1.8Ghz clock rate.

So if your machine seems to be running
hot, double check your clock speed!
My XP1800 was toast after about 4 months at 1.8Ghz. Boy do I feel dumb.
(I've been at this PC stuff most my
life too) On the other hand, that
was a pretty good piece of silicon-
with some good cooling it could
have lasted a long time.

MODEL NUMBER CLOCK SPEED
1800+ 1.53 GHz
1700+ 1.47 GHz
1600+ 1.40 GHz
1500+ 1.33 GHz

Here's a site that discusses it:
http://www.hardware-unlimited.com/reviews/axp1800/
 
yeah, i heard they named the model numbers for the speed pentium they claim the chip is comparable. like an XP1700 running at 1.47GHz is supposed to be equal to a pentium at 1.8Ghz in "real world" applications.
 
AND from tom's hardware benchmarks its actually true that a Athlon 1800+ will equal or out perform a pentium 1.8
 
Maybe that came across as a slam
on the Athlon. Its not.

The only material
criticism I have is that there was nothing
obvious on the packaging to help
me avoid the misunderstanding.
Or in my motherboard manual for
that matter.

Actually I'm very happy with the
Athons, I have 3 machines with
them. They scream!

It was really just a warning to
help folks not fry theirs like me.
They are a great bargain considering
the performance.
 
my xp2000 clock is 1.67 but its faster and handles more than my sisters p4 2gig
 
...help me understand...

If you bought the 1800+ it should have been clocked at 1.533ghz or whatever. Why was it at 1.8ghz? The only way it should have gotten to 1.8 is if someone else performed plastic surgery on the processor and unlocked the multiplier or went into the bios and cranked the FSB up to some quite ridiculous number. Did you get it like that?

AMD processors have 128Kb cache memory as far as I know,
so at best they should equal the Celerons..

Actually I found that they perform exactly at how the actualy frequency set. A AMD 1400+, running at 1000MHz or so, is equal to a pentuim 1G as far as my experience shows.
 
???

we'd like to know where you found that. tom's hardware does pretty thorough testing and have found that the athlon (thermal issues aside) does more work per clock cycle..so the 1800+, while running at 1533 still performs as well or better than a p4 1.8ghz

Oh in my infinite wisdom I put it there
in the BIOS. I thought its default was
wrong. It was screaming!

my Athlon MP has 256
 
I have the 1700+ but I run it at 1.3 ghz to keep it cooler. I have a 3.5 slot fan cooling the hd and blowing across the memory, a Tornado on the processor. A 4.5" box fan on the power supply and an ac duct directed toward the open side of the case. ITs pretty smooth and quiet.
 
If it ain't broke, don't fix it

Wow I didn't know you could crank an 1800 up that far.


I prefer not to mess with my machine, I figure the dough I forked out was serious enough to let it speak for itself, for now. That doesn't mean ruling out speed increases in the future though.

As it stands I think the one recording I was doing was getting upwards of 60 tracks with no noticable defects. I don't actually own a small orchestra so I don't really need a computer to record one.



All I know is thing is a helluva lot faster and exponentially more stable than my last incarnation. However, when it comes to noise, I gotta say that even quiet fans are loud.

Yeah it was screaming alright..
"I'm melting! meeeeeltiiiiiing!"

Thats quite alright, we all make those mistakes and it makes for a good story to tell later on :) I still like to tell the story of how i wiped a hard drive by sending a little electricity through it (completely unintentionally). I'm too ashamed to explain any further...
