How can this be?

post #1 of 5
Thread Starter 
Hey all,

I have a little question regarding my old rig, with an Athlon XP 2200+ @ 1.84 (or something like that)Ghz ..or that it USED to be. As the months passed I noticed my clock speed AND cpu went down, from 2200+ as said, to first 1800+ @ 1.56Ghz, and then 1500+ @ 1.34Ghz.. where it is sitting now.

I don't have a clue how this could been caused, as it has never been gone for maintenance or something, so it's definately the SAME processor and I'm 100% sure it read as a 2200+ first..

Also, when I put a 512mb dimm in it, it was read as 256.. but when I replaced the CPU today with one I ..uhm... 'borrowed' from school, I suddenly had 512, as supposed to. When I found out it was actually slower than this one (it was only 998Mhz) I replaced it again with the 2200+, thinking that maybe Ã*t's speed would also increase again, but unfortunately it's still read as 1500+

Again, I'm 100% sure it was a 2200+ first, as this started happening WAAY before I had changed any part.

Any ideas? I've looked in the BIOS but I couldn't find any.

further specs are:
K7S5A mobo,
512 RAM
GF 4 MX 440 (the horror)
280 Watt PSU

I don't understand the "how" but I can confirm that this happens on one of my rigs, too.

It is an XP2400 and sometimes at POST it is shown as an XP1800.

turn off... turn on and lo it is an XP2400 again.

ho-hum

rofl, I'm so stupid!

There apparently IS some setting in the BIOS.. I found out just now after about 3 years
I forgot under wich tab you can change it, I'll post it right in a sec, but you can set the CPU and FSB clock from 100 to 133Mhz, for the CPU and FSB or so it seems. So if you both put them to 133mhz you get your normal speed, and if you set one of the 2, or both, to 100 you'll get a reduced speed.

Oh, and another thing, I still had the 256 RAM stick that was lying around here for quite a while now, so I plugged it in, but Windows (and task manager) still shows I have 512Mb, but CPU-Z says I have 786Mb.. Weird

Edit: the option was under CPU PnP Setup

You have just jogged my memory
it is that setting in the BIOS (for me) which sometimes changes itself somehow

Yea sorry it's memory frequency something, not FSB.. you can set them from 100 to 133, do it for both and you'll have the highest clock speeds.
