View Full Version : Hardware: AMD won't run at advertised speed
01-16-2003, 08:14 PM
I've always used Pentiums in the past and have never played with the clock speed in my BIOS before, so this AMD stuff and "setting the clock" deal is a new animal for me. If anyone has links to info on this, I would be very grateful. I am not looking to overclock it or anything like that, but I would like to see it run at the speed that I feel I paid for.
It's a 2200+ AMD Athlon XP on an MSI KT4V mainboard. I've got 512 Mb of 333 MHz DDR SDRAM, 400W power supply, and a GeForce 4 Ti4200 card.
So far, I've changed the mainboard clock from 100 (default) to 133 and the processor jumped from 1350 to 1800 MHz. The mainboard is capable of a setting of 280, but even at 166, which would bring the processor up to 2200, is too much and the system won't boot.
Am I supposed to increase the CPU's voltage in the BIOS settings to get it to go faster now? I am uncomfortable with anything that will cause the processor to run hotter, so I am asking for advice first on this. Right now it's running at about 47C and I am hesitant to try to run it any hotter than 55C.
I've checked the AMD and MSI sites as well as searched online for tech pages, but haven't found anything that discusses this directly. Most of the overclocking sites talk about soldering and more aggressive solutions, whereas I am only interested in getting this to run at the advertised 2200.
Any links or advice would be very much appreciated.
Thanks all. :wip:

erm , 2200+ is a rating, that not's the real ipc(instructions per clock cycle)
you are doing nothing wrong, i have amd too, xp 1800+, and that's running at a true 1533mhz...
Amd simple re-introduced this rating again, cuz their cpu's can do more in one clock cycle than an intel can do

from my understanding, a 2200+ runs at 1800, my 2000 runs at 1670. Not sure why this is, but most places that sell them specify that. If you buy them from newegg.com they list them by their actual speed. Hopefully some one can shed some light as too why this is.
shoot, solesurvivor, you beat me too it. I type too slow

Awesome guys! Thanks for the replies.
I am so glad I don't need to mess with tweaking this thing any more.
Thanks very much for the answers.
After looking at the box again, I am seeing "operates at 1800 MHZ" in the tiniest of type in one corner of the label, while 2200+ is huge and in your face.
I thought that 1800 was the recommended speed whereas 2200+ was the "but you can really get it to do this - wink wink nudge nudge" speed.
Thanks again. I am finally off to do some animating now.
*sigh of relief*

It might depend on the motherboard you got. The bios in my new Abit motherboard lists the 'rated speed' and not the actual speed unless you manually set the cpu speed. It actually says 2000+ but by looking at the system bus speed and the multiplier I can confirm the 'true' speed is a mere 1.67 megahurtz.

MP 2400, running at 2.266Ghz :) now if only I could install some sort of "operating system" so I could actually USE it....;):D

This MoBo came with a bunch of different software and at least 2 give actual CPU speed. WinXP Pro also gives the processor speed. All agree within 50 MHz of each other.
It's faster than the dual 600 Pentium 3 I had, so I'm still happy. (But that's chained to the renderfarm now and still whizzing away. heheheheh)
Take care, guys

Are you an EB?

as EB as you can get.
First rule of EB, you don't talk about EB....
