Overclocking AMD Athlon XP 2000

hydr0:
You say you cant get yours to run XP2300+ (which i would assume to be ~1.9Ghz) -- what mobo you runnin?

Well I must say I am incredibly worried for your computer -- my Pentium3-800 doesnt run that cool (okay maybe it does but i have some tricked out cooling on it -- the stock variants dont reach those lows)

If you are running the ASROCK mobo from page 1 of this thread then if ASROCK is a subcompany of ASUS you might have a chance at the OC (does anyone know if ASROCK is a subcompany for ASUS?) and if so, you might want to use the ASUS Monitor tool to measure the temp of your stuff again. Unless you live in Syberia or Antarctica or something like that, your mobo temp should be in the 30°C range even if you only have onboard video which generates less heat.

1. Well firstly, if you are running the same mobo as per page1 of this thread, that mobo has a 266FSB and you've effectively clocked it to 333FSB which is quite the heat banger.
2. What HSF do you have running?
3. For the record do you have a ThoroughbreadA or Palomino? There's a big difference in the heat output of those two families however the drop doesnt take one down to the 30°C arena. Since you said that you have a 266Mhz-based mobo, i will assume you are running the Palomino (which is a heat cannon)

To save everyone some work in looking stuff up, here's the low-down on the two variants of the XP2000+
Palomino XP2000+
Actual Speed: 1.67Ghz
FSB: 266Mhz
Multiplier: 12.5
Core Voltage: 1.75
Max Power Consumption: 70W
Process: 0.18micron
Max Voltage: 1.85
Maximum OC Potential 1.8Ghz (XP2200) << note that this is with some fancy ass cooling

Thoroughbread A XP2000+
Actual Speed: 1.67Ghz
FSB: 266Mhz
Multiplier: 12.5
Core Voltage: 1.60-1.65 depending
Max Power Consumption: 60W
Process: 0.13micron
Max Voltage: 1.80
Maximum OC Potential: 1.86Ghz (XP2200) << note that this is with some fancy ass cooling

Now unless you have your numbers mixed up or your software is messed up then I would hazard a guess that your actual thermal diode is cracked out -- touch the heatsink for a bit -- if you cant touch it comfortably for more than a short while then it is NOT running 30-35° -- you can hold on to a 30-35°C heatsink for damn near forever.

When I had my Palomino XP2100+ (its at home now so i cant verify) with a Volcano7+ HSF in the middle of winter -- with my window open 24-7 (hey -- im crazy) I kept a temp of 34-38° under mild duress. Come springtime i lived in the 40-44°C range. Middle of summer I was hitting 55°C on a daily basis with little or no stress (and thats with 10+ fans in the case) -- so check to see if the diode is reporting the proper temp cuz I dont think it is

Im not suggesting you are not reading the values correctly -- im suggesting that either the program itself is reporting incorrect values or thermal diode is messed up. -- i would know, my thermal diode is messed up and when i goto bios it keeps messing up between CPU and MOBO temps -- and has a 30°C fluctuation.

You havnt answered my question though: what heatsink-fan are you running on that? Cuz unless you got some form of peltier or water-rig in there, XP2000s dont run at those temperatures let along OCd Palominos (which you also didnt answer my question regarding).

 

In that case i can absolutely beyond a shadow of a doubt tell you that either the software is messed up or the thermal diode is on crack.

The stock AMD XP fans dont give temps in the range of 30-34°C -- even if you underclock the chips. You need fancy cooling to get that kinda temp -- not to mention that temperature under duress. Are you sure you dont have the CPU temp mixed up with the mobo temp? 30-34° is normal for mobo but certainly not for a stock-cooled Palomino chip.

Hydro said it best:

EDIT: I just realized you said ur CPU runs 20-25 normal and 45 as a max (as opposed to 30-35 which i somehow interpreted) ... i can definitely tell you something is quite wrong. Even Pentium3 500s using 2 fans (the Slot P3s) werent that cool. Hell my Coppermine-800 boots up at 30ºC

1. Not neccesarily (and hence the reason bridge fans are omitted on ASUS boards) -- often you will find that if there is a fan there, dust has a tendency to settle and harden which makes that heatsink essentially a heat insulator.
2. Note that the bridge heatsinks are typically aluminum (and specifically not copper) because aluminum has the ability to take heat away from the source and slowly bleed it into the ambient environment and still be effective as it absorbs heat (cooper heatsinks on the otherhand, without lots of airflow become quite ineffective and detrimental to the cooling capacity of your device since copper loses its effectiveness as it absorbs more heat). This is also the reasoning behind the use of Al-Cu HSFs -- the copper quickly gets the heat out of the device and "stores" it in the aluminum and while the aluminum bleeds it off, the copper component is still effective

I dont argue that lapping is not effective however just observe the CPUs in question and their operating temperatures .... using stock cooling there isnt a snowball's chance in hell the XP2000+ is running 20-25 idle temp -- even in the winter. Now for (theoretical) argument sake, assume it is running at that temperature -- when you put it under duress it jumps to 45°C -- that's a potential increase in temperature of 125% -- a clear sign of something quite wrong. No chip, from idle to stress should really be doubling its temperature and here this XP2000+ is "doubling and a bit more" (and I havnt factored in the fact its not an XP2000 but rather an XP2000 that has been OCd)

 

40-45 is a much more reasonable and expected temperature ... run something really intensive and i would not be surprised to see the chip hit the 60° mark so you might want to consider more (effective) cooling

 

Kamran: if thats all you are doing, is OCing your case really neccesary? (and 'sides would you want to risk it?)
hydr0 : the XP2800s are also a lovely bunch to OC and as for your monitor, check the actual pins on both the monitor and video card end of things -- i kept wondering why my screen was flickering green then i realized the pins were absolutely MASHED in

 

LMAO I did that last summer!!!! I still couldnt keep the temp <50ºC tho (XP2100 under stress in 30°C+ weather) ... used a damn nice superfan too! One point tho: you wouldnt need to take off both sides of the case would you? ;-)
