Athlon 900 Overclocking to 1Ghz

I have been tinkering with my Athlon 900 for a bit now, trying to see if its rock solid at 1Ghz or not, well its not so far. BUT, I'm not quite sure if its cpu related. It ran the torture test in prime 95 for hours no problem, ran quake3 in a loop for 30 minutes when I hit quit. I left it at 1.75v haven't really jumped the voltage any. The only instabilities I had were like heavy disk activity kinda stuff, unzipping large files etc. The one thing that absolutely killed it was analyzing anands logs one day 🙂 That is pretty hard on a system though. Any ideas from you fellas/gals would be appreciated. I have the Asus A7V, Corsair Infineon PC133 Ram, WD Expert drives. 1004c bios, the fan is a cooler master.. Cpu temp was about 45-47C overclocked about 43 at 900. Thanks

Did this cause you computer to crash or hang?
 
Hung once, the other times it would cause IE to error in explorer.exe while starting...

I'm wondering if a better HSF will help this cooler master looks purty junky. CPU Temp isn't that high though 46 C or so.
 
are you running it at 1000 by changing the multiplier, or by upping the fsb to 111? the kt133 chipset isn't known to like high fsb speeds. if you've unlocked the multiplier, did you do it by pencil or by the loctite kit? the instability may be because of the pencil if you did it that way. graphite is not meant to conduce. the temps shouldn't be any higher since you haven't upped the voltage at all. the temps probably raised because of the high amount of activity. try upping the voltage to 1.8 and see if that increases stability. with that a7v, make sure you're running the system in "optimal" mode and thatyou're running the ram at 133mhz. let us know if you need more help.
 
I just upped it to 1.8v we will see what that does. I believe I am running in optimal mode already, and the ram is at 133. 30 minutes of prime95 without a single issue. BTW, I used a loctite kit to do the bridge connect so I know its done right. Running 49 C under full load.

 
If you are experiencing problems only when the CPU is OCed, then it would seem like an CPU problem since the only component that is being stressed is the CPU.

If that is the case, try upping the voltage, which I see you have just done and see if the problem persists. If that aggravates the problem further, then the culprit may be heat and you should then get a better HSF.
 
crank the volts up to 1.85 and you can go higher just be sure to keep it cool......... just read you had a cooler master get a better HSF if you can it will help alot........
 
I don't see how heat can be it after an hour of prime95 it is still at 49 C. I realize that stressing the CPU will bring out the instability in overclocking 🙂. But it was just strange that anything else that stressed it i.e prime95, decoding mpeg files, quake3 loops did nothing but heavy disk activity caused it to bomb. Anyway thanks for the suggestions.
