Hi

Sorry for my english, but i'm polander

I want to overclock my athlon

i have got epox 8krai and ModeCom LC-B300ATX

My defaults: fsb 15x 133 Vcore 1.65

I want to ask people who know that athlon and know what i can and not.

I read on ?france? forum about good configuration is 15x145 and add +5% Voltage. I calculate that ~ 1.75 V

I do that, system showed: 2179 mhz everest showed athlon 2700 +
Computer running fuster but i opened prime 95 for first test (fpps)

first minute... computer before errors was restared.
I changed previous configuration


And i have question. why compuer isn't stabile? (stable??)

I should change 1.8 V??

I want to get sure info because i haven't money for servicing that..
 
Hmm

Well I am not sure but does your motherboard support 166/200Mhz FSB? I would leave everything and set the FSB to 166Mhz if it is supported. That way, the dividers come into play and no other device should be overclocked. Try that. I remember that I had my Athlon XP 1800+ overclocked to 1.925Ghz from the 1.53 original ;) just by chnaging the FSB from 133 to 166 and left the multiplier alone.

If you decrease the multiplier to 11x (hardware adjustment), the fsb can go above 200MHz and can run up to 2400 MHz, u can set the voltage to 1.75, it doesn't need more. but there is a problem if your memory runs on a lower frequency then the fsb (example: 133Mhz Memory : 200MHz fsb) then the computer isn't stable, FSB and memory should be 1:1.
 
Hmmm

Answer this please: Does your motherboard support 166FSB? What speed is your memory running at?

SOLUTION: If it does, then setting the FSB to 166 is a better option as it does not overclock the other components (Which 145 does!).

You had 133 x 15 = 2000Mhz
Now you have 140 x 15 = 2100Mhz
You could have (easily) 166 x 15 = 2500Mhz

You may not even need to raise the Vcore.

I said few posts up, i have blocked multiplier!!!


Out of that computer on 15 x 140 and Vcore 1.75 V has been restared not when prime 95 running but when my mother played games...

Computer wasn't stabile... my mulitplier is blockd and i can't do whatever with my processor

u can lower your multiplier to 11x by little hardware adjustment, you need to connect all the L3 bridges on the cpu, then u can increase your fsb alot and get great performance improvment
 
i haven't good mechanical skill. I never going to touch my cpu :lol:
I fear to deinstall radiator, install too, so.....

If my comp isn't stable on 15x140 then why must be stable on 11x166?
and if i can't set higher fsb than 166 11x166 = 1826 :rollingeyes:
 
the best way is to go from 133Mhz fsb and go 1MHz at a time, and when it becomes unstable don't go further, increase voltage by 0.025v and continue increasing fsb by 1MHz, when becomes unstable again, increase the voltage and continue doing that, u can increase the voltage for about 0.15v from stock voltage, u don't wanna burn your cpu

i increased my vcore from 1.6v to 1.85v, temperature is 8°C higher but it's working fine
 
Just remember to constantly check cpu temperatures when raising the vcore as the AMD's run hot and the increased heat may be the cause of your instability.
 
sounds like your CPU needs more voltage. no problems running 166FSB since it's only ~1800MHz. But when trying to get 2100MHz with 15*140 your CPU lacks voltage.

i succesfully overclocked my 2400+ XP to ~2.4GHz (225*11) and i owned an Epox 8RDA3+

...sorry, but thats wrong. AMD's do not (even in GENERAL) run hotter. like what apj101 means by "compared too what exactly."

I happen to run an AMD and i can get 19C with no fan idle. sound hot to anyone? lol
