Problems with my Celeron 533

[Liguid]

I can't seem to overclock my celeron 533. I have it on a Abit BH6 model motherboard.
I try to overclock and it and it becomes unstable such as when i try to play a game in the middle of the game or something it freezes up and whn i change it back to 533 it runs fine... i tried to overclock it to even 600 still unstable.... anyone have any ideas how i can overclock this sucker?

 

[toph99]

did you try changing the voltage slightly?

 

[Liguid]

yea i tried changing the volts still didn't work

 

[they call mr big]

how igh are you pushing up the voltage??? might have to go as high as 1.85v or 1.9v also what temps are you getting??? what cooling, could be overheating

 

[Liguid]

hmmm maybe i put mmy voltage too high.. it was at 2.1 2.2
i'll try to change it down to 1.9 or something
how do i find out what temps i'm getting?

 

[ingenue007]

2.1 volts? you crazy?

do you have the FCPGA one (green) or the PPGA chip?

 

[Liguid]

what is FCPGA and a PPGA?
and where do i look to tell me?

 

[Liguid]

I'm kinda new to overclocking

Here is a picture and a description of a 533 fc-pga CII.

o then i have the PPGA

The fc-pga are the newer chips. The CII 533 needs a default voltage of 1.5 volts. These chips have .18 mu spacing between the traces within the silicone itself. However 1.7 - 1.8 volts is needed to run them at the 100 mhz FSB (800 mhz). Many have posted that 1.85 - 1.9 is needed and the users are content with running them that high. Most say that any more voltage beyound that does not cause them to run at any faster speed.
The older PPGA 533 has a slightly bigger chip. Remember that the socketed package -- the little circuit board that the chip is mounted to -- is the same size either way. The older celeron runs on a default of 2.0 volts with .25 mu tracing spacing. You probably can't run it any faster than 600 mhz even at 2.3 volts.
I think older celeron chips are green and the new one's are blue. Someone will quickly jump on this if I'm wrong.

Since you have the 533 PPGA, you are kind of stucked. These chips do not overclock very well, as the core's limit is around 600Mhz. With GOOD cooling and cpu lapping, you may be able to hit a bit over 600, but the 533 is not really a good overclocker. You best hope is probably 75*8=605 which will probably require 2.2-2.3V and an Alpha cooler at the minimum (probably need a peltier to be 100% stable). The 12% gain is only a small gain so use your own judgement to decide if it's worth the investment. Good luck!

You have the PPGA Liguid, those are crap at overclocking. The most reasonable overclock you can expect is 600MHz, and even that's not gauranteed. If you can't even get it at 600MHz, then I suggest you forget it, run it at stock speed, or get a new CPU.
