View Full Version : What's up with my Celeron 633?

I've been working with this thing for about a month and it has given me the weirdest results of any chip I've ever owned...

1) The chip is more stable at 990-1000 MHz (104-105 FSB) than at 950 (even 100 FSB)

2) The chip is much more stable at 950 when at 1.7 volts rather than 1.8 or 1.9. (at the higher voltages, Windows registry errors everywhere, reboot forced immediately. At 1.7, can actually run 3d Mark 2001, though it drops you out after a while...)

3) Errors in Prime95 Self-test when using the 2/3rds AGP divider (resulting in very slightly underclocked, between 62-65 AGP bus) rather than 1/1. 1/1, works beautifully. 2/3rds, I'm getting typical stuff: Q3A crashes after a minute or so, MadOnion stuff drops out, Prime halts self-test, etc...

At 990-1000 MHz, I've had an incredible amount of success. MPEG4 video encoding sessions lasting 12 hours, Prime95 self-testing, Quake 3 Arena, looping MadOnion poses no problem. But just a little bit below and BOOM, things go haywire.

Ambient is pretty warm. Between 34-38 C. CPU load never goes above 43 C.

Could this be a slocket problem? (Perhaps replace with an ASUS or MSI slocket?) Perhaps a finnicky video card, looking at those AGP divider results? Really appreciate your help...

Your temps seems to be very good if compared to mine (C2 600 Cb0 @907 1.8v) here ambient temp is around 30-35C and Cpu@full load works rock stable around 46C.
Probably can be the Vid card too hot, try touching the Gpu back during work.

I hope it helps you :-)

What I want to know is why my celeron goes crazy if I push it above 952mhz. Maybe it needs better cooling I don't know but this is makeing me sick. This thing could do much more than a gig if I could break this little barrier. Although I am stuck running the core at 1.8 because my board sucks I am going to be getting a new one soon. I'm thinking about an Iwill. By the way what is that one board that has a huge FSB for Intel
