Overclocking Problems

[Guest]

I have a tyan S1837 thunderbolt mobo. I upgraded my bios to 2.00.07A, Im running a 2x PIII 500mhz slot 1 processor, and a IBM 256MB PC100 RDimm with a #9 pci video card. I overclocked the processor bus to 103mhz and the processor runs at 500mhz and works fine.Then I overclocked the processor bus to 112mhz and the processor runs at 550mhz and works fine, it'll boot up into windows 2000 with no problem.Then I tryed to overclock the processor bus to 124mhz and the processor will run at 650mhz but the system will not boot up.And once again I tryed to overclock the processor bus to 133.3mhz and the processor will run at 667mhz but it still will not boot up, after the system or bios does all it system checks it lock up, it will boot up into windows 2000 at all. When trying to overclock it at 124mhz or 133.3mhz? I can not get it to do any thing after that. If any can help me, It would be most heplful. Thanks JP.

You have a Katmai core P3. 2.0 volt 512 kb L2 cache. Most do not overclock very well, but some do.
Try raising your voltage to 2.2 or 2.3 volts.BE SURE TO KEEP AN EYE ON TEMPERATURE!! this will help sometimes. You may also want to increase the latency of the L2 cache from 8 to 9 or 10 with WCPUL2100. exe from<A HREF="http://WWW.H-ODA.com" target="_new">http://WWW.H-ODA.com</A>

You loose. Most Katmai processors will not go over 600MHz. The few that will are lucky to make it to 650. The chances of you have TWO processors that will make it to 650 are less than 1 in 200.

Just for Guffaws, try the 124mhz FSB with PC133 memory CAS 2 or 3 with the CAS set to 3 in the Bios. I have found a few PIII Katamis that will do this trick, with luck.
Myself, I run a PIII 450 at 558mhz with the FSB at 124mhz, and the PC133 SDRAM CAS 3 memory at CAS 2 since the slightly slower speed allows the faster CAS setting and gives more performance increase than the loss of 45 or so in CPU speed.
My 2 cents. Good Luck, Take-Out.
