I have successfully overclocked my proccessor w/ CPUFSB (couldn't do BIOS because the computer is an HP - stupid proprietary crap!). I raised the FSB from 100 to 110. I have not been able to successfully raise it any higher. In an earlier post I thought that the problem might have been the Voltage, but now I noticed something that I thought was odd while using WCPUID. When you do View->Screen Mode, it tells you at the bottom about your RAM. It tells me that I have 128MB, which is correct, but then it says that it is running at a speed of 146.65 Mhz. Isn't the memory supposed to run at the same speed as the CPU FSB? This would then make it 110Mhz. I now believe that my memory was the component being stressed, not the processor. Does anyone know how I might fix it so that the RAM runs at the same speed as the FSB? My system is an HP 8766C if it helps. Thanx for any help

This is strictly a guess, but some boards have the option to run the memory at either FSB, FSB + PCI Clock, or FSB - PCI Clock. At 110mhz FSB, your PCI Clock would be 110/3 or 36.67mhz. If your memory is set to FSB + PCI Clock, your memory speed would be 110 + 36.67 = 146.67mhz. I'd suggest that you look for a setting that resembles what I described...no guarantee though...LOL

Not only is the memory and pci clock increased but also the AGP- Im not sure if you can change the ratio in the hp bios.

If you are overclocking using, which I belive you are...then you are increasing the speed of RAM, PCI slots, AGP slot. Overclocking the Processor is not the limit. You can overclock the processors much more than you are able to right now but overclocking is also determined by your RAM, PCI, AGP slots. These are the things that limit you to overclock low. There is not a way to fix this. If you are using SDRAM PC133 then it should run at 133Mhz but your RAM is running fine since you overclocked it.

ya the ram is the same as the sys bus but only when the ram bus is pc100mhz. if its a pc100mhz mobo then putting the sysbus at 110mhz would make the ram 110mhz, but if the ram is pc133mhz then raising the bus to 110 would increase the ram to the 140mhz range depending if its fsb+pci. most pc133mhz ram can take taht fine but i wouldent do that to pc100 ram. find out if its pc100 or pc133. if its pc100 update it to pc133 (dubble sided) or even pc150.
