Can I overclock my CPU with the following specs:

Processor is a PIII 500 Katmai(0.25) SL35E
500/512/100 2.0V S1

Mobo is an Azza 810DMC rev 2.4 (intel i810 chipset)
CPU Core Voltage Range Selection (1.3V ~ 3.5V)
CPU Voltage Adjustment (+0.05V higher than CPU voltage detected by mobo)
FSB Auto / 66MHz / 100MHz selectable
Award BIOS Frequency/Voltage Control:
Auto Dectect DIMM/PCI Clk: Enable / Disable
Spread Spectrum: Disable/0.50% (Cntr)/0.75% (Cntr)
CPU Host,SDRAM Clock: Default / 95,95MHz / 100,100MHz / 117,117MHz / 124,124MHz
CPU Clock Ratio

RAM is Generic PC-100 192MB

Any information is greatly appreciated. Thank you.
 
Perhaps a Bios update might allow you to choose FSB's higher than 100 Mhz? If not, you can't OC your PIII Katmai. Or any other PIII. If you're stuck at 100 Mhz FSB and just gotta[/i) OC, a Celly II is needed. However, a CII must run at 650 Mhz Clock Speed to ~equal your PIII's performance.
 
klosters64a -

It wouldn't work if I kept the FSB Clock Selection on AUTO? According to the mobo's manual, the FSB Clock Selection is controlled by dip switches (SW1)and allows me to choose 3 settings: AUTO, 66, & 100. It states that one can choose the CPU FSB clock for "some special purpose."

The manual also goes on to say that one can also use BIOS to select a different FSB clock to force the CPU to use the selected clock. I'm wondering if I use BIOS, are the selections from the "CPU Host,SDRAM Clock: Default / 95,95MHz / 100,100MHz / 117,117MHz / 124,124MHz"?

Would this would allow me to choose 117MHz or 124MHz (x CPU locked clock ratio of 5) for a processor of 585MHz or 620Mhz, respectively?

Also, do you know what the Spread Spectrum is?

Here is the manual's full text on the FSB Clock Selection:

SW1 is designed on the board to choose the CPU FSB clock for some special purpose. Basically, you don't have to worry about the FSB clock because it will be detected by the mainboard automatically. When you have installed the CPU onto the mainboard, this mainboard will detect the CPU type and specify the proper FSB clock for the CPU. So you need not to make any setting to select the FSB clock. However, sometimes you may feel like to select different FSB clock for some special purpose. In this case, you may use the BIOS setting to select different FSB clock or use the switch setting on SW1 to force your CPU to use the selected FSB clock. (Please do not attempt to change this setting unless you are the technician).
 
The host frequency select is the bus speed selector,and I doubt if you can get much more than 600 out of that SL35e...I have the same s code (katmai 500) and it was a chore to get it to 600, and I think it might be unstable at that speed as it rebooted during my e-mail session.
Sounds like you can choose the frequency in the bios...with that chip, I would take it one step at a time, starting with 110fsb, and try for 117, but like I said, don't get your hopes up
