OC'ing a Pentium 3

[SubKamran]

I have a Biostar motherboard (M6TSU) with a Pentium III 700Mhz CPU.

I have successfully overclocked it to 924Mhz with an average temperature of 38C, where when using SiSoft benchmarks, only goes up to about 48C (highest I've seen). I believe these are safe temperatures?

Also, I'm wondering if it go up even higher, except it only let's me set the "CPU Host/PCI Clock" setting to 132 Max. (setting the Bus speed to 132).

It only gives me these options in the Frequency menu:

Auto Detect DIMM/PCI Clk | Enabled
CPU Host/PCI Clock | 132/44Mhz (Min: 100, Max: 132)
CPU Clock Ratio | x3

Before I OC'd, I made the ratio larger, nothing happened, so I'm not quite sure what that is.

Can anyone help?

48C is starting to push the limits of safe temperatures for a Intel chip.
924mhz is a 32% overclock for a 700mhz chip, which is quite impressive on its own. If you are running stock cooling on the chip, its prolly not gonna last that long, and i would suggest getting an aftermarket cooler. A good one could possibly bump that 48 down to a 41-43 which would hopefully extend the life of the chip a lot longer.

As for the Frequency ratio.. Im not very familiar with the pentium III line, or ive simply forgot. Its been a while since ive worked on one, or much longer since ive tried to OC one But most if not all intel chips have their clock ratio locked. AMD chips allow the adjustment of the Clock ratio, but with Intel you are stuck with adjusting the frequency.

But a 32% OC is very impressive none the less. Unless you were running a watercooling or vapochill type system, you arent gonna want to push the chip any further.
