PIII 500 -> 650 MHz

[nitro2k01]

I know I've seen instructions how to hack a 650 MHz PIII so it'll run at its full speed. But I can't find it now... (What I remember is a well illustrated page with instructions)
Anyone have an idea?

Thanks!
Btw, another question (I don't want to start another thread for this)
I have the INET36WW BIOS. This means I have the latest BIOS revision, right?

[nitro2k01]

And another thing: If my CPU is running at 500 MHz, 100 MHz FSB now, doesn't that mean that 108 MHz FSB will yield a 540 MHz core frequency? Or is the multiplier increased to 6?

Didrik,

The multiplier will be the same (5) what will change will be the FSB (108).

And yes you got the latest BIOS.

Version: INET36WW (1.16)
Release Date: 2001/10/12

What confused me about the BIOS is that in the BIOS it says 1999, but on the page it says 2001. Good to have that clear.
I now saw that the FSB overclock and speedstep hack are separate.
I've now applied the speedstep hack, but I haven't re-assembled the computer, so I don't know if it works yet. Do I dare to make the 8% overclock as well? Will it increase heat dissipation 8% as expected, or more than that?
Is it adviced to replace the (plastic?) film on the heatsink with regular silicon paste. (That's what I have at hand) Or is the existing film better?

Same thing happened with me with the 600X.

My advice would be to get a 600X heatsink, i have read somewhere that it cools better the cpu when you do the overclocking.

I've run MM for a while to make sure everything is working fine.
First I let it run while I was surfing the net a bit, and the temp was about 50°C. (Going between 45-55°C, fan at full or almost full throttle all the time) That's a pretty acceptable temp according to me. Then I put a bit of workload on the CPU. After letting it work at 60% load for a few minutes the tmep rose to 80°C. That's when I didn't dare go higher.
Thinking about it, the table it is standing on is not very heat conductive
But still, what is an accetable temp to keep for an extended period of time? Is 70°C ok? 80?
Also, how reliable are the thermal zones on the 600E, when it ocmes to giving you the right figures? And where are they placed? (The one mentioned above was the one changing the most and going the highest. I suspect this one is close to CPU. But how close?)

Sorry to reply in an older thread (it's Sticky though), but this link seems dead. Any other place where this information is?


Thnx.
