Great, thanks for confirming that.

I do have a fan on it, although I could probably fit a bigger quieter one in. 
I'm not interested in overclocking as such, just getting the straightforward 
best performance.

These fluffy figures probably come from my misunderstanding of the manual.
CPU Freq: 600MHz
CPU Ratio: 6x (?)
It also says: Warning: Intel 810/810DC-100 chipset supports a maximum of 
100MHz CPU FSB blah ...
I think from the jumper settings that the display cache runs at the same 
speed, there's nothing to suggest there's any value in pushing it.
So far I'm not seeing any instability, so I'll stick with this and see how it

And dropouts, right. This is now my biggest (but not insurmountable) problem, 
which can obviously be fixed by throwing some cash at it when I get some.
That's a Win AFAIC :-)

Thanks for increasing my understanding of this subject.
