My take is SMP w/ celeron is a clever hack that seems to work (BP6 problems
notwithstanding, it's fine on dual slot 1 mobos AFAIK). On the otherhand
overclocking your CPUs means you are driving them beyond the tolerances they
were designed for. You are more likely to overheat the CPUs leading to
further problems. Your PCI bus is running at the wrong clockspeed. Now what
do you think is responsible for your timing trouble?
I don't care if you overclock, but I'm fed up of people bleating here about
their overclocked systems not working. That is the nature of overclocked
systems. The solutions include
a) shut up and live with it
b) stop overclocking
c) shut up and live with it
d) improve your cooling
e) shut up and live with it
f) increase your CPU voltage
Let's consider an analogy. My car is a 15 year old Vauxhall Astra. It has a
1.3 litre engine. Let's say I'm a genius mechanic and I manage to re-tune the
engive so it's twice as powerful. So I take my car out for a test, drive
round town at 30mph it's fine, get to the motorway and drive at 60mph. It's
still okay, now lets see how fast it goes - I drive along at 160mph and what
happens? The engine overheats because it's only got the cooling for the
standard setup, the engine mountings are starting to shake themselves to
bits, the transmission is shaking itself to bits. Next, I see a roadblock
ahead of me, so I slam on the brakes. But the brakes aren't designed to
dissipate that much energy, so they overheat and suffer from brake fade and I
can't stop before hitting the roadblock. Of course, all this is my fault
because I started driving it out of spec.
You paid for two 400MHz processors and that's what you've got. Stop whinging
about it. Be happy they work in a SMP configuration they're not rated for
that either.
