It appears I was wrong, the prefetch is available on all Athlons not just
Thunderbirds, so it must be something else.

Is it possible that the Athlon that didn't see the increase was an original
Athlon (rather than a T'bird) and so didn't have the prefetch instructions?

Hi,
I also quit GIMPS a couple of years ago, after completing one Lucas-Lehmer
test. I then hopped around various distributed projects, including RC5, OGR
(before it was run by distributed, and since it has been), sum of powers
etc.
As I'm interested in prime numbers I have ended up spending mos

a - I think it may suffer from the
problem of increasing the time of each iteration, therefore even though it
saves a bit of speed on each iteration it might not cause an overall speed
up.

Hi,
Soory to be a little off topic, can somebody tell me how hot a motherboard
should be running? I have a Celeron 466 and an ASUS P2B-B. It claims to be
42 degrees after some days of continuous use. Is this normal?
Thanks,
Michael.

eron in
instead, although a 500MHz Celeron costs about £85 instead of 45, you get
back to your 37pence/MHz figure. Also note memory prices have gone up, so
32M now costs about £40-50!! Maybe this is the first time in recent history
the price of a computer has stabilised??

I have a K6-2/300, and it is much slower than a Pentium. I actually
use it for RC5 because it is so slow at LL testing, though I have a
K6/233 doing factoring work. The K6 suffers because a) it can't do
FXCH at the same time as another FP instruction (which Pentium's can),
and also it can on
