A WONDERFUL NEW YEAR TO EVERYBODY!!!

@Dataman

Thank you! Yes, brought up one more machine (very old, has no real
function) which had silently crashed with a hard disk problem -- now in
operation again.

@blizzie et al. who do/intend overclocking:

OC thought 1:
=========
It is not advised to do over-clocking (neither main processor or graphics
processor) with PASSIVE cooling (heat sink only), you should ALWAYS do
ACTIVE cooling (sink with fan or sink with liquid cooling). Some companies
(and OC freaks) suggest fancy passive heat sinks that put your hardware
to risk.

OC thought 2:
=========
I think without thorough checking of fault handling in WCG the use of
over-clocked CPUs for crunching is irresponsible! If you operate CPUs
outside their specification (speed and/or temperature) then errors CAN
and DO occur! So this usually is only done for gaming and other "unimportant" tasks.

I'm not sure if every result is "validated" by sending each WU out more
than once -- if not, positive results can be missed!! If a result is reported
as "positive" (whatever that means for a given project) it is checked again
but if a result is (falsely!) reported "negative" (although it possibly contains
an epoch making find) it may be lost to the community!!

Same is valid for heat and memory -- blizzie, do you operate that Zephyr
machine without a case?? I often see that and people who see these
pictures might think that cooling is even improved this way. Don't be
fooled by that idea -- cases are designed to create an optimal air-flow
driven by the fans. Operating a naked motherboard reduces the risk of
heat building up as result of a fan failure but actually reduces cooling in
normal operation as you lose the air flow for the complete mobo. RAM
chips have a rather low temperature at which they begin to produce
errors and not every mobo uses ECC (memory error correction method).

So please use over-clocking (and cooling) in a responsible way and check
back with the WCG programmers if false negatives can cause a problem.
If so, it's not worth it -- given in first place we crunch for cures and not for
points.

Best regards, Stefan.

Happy New Year to all at MOT

Keith - Have you come up with a target for this year yet?


I have a few Q6600 GO's crunching away OC'd at 3.4GHz on air (Asus P5K + Thermalright Ultra 120 Extreme coolers) nice and stable and never go above 50C - you should see the speed them WU's crunch!

I've also used the Tuniq Tower - but to be honest I'm finding the TR Ultra's better.

Either way, good luck with it Blizzie

Keith - Have you come up with a target for this year yet?

You may be old and senile keith - but you are crafty and wily enough to pull those heart strings

Hmmm, for me to do 55 Million in a year I would have to average 150K a day - so its possible I guess .......now stop this right now keith, I ain't going to bite

....and of course I didn't need to look up Metastopholes either
