I am not sure just what is the best way for all this to work. I do not know
what a return of 6 means (not recognized?) or how to fix it. I can find no
similar mention anywhere of the fact that power is increased and not
lowered by the use of powerd or similar and thought that would provoke some
hints and more discussion because it is intriguing and it self negates its
own purpose and functionality.
I am trying to ascertain the viability of this motherboard w/ regards to
getting the power function working proper and am constrained by the lack of
monitoring tools vs what cupid.com has for win with hwmonitor and cpuz
(they have a dev kit also). Would another brand/model of mb work better? I
know that most all are lacking in acpi function in diff ways. Maybe I am
squeezing water out of a rock, that the cpu is at its min or 6 watts now,
but I just do not know. Btw: Intel is blowing out all 775 type chips. Today
is about the last day. They want everyone on I3/I5 etc but they are not as
functional re low tdp as 775 chips.
Just because you lower the freq by stretching the clock or actually
lowering the freq does not result in a lower TDP. I do not think that the
multiplier being lowered in this case. What appears to be happening is that
the cpu gets busier and that increases the tdp over not using it at all
making it less than useless in my case.
I can find very little comprehensive info on how the eist/est//p4tcc/powerd
thing is supposed to work. Reading source of powerd is not helping.
Logically, if the voltage is lowered then the power is going to be lower.
Is the voltage a function of the load automatically controlled by hardware
and/or the bios or is it supposed to be an artifact of the freq being
lowered by something like powerd? I believe the former for the latter is
not working. I now have everything relevant in the bios enabled.
est appears to be not working but what would happen if it were working? Is
that the key to lowering the TDP when the freq is lowered? Then what is
required for it to work? Where would I find the source in the tree?
p4tcc appears that it is a failsafe for thermal runaway and since my temp
is 26 - 30 or so all the time then it would be of no use because there is
too little differential.
I csupd to stable and rebuilt and there is no difference w/ this prob. I
did see that I went from SATA150 (it should be SATA300) to udma100 sata but
that is for another thread.
I changed hw.acpi.cpu.cx_lowest=C1 to C3 and that saved me about 1.5 watts
w/ powerd but it is still a watt higher than without powerd running at all.
Does anyone know of anything else I can try or is this the best it can get?
