Yes you have if you think i'm going to spend money on a cpu and the turn it down so it doesnt overheat....

Turn it down? Voltage reduction can occur without any underclocking.
The key is to choose the speed YOU want/need to run the CPU, and
giving it only enough voltage to retain stability at that speed, as
any additional voltage increase beyond that only serves to increase
heat output.

For example, earlier in this thread I mentioned a Palomino Athlon
XP1600 I had which was undervolted to 1.6V (from 1.75) and o'c to
1.6GHz.

reality check....first your saying that everyone is going to have those options in their bios 2nd even if they did all they would
have to do is have an Intel chip, OEM cooler and the machine runs for 4 years. There is absolutely no need for the average user to
have to go through any of what your saying to have a long lasting, cool running, stable machine. Can it be done? yes is what your
saying true? most of it....the big question is WHY? I have abused My PIII in the garage-90+f ambiant temps, stock cooler, filthy
inside
4 years so far......

Why do you have your PC in the garage? Mommy catch you masturbating in

I never claimed that everyone has these BIOS options. Anyone spec'ing
their own components can choose. I have presented yet another
possible reason to want these BIOS options, beyond just overclocking.

Even so, there are multiple other methods for adjusting voltage for
most any motherboard, just not as easily.

I certainly don't recommend that EVERYONE undervolt, only those
informed enough to make an intelligent decision, and still, it's a
decision. It is NOT the ultimate answer to anything, is only another
method to tweak a system, finely tune it, but also has real benefits
directly adressing one of the biggest problems facing Intel's high-end
and near-future desktop processors, that they create never-before-seen
amounts of heat, and more strain on other components like the power
supply.

Consider your PIII box... already 4 years running. A newer
motherboard built to the same price-point, grade of onboard
components, will not last as long, because the power usage went up...

And of course you can present statistics which demonstrate this
reduction in service life? No? How about some calculations? No? How
about a good white paper from a credible source? I thought not.
a bit like burning two candles, but one with a longer wick so it burns
hotter, faster. A new system bought today should have enough
performance to be viable for even longer than the PIII did/does,
possibly a LOT longer,

You assume that new applications which require more computing power will
not be developed.
except that it's lifespan isn't expected to
match, seems to be going DOWN compared to Coppermine boxes.

Evidence? Didn't think so.
In the past year or so I've seen QUITE a few posts about dead/dying
semi-modern systems... a lot more than back in the PIII days, and at a
greater rate than these (now older) PIII systems are failing today,
which is backwards, the older systems should be failing more often
being nearer the end of their lifespan.

Do you really believe that counting postings on USENET and comparing
with several years ago tells you anything about reliability trends? Or
did you even bother to count?

But for my P4 2.4 GHz why go to all that trouble of making a huge home
made passive cooler when I can achieve my requirements with a nice low
noise fan and undervolting?

Why should I undervolt when I can achieve my requirements with a nice
slow fan and no undervolting?
 
On Sun, 12 Oct 2003 09:25:40 GMT
Wrong. The need is based on the cost and weight of the passive
coolers compared to ease of undervolting along with a low noise fan.

It is customary to put all of your thoughts concerning a particular post
in a single response to that post.

Fine, forget passive coolers. Please explain why you are unable to cool
your 2.4 GHz P4 with an off-the-shelf heat sink and a Papst 8412NGL
without undervolting.

Trust my life? What are you on man?
Can you say "shifting the burden of proof"?

Yes. I can say 'Supercalifragilisticxpealidocious' too.

Wrong. Just because passive coolers were constructed for AMD CPU's in
the past doesn't mean that passive coolers can easily be created for
the newer, hotter Intels (or AMDs).

Of course they can--add a couple of more heat pipes, use both sides of
the case instead of just one, . . .
Exactly the point of using alternative cooling solutions.

Uh, custom built passive cooling devices _are_ "alternative cooling
solutions".
Wrong. Trying to sell it as something else does thousands of people a
service.

In what way?
That's why, for example, motherboard designers allow
features like "automatic overclocking". They wouldn't provide such
features unless it was providing many people a useful service.

Reading comprehension a bit lacking? Is is your contention that running
a CPU outside the manufacturer's specified operating range is a normal
procedure and that a reseller selling machines so constructed without
informing the purchaser is behaving ethically and that such machines are
to be trusted with mission-critical tasks?

Hint--"x does nobody a service" is a different statement from "claiming
thus and so about x does nobody a service".

Wrong. There is a growing perception of need for it. Evidence is
this discussion. Also see
http://www.bluecouch.com.au/reviews/nf7s/nf7s.asp or just Google for
"undervolt heat cpu".

A few of hobbyists talking about their projects does not constitute a
perceived need to undervolt anymore than a few automobile enthusiasts
their land speed record attempts constitutes a perceived need for
supersonic rocket cars.

In any case the guy you linked says up front that the board he started
with was running things considerably _above_ the manufacturer's
specified operating range.
And if I purchase a quiet fan and my system is still running on the
hot side of the specification, then rather than spending more money on
another cooling system (ie expensive water cooling system) I'll be
happy to see if undervolting can help.

Personally I'd try a little bit more powerful fan. The second quietest
fan on the market moves a good deal more air but is still very quiet.
Wrong. Plenty of non-engineers run their systems out of spec (ie
overclocking, overvolting) and they know what they are doing.

Yes, many of them know what they are doing, and one thing that they are
not doing is using those out-of-spec machines for mission-critical
tasks or recommending that others do so.
They
also know the consequences (ie shorter cpu life).

Yes, the ones who know what they are doing are aware that there are
consequences and they are also aware that the fact that their machine
posts and runs a few tests without crashing does not mean that it is
ready to be installed as a mission-critical server whose failure would
cost large amounts of money or an engineering-design workstation in
which inaccurate calculations could cost lives.
 
On Sun, 12 Oct 2003 10:02:27 GMT
Wrong. Undervolting can allow a fan to run slower, which makes it
quieter.

How does undervolting a processor make a fan run slower?
 
It's like overclocking I guess--some people do it because they can.
With passive coolers available for every processor currently on the
market though there's no need to do it to achieve a quiet machine
though.

But for my P4 2.4 GHz why go to all that trouble of making a huge home
made passive cooler when I can achieve my requirements with a nice low
noise fan and undervolting?

Well, actually passive coolers have been constructed for AMD CPUs. And
since "everybody knows" that "Intel runs cooler" there should be no
problem doing the same for an Intel.

Wrong. Just because passive coolers were constructed for AMD CPU's in
the past doesn't mean that passive coolers can easily be created for
the newer, hotter Intels (or AMDs).
Not off-the-shelf items but it has
been done.

Exactly the point of using alternative cooling solutions.
Running a CPU or any other component out of spec is something you get
away with, not correction of an error on the part of the designers.
Trying to sell it as anything else does nobody a service.

Wrong. Trying to sell it as something else does thousands of people a
service. That's why, for example, motherboard designers allow

The primary reason that "people don't as often undervolt" is that there
is no percieved need for it.

Wrong. There is a growing perception of need for it. Evidence is
this discussion. Also see
http://www.bluecouch.com.au/reviews/nf7s/nf7s.asp or just Google for
"undervolt heat cpu".
I see. So the alternatives are to undervolt or to "sound like a leaf
blower"? Sorry, but now you're engaging in hyperbole. There are a
number of heat sinks on the market which can be used to cool any
processor currently in production using the quietest fans currently in
production, without operating the processor at a voltage level outside
the specified range.

And if I purchase a quiet fan and my system is still running on the
hot side of the specification, then rather than spending more money on
another cooling system (ie expensive water cooling system) I'll be
happy to see if undervolting can help.

Yes, it works fine if you _know_ _what_ _you_ _are_ _doing_, which means
that you are an electrical engineer with IC design experience,
an intimate familiarity with the particular device under
consideration, and you know what constitute the worst cases
that need to be tested to confirm reliable operation.

Wrong. Plenty of non-engineers run their systems out of spec (ie
overclocking, overvolting) and they know what they are doing. They
also know the consequences (ie shorter cpu life).

Well, actually, a quieter fan is the only alternative since no matter
how much you undervolt if you don't put in a quieter fan the noise level
doesn't change.

Wrong. Undervolting can allow a fan to run slower, which makes it
quieter.
