Please answer me -- overclock but undervolt -- safe? How much?

Hi:

Please answer my questions below. Please don't neglect this message.

Is it possible to significantly decrease the heat generated by a
"Pentium 4 570J/670 3.8 GHz processor" by using extreme undervolting
without underclocking? How far can undervolting go before it causes
trouble? What problems can result from undervolting? Can it damage the
CPU or other parts of the PC?

Also, can these processors be overclocked to 4 GHz while still being
undervolted to the max tolerable? Does overclocking decrease the extent
to which undervolting can be safely performed?

In addition, what is the max that these CPUs can be overclocked without
damaging them or decreasing their lifetimes?

No offense but please respond with reasonable answers & keep out the
jokes, off-topic nonsense, taunts, insults, and trivializations. I am
really interested in this.

If I am not answered properly I might go insane and do something
everyone -- including me -- will eternally regret.


Thanks,

Radium

Why would you want to do this? Just vent your case adequately and choose an
appropriate hs/f for the unit. I've seen reviews where a 670 did just under
4.4Ghz with stock voltage and a Zalman 7700 cooler. And they were perfectly
happy with the temp of the CPU both stock and o/c. If you must, reduce the
vcore incrementally and test for errors. Part of the huge power consumption
of the 600 series is the 2mB of on-die L2 cache. This unit consumes over
160W under full load.

Probably if you undervolt you'll have to underclock.

I have a 630 (EM64T_3ghz) that has been running at 3.6ghz for 2yrs or more
at stock vcore very happily, but any lowering of the vcore causes immediate
instability. These processors are "on the edge" so to speak from the get go,
so expect to underclock if you reduce the vcore. They also tend to run a lot
hotter than today's Core 2/Quad processors so good cooling and airflow is a
must.

Thank you all for your responses. Sorry I was harsh. I was having a bad day.

I hate to be such a pest but I have a few more questions:

Of Intel's Pentium 4 570J 3.8 GHz processor and Intel's Pentium 4 670
3.8 GHz processor, which one is less expensive?

What is the least expensive motherboard that is fully compatible with
Intel's Pentium 4 570J 3.8 GHz processor?

What is the least expensive motherboard that is fully compatible with
Intel's Pentium 4 670 3.8 GHz processor?

Which motherboard is less expensive?

What the least expensive HDD that is fully compatible with Intel's
Pentium 4 570J 3.8 GHz processor?

What the least expensive HDD that is fully compatible with Intel's
Pentium 4 670 3.8 GHz processor?

Which HDD is less expensive?

Asked and answered the first time you posted. And, by the way, you don't
set the terms of a conversation here. A newsgroup is a group effort. Most
participants in this group are very helpful and polite. In fact, yours is
the most objectionable post I've seen here in years.

Sorry for my impatience.

I didn't feel like making the effort to trim the initial post, so consider
that my post came to me in a dream from Unknown Kadath

It's amusing to see that sort of complaint from someone top-posting.

If you drop the voltage to the CPU you may fry it because it will try to
draw more current in order to run itself, and, then, toast. NOT a good
idea.
