Where's the thermal sensor placed?
If it is on the die itself, it'll show rather higher values than an

So there I will be... playing Company of Heroes and all of a sudden...
booom... it shuts off.

Well at least this will prevent frying damage or so... so I kinda like
it as long as it doesnt happen well I am busy with something important

So far it has not happened with anything important just gaming.

The solution for me for now is to keep the doors and windows open and
allow some cool breeze to come in... this will drop the temperature down
to 26 degrees celcius.

So my computer crashing or not crashing depands on 1 or 2 degrees.

Apperently the AMD X2 3800+ CPU is rated at about 85 watts or so...
apperently that's way too hot.

I am not happy with how CPU's are marketted today...

They all have the same name and same model number... sometimes there
will be a letter behind the cpu's model number for example for latest
intel haswell processor a T.

Apperently the T versions run at reduced clock rates, which makes them
consume less energy... instead of 85 watts it will be 65 watts or 45 or
35 watts or something.

So I was thinking... maybe it's time to ditch the AMD x2+ 3800+ crap
cpu... and switch to something else...

But this could be an expensive joke:

Probably new power supply needed, new motherboard, new memory... maybe
even new graphics card or maybe not.

What's further annoying is the cheap shit that's between the wafer and
the cpu heatspread apperently this could be replaced and make it drop
some degrees.

Not sure what happens if my finger would touch a waver if that would be
the end of it. Does seem interesting but at 35 watts or 45 watts doing
that might not be necessary.

For now I will see how it goes however... there are very hot days
ahead... so keeping the doors open might not be possible.

Right now I am thinking... maybe there still is a socket 939 processor
somewhere.... with much lower heat... that could be nice... but then me
would be a little bit worried about the performance Maybe even a
single core.

Look at his picture again.

http://www.skybuck.org/Winfast/TemperatureReadingsWith1GHZMode.png

The silicon die has at least two sensors, if you believe the picture.

As for the other four listed sensors, sometimes those are fake (open circuit).

A person should load up Prime95 or cpuburn or similar 100% CPU program,
then watch *all* the sensors, to see which ones move, which ones
move fast, which ones move slow. The fast moving ones, are
right on the silicon die. The slow moving ones are
elsewhere. The rate of change will distinguish all but
a few, such as a Northbridge sensor from a motherboard
case ambient sensor.

I doubt they'd bother with the old socket sensor tape, when
the S939 has internal diode sensing.

I have a motherboard, where a "THRM" input accepts my RadioShack
thermistor, and I use that to measure room temperature outside
the case. Not many motherboards provide a two pin header for
that kind of thing. But that's an example of what they can do with
left over channels on the SuperIO hardware monitor.

Presumably you've checked that the CPU fan (assuming there is one) is
running.

I had a problem of an overheating CPU some years back that I eventually
traced to inadequate thermal contact between the heatsink and the CPU.
Reapplying some heatsink compound solved the problem.

I remember an old white box computer I had. You could always tell when
the CPU fan died because system would blue screen you to death.

Replace the fan and all ran well until that one died.

For mini towers, there are blower type fans available that turn slowly and
move a lot of air. Those with ductwork to direct air over the processor
sink work very well. My Dell 5100 is set up that way; however, you have to
take it outside once a year and blow out all the lint and dust. Small price
to pay to keep an old box going for 7+ years.

Hmmm better ignore the 4 dots method lol..

It probably stupid...

It will probably create big air bubbles near the center which would be worst
case situation

At least the dot method pushes air out to the sides

Then again I wonder what my smearing has for an effective

Maybe a few micro bubbles here and there

At least corners well done

Settings can be changed from 45 to 55 or 60 or so as far as I know if it's
capable of being disabled I dont know.

But I like the feature... so I am going to leave it as it is.

Didn't have any more shutdown problems.

Though windows wouldn't be windows if it didn't have other problems.

Now that windows 7 is un power saver mode... the login screen will freeze up
the pc if I dont login.

Have to do a hard reset and reboot.

Not sure if this is because of a driver issue or if it's a windows 7 bug.

Getting a clean all-analog solution certainly seems harder than a clean
solution built around a micro. It sounds like you need a fairly clean
sine wave, though, which means that any solution with a microprocessor in
the middle would have to have a nice DAC, and probably filtering and
buffering.


The uC would be breaking a sweat. In order to obtain a clean sine wave
at 10kHz it has to either pump data into a port with lots of R2R at more
than 1MHz or pump the data into a DAC at the same clip. The data could
either come from a 1/4-cycle LUT (gets pretty big) or be calculated
on-the-fly (even more sweat beads). Then it has to handle all the loop
response stuff, some USB, some housekeeping.

1/4 cycle of 10kHz into a 1MHz DAC is only 25 samples. what size of
LUT do you need?

PWM-ing it could be a stretch at 10kHz.

Since we need to do very fine phase shifts at resolutions of 16bit or so
there would have to be lots of LUT sets or 25 each. Haven't calculated
it but it'll probably be in the thousands. Phase has to be adjusted to
milli-degrees.

No, I'd have to keep the phase shift at a certain value and that phase
delta value can change at any time. So it could be 87.35 degrees one
second, 87.42 degrees the next and 92.73 degrees a minute later. All
with a spiffy clean sine wave.

While you need a big phase accumulator, say 32 bits for that
resolution, however only a few of the top bits of the phase
accumulator is used to address the LUT and is used to drive the DAC.
Please remember to look at the produced sine wave _after_ the
reconstruction (low pass) filter, the truncated phase and amplitude
values will show up as increased noise levels of the output, put the
phase/frequency resolution is determined by the size of the phase
accumulator.

If you need a smaller LUT, use the highest phase accumulator bits X to
address the element in the LUT and extract some fractional bits x. In
each LUT element in addition to the sin(X) value, there is also stored
one (or more) multipliers a (and b) to be multiplied with the
fractional bits. thus

sin(X.x) is approximated with sin(X) + a*x ( + b*x˛)

This of course assumes hardware single cycle multiply (at least 8x8
bits). This will reduce the LUT table required and hence store the
full cycle, avoiding the quadrant selection.

Without good hardware multiplier, the element specific multiplier a
could be replaced with a shift count, telling how many bits the
fractional bits x should be shifted to right before adding to sin(X).

These are approximate methods, but to get exact values the
trigonometric relationship

sin(X.x) = sin(X)cos(x) + cos(X)sin(x)

Requiring four LUTs, two multiplys and one addition.

Note that for small values of x, sin(x) is quite close to x when
expressed in radians and cos(x) for small values for x is quite close
to 1, some simplifications can be done.

All very nice, but the photo given doesn't even come close to what ball
lightning is, and when I saw it, it was three distinct spheres and they
were OUTSIDE of a barn that had jut been struck. It had nothing to do
with a house or airplane. They float, so the Earth (100% negative) is
not an attractor for them, or they would fall or "attract" toward it.

The three I saw were 100 feet away from me, so that "hallucination"
horseshit the idiot spouted was total baloney as well. They were two red
spheres and one blue sphere and they hovered above the ground about 6
feet for about 5 seconds, then 'poof!' they were gone like grandpa's ol'

When I was about four years old, standing out in the front yard, a
bolt hit a tree about 60 feet in front of us. They say I jumped
pretty high.

At the same time my mom says ball lightning came though a screened
front door, across the floor and disappeared/dissipated on the into
a metal stove on the other side of the living room (about 15 feet).

I don't remember any of it, unfortunately.

100% unrelated, and pretty retarded, actually.

Why, was there supposed to be a photo of one there? if so, it was a
photo of something else, because that "blue sparky ring" they show is NOT
"ball lightning".

or is this *your* kook-self emerging?

the time I saw it was back in '73, so there were no phones or cameras
in everyone's hands then, and I was in my teens.

I do not have a cell phone now (not for nearly a decade now). I do
have a (video) camera, which I carry everywhere I go. It is a waterproof
job not much bigger than an ordinary modern cell phone.
