when I had an amd it was directly under the cpu. So when pressed in it comes
into contact with the centre underside.

Did it occur to you that posting similar questions in many
different forums is a waste of people's time? This may seem
harsh, but the benefit of providing more information is to
you, because you still have not resolved the problem and it
is largely because of lack of information provided and
feedback on what you have already tried to troubleshoot and
rectify the situation.

Did it occur that you might just start out by providing all
the information in your opening post, for example that you
had read 53C and commonly went up to 66C with a Venice
Athlon 64 on an Asus A8S-X board.

There has been ample feedback in the past about temps,
overheating, stress testing.

First, what heatsink are you using?
Is your board throttling back the fan speed? If so, a bios
setting may be determining what it's idle speed is, that if
the CPU is cool the fan just slows down to reach an
equilibrium. To many people, this is desirable as it
reduces noise, fan wear, and dust buildup. That would be
fine at 53C, but the processor is getting a little high at
66C IF the temp reading is accurate.

LM99 is probably your video card temp, but you didn't bother
to make a concise but complete list of all major parts, so
once again you are wasting your time and our time and the
time of those in the other forums you've posted to. You
might have also mentioned what temps each sensor was
reporting, and the software you used to get that reading.

Since the temp seems high at 66C, try a newer bios if you
hadn't already, it may refine or correct inaccuracy. If
that is not a correction, take the case side panel off and
point a fan into the system. If this helps significantly,
you need to improve your case airflow.

If it only helps a tiny, insufficient amount, try taking the
heatsink off, reapplying the Arctic Silver but only a tiny
bit in the center of the processor - not spread all over it
like frosting a cake. If you have trouble mounting the
heatsink, take your time... if necessary, pull the board out
of the system to install the sink, or if the 'sink is bad
you might consider replacing it with something else.

As for your comment on another forum that "I'm likely going
to have this cpu FRY and end up spending $150 just to get to
the technology I am at now", no, your Venice 3200 is worth
about $40 brand new,
http://www.newegg.com/Product/Product.a ... 6819103567
even less now that it's used and aging technology. Beyond a
certain point of checking and stress testing, it will not be
worthwhile to keep fiddling with it if it tests stable (in
Prime95 test mentioned below).

If these things do not result in lower temp, check your bios
for a processor voltage, vcore setting, and the
hardware/health monitor bios menu showing the CPU voltage.
I'm not certain but think the stock for that chip should be
about 1.4V... slightly more or less than this is not a
problem, but if it is reading at 1.5V or more than may cause
the higher running temp.

Finally, run a stress test like Prime95's Torture Test, the
Large In-Place FFTs setting. Leave that running for several
hours or until it shows errors, whichever comes first. Also
monitor temps periodically while that is running and note
the peak temp- ignoring idle temps. If it runs for several
hours without errors, and if you have checked all the
aforementioned things, ALL of them, then there may not be
anything more you need to do.

Asus Probe appears to be using "IT8712F-1" as the sensor.

I wonder about this one too. I use Speedfan, and am pretty sure the
IT8712F-1 is CPU temp, because the "AMD K8 (Core)" seems too low. Right
now the first reads 60c (hmmm. bit warm today; usually it's closer to
50c) and Core reads about 48, on my AMD Dual-core 5600+.

On mine the "AMD K8 Sensor" rises FAST to any actions I perform. But
the IT8712F-1 rises much Slower to things I do.

I guess the slower rising sensor is the accurate one?
Or is it just as plausible the fast rising sensor is accurate?

As an example, IT8712F-1 "creeps" to 55-59C using SpyBot.
But the "AMD K8 Sensor" IMMEDIATELY JUMPS to 55-59C when SpyBot is
running.

kony?

IIUC there is no way for SpeedFan to identify which reading applies
to which sensor. The subject's been debated on the SpeedFan forum
before now. Alfredo has provided some guidance on his website which
is usually ok for folks with 2-3 sensors but where you have multiple
sensors, it gets more difficult.
What's really needed is more info from mobo manufacturers to ID
the sensor names and what they monitor...

Please bear with me on this one folks.

I simply am asking which sensor is probably/likely accurate

I'm no longer asking about acceptable temps [But I do appreciate the
help everyone gave me on that one]

Here is the scenario:100% Full Load Using SPYBOT for about 8 minutes.

Which Sensor is accurate? Which one should I be using?

You should be using the K8 Core temp report, as it is
showing itself to be the temp of the die by changing so
quickly to a change in load.

I don't know for certain that it's accurate, but it is a
starting point.

Also something that doesn't help matters. They gay hsf fan stays at
6300 RPM no matter what the temp goes to. I guess it's just that old?


Man I need to upgrade so bad.

Old? That's probably the max the fan can run at, if your
processor were cooler it "might" run at lower speed, if it
has an integral thermal throttling circuit or the
motherboard does... which it seems to since Asus does
advertise it has "Q-Fan". Have you ever set Q-Fan in the
bios to the temp thresholds you want? First, the key is
getting the processor temp down so there's margin to
throttle down the fan.

Alternatively, you could just replace the heatsink with one
using a larger lower RPM fan... that is the usual way to
achieve quieter operation, though your present 'sink (if the
retail one??) should be keeping it cooler than it is which
would allow for it to run below 3K RPM at least... or until
you did something at high load but Spybot is not such a
large load, running a stress test like Prime95 will get the
CPU hotter than spybot will (I just checked this to confirm
it).

>
>Man I need to upgrade so bad.

With all due respect, you're freaking out for no reason.
Take the 'sink off, examine it and the processor, and apply
a fresh tiny half-grain-of-rice sized blob of heatsink
grease on the CPU then remount the 'sink. Either the temp
sensor reading is wrong, the case cooling is terrible, the
vcore is too high, or the heatsink and/or grease isn't
installed right. NONE of these factors are addressed by an
upgrade, except maybe if the case is terrible and you buy a
new case, but you can do that now and still use the present
parts till you feel like upgrading them as well.

There is no need to speed all this time on what is a simple
matter. There is no need to upgrade because of any factors
you're dealing with. Even if the case is bad you can just
take whatever measures necessary, but you haven't ever
bothered to tell us what you HAVE tried to do, so this was a
pointless discussion. Keep in mind that other people do run
skt 939 A64 without these problems you feel you have.

Yes I must admit to not taking any steps you suggested. It's a little
phobia I have about putting that hsf back off then on again.


I will write again once I try something, maybe then you can help more.

The K8 sensor is the on-die sensor. It is the most exact
one in any case.

The other ones may or may not monitor CPU case temperature,
depending on what the manufacturer of the mainboard chose to
implement.

Ya I tend to trust what Asus uses to monitor the CPU temps. On my s939
Asus A8N-E the IT8712F reading in SpeedFan is exactly the same as what
Asus PC Probe shows.

On my A8N-E the K8 Core reading is always about 5C lower at idle and is
a little more sensitive when under load.

Scenario again is running SpyBot for approx. 5 minutes. With 100% Load
on the CPU.

As you can see, CORE on SpeedFan represents "AMD K8 Sensor" and is not
being displayed on Pc Probe provided by the motherboard maker asus.
http://img100.imageshack.us/img100/721/imstupidhz7.png
The "IT8712F-1" sensor is shown on the left as TEMP1 and is exactly
the same as the PC PROBE temp on the right.

I have to assume the "IT8712F-1" reading of 54C is correct since it
represented in both PC PROBE and speedFan??

Also of note the CPU Fan speeds. Notice how Pc Probe records a speed
that is nearly HALF the speed represented in SpeedFan. I cannot locate
the correct RMP sensor in Speedfan to equal that represented in
PcProbe.

This is all messed up. More likely *I* am all messed up.
Also notice those Voltages in the lower left..Anything of interest?

I'd really appreciate some comments on this new graphic.

thanks guys

You should be able to look at and hear the fan to determine
if at 3K or 6K RPM. The current rating on the fan label is
also a good clue, with a 3K RPM fan tending to be rated for
about 0.14A and 6K a lot higher.

There is little of interest, the one thing you needed to do
all along you still have not done or mentioned - running
Prime95's Torture Test, large in-place FFTs setting for at
least an hour.

This is important to reach a higher temp than spybot causes,
and to check the calculations underway for errors. This is
important, a processor will generally produce errors from
overheating long before it is hot enough to be a permanent
damaging state. If running too hot it can produce random
errors very hard to track down otherwise, leading one to
suspect buggy apps or bad power or all kinds of other
suspects until it is realized whether the processor stays
cool enough to run stabily.

While it is true you can't assume two hardware monitoring
apps can run at the same time, they may... for example when
I ran the latest version of speedfan to see what it was
doing on a board here, I already had MBM5 running and they
peacefully co-existed.

IIRC, that was the reason the fellow who made MBM stopped doing it, because
of the runarounds and hassles he received trying to get the information from
the manufacturers and vendors.

I thought MBM was discontinued?

Will the MBM work with this A8S-X board still?

I have 3 of the 8712F's, one of those temps is false reading -128C.

Yes this is puzzling, at least to me ,,
