well cool! my new processor which only cost 100.00 brand new + a 50
dollar rebate

was running about 176 deg F, i knew that was peaking, the performance
was not up to par either.

So, I got some thermal grease, which has a little bit of silver in it,
and walah! now the core is running around 122 deg F

this makes me very happy.

over 50 degrees taken off the core temperature.

can i get an amen!
 
Ummm.. Kinda...

The max rating of an AMD3000 is 149f, which you were way over. Even 122
degF is a bit close.

You should never run a CPU without heatsink compound between the CPU
and the heatsink. I guess this is what you mean by "thermal grease" so
you're probably much better off now.
Remember, tho, that 122degF is an OK state, rather than a whoop! I got
it all covered! temp.
 
Further to skotl comments
there are different type's of paste, the plain ol' white stuff you se
on amplifiers heatsinks and in TV's etc is totally useless for cpu's

You need something like Silver Arctice quality, never be tempted t
use a thermal pad as well, these are not as good as the paste stuff

Those pads just lay flat on the heatsink, the paste goes into th
un-even surfaces (if you look under the microscope). The idea is t
just use a smear and not to 'pile it on', all we are doing here i
getting the maximum face-to-face contact between the heatsink and th
chip

In a Ideal world, if the Heatsink was as flat under the microscope a
it is to the touch and looks we wouldn't need to use anything a
all...

As mentioned, I would check the CPU temp from the data sheets, ar
you using a recommended cooler/fan for that chip I ask..

"The Intel Celeron processor has a maximum operating temperature of
85°C, measured at the center of the surface of the processor core
case. Boxed Intel Celeron processors require that the air temperature
at the fan intake remain above 45°C to ensure that the case
temperature remains below 85°C"

whew! you scared me!

wonder why amd can't take the heat.

Im convinced that amd is a better processor apples to apples
in fact, the new amd has direct access to the memory, intel still
travels through the bus to get to the memory (if I understood the
specs)

This is interesting. I have an AMD running at 40c (120f). It is a
1.8ghz CPU and I am running it at 2.1. BUT, I just slapped the fan on
with the pre-applied pad. I am using a secondary fan on the board and
leaving the cover off the case to enhance air flow and cooling... but
it sounds like I can do better. So, this afternoon, I am going to
replace the pad with a thin film of Arctic Silver, of which I happen
to have a small tube. I will see if it makes a difference.

Maybe I can go from "captain" to "colonel" in my BIOS settings.

The literature is daunting and most of it has to be suspect, as it is
published by the manufacturers themselves. I chose my CPU after
posting in this group. I got exactly one response, and I bought the
exact CPU the guy suggested, because he sounded like he knew what he
was talking about.

I stressed my CPU for about half an hour before cleaning it off and
applying thermal grease instead of the pad that came with the unit...
the temperature was 41c/106f (wrong conversion above).

Then I removed the heat sink, cleaned it and the chip, and applied
Arctic Silver. After an hour of stressing, the temperature was
36.5c/97f. So I guess it works. But, I blue screened when I tried to
run at 7% over frequency (colonel) instead of 5%, so functionally I
didn't get anywhere.

not much reduction, I guess the pad was doing a good job. but bringing
it down some proves that the arctic silver is a little better.

I'll take that!

about a 64-bit os. I finally download xp-64 this morning.

my success came after I used a hotmail address when registering to
download the 180 day trial.

Now about a 64-bit processor..whew, I see them for under 300.00 (right
off top my head)
that's not crazy, (not for double speed when getting data from memory)
the 64 - bit processor, does not neccessarily think faster after it
gets the data, (it can)
but the advantage is multi-tasking, for media rich applications.

I really want an AMD, so that's what Im going to be gearing for when I
buy my components one at the time. I want a 939 socket motherboard.

here is a good presentation on the basics of what 64-bit is about.

My new setup is pretty nice, and it was cheap, or would have been if I
hadn't bought a couple of items that I decided to upgrade immediately.
But, I'll have a decent second system when the dust settles.

I can see it for databases, servers, etc., but what is there for the
consumer that takes more than 4gb of RAM?

When MS released Win 95, a 32-bit Windows was long overdue, and the
programs were waiting for it. Also the web exploded about the same
time, which added momentum. But I think MS is ahead of the curve with
a 64-bit system, which is probably good, because maybe it will
actually work right by the time people need it.

MS is trying to entice people to buy Vista because of the features it
offers in and of itself. I don't think that will work without a
decent menu of 64-bit apps that do something 32-bit programs can't.
They are coming, to be sure, but when?

Also, the Linux factor hasn't gone away. It no longer makes news like
it did a couple of years ago... it just quietly gets better, better,
better as thousands of geeks tinker away. If I were Ballmer, I'd be
damn worried.

just browsed through vistas main site, looks like they stick their
finger in a little deeper.
deeper into the pocket, our ideas, and use habits
 
The case temperature will also affect the CPU temperature to a degree
a front mounted fan blowing in helps, helps stops the electrolyti
caps from cooking..

Noted a fair difference when I had it blowing out by mistake after
had it out to clean it, gotta bear in mind we're comparing differen
mobo's, case's etc etc

Those pads are OK for TV power transistors and thats about all, the
don't fill all the gaps in the surface of the copper/aluminium like
paste does.

Use too much and you might as well use non at all, sometimes thos
pads can be a pig to remove, especially where they have been pressur
mounted after a lot of heat. Never be tempted to scratch them off wit
a metal object you don't want to mark the surface of the sinking area
Isopropanol may help and will leave the area free from grease

Aren't CPU's temperature protected....

yes they are, they shut down.

far as case being cool, I agree..every little bit does help...
(but a hot case cannot fry a processor)
a hot case will just make for overall poor performance or shortening
the life span of any given component.

Heat is a pc's number one enemy.

however, I believe you don't want your pc to set in anything cooler
than 45 deg far.
as a rule.

64-bit processors and 64-bit operating systems have been around a very
long time indeed. Something like the 64-bit Sun Ultra 1 was introduced
more than two decades ago and the last ordered accepted for them back in
1987

http://sunsolve.sun.com/handbook_pub/Systems/#EOLSystems

so they were discontinued nearly 20 years ago.

For 99% of users, 64-bit CPUs are of no benefit at all.

If you fancy a cheap 64-bit machine, buy something like a used Sun Ultra
1 on eBay.

Thus one, which is sold as seen, is complete with disk, processor, and
basically ready to go and sold for £0.99 in the UK. (~$1.50)

http://cgi.ebay.co.uk/SUN-SPARC-Ult...oryZ1486QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Just try to forget all the hype.

I'm convinced the editors of PC magazines want to tell you how good
64-bit systems are, as without their endorsement, sales of them will be
lower and so their advertisers less happy.

64-bit applications are around, but even on a 64-bit operating system
like Suns Solaris, many of the applications are 32-bit, since they run
*faster* that way (use less memory, better cache hit ratio).

So if you want an Oracle database then you are likely to find it in
64-bits, but for typical applications, there is no need.

On some AMD processors, 64-bit applications run faster as the processor
makes more registers available in 64-bit mode. That is a function of the
CPU, and nothing to do with the operating system. As far as I know,
there are no Intel CPUs which have this 64-bit bias.

I write my own software on this 64-bit machine, but don't often use
64-bits (only when it is needed).
Also, the Linux factor hasn't gone away.
Click to expand...

True, and that has been 64-bit for quite some time.

And there is Solaris x86, which is a free download

http://www.sun.com/software/solaris/

which is needs a 64-bit processor on SPARC but will run on 32 or 64bit
ones on Intel chips.

Forget the hype. My guess is that the earliest 64-bit processors were
obsolete more than 20 years ago, perhaps as many as 25. So forget all
this new hype.

My attitude toward upgrades of any kind is, I'll get it when I can't
do something I want to do. A junker running FreeDOS can handle about
90% of my activities.

Ballmer isn't looking past the next 3 quarters... he can't because
he's an ex-CFO. If he could, he'd see that he is banking on an
obsolete revenue model. MS is moving in the right direction by
developing different flavors of XP, and the wrong direction by trying
to force-feed a clunky new OS that nobody needs.

IMO.

It does with Chess already - at least according to the author of 'crafty'

http://www.cis.uab.edu/info/faculty/hyatt/hyatt.html

who is an acknowledged expert on chess software. (He has written
programs which at their time were the best in the world at playing
chess). It happens to work well with chess, as each square on the board
can be one bit in a word of the computer. (It is unrelated to any memory
usage).

But that is a rare exception rather than the rule.

I expect there will be lots of 64-bit games that are written as 64-bits
just for marketing purposes. It would take me under 10 minutes to write
a 64-bit version of noughts and crosses!

You in isolation will not need it. But if some jerk down the road starts
sending you files in "Word-64" format, then you might need Word-64 to
open them. And of course Word-64 is likely to need Windoze-XP-64, or
whatever MS have chosen to call it. To me, that is how MS will force
upgrades.

i agree, but isn't bigger numbers simply better.
suppose it was 128 bit wouldn't that mean something?
suppose the circuits were larger carrying more power?

truth is? i just want to have my own holodeck

then I can order up, say... Lucille Ball or Ward Cleavers Wife, and
uh... maybe Wilma Flistone once in a while, hell, maybe even Betty
Ruble.

Hi Davy,

not wishing to appear defensive, but "generic heatsink compond" aka
"plain ol' white stuff" isn't totally useless on CPUs. Heatsink
compound can be used between CPUs and their heatsinks as long as the
measure is, ummm, circumspect. Too much means the heatsink is too far
away and too little is just, too little. However a decent application
of heatsink compound is a "good thing".

Definitely take issue with "totally useless for cpus"....
