No wonder my Duron was so hot...

[NFS4]

And I thought that I had a hot Duron 800 (currently at 7x136 @ 1.775 volts), it's just that damn RC5. I'm using a Taisol CGK742092 forged heatsink. The mofo was running at 49C!! I was starting to panic. I turned off RC5 and the thing started dropping like crazy til it settled down at 38 (whoah it's still dropping, down to 37, 36).

Is it a good idea to let RC5 rape my processor like that? :Q

As I finish typing this it's at 35C.

 

[Spoooon]

I let RC5 run all the time. Of course, my PIII runs a little cooler than a Duron.

 

[JJ650]

Hmm, I'm using a tbird 900 and running rc5 and my temps hang around 39 to 40 celcius.

 

[Zeeliv]

All that means it that under a full load it'll go that high, it's not like that is unique to RC5. Anything you run that pushes your proc to 100% use is gonna up the temp. 49C isn't outrageous for a duron anyway..actually for an OC'ed duron with higher than default voltage under 100% load I'd say that's pretty nice.

 

[NFS4]

Cool, I just wanted to be sure

 

[Noriaki]

My TBird runs at 50-52*C
if that's your full load temp that's your full load temp

You might want to try a better fan for your heatsink, or some better thermal grease or soemthing maybe?

But 49*C isn't that horrid for a Duron...40-45 would be better though.

 

[merlocka]

my tbird 800 runs at 52C at 997MHz, 1.85V

 

[NFS4]

Well, it doesn't help that this dorm room is quite toasty

 

[sharkeeper]

AMD FCPGA processors by nature run very warm. The 1.2 GHz Athlon has an upper temperature limit of 95°C! That's high enough to boil water in Denver!!!

Of course, you cannot expect the cpu to run stable at that temperature IF you're overclocking.

49°C is NOT by any means too hot at all! It actually sounds pretty cool to me!

If you want to make your CPU dissipate the maximum amount of thermal energy possible, try running burnk6.exe. That sob makes my processor run nearly 6 degrees hotter than Prime95!!!

Cheers!

p.s. Isn't the term RAPE  something that little Guy Under the Bridge used to use?

 

[TungFree]

ok I need 3 terms cleared up to follw this thread.
RC5
Prime95!!!
burnk6.exe

what do they do in what situations do I want them.
I did appreciate the milemarkers of safe temperatures

Prime95 is accurate because an error will instantly halt the test.

BurnK6.exe is just a small dos program. It will heat your cpu to the max and it may be producing errors but you won't know it!

What I do is run burnk6 for about an hour to really heat it up. Then I start Prime95. Once Prime95 is running (it really isn't crunching many numbers because burnk6 is hogging EVERYTHING!) I kill burnK6. This allows Prime95 to fly through the operation with the core at the highest temp. It starts cooling down quick but if the system is the slightest bit unstable at that temperature, Prime95 will bomb out. (we call it going yellow around here)

I doubt the accuracy or repeatability of the so called cpu stability tester program that everyone uses as well. I had a system run on it for a day and a half and created a certificate. It said no errors and the system was rock stable. Damn computer froze while using internet explorer just ten minutes later!

I couldn't tell you anything about RC5. Never used it.

Cheers!

That's the only thing he was good for...his eloquent use of the word &quot;rape&quot;

 

[Mem]

My crappy case &amp; 900 mhz T-bird with RC5 goes to 49c,the highest I`ve ever had is 50c, but it`s still rock stable,I also have two sunon 80mm case fans running as well,anyway if it`s stable I would not worry about it.

 

[Budman]

RC5 Rapes the cpu,no doubt about that.

 

[airfoil]

Get intel.

 

[NFS4]

If I wanted Intel I would have bought Intel...

 

[SiliconVandal]

Why would he want an Intel???!!

 

[BurnItDwn]

just make a blowhole and pop i big 120mm sunon fan right over the CPU area of the case. My CPU (duron 700 @ 1ghz 1.85v) runs at 35 or 36 with RC5 running and my mobo is around 22 or 23 degrees usually ... (ambient is about 20 to 21 degrees usually)

and this is with the Fop32 ... i know the tbirds run a bit warmer then the durons ... but 10deg is quite a difference in temp

 

[Dennis Travis]

NFS4, 49c under full load which RC5 and many games even push the CPU to is not that bad at all. Also your rather warm dorm room isn't helping the temp either. My overclocked Copermine 700 in my very HOT room was running 50c during some games and RC5. Just cooling the room better brought it down quite a bit. But 49c is fine and will hurt nothing.

 

[DanC]

<< RC5 Rapes the cpu,no doubt about that. >>


This is based on precisely what empirical evidence?

If anything running any DC project that places your system under load will point out any configuration/performance errors you may have made.

This of course would include a poor choice of cooling.

RC5 no more 'rapes' the cpu than quake, UT, 3D graphics rendering, etc.

Hogwash.

EDIT:
I have 2 Duron 600's overclocked to 900 and 950 - stable as a rock. Of course, I have very good heat-sinks and fans...

 

[Adul]

DanC, FYI, he does have good cooling. He was just concerned about it. He did mention he dorm room being a very warm, so that does make a big difference. NFS4, just run some ducting from the outside to your case and have it pre warm it for you before it enters the room

 

[Choralone]

49C isn't too hot for your CPU. I run RC5 24/7 on my main rig and the CPU stays right around 48C and that's with a FOP32-1 and Artic Silver on it. Hot is the laptop I have sitting next to me. It's a P3 600 that runs RC5 24/7. The CPU temp on it stays around 65C all the time! It's been running like this for over 9 months without a hiccup. I'd say leave RC5 running, that way your CPU stays at a near constant temp no matter what you're doing. Just MHO.

 

[networkman]

What DanC is saying is true.. to suggest otherwise is ignorance.

I have several systems with a mix of AMD and INTEL cpus, some over-clocked and others not.. and all of them run 24/7. A couple (a PAIR of Dual p3-450 systems) have been running nothing but SETI since this past April! And I've now got two other systems(a Athlon 600@800 and a Athlon 700@900) running for two months on RC5 and that's ALL they do ALL the time!

I suspect someone(or something) is either mis-reading the CPU temps or not providing adequate cooling.

 

[DanC]

Adul - just a blanket statment about it in general.

&quot;configuration&quot; could certainly be construed to include environment.

The only time I ever had a problem, was when I let my office get to about 90 degrees F. (vent Fan was off)

No intent to flame, just pointing out that it's a pretty all-encompassing statement to say that RC-5 is the culprit. It is, if anything the diagnostic test that helps to point out the culprit.

perhaps I should have said it that way.

Don't worry too much NFS4, there are programs that work the CPU harder The Distributed.net client uses some of the CPU's transistors heavily, but a lot of them are idle too. Kinda like a crippled Northstar engine rotating power strokes with dead-air strokes because it's lost its coolant. OK, maybe that is not the best car example, but I can't think of a better one right now. I don't think it is going to do any harm, some of the Team Anandtech folks are running TBirds at over 1400MHz with RC5.

Back in 1998-1999, Distributed.net ran the CSC project, a short-term project that evidently used a lot more of the CPU's transistors, because it raised the temp another 3C to 5C, if I recall correctly.
