 Posted: Sat May 03, 2003 4:42 pm Post subject: Athlon 2500+ (Barton) and it's temperature... |
 |
|
Hi! Just got new CPU and I have no idea about how hot it should run. During full load (emerge a-lot-of-things-cause-I'm-rebuilding-the-system) I get 50-52 C @ 4100 RPM with my Thermaltake VOLCANO 9. Funny thing is that if I run it att full RPM (5100) the temperature is only about 2 degrees lower. So I wonder if I can run CPU in 52 C or if I have to set the fan on max speed and put my headphones on...
What do you think??

I have a very unventilated older Athlon that's been running @ ~54C non-stop for about 10 months without issues. That's probably not the best thing in the world, but it can survive.
If you're worried, don't bother with your heatsink fan so much. Instead get a better case front fan (Antec makes some quiet ones that push a decent amount of air) and move some of the clutter out of the way (I use electric tape to stick cable/wires against the case side) so you have a clear path of fresh cool air coming in from the front of the case. Airflow is just as important as the heatsink stuff. |

Right, thanks for the tip!
BTW, how about CFLAGS?? I have "-march=athlon-xp -O3 -pipe" . Anything else??
Cheers,
Jacob

50~52C at full load doesn't sound like a problem to me. Save you ears, they're more important than 2C of cpu temp. AMD specifies maximum die temp at 90C. Your die may be a few degrees hotter than the motherboard shows, but it's nowhere near that.
CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
works well for me. |

Good, thanks =)
Now I'm going to overclock it a bit, should run @ 2Ghz without a problem, I think....

As far as cooling goes, for cable routing I recommend small zip ties instead of electrical tape, because once the tape gets older and warmed up in there awhile it will make your wires and case gunky. I'm also trying these little 3m plastic hooks with an adhesive with a pull tab for holding wires, they still stickin to the case after a week
For cflags some add -fomit-frame-pointer. Breaks debugging but supposed to run (a little?) faster.
Oh, and IIRC, the newest athlons (thoroughbred B + barton?) are rated 85C not 90, if that matters.. |

My athlon mobile goes up to 80C before the fan starts. 
The notebook gets pretty hot underneath sometimes..
AMD is generally hot. If you want a colder CPU, get a Celeron or P4. |

No...it's not that I want a colder CPU, I don't want to run P4, nor Celeron (no way man...). I just wanted to know if it's normal and if I can run this CPU in about 50 Celsius and still have it a couple of years...
You see, before this AthlonXP I had a PIII 450mhz which didn't had any thermistor so I don't actually know what temperatures are normal for idle respective full load states. That's why I ask =)

Cheap, yes. But great? Dunno....I just don't trust Celerons and Durons for my power user workstation. Gentoo deserves a great CPU, I think

Celerons aren't super CPUs but they are damn stable, need almost no active cooling and are cheap. My server uptime was once 60 days. That's the longest I had a computer not rebooting.
For stability and long uptime. I only trust Intel CPU. AMDs just get so darn hot I'm afraid they start a fire og just fry one day. |

This is not true:
http://www.anandtech.com/cpu/showdoc.html?i=1718&p=4
Celerons produce the most heat for the performance, by far (of recent processors).
A Barton 3000 is 74 watts while a P4 3.0 is 82 watts.
Here's another site with more info, a little harder to read since there's so much listed though:
http://users.erols.com/chare/elec.htm
There is no magic chip that uses less power. An Athlon XP 1700+ thoroughbred comes in under 50 watts, so does a Pentium 4 1800 willamette but a Barton 3000 at 74 watts is a hell of a lot faster ;)

50C is totally normal. AMD CPU's with stock AMD heatsinks on them usually sit in the low 50's. |

hmmm.. I have this exact cpu you mention
Barton 2500+ (defualt speed of 1800mhz @ 1.65 volts)
I am running it at 2.2ghz (200fsb x 11) 1.75 volts
it NEVER goes over 40 degrees celcius.
and that's with my volcano 7+ on the SLOWEST speed
so yours seems a little high to me...

Which ones? This is just a biased generalization.
My main computer is running an AMD K6-3 450 that has been overclocked to 550Mhz its entire life. It's ran nearly 24 hours a day for what 4 or 5 years, and it barely gets warm running seti@home constantly. It used to run windows 98 for over a month between reboots and I'm sure it would run gentoo for months probably years without rebooting.
Only AMD cpu I know that runs hot is the 1 Ghz slot A athlon, that one really warms a room up nicely. This particular cpu survived a fried Abit motherboard due to bad capacitors, and also survived the cpu fan being accidently unplugged for days  The heatsink was hot enough to fry an egg (and fingers, ouch), and it was still running, and still is running over a year later.
Yea, 50-52C sounds cool to me, assuming the thermistor is reading accurately. Room temps and case design/fans can have a big effect on cpu temps too. Cpus are pretty durable, it's not like it's going to fry if you run it 2 degrees warmer.
Dunno about putting volcanoes on your cpu, myself i picked the vantec aeroflow for the new 2700+ toy. |

| that seems a bit high to me for a Barton. My Barton 2500 is at 99F idle (that's what like 37C?), 108F load, with a volcano 9 at full blast, and it's overclocked to 2.13ghz. Hopin when my NF7-s comes this week I'll be able to get it higher. Then again I do have 3 80mm fans in the case too. |

You're probably reading the motherboard temp (even if whatever you're reading is calling it cpu temp). An XP2500 Barton pumps out 68 watts and a volcano 7+ is a mediocre heatsink at best since the way it's designed there is a large gap between the fan and the heatsink so most of the air just spills out the sides.

Typical power consumption for a k6-3 450 is 12 watts and it peaks at 20 watts so no surprise it doesn't get all that hot. |

perhaps this is the case, however I do work with computers for a living, and I can tell you that the heatsink is hardly hot at all.
If I was not reading an incorrect temperature, then surely the heatsink would be hot.
have you had different results with a barton cpu?

I also have the Volcano 7+ heatsink.
Quotes about it being a mediocre heatsink are simply not true!
V7+ is in the better end of heatsink and ideal for overclocking. It is made out of pure cobber and with many fine wings. Really ark work!
My p4 1600@2000 is 38/44C at 0/100% cpu usage. Got no compiler errors ever.
Though, when I oc'ed to 1,6@2,4GHz I got a disk crask twice and had to reinstall windows and linux twice. NOT FUN. I think it is my HD that can't handle the oc'ed bus.
Fun story:
I once had a 486 I was about trash. It was in the days when there was no CPU socket security. So, just for fun, I rotated the CPU 180 degrees and swiched on, just to see what would happen. 
The first 5 secs the computer kinda sound like... well... not normal. And then *smoke*. LOL!
I'm a bit nervous about M$ buying all CPU manufactures to spread their palladium crap- soon, we won't be able to run linux.  |

the amount of air flowing through the case has a huge impact on CPU tempatures than the speed of the fan.
i've got two exhause two intake and a zalman CNPS5000 heatsink
similar to this, http://www.zalman.co.kr/english/product/cnps5100Cu.htm , but id ont have that cool fan controller
my CPu runnin at 180fsb on a 12.5 multiplier stays cool (~50c) after encoding DVD->divx for like, 8 hours straight.
I also got this for my video card http://www.zalman.co.kr/english/product/zm80a-hp.htm |

Shit...this looks intressting...However, as Malakin mentioned, are you sure you're reading the right temperature? Cause my sensors shows two, (actually three, the third has a temperature of 208.0 C all the time!! but I guess it's just beacuse I don't have any third thermistor) temperatures, the one is (CPU load 0%/100%) 19C/24C which is the thermistor located _next__to_ CPU and 34C/52C which is the one located _under_ CPU socket. All temperatures @ 4100RPM from my Volcano 9. And would you please tell my what MoBo you're using? And do you have any other fans in the chassi?
By the way, you all mention Volcano 7+ and lower temperatures. I thought Volcano 9 was next generation of Volcano series, isn't it?? Is 7+ better then 9 ??

yeah the Volcano 7+ is the better of the two, it's also slightly more expensive, 100% copper base and fins. Volcano 11 is out too.. dunno how good it is.
I am definately reading the temperature correctly, because the heatsink hardly feels warm at all, and I've been using athlons since b4 they were released so I'm sure it's all good. Secondly, another guy comfirmed how cool his barton is running. do a search on google and see how hot they are running around the world, you'll be surprised 
also I use an asus a7n8x deluxe (rev 2), which reads the temperature directly from the CPU itself, unlike the kt400 and other chipsets.

Damn...you're scarring me...Really. Guess I have to shut down my computer and buy some fans to get better air flow inside the chassi, I'm sure that's the source of my problem =(

I repete: if you have Abit NF7 or something similar, build on the same platform (as Epox RDA8+ and others) the temp1 in lm_sensors is the thermistor next to CPU, not under. temp2 shows the real temp of CPU.

Ah, if only I could even get lm_sensors to run, but alas - it won't compile against the dev kernel without some legwork I'm too lazy to do. This was from the CPU temp in the bios (a7v8x) as that's the only readout I have available to me right now. It should be noted that the other two athlons in the room are running at 60C and 54C right now. |
