Linux, overclocking and heat

purrkur · Post by **purrkur** » Wed Apr 28, 2004 2:57 pm

I was wondering if you guys could give me some feedback...

I am running an unmodified BP6 (standard caps and all) from 1998 with two 400MHz Celerons in it, at 466MHz. The BIOS is the latest one from Abit. I am running Linux (Debian), now with the latest 2.6.5 kernel and it is simply rock solid and stable. The system is on 24/7 and I do make it work hard (as an Enemy Territory server amongst other things). It has not crashed once on me.

Anyhow, after overclocking it and compiling the 2.6.5 kernel I installed support for I2C and got sensors working. I just want to get some feedback on the values that I am getting:

Code: Select all

vid:      +2.000 V
alarms:

          Sound alarm disabled

The CPU's were idle and had been idle for some time when I ran sensors...

What I would like is to get some feedback on the temperatures. Temp1 and 2 are the cpu's while the third is the system. High? Low? Justabout right? Anybody know where the system temp is measured?? I am a bit surprised by that one because my harddrive temp is much lower than that:

Code: Select all

[davidt@loki]:~$ hddtemp /dev/hda
/dev/hda: ST340014A: 34 C

Could you also give me feedback on the voltage values. I got a 340W power supply that is very decent, but the motherboard still has original caps as well as the faulty EC10 (I think it is called). A project for this summer is to buy new caps and replace the ones I got.

Third thing is the fan values. Is it possible to get readings lower than 3000rpm?

the temperatures you get are OK, the voltages also. the CPU 2 voltage there with your settings you get VTT voltage, to get core2 voltage you need to change the settings, though I do not know how it is in linux.

with the fan you probably just do not get the readings.

...what he said about voltage on cpu2.

Temps are in line with my BP6 but ive been told that the SYSTEM temp should be lower then the cpus. I changed some of the caps on my board and my system temp dropped a bunch. Before the surgery the system temp was 75C after the cap change it is more like 50C but always hotter then the CPUs.
Derek or hyperspace, Inactivex, anybody else got info on SYSTEM temp in comparision to CPU temps?

purrker,
You can probably set your voltage down on the CPUs in the BIOS to 1.85 or so and still run rock solid.

I think the sensors on the bp6 are miscalbrated, so are many others motherboards
I just got a reliable thermal probe, stuck it in there, and then just nudged the numbers on my onboard sensors via software.
All 3 of my sensors are just a couple degrees off

24seven · Post by **24seven** » Thu Apr 29, 2004 4:19 am

You need to edit /etc/sensors.conf to change the settings, I have (tried to) attached an example one.

I also found this:-
http://freshmeat.net/projects/wmbp6/

wmbp6 is a DockApp monitoring sensors (temperatures and fans speed) of
an Abit BP6 mother board. It use lm_sensors 2.3.0 or newer (untested).
Double-click on wmbp6 launch BP6mon, a more detailed monitor.

Thanks everybody for the feedback! This goes to show that the BP6 enthusiast community is alive and kicking

24seven, thanks for the config. I'll give this a go as soon as I have the time!

My system temp is normaly hotter than my cpus.

24Seven,

I have been checking the config files that I got on my machine and the one you sent. It is very possible that my config is a bit more upated than yours. I found this in mine that you don't seem to have in yours:

Code: Select all

# Abit BP6 motherboard has a few differences. VCore1 and VCore2 are the core
# voltages of the two processors. Vtt is memory bus termination resistors
# voltage.
#    label in1 "Vtt"
#    label in8 "VCore2"

However, the above was in the section for these chips:

Code: Select all

chip "w83782d-*" "w83627hf-*"

I am certain that my board is using the w83781d chip and not the above. Any comments?

I am using version 2.8.6 of lm-sensors from Debian. I can post the whole config if you want. I found no differences other than the above and since they are uncommented they don't matter anyway.

davd_bob · Post by **davd_bob** » Thu Apr 29, 2004 11:27 am

Thanks 24' for the response. I checked my temps today(Im running a single 366 at 66fsb until i get a pair from kuun) and systemp is just 1-3degrees higher then cpu2.

I got the current ver of MBM linked on this site. It reports some of the wrong voltage like core2 and VTT. I was informed that an older ver works correctly but I couldnt seem to find that ver.
can someone tell how to setup the MBM correctly or give a link to any monitor that reports correctly?

Guess im not as smart as i think i am.(everyone already knew that though)

purrkur: That config file was one I found on the internet while at work. I’ve only just reinstalled Linux and haven’t finished setting it all up yet. But mine is defiantly using the w83782d chip.

Like I said it hasn’t been setup properly yet, but here is a dump from mine.
david_bob: As you can see from the dump my system runs roughly 10deg hotter when under load.

24seven: Strange. Sensors-detect told me I had a w83781d and that is what I set up as a module when building my kernel. I can see it when I use lsmod too and everything is working fine. However, when I run "sensors" I get this...

Code: Select all

w83782d-i2c-0-2d
Adapter: SMBus PIIX4 adapter at 5000
VCore 1:   +2.02 V  (min =  +1.90 V, max =  +2.10 V)
..........

That is exactly what you are getting. What is the deal here? I guess I need to unplug and open my machine to really find out....

what Celerons are you using?

24seven · Post by **24seven** » Thu Apr 29, 2004 4:20 pm

Dual 500's no overclocking at the moment.
Intel P3 heatsinks and fans one case fan, so its not too hot really.

Version 4.18 showed the correct VCORE2 values. I think I still have it if you are interested.

Here's my read out:

System temperature is always higher on my system. It would probably run closer to the CPU temperatures if I had a fan blowing directly at RT3 on the mainboard.

Oh, yeah. My signature shows a picture of RT3 (System) on the mainboard.

Here's a better one:

my sq-2, bp6 dual 533 std
runs win2k
mbm shows 39 39 and 43 for temps
my other board with those huge block copper coolers ran cooler, about 34-35, down from 45 on std coolers.

YES please hook me up.

It might be a kinda big attachment but im willing to try receive it if you will email it to me.

Kan du förklara för mig hur du fick sensors att fungera? Alltså hur du fick in i2c och så att den hittade dina sensorer. har du msn kan du adda mig där om du vill.
