An interesting Quirk about this motherboard. The cpu temperature is stuck at 40C in bios AND on the asus probe.

I dont know why it does this and I thought it was just me until I talked to Christoph and he has the same problem.

For me its not a big deal because I'm so overkill with the fans and I have a digital doc 5 for temp control but its a word to the wise out there, be careful.
 
Too late. My CPU temp is 40C too.

Tex, using the other program what is the real CPU temp?

Edit: I've got 3 case fans, the CPU fan, and 2 fans in the Enermax PS. I am not planning on OCing it. Besides, I thought the P4 features clock-throttling? If it gets too hot, it slows it down or shuts off the computer.
 
Worry not my bretherin 🙂 Will be fixed shortly in bios update...actual temp confirmed by Tex's digital doc is around 30c...
 
30C = I'm not worried. 40C was fine.

I haven't done much with it all: just intalled the cpu, hsf, ram, mobo, videocard, floppy, and harddrive. I've booted it up to make adjustments to the BIOS and even ran a memory test to test the Crucial DIMM. It all works fine so far. I'll start backing up stuff on my current box tonight and hopefully install Win2K and everything else on Saturday.

Good to know it will be fixed soon. I've been considering this board. 30c, damn that's coool 🙂 Is that with stock intel cooling?

Not, it's with stock airplane reactor cooling... (from the pics I saw) 😉


And Asus are usually quick to fix those things.

hehe, I love it...Tex's cooler is cutting edge... I can't wait till they come out with 'Nuclear Sub-Reactor Cooling' fpr the pc 😛

hahaha what can I say, I lika mah fans! 😀


 
I doubt software will display temps that are any different from what is displayed in the BIOS. They both use the same onboard sensors. It is possible, but unlikely.
 


<< Worry not my bretherin. Will be fixed shortly in bios update >>

When?

Can someone confirm that this is a BIOS issue, not a hardware problem!
 


<< The cpu temperature is stuck at 40C in bios AND on the asus probe. >>

Just completed installing the P4B266-C with 1002 BIOS. Same problem. Anyone has any update on this issue.

BTW, the P4B266-C is a wonderful overclocker. It runs a 0.18 micron, 1.5G P-4 at 1.86GHz (15x 124 FSB) and stable.🙂
 
I downloaded MBM5 (Motherboard Monitor 5) and it reports the CPU temp just fine. I'm at 41C right now. It's been as low as 38C and as high as 46C. I'm running a P4 2.0A @ 2.0Ghz on a P4B266.

Edit: Once you've downloaded and installed the program, simply go to the "Temperatures" settings and set the CPU sensor to ASUS 2 (CUSL2).
 
I don't believe that MBM 5.x recognize the Asus P4B266 yet.

It is true that the MBM reading will go up and down when I run a torture program and stop, such as the Prime95. However, the range of readings are always the same when I change CPU, vcore voltage and heat sink.

Anyone heard from Asus about this issue yet?
 
Another issue: the onboard sound is CRAP. well, at least with me anyway. If I tried to enable it I got a hard lockup at the windows startup sound. The ONLY way I could get it to work was to remove every PCI card in my system. I then tried an Intel NIC in each slot. Every time it resulted in a hard lock. Remove all PCI cards --> sound works again. Very frustrating.

(This is on Windows XP by the way.)
 
my temps are stuck at 40C as well
however i installed mobo monitor and idles temps are around 30~32C and full load is about ~41 and this does not change when overclocking so i'm a little leery about saying this is accurate but it's better than straight 40s 😉
