CPU temp at 129C/196F(Err) with a ASUS P2B

[Exiler]

This mobo is now about 3 years old.

Its a ASUS P2B Rev 1.02 Series. CPU (Slot 1 P2 350)
VC: 1.968

Now when I bought it 3 years ago, my knowledge of Cpu, the whole puter knowledge was at about 0%.

Now that I know all about em, and have built my own rig, I have this old puter that always showed me for
CPU Temp in the BIOS as N/A.

I updated my BIOS to the recent one 1012 and still always N/A in BIOS.

I recently found out that for Hardware monitor for CPU there is a 2 pin that needs a jumper, this pin is right beside the AGP port, called "JTCPU" and it had no Jumper on it, so I put a jumper on it, and upon bootup
the CPU temp appeared, but the CPU temp says
129C/196F (Err).

Now I know the Err means its geting the wrong temp reading, so I question is does anyone know why its doing this?

If I enable the JTCPU, I can no longer boot to windows, I get SHARP long continous beep. Because the mobo now thinks the CPU is burning up, if I disable in BIOS it stills screems when trying to boot to windows. I have to remove the jumper to let everything back to normal.

Note, my OS and games run fine, zero freeze and all with the CPU monitor disabled in mobo, so I know the CPU is not that hot. Plus at 129C the CPU would be dead by now and the 196F does not match up, since 129C is 273F.

Any suggestions??

I had the P2b and I have no clue. Just want to let you know this is getting read. I'd guess tho, you mis understood the purpose of the jumper?

It sounds as if that is a thermistor header not jumper.

I agree with LutaWicasa

Thats the exact same thing I thought while reading your post. You need a thermo cable to connect to those pins. It's not for putting a jumper onto.

I put a jumper in there too, when I had p2b. Replaced it with a thermistor quite soon. Pain in the butt, though. Hard to get the thermistor to touch the core of PentiumII without removing the heatspreader.

Allright if what you are syaing is true, and it has to be, then it seems that the ppl I bought it from did not put a thermo cable there and connect it to the CPU.

But then, isint there a easier way? I mean did ALL P2B come like this, they have no CPU monitor unless you put the thermo connector by yourself, its kinda stupid, considering I bought the retail version of the mobo then. Also the mobo MANUAL book also shows CPU temp with no mention of needing to connecting to a thermo cable or anything.

Man last time I EVER let anyone built a puter, good thing I know how to build puter myself now, no more being ripped off by idiots.

The P2B is a really old mobo... Some of the bit newer Abit's have CPU thermal monitoring, but they need a mod for it to work. Really stupid of Asus not to include the thing, as Intel chips have the thermal probe built-in the core.
