Prescott's Roasting On An Open Fire
Roughly 3-4 days ago, I setup my Intel Purchase Program (IPP) system as another dedicated SETI Cruncher.
Now, this was my first venture into LGA 775 country, and as such have never installed a heatsink on that platform. Using AS5 and the edge of a business card, I carefully smeared the festive silver goo around the CPU heat spreader.
The system gets together, and I boot into the BIOS to check the system temperatures (both CPU & the "Thermal Zones"). All is normal (CPU @ 54*C Idle, System Temps are 27*C and 29*C).
I install WinXP Pro SP2 and get the system crunching SETI. Figured it was time to overclock slightly (damned Intel boards only let you go 4% above nominal). I crank it up from 3400 MHz to 3600 MHz (roughly), reboot and check the BIOS for temps again. The surprise I got is below.
I cracked open the case and check for airflow and heatsink temperature, but no changes occured. I'm thinking it's either a screwed up BIOS or else the board's sensors are ****ed, because this is what I found:
HOLY (#*&$(*&, I knew Prescott's ran hot, but holy crap.

Btw is zone 2 outside of your house by anychance
Anything over 90C isnt possable on a presscott unless the throttleback on the chip is somehow defective or the cooler removed
Btw I just remembered this now intel said something about there boards temps showing up wrong in there tool and there bios for there socket T boards. If thats a offical intel board that could be why.They said they were working on a solution.
I remember seeing a link on toms hardware i shall try to find it again and post if i do
I flashed the latest BIOS onto the board (0022 - whatever that means) and it hasn't helped at all. Still the same readings.
The funny thing? Zone 1 & Zone 2 are right next to eachother on the board.
I've got room temp @ roughly 15*C right now (open window in the dead of winter), so at least one of those sensors are close to right
//Edit: @ GrayFox: Nice shiny new A64 you have there
Did you hook a vaccum clean to it for airflow???
is the sensor touching the heater itself... errr is it touching the processor...??
FUHHY thing is that if the thing is OC'd MAYBE you are getting processor and zone one tossed high, and CPU fan. Only things I can think of to check, is one each of a calibrated thermal probe and calbrated laser RPM meter to check fan speed.
Wierd.
Just another reason to hate Intel boards. You can't even clear the damned CMOS on this board. The jumper is physically missing.
As for the 9000 RPM fan, there is no such beast installed in that system. It's just the regular Intel Boxed Prescott Cooler & default fan, which spins I think @ 3100 RPM.
