4PDA2+ Erratic temp and voltage readings

Dave,
I received this board only 2 days ago. I'm not sure I want to live
with such a defect on a brand new board. Thanks for your input.

The CPU temp on my 4PDA2+ occasionally also jumps high for one reading (also
with MBM under WinXP). And it's been like that ever since I got it half a
year ago. I wouldn't worry about it.
Voltage is also bouncing just a little, but note that while displayed in
0.01V steps, the sensors' resolution is coarser.

Andreas,
Your system observations are roughly consistent with mine, which is
reassuring.

I am wondering about another potential problem. CPU temp observed in
PC Health immediately after stone-cold start-up hovers around 33/91,
jumps to 38/100 on occasion, but generally remains constant at
~33/91(no-load condition, just sitting in BIOS). Ambient temp is ~ 68
deg F in this room.

This is puzzling because I thought the sensor diode feeding the PC
health CPU function is actually detecting CPU socket temp and not core
temp. Either that PC health CPU temp is actually core temp, which I
understand rises almost instantaneously, or displayed CPU temps are
way too high.

System temp starts at ~22/68 and rises to a no load value of ~29/84,
which strikes me as being correct. Thanks for your help.
Dave

That's the case with Athlons and earlier Intel chips, but the P4 (and
Athlon64, AFAIK) has indeed a thermal diode built in the core.

Ah--Did not know that.

Are you using a variable RPM fan that adjusts to temp? Could it be its
spinning up and down is effecting the temp you see?<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: 4PDA2+ Erratic temp and voltage readings 

Mine's an Antec too. I don't think it matters though because the last board
in this case didn't jump at all ( Soltek AMD). Still mine will occasionally
shows quick jumps up to the 60s or so(very quick, just a sec). The Antecs do
have an rmp sensor for the PSU and 2 fan only connectors that run the case
fans at lower voltage. Would this contribute? Is this board's sensors that
touchy? What other set ups mention this problem? I can't remember the forum
I got the initial heads up about this, but I do recall it was not an
isolated incident. Did the original versions have this problem or is it only
on the rev 2s? Any way mine's a rock, though it would be nice to be able to
rely on those readings. I mean are the temps actually real or just ghosts.

4PD23815 my board is rev2 and it happens regardless of which settings I use.
I haven't
tried 4PD24319 yet as I just became aware of this release. I'm loath to
flash a new bios if it doesn't fix any major shortcomings. Can you tell if
this update addresses this particular problem? It just says:

Vcore value selection will be disable when Prescott CPU is installed.
Updated Prescott CPU micro code. Solved 16x4 memory can not boot (Error post
code is "E6"). Modified system memory type string with Epox Standard ruler.
Added "E" designator to identified 90 nanometers processor with 1MB L2
cache.

While this will ready my board for the latest P4s does it do anything else?
Otherwise I'll wait to flash this until or if I decide to upgrade my cpu.

I've had the same ghost thermal spike problems since day one with this board
(november 2003), and in an attempt to resolve the problem, flashed to the
latest bios of 3/19/2004. Immediately on boot, my SATA RAID was not
correctly detected, and the raid bios utility wouldn't recognize one disk.

I've flashed back to the 8/15/2003 bios, and still get an error reading for
the disk during the SATA initilaization, but the system runs fine.<!-- ~MESSAGE_AFTER~ -->
