Hi, I´ve a A7N8X-E deluxe MB, 2x 512 MB Infineon 400MHz DDR RAM and an
Athlon 2800+ that is cooled by an Artic Copper Silent 2. Systems runs
stbale at 100, 133 but not at 166MHz external CPU speed. I´ve changed the
RAM with that from my office-PC but the problme is the same. Let me mention
the additional problem: direct after switching the PC on a, I hear the
accustical warning "CPU FAN FAILED", but I´ve conncetd to the right positon
(CPU FAN 1 on the Mainboard. The temperature in the BIOS displays a
temperature of 60°C at 166 MHz and 56°C at 133 MHz external CPU speed. Is
this too hot for the CPU ?

Does anybody have simliar problems ? Is this a problem of the MB or the CPU
or the CPU FAN ???

Thanks for your help,

Ellerich.

You running that ram in sync and not out of sync with the cpu?
The XP2800 runs at 333MHz(166x2)
Ram should be at 166 as well.
The cpu fsb jumper should be set to fsb400/333/266 setting and not fsb200.

If the BIOS memory frequency setting is "By SPD", the ram will run
at its rated speed. In this case, that is DDR400.

You want the memory to run at the same speed as the FSB of the processor.
A memory setting of "Sync" or "100%" means the FSB and memory run
at the same speed.

HTH,
Paul

CPU FSB jumperseetings are the default: FSB 400/333/266....

The frequency setting ist not " BY SPD"...........its "Auto"....., but I
think the main problem is the high CPU temperature of 60°C (and the CPU FAN
failure message) or don´t you think so ???

Well, 60C is warm, but it doesn't mean that it has to stop working
at that temperature. 65C is a reasonable limit.

Is this temperature measured while idle and sitting in Windows ?
Or is this temperature at 100% load ? If the CPU is 60C at idle,
it'll be a lot more under load.

Your HSF is here:
http://www.arctic-cooling.com/en/

Rated Fan Speed: 2200 RPM
Power Consumption: 12 V, 0.13 Amp.
Air Flow: 29 CFM
Weight: 395 g
Noise Level: 18 dB
Thermal Resistance:   0.30 °C / Watt
recommended CPUs: AMD Athlon XP up to 3200+

Make sure Qfan is disabled. You need the fan to spin at its top speed.
I would have thought the 2200 RPM is enough for the monitor to measure.
The AthlonXP 2800+ operates at 1.65V and draws 53.7watts. If the
room temperature is 25C and the case (motherboard) temp is 30C,
then the CPU will be 30C+(53.7W*0.30C/W)=46.1C at 100% load.

This means either you are measuring the die temperature, or
there is something wrong with the way the HSF is installed,
or Vcore has been set higher than 1.65V or you have
overclocked the processor some how. Check to see that the
BIOS detects the core clock as 2083MHz.

Have you cracked any slivers of silicon off the CPU die, while
installing the heatsink ? It could be that the CPU is
damaged or something. Have you ever run Prime95 torture
test, and is the processor stable with 100 and 133MHz clock
when running Prime95 ? (no roundoff errors.) Can you run
the CPU in another motherboard, to see if this is a motherboard
issue ?

HTH,
Paul

....damn...same problem as before....
after 35 minutes of Prime 95 torture-test I stopped the test to ensure that
the FSB ist at 166Mhz....it was, but after restart I´ve had the same
problems again....

however

I think the problem is not due to the temperature because it increased up to
69°C/42°C (measured by ASUS PC Probe), the FAN runs at 3000rpm and system is
stable running without any errors (at the moment)

I think there is a hardware defect......what do you think ???
