K7N2G-L and cpu overheating

hi there,
i'm hoping you guys will know the answer to this...
i'm having problems with a new athlon 2800xp chip and overheating
my old 800 athlon ran at around 39° max, the new 2800xp idles in the high
40's but under load keeps going up and up until it gets to about 65° then
everything locks up soon after...
i just bought the biggest hsf i could find (for an athlon 3400) but the
problem is not much better...
i have to run the chip at 100 bus speed it runs cool enough not to lock
up...
is it possible the cpu could be faulty ? i can't think of any other
explanation

i'm using the proper paste and the case has plenty of ventilation etc. - the
hsf is definitely installed correctly, you can feel it getting too hot to
touch as it heads towards 70° - bios is the latest version etc.
it does report the m/b temp at 38° (even with the case off on a cold day)
which seems quite high but i don't think this is the problem

also mbprobe ( http://mbprobe.livewiredev.com ) gives warnings that vccp1
and vccp2 are 1.65v instead of 1.80v... in the bios i can set this voltage
manually - at the moment it is set to "by h/w" - should i change it in the
bios to 1.8v ?
i can't for the life of me find what it should be for this chip on the amd
site !

thanks if anyone can help, this is driving me nuts !

The proper cpu voltage should be 1.65v, id try putting some extra case fans
in your system to improve air flow, your system temp is high to in my system
the case temp is 29-30 degrees and my cpu overclocked is to 2300mhz never
more than 50 degrees using stock amd heatsink & fan.

Remove the hs/f assembly and check that the chip is actually in contact
with the copper core, and not the aluminum base. I found out it is easy to
install the hs/f the wrong way, and it'll run but hot, and when pushed my
temps got into the 70's. Bought some AS5 to help and found this out when I
removed the hs/f. Now it gets to 44C max o/c under severe load. Might sound
obvious, but I got nailed on this one with a new Vantech.

thanks stuart, i don't think the hs/f is the problem though... it's been on
and off and checked (tried different hsf's too) a dozen times now... even
the hsf i bought for an athlon 3400 gets too hot to touch and can't keep the
2800xp below 70° under load...
i just tried a 2200xp (allegedly reknowned for running hot?) and it runs 20°
cooler, i can't get it over 50° which sounds much more 'normal' to me
i guess i should take the 2800xp back ???
i was just hoping someone might have a miracle answer or a 2800xp of their
own to compare temps

thanks,
andy

hi doughnut,
that did the trick, many thanks !
i didn't think it was going to help much but i cut a hole in the side panel
for another fan opposite the cpu and that's brought everything down by about
10°
many thanks !
andy

If the heatsink is getting hot thats good as the heat is being transferred
okay. What is the make and model of the heatsink and fan. A large copper
insert or all copper ones are best with lots of thin fins rather than
thicker fins.

My TT Volcano 11+ runs at 1200 rpm (17dB) and cools a Barton 2500+ O/C to
2.2 GHz to about 50 deg C under load. This HSF is rated to XP3400+

hi peter,
yes that's what i thought - i have this hsf
http://www.arctic-cooling.com/en/
it seems able to dissipate the heat a little better than the stock one was
i posted earlier that the problem was fixed by cutting another fan into the
casing side panel opposite the cpu -
but whilst it's much better than before it will still creep up hot enough to
lock up during a 3dmark2003 benchtest - it idles at 40° cpu and 34° m/b now
but makes almost 70° cpu and 45° m/b about 10 minutes into 3dmark2003 and
then locks up... this is even with the side panel off and a large desktop
fan helping things along...
not quite sure what to try next unless i buy another cpu to see if that is
the problem...
any ideas ?
thanks, andy

well seeing as you asked so nicely and my camera is to hand...

The HSF looks suitable, I have read various reviews on it and it seems to
perform okay. The 29 CFM rating seems good enough. What voltage do you run
the chip at. I think that your should run at 1.60 volts. Higher voltages
will make the CPU run much hotter.

At 70 deg C the HSF would be way to hot to touch, not even for a second.
The CPU is in danger at this point of being fried so be careful!

The lockups do seem to be caused by the CPU overheating, if the voltage of
the CPU is at stock speeds check that the frequency is correct. A XP2800+
(333 FSB Barton Core) should run with a 166 FSB which is set on the BIOS.
