Help with new PC

 

PC:

CPU: C2D e6850
RAM: 2xDDR2 800 corsair twin 6400 (5-6-6-15 i think)
MB: Asus Commando (updated bios)
COOLER: Thermaltake Big Typhoon VX
PSU: Fortron 400W
GPU Gainward 8800 GT 512
Well ventilated case with sound isolation (foam).

I'm getting huge headaches with this machine. Just installed it and
allready it's overheating (according to Everest) with around 70C at full
load. I can't figure out what's wrong. I'm planning to OC it, but for
now I just can't figure out why it's running so hot? On the other hand,
mesuring with TAT gives a max temp of only 50C. So what gives? which one
of these should I trust?
Tried a few tweak as far as overclocking is concerned but I'm a noob
when it comes to OC-ing intel. So far I think the ram is the weak link.
CPU can easily go as high as 3.6-4GHz, but testing ram with memtest
reveals tons of errors..

..sorry for the chaotic mature of the post but i've been working on this
for the better part of the day and i'm completely lost with this new PC
and can't seem to figure out what's wrong.
Any temerature or overclocking suggestions are apreciated.

The temperatures shown in the BIOS are of limited value.  When you boot into
the BIOS, four conditions exist:
#1.  The system has just been started, so the CPU temperature will be lower
than normal
#2.  The CPU will be under minimal load, so the temperature will not reflect
normal operating conditions, much less a heavy processor load
#3.  The operating system will not be loaded, so the idle function
implemented by Windows 2000/XP/Vista will not be used
#4.  Any fan and CPU speed stepping you have set in the operating system
will not be operative.

In short, about the only use of BIOS temperatures are to tell if a heatsink
has fallen off.

A reboot gets you the temperature at idle which gives you something to
compare to the idle temp when the OS is running. The OP's problem is that
he has two programs that give temps that are 20C apart. Comparing idle
temp to idle temp will allow him to figure out which program is right.

No, since the conditions are different, as I point out #1, #2, #3.

And no, since the location of the thermal diodes that TAT use are not the
same as that used by some other CPU sensor reading applets.

And no, since the temperature rise will be greater for TAT as heat
production increases compared to the rise in some other CPU sensor reading
applets.

The Intel description of how TAT operates is a good source for understanding
the differences.
