another CPU overheating ?

[rezzij]

Am running:
MB = gigabyte 7VT600-RZ(-C)
CPU = AMD 2200XP+
AGP = eVGA mx 440 64meg
RAM = (2) 256meg 2700
OS = xp pro
CPU is running AMD stock fan ...

After having many unrelated problems, I replaced my motherboard and am now suffering random BSODs (3-4 a day?) .... after one, I check temps in BIOS and am finding case temp 39-40c and CPU temp 69-70c ... too hot ?

most common error is IRQL_NOT_EQUAL_OR_LESS_TO, with a few PAGE_FAULT errors ...

thanks in advance ...

If i'm not mistaken that is a driver issue. Have you recently installed any new drivers or updated any?
Installed any program that uses certain hardware?
That would be the first place to look. Uninstall and see if things are ok. Then look around for other drivers or prog if you find the culprit.

Next step might be to disable pci cards one at a time and see if you can find it that way. Then go on from there.

run memtest on your ram. YOu can get that free via google.

Actually, i dont think thats too hot, but on the hot side but for an amd not too bad.
You could always take cpu off and apply fresh thermal paste and re-install. Make sure you install fan wiring!

rezzij,

CPU temp 69-70c is a little on the hot side.
My experince with that cpu with stock heatsink/fan was usually 49C-59C.

Check that the heatsink/fan is mounted properly.
I would also recommend removing the thermal pad from the heatsink and apply a small amount of thermal paste (about the size of a grain of rice) to the raised portion of the cpu. Arctic Silver III works well. Make certain that the heatsink is fitted correctly and not on backwards. Don't even think about powering on the PC with out the cpu heatsink/fan attached or you will fry the cpu.

Also, below 50c is an ideal temp.

To Hot!
This is only a Thorougbred or Thornton core XP2.2+ so isn't a particularly hot CPU as it was the lowest clock speed on that core.
Obviously much depends on climate "how warm an enviroment the PC is operating in" but typically an XP2.2+ will idle in the mid 40's Centigrade with maximums around the 50C mark.

Anything under 60C is considered safe and stable.

AMD XP's start to get flakey in the mid 60's C so 70C could definately be causing you problems.

Have you fitted at least one extra case fan?

Have you fitted the heatsink the correct way around? recess in the base of the heatsink must be positioned so it is mounted over the raised cam box on the CPU socket.

Using the original retail grey pad is fine but if you have remove the heatsink this must be completely cleaned off and thermal paste applied to the small raised core of the CPU (about 1 to 2 rice grains in vulume)

Make sure the heatsink is not blocked and the fan is spinning freely.

well, I checked several things ... heat sink is mounted ok ...
no new cards, software, anything but the new motherboard ...
after first couple of blue screens, I Added a new hard drive and took out two other ones, blue screens continued as before ...
ran MemTest-86 v3.2 with some erratic results ... it had one tiny error in the whole first pass ... it then ran 4 consecutive passes flawlessly ... the 6th pass, which was around 3 hours later, it started getting errors every few seconds ... I checked CPU temp - and it was 73degrees C ....
so, I think I might have to look into some serious heat reduction units ...
thanks to all for help

Replacing the motherboard surely involved removal of the heat sink in order to gain access to the CPU. This being the case, a stock AMD uses a thermal pad on the heatsink that MUST be replaced whenever the heatsink is removed. They cannot be reused as the phasing material will not reflow over the CPU, therefore leaving gaps between the CPU and heatsink, which allows build up of heat.

Having said all that, did you clean the heatsink and CPU of phasing material, then either apply a new pad or some thermal grease?

 

[rezzij]

I did apply some new heat grease - am sure not the highest quality as I forgot to get it that day when I got the board, so had to stop at Radio Shaft later and pick up some ...
I am not sure on the quantity, so will open it again and apply more.
thanks

The quality of it is less important than how you put it on. Long as its put on right then you should be ok.
