E8400 Temperature Problem

shenry · 02-15-2008, 06:19 AM

I recently got my E8400 and a new mobo(P35-DS3). So I took out the ol' 4600+ x2 and the mobo and put the new stuff in. Connected it and all that. So I boot it up into the bios and go looking around for anything that needs changing. I see that my CPU temp is 105 degrees! YIKES! I thought. So I shut it down straight away. took the panel of the case off touched the heatsink and its colder than room temperature.I googled it and I see numerous people with my problem.I booted it up again into windows uninstalled the AMD drivers and installed the new ones, thinking alot of people are having this problem so I kept going.The next day I got home from school and boot it up seems a little slower than my athlon.I updated the bios to the latest one. I played COD4 and sure enough around 2-4 mins in my computer shuts down. I turned it on and went into the bios 115 degrees! Around five seconds later it shutdown again. So I waited till it cooled down. I ran coretemps and found that it was only running at 2 Ghz. But windows says different (3 Ghz).

So does any body know a work around for this? Has intel released anything? I haven't found anything yet. This is my first intel expierence and I am a bit disappointed right now.

I havent overclocked it at all or used a third party heat sink so my warrenty should cover it right?

Also I'm thinking I should disable the thermal settings so it doesn't underclock it anymore.

Alot of us are having this problem, but your temps seem... crazy off..

What heatsink are you using, stock? sure its seated correctly?

its possible that IF it is reporting the temps wrong that the bios reads its at the "max" temp and then decides to shut the computer down.

I beleive there is an option in bios to disable that.

about the 2ghz, its downclocking. To make that stop, disable C1E and EIST

I tried that but it still randomly shuts off and wont even boot with those settings you recommended. It can only boot at 2.0 Ghz.So far.

assuming you properly applied thermal paste (not using the dry stuff pre applied by intel) and seated the heat sink push pins properly (check to see all 4 push pins went through the mobo) then i'm guessing the temperature probe on the motherboard may be broken.

You may need to make sure its making correct contact to the cpu

I RMA'd my E8400 due to a similar problem. Newegg tried to charge me a restocking fee but I bitched at them and got it waived.

Mine was the core temps though. If I understand correctly, the core temps are the sensors in the processor and the processor temp is the sensor in the motherboard.

If you're positive the heatsink is on properly and your temps are not actually 100+C, I'd RMA the motherboard for sure.

Personally, I'd RMA the processor with it, but that's just me.

And, how did you put the paste on it?

dznutz · 02-15-2008, 08:45 AM

the cpu core temps is also a good reason. got a spare cpu lying around? try using it to rule out the cpu or mobo

shenry · 02-15-2008, 09:02 AM

I'm using the stock heatsink and the pre applied paste for know, I know its probably the worst (with the exception of no heatsink!

) but I still would have thought that it would boot at the advertised specs...

I'll probably RMA the CPU tomorrow when I have time. Do you really think I should RMA the motherboard too?

I really don't see why anything like this should happen, wouldn't they have tested them before they released them?

dznutz · 02-15-2008, 09:19 AM

you're using the pre-applied goop. don't you have any thermal paste?
have you removed the mobo to see if all 4 push pins are through?

before rma-ing anything i'd rule out the simple things first unless you like playing guessing games
