Hi all,

Brand new to the forum - Looks like a great place!

I'm working with an old backup computer

Conroe 945gdvi

e6700 stock on air (freezer pro 7)

4 x 1gb 

old 250watt psu (about to switch out to 550 for testing

60gb OCZ SSD

GTX680 2gb (I know I know...lol)

 

This box has been something of a test box on and off for years. I do a lot of computer work and repairs so it's handy to have a spare.

Recently it began shutting down after a few minutes of use - Full, no warning, shutdown.

 

I didn't pay it much attention because I'd recently reinstalled windows and assumed some typical windows malfunction...fix it later, that sort of thing.

Anyway, now I'm setting up a test environment for a rust server and have learned that the CPU is overheating from 45 ish idle (bios and openhardwaremonitor), to 90+ under load (openhardwaremonitor)!

 

I learned that if I remove two of the sticks of RAM, specifically from slots 1+2, the temperatures drop substantially, but still not to what I'd want. Maybe 65-70 under load?

I've juggled the sticks and am not convinced that the ram has failed. My suspicion leans towards the board itself.

 

Rule out the basics. Airflow is good, there is not dust to speak of.
Cooler is Arctic Freezer Pro 7, new thermal paste..Good clean connection.

 

Today I ran memtest with 4 sticks installed. I didn't let it finish as the Core temps were constantly riding 90 degrees, but It showed no errors in about 15% completion of full memory test.

Not much of a test, I know, but if the memory was causing instant overheat, I'd like to think it'd show errors under test straight away.

 

Anyway, it's not life or death but I usually fix my own PC problems, right down to board recaps/biso flashes, etc. I don't like being stumped! :P

 

Many thanks in advance.

250W PSU and a GTX 680? that might be your problem right there...

Hi,

Thanks for the reply.

I've been running today with the 550 watt with no change.

 

Still, is it logical that under powering the machine would cause CPU overheat and no other issues?

There may have been other issues. I wonder, however, if the issue was that the CPU fan wasn't receiving enough power.

Thanks for the suggestion but I'm afraid it was full tilt.

I have it set to come on early and fast, and it's definitely working top speed.

Gonna give ubuntu a spin tomorrow and rule out software.

Will post back results.

While its rare to have an Intel CPU fail; with an E6700 running about $10, I'd replace it. Many years ago, I had the metal lid fall off a P4 and nothing I tried would get it to where it didn't overheat in about 5 minutes......

Hi Davis,

Yeah, I know what you mean, although I had the same advice from other people regarding ram and motherboard.

Heh. £60 would get my a q9550, board and ram so, for now, I'm going to avoid spending anything on it.

 

Just testing under ubuntu. Same temperatures, so obviously not a software issue.

 

Next step, remove CPU + RAM and give everything a damn good clean with contact cleaner.

And you pay yourself 50 cents (US) an hour?

What country are you in?

Please avoid insulting our members... there are plenty of reasons to be frugal and it doesn't hurt to try alternatives

Thank you, Scath.

That's an insult? I don't even understand it.

I'm in UK.

 

My point was I could replace the whole machine with a quad core for pittance, or literally pick up something better from the local amenity site.

I'm interested to know and understand the reason for the problem.

 

I could have blindly replaced parts without advice from a forum. ;)

I'm sorry, I wasn't trying to be insulting; but, rather, as efficient as possible and replacing the system board seems like a lot of work plus a lot of money just because a $10 CPU is failing. Heck, I have an old Dell E520 with an E6600 that I use very day.
BTW, Windows 7 only natively uses two of the cores and whatever else is there just twiddles its thumbs (I have seen it personally).
It would be nice if the chipset supported a 1333MHz front side bus; but, .....

Hi,

Ok, thank you for the response.

I appreciate your posts but really this machine is adequate for the simple tasks it has to do. It doesn't need to be more powerful.

I have an i7 laptop and 12 core xeon desktop which do my real work.

 

IDK...If replacing the CPU solved the issue I'd know it was faulty and that'd be about as much as there is to learn, but if it doesn't I don't want to start down the replacing/guessing road.

I know my luck...I'd end up replacing the whole damn thing bit by bit. :facepalm:

 

Thanks for all the replies, chaps.

 

PS: I think might have an old P4 3.0ghz in a cupboard somewhere. If i can find it I'll swap the CPU out and report back.

Hey Davis, you got me thinking...

I've delidded CPUs before (intentionally). Any that I did had the top plate soldered down.

Out of of interest i pushed a plectrum under the outer glue -VERY gently, of course.

 

I mean, what do I stand to lose..£5, as you pointed out. ;)

 

Anyway, the top plate just fell straight off with nearly no pressure. Looks like it was only held down by the glue and the actual heat contact was made with thermal paste.

Maybe that's how they did it on c2d chips? I'm tempted to solder it down just out of curiosity.

 

The chip runs and works flawlessly, but overheats. I'm thinking this makes a lot of sense.
