Duron 1.2 Heat Problem?

[tkistre]

I have built about 7-8 systems using the Gigabyte GA-7VKML (integrated motherboard V/S/L), Duron 1.2, 7200rpm 20 gig hard drive and a generic Mini/Mid Tower. All of the systems run stable with no problems. The last one (my brother's office PC) I built runs great too, but it has a heat problem. The cpu temp (in BIOS) states it was running about 163 F/73 C. The system temp is high too, around 130 F/54 C. The case side you open for installation is hot to touch. I added a 80mm fan in front of case and put a larger heatsink (good for a Athlon XP up to 2000+) on the cpu. The temps came down a few degrees to 153 F/62C for cpu and 125 F/52 C for system. I felt this was still too high. I called AMD Support and even though the guy agreed it was high, he said as long as the system runs stable, don't worry about it. The only suggestion he had was to make sure the motherboard wasn't supplying too much voltage. I got the code off the cpu and according to AMD's tech sheet, this Duron should have 1.75v. The motherboard in the BIOS showed to be supplying about 1.77v. The motherboard autodetects setting and there is no way to manually change it. Like I said, the system has run flawless for about 1 1/2- 2 months now, but that heat problem is really bothering me.


Does anyone think that .02volts would make the processor run that hot?

it really shouldn't be running that hot!! maybe your motherboard is reporting the wrong temperatures..

but you can try to lower the voltage.. also check the I/O voltage.. should be around 3.3
and for the core voltage, you might be able to bring it down to around 1.65 since you're not overclocking..

I don't have direct access to the PC, but I'll check the I/O voltage next time I'm there. I was going to try and bring down the core voltage, but that's the problem. The motherboard will not let you manually change it. Well, at least not go down. It will allow you to add .5% or 1%, but not subtract.

But does anyone think that the extra .02volts is really making it run that hot?

BUMP Please

Ok listen up. I also have a 1Ghz Duron and my temps are (as we speak) 46C for the CPU and 28C for the motherboard, with my case being open. Of course, i dont have a very strong heatsink thats why my temps are at that point. Still though, the system works flawlessly day and night. My voltage Core right now is 1.79V eventhough in the BIOS it says 1.75. This is normal though and it shouldnt worry you. Vcore voltage always fluctuates like this.

My guess us that you havent installed your HSF correctly on your CPU. Even if the clip is secured, the HSF could be in a wrong position. Doublecheck it, re-apply thermal compound and ask again if you still have problems.

Definately reinstall the heatsink, make sure the fan is working at full speed.

No problems with the heatsink install. I've been building systems for 5 years now (not that I couldn't have made a mistake) and I am very cautious about installing heatsinks, especially on AMD processors. The original heatsink was installed correctly. When I added the larger heatsink, I also put Artic Silver compound. I have doubled checked it and it is only correctly. I don't remember the rpm's the fan was turning but I'm sure it is running efficient.

Like I said, the system runs flawless. I was just concerned about the heat. Do you think adding one of those fans that take up a PCI slot are good? I have never used one before. The case is not set up to add a 80mm fan in back. The Card slot type would be the only one to work.

Thanks for replies fellas. Any ideas are certainly appreciated!

Put the system under load and reach in and touch the base of the heatsink. Slighty warm is in the 40-45C range, real warm is in the 50-55C range, and too hot to touch is 60C or more. Maybe the motherboard temp readings are inaccurate?

 

[tkistre]

The heatsink is very hot to touch. I actually think the motherboard temp reading is pretty accurate. When I originally put it together, I did run Burn In Test on it to put system under load. The system rebooted itself after about 3 hours of running. I figured it did because it probably overheated, but of course not 100%. He uses this PC for office work. He uses Excel, Word and AOL mainly. It has no problems what so ever running these things.

As stated earlier, I called AMD because I though it may be a bad chip. I'm starting to think maybe it is. I'm not technical in exactly how the cpu works, but I'm thinking it is putting out alot more heat than it should, like in defective. It's not practical for me to stick it in another machine since he uses it everyday. But I may have to.

that funny, my duron 1gigahertz vcore says 1.78 in mbm, in bios it says 1.75 (i have a k7s5a) at default voltage @1gigahertz its 39C

@1333mhz (all i did was set fsb at 133) it runs 45C, but i have a new fan coming so it should solve that.

occationally the bios will reset the cpu speed to 1ghz in really pisses me off, it has yet to restart or freeze, so i think its somthing to do with the bios

who knows
