A10-6800k 100c

Well, only the cpu bit is running with a stock cooler, the gpu in it is off, due to a wild 750ti that appeared on the horizon of my cubbards, but 100c? that can't be right, good luck uncovering it! (Help Ig)

Reseat cooler?

I haven't used a piledriver based APU, but when fiddling with my bro's 7850k the only monitoring software that reported correctly was AMD's Overdrive.

 

What are you using to look at temps?

[ShiroArikawa]

Everything. Bios too, the reason why I believe the 100c is correct is cause bios said 53c at idle. Lol

BIOS actually loads CPUs a lot more than idling on the desktop. Download Overdrive and see what it says before pulling the cooler off.

 

Your "problem" (I don't actually think it is that hot) is just like the 7850k I set up. All other software (and BIOS temp reading) was reading hot. Downloaded Overdrive and it showed much lower temps, this was also backed up by the fact that the heatsink was cool to the touch and the CPUs sustained turbo clocks under stress testing loads.

Does that explain my turbine? Ahem I mean stock cooler going at its full 3000 rpm with a custom fan curve to only do that at 80c+

Not only do most programs report CPU temps incorrectly with the APU's,  but the temperatures that are presented to you are not core temperatures.  There is a socket temperature sensor and there is a sensor that determines how far away from MAX temps the cores are.  The temperature you are seeing in BIOS is the socket temp.  Socket temps are usually about 10 degrees celcius more than core temps under load.  To best determine the temperature of the APUs it is recommended (Necessary) to use the distance from MAX temp reading when under load and the socket temp during idle.

 

All of this information is directly available from AMD, they flat out tell you AMD overdrive is the only program that will show accurate temperatures for APUs. That is not actually true, there are other programs that do read the temperatures, but they do not display them correctly. So unless you verify those temperatures against AMD overdrive you can't be sure they are correct.

 

Another thing, as far as I'm aware the APUs have a hard thermal barrier.  That is, unlike the FX chips where you can turn off thermal throttling, you cannot turn off thermal throttling of the APUs.  It doesn't seem to matter because the point of diminishing returns for overclocking the APUs is pretty lowly.  I have a 7850K that I have settled on 4.2 GHz with (920 Mhz GPU) because it's unstable above 4.4 and barely performs better than 4.2.  There is definitely limitations due to my motherboard, but my point is I think unless your heatsink is not seated properly, you shouldn't have to worry too much about the APU destroying itself from heat because it is smart enough not to.

I was definitely confused the first time I saw 95 C for CPU package temperature in HWmonitor while the CPU was idling and I was touching the heatsink and radiator hoses and they weren't even warm to the touch.

 

Hopefully this becomes more widely known because if you search around on the internet there is a lot of confusion about overclocking APUs.

Where is the fan curve set?  In BIOS?  The stock coolers are loud, you are sure it's at full speed?    If the fan curve is set in BIOS, it should be using temperatures from BIOS and because it's a board designed for APUs the boards will correctly read socket temps.  If the fan curve is set in AMD over drive I would also expect it to behave correctly.  However, if the fan curve was set in another program I could imagine the erroneous CPU temperatures to cause problems.

[ShiroArikawa]

It was in the bios, 40c is at 40% 60c is at 75% 80c is at 100% (smooth incline in the middle)

[tbake0155]

I'd try setting the fan settings to automatic, in fact I'd revert the BIOS to default.  Then I'd check the temps with AMD overdrive, and I'd probably carefully feel around in the case to see how things feel. I have shorted a board that way, pushing a custom bare copper heatsink into a smd capacitor, but if you're careful you should be able to touch the heatsinks.  If you can touch the VRM heatsink or CPU heatsink and leave your fingers there, it's not 90 degrees anywhere.

 

You could also use a heat detecting laser, probably safer, but not necessary.

Again, download Overdrive to confirm if there is a temp problem or not. If it shows you are at Tmax, you have a problem. If you have a lot of margin, ignore your other readings and adjust your fan curve. It takes 5 minutes to be sure, please see what Overdrive reads.

I am also @ school atm

Oh bummer, no wonder you are theory crafting so hard

 

Best of luck when you get home, I honestly think you are okay temp wise! My bet is Overdrive and a cool heatsink will ease your mind that temps are in fact okay and you'll be able to simply change some fan curves! Give an update when you get a chance

[ShiroArikawa]

Eh, it's not my main rig, but yeah.

Re seat the cooler. It should NOT be that hot.

[Jumper118]

i cant be 100c. not possible for it to get that hot without shutting down on an amd chip.
