Processor Throttling at potentially low temperatures

by Tenuto12 / January 19, 2016 6:19 PM PST

While running CineBench my A10 7870K APU throttles as it reaches 35 degrees Celsius thermal margin. The clock speed dials back by 1Ghz at times and this affects my score. From my understanding 35 degrees Celsius (thermal margin) under load isn't that hot. Is there something wrong with my processor??

There are long painful discussions about APUs

So in short such a benchmark taxes the memory channel and it may look like CPU throttling when it's just the memory channel is soaked and the CPU can throttle back since it can. As there are priors, I stop here.

Test this with the side panel off.

Tell that you have 2133 ram set up in dual channel mode.

Ambient Temperature Decreased + Removed Side Panel

Thanks for the response! My removing the side panel and decreasing my ambient temperature I was able to get my highest score of 330. However, after testing it again it drops again. Also I am running 2133Mhz RAM in dual channel.

See if you can change that margin.

AMD OverDrive

Yes. Im using AMD Overdrive as I've heard it's the most accurate way to measure APU temperatures under load. I heard it's not very accurate for idle temps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
