i have an a10-7950k and its performing terribly at the moment. I've tried reinstalling CCC and drivers or whatever but I can't get it to really do anything graphically. Some weird symptoms: nothing in this world can detect my processors temps, the graphics temps are reporting to be around 10 C, and while I was testing in passmark I noticed my RAM scored dismally as well. Here is my part list: https://pcpartpicker.com/user/noshness/saved/YQXRsY
I mean it can't run league at any resolution really. That's how bad we're talking. And I've attempted that, I think the speeds are correct based off cpuz.
Then again the tRC is different on cpuz and passmark, one says 31 and the other 29 -.-
I've got the little brother of your CPU (The A10-7700K) and it has no troubles, so yours should be plenty capable. According to CPU-Z your memory appears to be fine.
Try GPU-Z and post what that says. I've seen a couple rare cases with previous gen APUs where there would be a defect in the GPU that halved its memory bandwidth. I'll go try to dig that up and see what I can find.
