My temps stay low but similar to yours. My voltage is much lower than what you're showing. With four cores disabled I'm able to run the remaining cores stable at 1.2250 CPU Over Volts. Which @ 4.4Ghz is really low. But its also how I got everything running nicely, as I get zero throttling with the voltage this low. I get a bit of throttling @4.5Ghz which requires 1.26250 Volts. So I stopped using that setting 4.5Ghz over the last year. But what you are showing (assuming your throttling is minimal) is probably fairly sane for your CPU.
One thing I started researching this year is which of the past AMD chips have 8 or 4 Cores, but have pairs that share FPS. Which gets into a complicated discussion about how these chips might run optimal for games. As most people know very very few games can make use of more than 4 threads. Now with most boards running FX chips you almost always run into VRM overheating issues. So you run into the question should you run less cores with higher clockspeed, or run more cores with lower clockspeed.
It seems like the obvious answer would be higher clockspeed. But by disabling cores you really are disabling paired core modules. Which means you are giving up shared FloatPoint schedulers and some shared L2 and L3 cache. (An eight core processor only has four shared float point schedulers). In past windows OS's this was moot because windows didn't schedule the AMD threads correctly anyway. But currently a fully patched windows 7 and windows 10 will schedule tasks across the first core in each module first and then follow with the second core in each module (making full use of each FPScheduler and L2/L3 memory) The question then becomes is it worth losing 0.8 to 1.0 GHz to enable all 8 cores in order to pickup full use of the FPS and L2/L3. The problem is 800 to 1000Mhz is considerable power, and the third and forth thread in most games only bounces in sometimes.
Anyway more food on the fire for how complex CPU consumption is with these processors and motherboards.Edited by Katrisa - 4/22/17 at 10:49am
