Hey Guys.

 

System:

CPU: 3700x

MB: Asus Tuf Gaming x570-Plus Wifi

Mem: Crucial Ballistix 32GB 3200mgz 2xdim

Cooler: Corsair h150i pro rgb

Graphic: Evga 980 ti

 

So i've been having problems with my cinebench test and it seems like my CPU is throttled during load.  However during Idle it runs fine.   So i've noticed that my CPU has been idling pretty hot.  Sometime it will be from the 40c - 60c range when just browsing websites.  Then i noticed my CPU Core Voltage was pretty much stuck at 1.45 to 1.5v.   Which seems pretty high during idle.  As i'm trying to figure this out, i've started running cinebench r20 and noticed immediately that my core clocks drop to 3.8mhz and voltage drops to 1.2v.   I've checked the temps and it never goes past 76c.

 

I just updated the Bios to the Asus-1201 bios and that seems to have fixed the voltage issue.  The cpu still idles pretty hot at 45-50c.  The voltage idles at 1.019v but occasionally spikes to 1.4v.   When i do the cinebench test, it still drops the cores to 3.8mhz and voltage to 1.2v.   I'm not sure whats going on.

 

I've set my bios to be Auto at everything and turned off xmp.   I've set the Power plan to AMD Ryzen Balanced and High Performance.  I've turned off ICUE, Ryzen Master, AI Suite 3.   Nothing.  I'm at a loss. 

 

Do i have a bad CPU?  Also it's not just cinebench.  I noticed i get a warning when I play Heroes of the Storm that my CPU is being throttled.  

 

Attach or two SC of my HWInfo.  One was turned on during the test.  You can see the core never passed 3.9mhz.  however the moment the test is done and the system idles, it goes up to 4.39..
