3950x 3950x boost problems

[HarvDaMan]

So i just got my shiney new 3950x and a asus prime x570 pro motherboard, i noticed that when i put the CPU under load it throttles down to 3ghz (sometimes 2) and core voltages drop to 0.95.

before you go is this person stupid, it never goes past 60 degrees celcius, i have the 8 pin plugged in, i have updated chipset drivers and bios to newest versions, i have tried disabling precision boost and re enabling it, i have tried using a different cooler (although that doesnt seem to be the issue) and i have tried re installing windows on 2 different drives, its the weekend and i cant get hold of AMD or ASUS customer service till monday. does anyone have any ideas of how to fix this other than manually setting core voltages

 

CPU: 3950x

GPU 980ti
PSU: Corsair TX 750M

MB: asus prime x570 pro
Cooler: Corsair h100i PRO XT

RAM: corsair vengance LPX 16GB 2x8 2440MHZ (for some reason even with AMDs XMP clone enabled it stays at 1168MHZ)

 

 

 

 

** UPDATE **
so someone told me to manually set the core voltage to 1.3 and the base multiplier to 40 (4ghz) this has worked and now i dont get any stupid throttling but it would be nice for a more permanent solution. Thanks to everyone that helped me and if you know of a more permanent fix i would greatly appreciate it if you could pop it in the replies.

have u tried switching to high performance mode in windows power setting? some games or apps arent made properly and cpu clocks will drop while under load at fine temps, whic should never happen

Use a resource monitor like HWinfo, not task manager.

Make sure that Core Performance Boost is Enabled and PBO is set to enabled. I'd load BIOS defaults, set those two options and see what happens when it reboots.

 

Maybe update BIOS if you can in case it's not got the right patches. ABBA 1.0.0.4B is the latest and recommended patch I think.

Do not manually set the core voltage. Let the CPU do it's thing. Especially at factory clocks. Sure it looks scary sitting at such a high voltage given the silicon but AMD knows what they're doing.

 

If you want to manually set the voltage then you should also manually overclock it. You might lose a bit of single thread performance but gain quite a bit of multi core performance.

i did, one of the screenshots attached is a HWinfo validation of my CPU

I may sound stupid but it happened to me before, I once plugged PCI 8 pin connector to CPU's 8 pin connector, Somehow the notches matched and it got plugged it, the PC booted up but my CPU had the same problems as yours, are you sure you got the CPU running on CPU 8 Pin connector and not PCI 8 Pin connector?

it has CPU printed on the side of its connector and its a fixed cable in my semi mod PSU so its the right one
