Specs:

OS: Microsoft Windows 10 Enterprise LTSC (x64) Build 17763.615 (1809/RS5)

CPU: Ryzen 7 3800x

MOBO: Asus ROG Strix X470-F Gaming

RAM: Corsair Vengence 32GB, 3200Mhz

GPU: ASUS ROG STRIX GTX 1070 Gaming OC

BIOS: 5204

Cooler: NZXT Kraken x52



I am at my wits end with this... I've done everything I could think of, I've even replaced another cooler with the Kraken x52, which is what i'm using now. I am getting ridiculous temps idle, and high load. I also see my core voltage always spiking to 1.45 (doesn't go down) (is this normal??) When running Prime95 or Cinebench, I am immediately spiking to 95c, and my core voltage is dropping to 1.2-1.1v, and i'm seeing my peak speed drop as well.. (see the second pic)


Things I've attempted:


1. Updating the bios, and the chipset to the latest version available (as per this post: https://community.amd.com/community/gaming/blog/2019/07/30/community-update-5-let-s-talk-clocks-voltages-and-destiny-2 )

2. Set my power plan to Ryzen Balanced

3. Reset the bios by pulling the battery.



I'm also getting this strange thing, if I set my RAM timings by using the XMP profile, my computer doesn't want to boot. I have to set it to below 3200Mhz, and then restart, and go back into bios and set it up to 3200Mhz for it to boot at the right frequency.









(I think the minimum processor state should be 10%?)

I just took a screen shot of what I have at the time.



Any suggestions on what to do would be appreciated..

Have you tried setting the power plan to power saver? That helped me out a lot when I had the stock cooler on my 3600. Also, Windows 10 1903 is recommended for the new Ryzen CPUs

Whenever I reset my BIOS I always pull the battery out, short the CLR CMOS jumper with a small screwdriver, wait 1 minute then re-insert the battery.

Benchmarking software like Prime do make the CPU go up to 95c but you will never get that load during gaming or even rendering software.
What are your gaming/intensive application temps?

I set a voltage offset of - .100 on my Ryzen 2700x which really helps temperatures while still allowing it to boost.
So that is worth trying.

I figured it out... If Prime does make the CPU go up too 95c, then I'm golden, IT WAS ICUE CAUSING MY VOLTAGE TO STAY CONSTANTLY AT 1.45...

Are you running prime95 with AVX instructions or not? Cause if you are running with AVX, yeah no wonder you are hitting very high temps.

Another problem is that you are on windows 10 build 1809, which is not officially supported by 3rd Gen Ryzen. If you want the CPU to run correctly, you need to upgrade to 1903.

Also, read this:

That would mean I would have to go too Windows 10 Pro, instead of LTSC urgh! I guess I dont have a choice.
