There will be a downtime tomorrow for some updates and an undervolting test.
The PBO limit is too high and must be changed in BIOS. The CPU is reaching 95°C easily under heavy load which is not good.

Iam expecting 1h for stresstest. The server will not be available at this time.

If your CPU and MB support it, then enable ECO Mode to reduce power/heat. You'll most likely get a boost in performance since it won't be thermal throttling anymore either.

PBO2 is the important thing, the server is running on Ryzen 3950X. PBO has 1.4xV max limit which is too high. I dont like these standard settings.

Settings to test:

- PBO: On, ECO-Mode 95W
- PBO2: PPT Limit: 120W
- vCore Offset -0.100V

For better performance and less Watt / heat

The tests had some crashes and broke the hole OS, I have reinstalled nearly all things but still need time to install the rest. This will give us more downtimes if something must be installed like drivers.

For now after 13h Iam dead ... all for nothing with extra work, no settings in BIOS and the latest for these changes, what a mess.
