7820x running at 1.2ghz, Please help

[DFryh]

I just built a new 7820x system, CPU z and Intel ETU both show it running at 1.2GHz even when stress testing. I do see Current Limit Throttling flash yes when benchmarking or stress testing with ETU. This is much worse than my 4770k that I upgraded from. CPU is running at 25c.

I don't know a lot about overclocking, using ETU, I adjusted the core ratio to 36 and it's still stuck on 1.2GHz, even under stress test or benchmark.

My specs:

Corsair 750w PS

Corsair Hydro H100i v2

MSI x299 Raider

G.skill ripjaw DDR4 3200

Asus GTX1080

Hello Fry737

Thank you for your response. Could you help us with the following troubleshooting steps?

1. Enter the BIOS (motherboard F1/F2/Delete Key, etc.). Load the default BIOS settings (most likely with F9 key), and disable all the auto-tuning features of your motherboard if available.
2. Run the same test you mentioned in the original post, plus the Intel® Processor Diagnostic Tool available at the following link (please attach the results). https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool
3. Restart the System and enter the BIOS again, look for the processor>multi core processing (option/tab/section – depends on your motherboard) and enable the single core option.
4. Repeat step 2.
5. Provide us with all the reports and if possible screenshots/pictures of the BIOS settings, and info related to the processor (frequency, options, etc. BIOS).

Regards, Leonardo C.
