Hi everyone,

what is meaning of values of parameters: "Target CPU / Cache / BCLK speed" in UEFI: "OC Tweaker\CPU configuration" menu?

If I set value of "CPU Ratio" there to "auto" it sets values:
"4900 MHz/ 4300 MHz/ 100.0000 MHz",

but for "CPU Ratio: All core" and next "All Core: 36" values are:
"3600 MHz / 4300 MHz / 100.0000 MHz"

Which parameter shall be used for i7-9700K, that has base clock 3,6 GHz and 4,9 GHz in turbo? Do settings there impact on CPU voltages?

My question is related to problems with jumping out NVMes. I have suspection, that motherboard somehow is short on amps on CPU-PCI lines, that causes NVMe to disconnect. In such sitation Windows stops with error WHEA_UNCORRECTABLE_ERROR and no memory dump is written (perhaps because storage is gone).

I appreciate any help.
