The setting can be found in the CPU core ratio on ASUS boards. Here I have described it: On 3/3/2020 at 3:27 PM, StreamFidelity said: 2.1.3 CPU clock frequency The most important setting for high performance concerns the clock frequency of the CPU. The Intel Core i9-9900K has a base clock of 3.6GHz. Not enough for the EC modulators of the HQPlayer. At least 4GHz on 3-4 cores are required. The CPU has 8 cores. I experimented with different settings. For example, clocking the first cores higher than the following ones. I did not like it. I stayed with the simple configuration: all cores on 4.1GHz. AO also recommends using a fixed value, see manual.

TDP is the maximum thermal power loss on the basis of which a cooling solution is designed. Important: This is a nominal value. The TDP says nothing about the actual energy consumption! For an i9-9900K with a TDP of 95W, my power consumption is about 31W. Although all cores run on 4.2GHz and DSD256 is played with ASDM7EC. You can get that with Undervolting. Since I use two linear power supplies (Keces P8), the consumption is of course higher because of the power dissipation. 20V with 1.8A = 36W 12V with 4.0A = 48W Total = 84W 😉 luisma 1 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A Link to comment

Otherwise you will have problems with the temperature. With an average CPU load of approx. 16%, the average temperature is approx. 59°C. When the filter poly-sinc-short-mp is loaded for the first time with PCM 44.1kHz to DSD 256 (ASDM7EC), the CPU load jumps to 100% for a few seconds. The HWMonitor then shows 53W, which is still little. Keces P8 for the CPU jumps up to 12V / 5.5A (the limit is 8A). The i9-9900K core would draw a lot more power if I hadn't limited the cores to 4.2GHz. On ASUS mainboards there are additionally settings for the maximum power: - I have the power consumption at 120W with max. 160W limited Other possible settings support this: - The CPU i9-9900K can up to max. 100 ° C operated.
