MSI’s Loadline Saturation BIOS Feature For Z790 Motherboards Maxes Out Performance For Intel’s 13th Gen CPUs
Based on what we have been able to gather, the MSI ‘CPU Loadline Saturation Control’ feature will be added to high-end Z790 motherboards that feature a Renesas VRM controller. The feature can be enabled within the BIOS and will automatically decide whether to apply CPU loadline calibration settings to the CPU current under load or not. Users can also apply different loadline calibration on their CPUs, manually (Vdropp), to max out both single-core and multi-core overclocking capabilities. With this, users can enjoy faster single-core and multi-core overclocking and performance. The following MSI Z790 motherboards can enable this feature with Intel’s 12th Gen & 13th Gen CPUs:

Following is how the various BIOS functions on MSI’s Z790 motherboards work with Intel 13th Gen CPUs: CPU Loadline Saturation Control: If CPU current is higher than the ‘CPU Loadline Saturation Level’ threshold, ‘CPU Loadline Calibration’ settings will apply. If the CPU current is lower than the threshold, the setting will not apply and thus there’s no Vdroop. Usage Scenario: Here is an example of the benefits of CPU Loadline Saturation Control when overclocking the Intel Core i5-13600K CPU on the MSI Z790 motherboard. Hardware Configuration: Loadline Saturation – disabled vs enabled Without Loadline Saturation, you can only apply one Loadline Calibration setting for both single-core and multi-core workloads on the MSI Z790 motherboards. However, with Loadline Saturation enabled, users can apply different Loadline Calibration settings (Vdroop) for single-core and multi-core workloads. Here is the test result with Loadline Saturation. As the table shows, Loadline Saturation helps to max out the capability of both single-core and multi-core overclocking, with the help of different Loadline Calibration (Vdroop) applied for single-core and multi-core workloads. Performance Benefit Here is the performance of a stock Intel Core i5-13600K overclocked to 6.1GHz single-core / 5.6GHz multi-core running on an MSI Z790 motherboard. CPU Loadline Saturation is helpful to max out both the single-core and multi-core overclocking capability and performance.
