For fine-tuning of the board's power profiling, MSI includes multiple levels of loadline calibration (LLC) profiles, with levels that can increase or decrease CPU VCore VDroop depending on the complexity and intensity of the workload. When it comes to memory overclocking, MSI also provides plenty of options for overclocking the frequency, adjusting Intel's Geared memory mode in either 1:1, 1:2, or 1:4 ratios, as well as lots of primary, secondary, and tertiary latencies to customize. In terms of voltages, MSI also includes an extensive list of voltages including CPU VCore, iGPU (CPU GT) voltages, as well as individual P-Core and E-Core VCore voltage options. MSI offers plenty of CPU overclocking options, including separate P-Core and E-Core ratio multiplier controls, CPU AVX ratio offsetting, as well as CPU Ring Ratio, and integrated graphics ratio multipliers. Looking at the overclocking functionality of the MSI MPG Z690 Carbon WIFI, all of the overclocking options can be found within the OC section of the Advanced mode in the firmware. Experience with the MSI MPG Z690 Carbon WIFI This means adequate power being made available from a reliable and quality power supply is needed, as well as good quality and premium cooling such as AIOs, or even custom water cooling. Make no mistake about it, Alder Lake is power-hungry, even more so from personal experience when overclocking than was the case with 11th gen Rocket Lake. This gives two areas for users to consider when it comes to overclocking.Īnother point of note when overclocking with Alder Lake, like with 11th gen and 10th gen, performance out of the box on both sets of cores are squeezed out via turbo, e.g., the P-Core Turbo on the Core i9-12900K is 5.2 GHz, while the E-Core turbo is 3.9 GHz. Fundamentally when paired with a Z690 motherboard, both the P-core and E-cores are unlocked. In contrast, the E-cores don't have as much headroom or scalability as the P-cores. Having personally taken some time to investigate overclocking ability with the Core i9-12900K before diving into motherboard reviews, I found that the P-cores offer much more in terms of performance. The basic idea is that the P-cores do much of the front-loaded heavy lifting, the grunt work, so to speak, while the E-cores assist in the background with high-threaded workloads with a much lower overall power draw than the P-cores. While Hyperthreading isn't a new technology, the hybrid nature of Alder Lake combining two different types of CPU core is. Focusing on the Core i9-12900K, it has 8 P-Cores, 8 E-cores, and 24 threads in total. Intel's latest Alder Lake processors feature a hybrid design with P-cores (performance) and E-cores (efficiency). This is because not all of its cores are equal. When it comes to overclocking on Intel's 12th generation processors, Alder Lake has a new yet important variable to consider.
