Troubles with 13900K? ASUS AI upgrades it to 6.1GHZ...
Used ASUS AI tuning for my 13900K since I’m new to CPU overclocking. AI Suite 3 lists the CPU at 6GHz or 6.1GHz, but a stress test on Prime95 drops it to 4.6–4.8GHz while drawing about 200–250W. The turbo reaches 5.8GHz, yet I don’t see speeds near that at full load. I’m trying to let the motherboard push the CPU beyond Intel limits as long as temps stay under 90°C. During the stress test it stayed stable around 78°C. Could be I need a manual overclock attempt? My last experience was with a 9700K on a Gigabyte board, which simplified things.
5.8GHz is designed for single core turbo. With additional cores, the lower the clocks will be unless you adjust your OC settings manually. See the details here: https://www.techpowerup.com/review/intel...0k/24.html
P95 runs with all components together, which means its clock speed is less than the 5.8Ghz turbo version since it uses just one core at its peak. What kind of cooling system keeps the 13900K chip from overheating to 78°C?
These auto-overclocking tools usually don’t add much value. They often inject excessive voltage without purpose, behave badly on most processors except special ones, or actually slow things down compared to stock performance. In my case, I’d keep the chip at its original speed. It should hit around 5.5GHz on P cores during heavy synthetic workloads, and unless you’re forcing extreme voltages for cooling, you won’t surpass 5.6GHz consistently across all cores in P95. The jump from 5.8GHz to 6GHz or 5.5GHz to 5.6GHz won’t be easily felt. Manual tuning makes sense mainly for XOC and the 13600K/13700K, where the chips have usable headroom.
Use the Cooler Master PL360 Flux AIO paired with Noctua paste inside a CM HAF 700 Beserker case.
The i9-13900K offers more advanced features compared to your i7-9700K. As noted by others, the advertised maximum single-core boost reaches up to 5.7/5.8 GHz. Even adhering to Intel guidelines, it only sustains short bursts. The base frequency stands at 3.0 GHz for P-Cores and 2.2 GHz for E-Cores. https://www.intel.ca/content/www/ca/en/p...tions.html 4.6 GHz to 4.8 GHz under full workload or stress tests like Prime95 is typical. Continuous operation at 5.80 GHz, particularly across all cores, will likely breach the 125W power limit and generate excessive heat. Yes, it’s wiser to study, investigate, and adjust settings manually instead of relying on automatic overclocking.
Check the CPU's actual clock speed and adjust it to match your hardware capabilities. If using a fixed frequency like 6GHz, ensure it aligns with the processor's supported range. Consider updating drivers or optimizing settings for better performance.
