Find resources to customize the i9-9900K using Aorus PRO without mastering it.
Hello, I'm looking for guidance on overclocking your i9-9900K with an Aorus PRO motherboard. Since the BIOS is different, I'm unsure if reaching 5 gigabits is possible. I'd prefer a stable speed around 4.9 gigabits or higher compared to my current performance. Thanks!
Could you clarify what sets them apart? Both use Gigabyte Z390 boards, and most manufacturers simply recreate the BIOS with minor tweaks. Usually they adjust the background, memory training methods (when topologies differ), VRM settings for each model, and toggle certain options like Thunderbolt or USB ports. The core structure of the BIOS should remain consistent—multiplier position, voltage section, and power-saving features should match. Your task is to locate the core multiplier setting, set it to 50, adjust the VCore setting with an override and a 1.35V value. Test stability using tools like Prime95 or LinpackXtreme; if stable, you're done. If not, increase voltage by 10mV and retest, repeating until stability is achieved or temperatures rise too much, then reduce the multiplier and try again.
The instructions I reviewed and the video content differ from my BIOS setup. For instance, the Gigabyte guide on tweaking up to 5.0 mentions "Uncore" values for adjustments. That term isn’t present in my BIOS. After attempting the guide, I encountered stability issues at 5.0 and 4.9, so I reverted to the default settings. I’m currently using a be quiet dark rock 4 model. For 5.0 and 4.9, I experimented with voltages between 1.30 and 1.35V, while on 4.9 and lower I used 1.26V to 1.30V—though results weren’t successful. Temperatures stayed in the low to mid-90s range. I also looked at videos like the EASY 5GHZ OVERCLOCKING GUIDE for Z390 Aorus boards, but stability remained limited even with minor BIOS tweaks using AIDA64.
Advanced CPU configurations are recommended, though in practice if you're looking for an overclocking guide, avoid touching core values—it can boost performance slightly but is challenging to stress test. Achieving 5GHz typically needs a voltage between 1.35 and 1.4V, while 4.9 should fall within 1.33V to 1.37V. It seems you're not providing enough voltage to make it function, possibly due to a lucky silicon outcome.
Thanks, I’ll give it another shot with those settings. I was already in the mid-90s, so this cooler should work fine for the task. The text about the uncore likely came from an earlier BIOS release. It seems like a ring ratio setting—previously tried at 47 (4.7)—but I couldn’t get past BSOD in the 5.0 region or during high temperatures when the PC started with lower voltages or speeds.
Yeah, the changes between different boards seem confusing. I’m not sure if there’s another one I missed based on the manufacturer or revision details. It’s possible, though, that the naming varies between makers. The 4.7GHz speed is likely too high for this chip, probably making it harder to handle. Auto settings probably sit between 4.0 and 4.2, which should work fine. Cooling is a big issue—keeping temps below 100°C is essential, especially if you’re trying to overclock. If the board is known for poor cooling, that could be the main problem.
