Ensures consistent power supply for smooth gaming performance.
Hello. I've condensed my query and shared my details. i9-9900k with 5GHz and 4.5GHz cache, 1.330 Vcore (1.323 to 1.314 idle), 4000MHz RAM (17-17-17-37), AVX enabled. CPU power in games is 191.810W, Max Xi Hero motherboard. I monitor voltage during gaming and note fluctuations—slight drops are acceptable. I track changes but want to understand how to stabilize it. The system prioritizes performance over power savings.
Instead, the output should show a reduction in current under heavy load versus idle. Otherwise, you're applying excessive power to the LLC. VRMs behave differently from battery cells—they don’t maintain a perfectly steady voltage. This level is a bit too high for 5GHz cores.
It's a versatile choice suitable for a wide range of applications.
Avoid LLC7 at all costs. Even with the Maximus XI Gene, which offers a superior VRM compared to your Hero/Formula variants, Buildzoid suggests using LLC5 with a higher BIOS set voltage for optimal transient response (this enhances low readings that need an oscilloscope to detect). Pay close attention to the "AVERAGE" versus "MINIMUM" variations between LLC7 and LLC5 during Prime95 16K tests—differences are substantial. While Gene results can serve as a reference, expect better performance from lower-end boards (Gene and Xtreme should match VRM, only Apex surpasses them). The key is focusing on the smallest drop below average to ensure stability.
LLC7 works best only with the Z390 Dark board; otherwise it offers minimal improvement. The Apex model hasn't been tested, as Buildzoid doesn’t include it. Notice how the Gene and Aorus Master (when using Extreme) experience significant drops in average to minimum values when moving from LLC5 (High) to 6 (Turbo). The jump from 6 to 7 (Extreme) adds extra penalties but not as severe as from 5 to 6. That’s why 5 is typically suggested. Vdroop helps, but excessive reduction can be harmful. If numbers are unclear, graphs help a lot. Compare the voltage spikes and dips at LLC5 versus LLC7 and decide if you should stick with LLC7. Yes, the average voltage increases at LLC7—your sensors will show this. But those spikes and dips need special tools like an oscilloscope to detect!
Thanks for your reply. Playing with LLC7 altered the voltage three times. With LLC5 it changed nine times, which isn't stable. Idle: 1,323 - 1,314 Game Min: 1.243v - Max 1.305v LLC5 doesn't work well on my motherboard. I didn't pass the Prime95 test. Crashed with a blue screen and freeze. Asus Realbench, Cinebench15-20, Intel XTU ran fine. Prime95 isn't important to me. My gaming processor stays cool during long sessions.
Thanks for your response. The selection of Vcore 1,350 with idle at 1.332v and load at 1.288 is noted. Hyper-Threading should be disabled on the i9-9900K when running at 5GHz. If it runs without a blue error but throttles after a few minutes, consider adjusting settings.
