10900KF Overclock?
10900KF Overclock?
Hey there! I see you're looking for some advice on your 10900kf setup. It sounds like you've got a solid base with your components and BIOS settings. Since you're not sure about the "SP" rating, maybe checking that could help clarify what's working well. Your current load is around 5Ghz with stable temps, which seems healthy. The fact that it doesn’t drop under gaming or Cinebench suggests your cooling and voltage settings are in good shape. If you're considering pushing it higher, keep an eye on those temps and stability—don’t forget to stay within safe limits. Let me know if you want tips on tuning further!
You're seeing mixed advice about C-states. Some say they need to be turned on for downclocking, while others suggest they might not be essential. It’s good you’re checking your card’s specs—performance can vary. If you want better speed, focus on the right settings rather than just enabling features. Let me know if you need more details!
Your BIOS indicates C-states are active, but you're experiencing performance around 4.8-5.0 during idle.
Other factors might be at play, though I can't pinpoint them. C-states, speedstep, and speedshift are all active. The balanced power plan is set, and I verified the minimum CPU state.
Ensure your C states remain active for optimal power efficiency. Reducing CPU speed during idle periods offers minimal impact on energy use. When cores switch to low-power mode, they disconnect from the clock and voltage lines, operating at 0 MHz and 0 Volts. A 10-core processor may spend over 99% of its time in this state when idle. Limiting overall CPU activity is unnecessary if C states are enabled. The Balanced power plan decides whether to throttle performance. Access Power Options and restore the default Balanced plan. Speed Shift Technology responds swiftly, but some software struggles with rapid adjustments. Use Task Manager to check idle load; excessive activity prevents effective throttling. Some users mistakenly believe their machine is idle when it isn’t. For instance, a 10900KF can run smoothly at 5.1 GHz or 5.2 GHz across all cores, but voltage and power usage will rise noticeably. The slight performance boost rarely justifies the minor power increase.
I attempted a 5.1ghz all-core OC with power savings turned off on my 10900KF. Eventually, I adjusted it to the fixed 5.1ghz voltage, disabled power limits, and tweaked the active turbo multipliers. Kept the standard c-states and configurations. Settings: 53x 1-5, 52x 6-7, 51x 8-10. Idle at 800MHz, but mostly stays at 51x and works well after an hour of RealBench testing—perfect for me. YMMV
You're focusing more on performance than power savings. It makes sense to reduce speed when full OC isn't needed, especially if you're trying to manage heat. The idea of lowering the clock at idle or low usage is reasonable. Usage during desktop tasks or idle time is only a few percent, so keeping a steady high speed wouldn't be ideal.
