Is the voltage of your 10900k model suitable?
I've been working on researching and adjusting my 10900k OC configurations to match what I've observed, but I'm seeking a second perspective on my settings.
Operating a 10900k at 5.1ghz across all cores.
Testing benchmarks with XTU runs that utilize all cores at a maximum of 1.39v. The peak temperature stays at 80°C. Voltage is configured at 1.35v with auto LLC enabled in the BIOS. Idle voltage ranges between 1.35 and 1.37v.
After some fine-tuning, pushing to 5.2ghz caused crashes, so I reduced it back to 5.1ghz to stay within the 1.35v limit in BIOS. During benchmarking at 5.1, I reached 1.39v, so I checked if lowering the voltage would help. Reading forum discussions suggested keeping idle voltages between 1.3 and 1.35 as safe. I struggled to maintain stability at 1.25v or 1.3v in BIOS—system would boot but crash with BSODs when trying to open XTU or MSI afterburner.
Currently, my setup is back at 5.1ghz with 1.35v in BIOS, though I'm concerned about the idle voltages of 1.39v and 1.3v. Could these levels affect CPU longevity if maintained this way?
1.4v has worked well on older Intel processors. The main reason for quick degradation is exceeding the recommended IMC/VTT voltage, so I avoid going above 1.325v. I didn’t face issues running 1.4v Vcore on first-gen Intel chips for nearly ten years, except for the i7-860 where I increased the VTT to 1.4v.
I adjusted the settings further, changed the core voltage to 1.325 in BIOS, which allowed opening up XTU, but when attempting the benchmark it crashed. I experimented with adjusting the RAM voltage to check for improvements, as they are currently running at 3600 MHz XMP. I also tried setting both RAM and CPU voltages to 1.325, but had no success. I reset the RAM voltage to 1.35 and adjusted the core voltage to 1.34, which worked well for the benchmark with a peak of 1.38. The maximum temperature reached was 78°C. Any suggestions on maintaining this frequency with lower voltage are unclear. It seems lowering the voltage might be necessary if I want to reduce the frequency.
4.8 all core boost. I really see no reason to try to get 0.3 overclock probably no noticeable difference.
Values differ individually.
Similar to manually adjusting an OC Ryzen 3000—rather than relying on the guaranteed approach, cooling and memory—for a comical improvement in performance at the expense of reliability...
