The processor is responding improperly.
The processor is responding improperly.
5.1, 5.0, 4.9, 4.8, 4.7, and 4.6 with different core counts. At these settings, the processor consistently hit its maximum single-core speed regardless of workload. The motherboard features DDR4-3300 memory (limited by the ES IMC), a voltage regulator at 1.4V, and various timings (tCL 16, tRP/RCD 22, etc.). I was operating on Windows 11 22H2 with speed shift disabled, and CPU cores performed well under load. Each core displayed unique clock speeds, with one reaching 4.9-5.1GHz while others lagged. Multi-core tests showed an average of around 3.2GHz AVX2, constrained by the PL1. Recently reinstalling Windows 11 23H2 caused instability; I observed the CPU consistently boosting to 5.1GHz across all cores, with no variation in clock speeds despite settings. BIOS OC remained at 4600MHz instead of the expected 5100MHz. Updating drivers didn’t resolve the problem. I attempted Easy Tune for core tuning but saw little improvement. Intel XTU also failed to stabilize performance. Adjusting all cores to 4.6GHz would restore stability but significantly reduced single-core speed. My goal is to enable smart CPU boosting without sacrificing efficiency.
What power mode are you using? (I'm selecting the standard option.)
Relevant images could help clarify. "I checked what's happening."
The only change was the operating system. My BIOS preferences remained unchanged before and after. I frequently use programs that track and display clock speeds. Would you like me to tally them up? It doesn’t matter if it’s a lot or a few.
I received an Engineering Sample and expected it to function properly. I didn’t purchase a faulty component; it performed reliably for years. I understood what I was acquiring when I bought it. If I encounter difficulties now, it doesn’t imply the sample caused the problem. It’s too late to attribute the issue this way.
Your CPU includes Speed Shift Technology. Windows 11 23H2 appears to presume that if Speed Shift is present, the BIOS must have activated it regardless of its current state. Try turning it on in the BIOS and observe any changes. Disable Windows 11 core isolation memory integrity and related VBS components. These settings block software from accessing CPU data, which could explain incorrect setup. If Windows can't interpret the turbo ratios set by the BIOS, it may default all ratios to 51. https://beebom.com/how-disable-virtualiz...indows-11/ After disabling VBS, restart and attempt to run ThrottleStop 9.6 https://www.techpowerup.com/download/tec...ottlestop/. Review the FIVR and TPL windows for confirmation. The FIVR should indicate that staggered turbo ratios in BIOS aren't being applied. If VBS is off, ThrottleStop should function normally. I’m uncertain if Intel XTU can handle this configuration. ThrottleStop should work fine.
I'm processing this information. VBS is off and security features disabled right after installation. BIOS settings are visible, but speed shift is acting oddly—clock behavior doesn't change even when adjusting it. I'll test manual speed shift via throttlestop. I'm fine with most power-saving options enabled, though speed shift affects latency. Ring down bin remains off because core ratio is set higher than -3. I'll monitor and update you soon.
When Speed Shift is activated, select the Windows High Performance power plan. This automatically adjusts Speed Shift EPP to 0, allowing the CPU to operate at maximum speed without any extra delay. The Balanced plan will reduce CPU performance under light load, potentially increasing latency. It appears the FIVR window's turbo settings are contributing to the issue. Adjusting the Defaults option in the left bottom corner of the FIVR window may help by reading the CPU's default turbo values. This approach works best with an ES processor.
