to maintain silicon stability within the operating range, which tops out at 95°C https://www.amd.com/en/products/cpu/amd-ryzen-9-3900x with power and heat fluctuating 5-10% and some random calculations, for the R6 2600 under typical conditions on a 2600 chip, if silicon temps reach 80-85°C the cores will run at full capacity; above that range the cores will throttle down.
I know there's an option somewhere in windows that prevents the CPU from "clocking down" (or "clocking out" lol). When I did this with my last CPU, it locked all of the cores at the boost speed. Agree with everything you've said. Just wanted to make sure nothing was wrong with my chip
What hardware are you using? Download the burner and review everything online, especially regarding memory boosting. I'm enjoying my setup and discovering various tips and tricks—not just from one site. Buildzoid is a solid source, but first focus on determining your peak fCLK (infinity fabric) boost and your highest safe CPU voltage. Use PBO for the overclocking, then run XMP and a memory check for an hour or so. If everything holds steady at that fCLK—both with stress testing and Prime95 AVX—you can start adjusting RAM. You want to push memory and CPU because infinity fabric handles both communication paths. Make sure your RAM matches the fCLK (double it for DDR, e.g., 3200 MHz becomes 1600 MHz) and aim for a voltage of around 1.45V for DDR4. Increase RAM to this level, then fine-tune. Start with just the primary settings (CAS, tRCD, tRP, tRAS), stress briefly, then reduce them. Once stable, add tertiary timings from your calculator and begin experimenting. Keep in mind that RAM stress will impact stability, especially since DDR speeds double the clock speed. A long 8-hour stress test is advisable due to temperature effects.
Hi Guys. How can you prevent the CPU from running below the base clock? Should I disable global C states? I have a 3800X that fluctuates between 3.6 and 4.5GHz. I’m wondering if keeping it at the base of 3.9 and boosting to 4.5GHz would improve performance.
