Undervolting can influence clock performance.
Undervolting can influence clock performance.
It won't impact them, though it might lead to instability. What's the reason for reducing the voltage? 1.2v isn't too high for a 8700k, if I were you I'd go up to 1.300 and check how much speed we can achieve... I'm lucky enough to get 5 GHz with no AVX offset at that voltage.
Unfortunately my 8700k isn't performing well and can't go far. Reducing the vcore to 1.15 cut the temps by 8°C (max 63°C). I also tried 1.1v, but the chip is faulty so it's unstable. Even if I could, I wouldn't push my 120Hz monitor to 3440×1440 resolution.
It may influence clocks; you have some flexibility if it's 63°C with or without the under-voltage.
I adjusted the voltage from stock to 1.2V, which caused a big drop in temperature—from 73°C to 56°C during operation. However, your R20 score fell from 4886 to 4568, indicating reduced performance.
63 is quite impressive for handling loads. It's interesting how you're trying to push the CPU to its limits to achieve maximum temperatures. Even if the results aren't perfect, it still shows a lot of thermal flexibility. For accurate testing of overclocking or voltage adjustments, running the real bench on Asus for an 8-hour session is recommended. If it succeeds, it's likely stable; otherwise, you're not ready. Applying undervolting to Intel won't improve performance—it just leads to crashes because of instability...
It seems you're trying to figure out how fast the CPU runs at different temperatures and voltages. If you're hitting 63°C at 1.35V, that gives you a good buffer for overclocking. You're likely aiming for speeds in the high 40s during gaming. Let me know the exact numbers you're seeing and I can help interpret them!
