CPU 4.8GHz vs 4.9GHz
CPU 4.8GHz vs 4.9GHz
If benchmarks aren't scaling linearly, it likely points to another issue. Your CPU might be overheating and reducing performance, or there could be a bottleneck elsewhere (like RAM speed or timing). Or maybe your overclock isn't stable. Choose one, as one explanation is probably correct.

Execute the test across all configurations repeatedly—scores fluctuate, possibly due to an unusually strong result at 4.8 or a slightly weaker one at 4.9 from random chance. Multiple trials will provide a clearer understanding. (However, a 100mhz variation won't significantly impact performance.)
If you're not seeing linear scaling in your benchmarks, it could indicate another issue. It might be that your CPU is overheating and throttling, especially with Intel processors which often do this silently. Alternatively, you could be limited by other factors such as RAM speeds or timing settings, or your overclock may not be stable. Choose one possibility, as one of these is likely the cause.
Your PC specifications:

- Graphics Card: GeForce GTX 1070 8GB Fabric OC
- CPU: Intel Core i7-8700K (4.8GHz OC)
- CPU cooler: Corsair Hydro H115i PRO RGB
- Memory: Corsair Vengeance RGB DDR4 3600MHz 16GB
- Main hard drive: Samsung 970 PRO 512GB PCIe M.2 SSD

Your RAM has a CL18 speed (18-19-19-39). During a 4.8GHz overclock, I ran for 10 hours straight at 95% and 8 hours at OCCT without any crashes.
VCSAA 1.15
VCIOO 1.15
VCore 1.280
CPU cache: 44
Memory settings adjusted to match the same timings and a voltage of 1.350, which matches the RAM sticks.
If this frequency is ideal for you, I’m confident in sticking with it. However, if pushing to 4.9 might be necessary, consider adjusting settings such as voltage upgrades or cache tweaks.
the ram looks good. i don't believe it will cause a problem. i think the overclock might need a bit more voltage or it could be overheating.
The RAM looks good, so it shouldn't be a big problem. I think the overclock might need a bit more voltage or it could overheat.
Sorry, I'm not very experienced—what exactly causes overheating? Are you asking if the CPU needs more voltage like 1.3V or something similar? 😊
i believe these components could require around 1.4 to 1.45V to reach speeds of 4.9 or 5.0ghz
I believe those chips could require around 1.4 to 1.45V to reach up to 4.9 or 5.0ghz.
Yeah, I tested Cinebench just for fun and got a blue screen at 1.35Volt; I need about 1.38V to avoid it in Cinebench.
But I don’t really grasp why my Cinebench score around 4.8GHz is only 1530-1555.
When I see others with a 4.7GHz clock getting 1540 scores, it’s confusing.
As I mentioned, the CPU is running at a lower voltage, and the overclocking isn't stable.
