help for prime95 test 8600k overclock at 4.8 GHz and 1.280 V
I understand these could seem silly, but I'm just starting out with OC. I have an i5 8600k on an ASRock Z370 Taichi overclocked to 4.8GHz with core voltage between 1.280 and 1.296V and a H100i cooler. The memory frequency is around 3998.0 to 40001.0 MHz. I ran prime95 and worker#1-6 through Self-test 24k for about 25 minutes or longer, temperatures reached up to 87°C then dropped to around 60°C. Is this a positive outcome? Should I try overclocking further? Would a better cooler like a Noctua NH-D15 or a new watercooler help? Is 4.8GHz a good balance? I know 5GHz is ideal but I'm still a beginner. Please help or give me some advice.
Hi drew209cali,
4.8GHz is ideal. It needs minimal voltage but tends to heat up a lot when overclocking or cooling down.
Is your voltage set to AUTO?
What’s your average temperature?
Regarding the cooler, think about its lifespan—eventually it will fail. Consider using an airflow solution like a Noctua NH15 or a Dark Rock Pro 3/4.
Tips: Keep temps under 80-85°C during stress tests and below 1.35-1.38V for regular use.

Hello drew209cali,
4.8GHz is perfect for that balance. It needs moderate voltage but your temps look high for both overclocking and cooling.

Regarding the cooler, think about when it might fail (it will), consider switching to an airflow solution like a Noctua NH15 or a Dark Rock Pro 3/4.

what does mean temp mean? sorry. i had it set at 1.85 v but after posting this i lowered it to 1.75 v but didn't really run a long stress test because i need to go to bed for work in the morning but i think the temp just dropped about 1°c from before.
Mean temp represents the average temperature during the stress test; a spike to 83°C with a mean of 60°C is acceptable, but a mean of 82°C is just okay. Are you certain about the voltages you provided? With those, your CPU should be dead right now. Rodolphe.

Sorry it changed from 1.285 to 1.275.
Voltage is fine.
How about your typical temperatures during AIDA64, Intel burn tests, OCCT, or Prime95?

I haven't used them yet, but once I'm off work I'll download them and let you know.

I just ran the Intel burn test and it finished in 87.83 seconds. I also dropped to 1.270 v, with temperatures reaching up to 82°C.
