temperatures reach maximum levels even when any overclock is applied
temperatures reach maximum levels even when any overclock is applied
I'll begin by mentioning that I've been overclocking my GPU for years, but this is my first attempt at overclocking my CPU.
The specifications are:
4790k
MSI 270x 2GB
16GB 1866 DDR3
MSI z97 Gaming 3
Hyper 212 EVO
I've reviewed several videos and read some guides for my chip, but it seems anything above the stock clock reaching 100C happens very quickly in Prime95 or OCCT (Small FFT).
I started with what appears to be a typical safe OC setting—vcore at 1.3 and core clock at 4.5. I've experimented with auto and adaptive vcore, left other settings at auto, and tried both with and without XMP enabled.
Currently, I'm seeing temperatures between 65-72°C at full load with the stock clock. I've adjusted the core clock from 4.5 down to 4.4 and vcore to 1.28, but the results remain similar.
Apologies for any oversight on this topic; I was hoping to achieve better performance than what I'm experiencing. I have a lot of fans installed, and my case offers excellent airflow, so these low OC temperatures don't seem reasonable to me.
Any advice would be appreciated.

For those new to CPU overclocking, the OC Genie is a good starting point.
Hi Terry, I haven't run any tests yet with OC Genie activated, but the stock turbo is 4.4GHz and my temperatures are stable with that. It seems like OC Genie just locks the core clock to a fixed 4.4—does that sound right? Besides that, if I'm seeing good temps on Prime using the stock clock, wouldn't it make sense that the thermal paste is fine? I expected a poor application to cause high temperatures even at stock speeds...
I believe the main clock the OC Genie uses changes based on the processor. If it's similar to the Asus model, there are many options for overclocking. The key advantage is speed, which helps when diagnosing issues. You mentioned you're seeing temperatures between 65-72°C at full load with the standard clock. That's acceptable, but those levels suggest you should aim for lower temps during overclocking. Most users keep the CPU temperature below 80°C at that frequency. With the current cooling setup, there isn't much room to push the frequency higher. The idle speed will stay consistent, but when running at full load it can jump to around 4.0 GHz and then increase to 4.4+ GHz depending on the chosen overclock.
Thanks for the update, Terry. I've cleaned all of my fans and removed any dust from my case. The temperatures are between 23C and 28C when idling, around 70C at full load with OC Genie activated. When using OC Genie, there were no options to pick an OC setting—just ON or OFF—and it set the frequency to 4400MHz. I tried manually adjusting the core to 4.4GHz, but it caused immediate overheating, reaching 100C using Prime95, and then shut down automatically (88C with OCCT). Everything else was set to default. I'm curious why OC Genie works well at 4.4GHz, but manual adjustments lead to overheating. Also, I tested it at 4.1GHz and got the same issue.
The automatic overclock settings will rely on the motherboard configurations for safe performance. I think there might be a setting that is currently set to manual instead of automatic, which could be causing issues. It's quite simple to fix.
I recommend checking out some overclocking videos for this particular motherboard to fine-tune your settings. However, it appears temperatures will likely cap the overclock at around 4.4 GHZ. Different processors handle overclocking differently.
