Can you confirm if it's secure to push an i5 4670 non K to higher clock speeds?

Non K versions have limitations, but it's possible. Is 400 MHz the upper limit for non K models? I've enabled auto voltage settings so the BIOS can manage it. This change is safe. Regarding CPU cache, the minimum should be automatic, and the maximum depends on your target clock speed—like 4.0 or higher, not necessarily 4000. Should turbo boost remain active? Your specs include an ASUS Gryphon Z87 motherboard, I5 4670 CPU, Arctic cooler GT rev 2.0, GTX 760 GPU, 16GB RAM at 1333mhz.
AuroraHD is planning to test the setup. They want to see if syncing all cores to 3.8 ghz with turbo boost enabled maintains a stable 3.8 constant. If not, they'll adjust settings in Windows Advanced Power Options to "High Performance".
Additionally, what temperature is required for the CPU to activate turbo boost? I noticed it fluctuating between 3.4 and 3.98 before stabilizing, but it doesn’t hold steady. On BF3, the frame rates drop to 70-100 and vary a lot.
With an Intel non-k CPU, overclocking is limited to the Turbo Boost setting. You already have a suitable motherboard and a reliable CPU cooler, so no issues there.
Ensure you update the BIOS settings. After tweaking the multiplier, turn off Turbo Boost and keep EIST active. This prevents the processor from running at maximum speed continuously.
You may modify the CPU voltage (VCORE) to help lower the temperature. Given only a 400Mhz clock increase and a good cooler, this is usually not required.
The CPU's Turbo Boost feature allows the multiplier to be modified, though not as extensively when unlocked. Increasing the multiplier beyond its Turbo Boost limits can be risky, so proceed with caution. EIST functions similarly but reduces the clock speed for less demanding operations instead of boosting it.
Consider setting voltage to auto or adjust it as needed. Also, ask about the highest achievable clock speed.
