Looking for assistance with boosting the I5-7600K's performance?
Hi!
I just installed a new gaming PC and here are the details:
https://pcpartpicker.com/list/nQQRd6
After applying TPU 2 in bios, my CPU runs at 4.8GHz with 1.35V (occasionally jumps to 1.38V for a few seconds), but the average stays at 1.35V.
I ran Prime95 (26.6) with small FFTs and temperatures reached maximum from core0 to core3: 72°C - 70°C - 76°C - 74°C.
Am I safe with these settings, voltages, and temperatures? Or should I switch to TPU 1 at 4.5GHz?
It seems you're likely confusing the voltage readings between HWINFO and your motherboard. I'd rely on what your BIOS reports in external software. Since I'm not up to date with ASUS's newer BIOS versions, I can't provide specific guidance for your ASUS Z97-AR with an i5 4690K.

Temps remain stable thanks to the NH-D15, though the voltage stands significantly higher than usual based on reviews of similar CPUs. I've noticed reports of 5.0GHz with voltages lower than that. Anandtech, for instance, achieved 4.8GHz at just 1.26V using a Cooler Master Nepton 140XL AIO closed loop, which performs similarly to your NH-D15. Guru3D managed 4.8GHz at 1.29V with a Corsair H80i. You can find Anandtech's overclocking experience summary here:

Are you adjusting the Vcore manually, or are you relying on the motherboard to manage voltage via TPU? Most boards will supply more power than needed when handling overclocking. It's easy with a single click, but it doesn't offer the best performance, particularly at higher overclock levels.

The NH-D15 helps keep things stable, but the voltage is quite high compared to what I've noticed in reviews of similar CPUs. Some users have managed to get 5.0GHz with much lower voltages. Anandtech reported a 4.8GHz clock at just 1.26V using a specific cooler model, and Guru3D achieved 4.8GHz at 1.29V with another cooler.

Have you experimented with changing the Vcore manually, or are you relying entirely on the motherboard's voltage control via TPU? Usually, motherboards provide more power than needed when managing overclocking. It’s easy to adjust with a single click, but it doesn’t always deliver optimal results, particularly at higher overclock levels. TPU is handling the voltage, yet I’m having trouble getting stable performance and sometimes the core temperature readings don’t match expectations. I’m not sure what to do next.
Begin slowly. Adjust the CPU voltage to offset mode, which will reduce it to idle levels such as 1.10v when not under load. Next, perform a random test using a multiplier of 43 and a Vcore of 1.125. If you encounter a blue screen or failure, increase the voltage by +0.005v each time until stability returns (values like 1.130, 1.135, 1.140). Once stable, fine-tune the voltage by ±0.0025 for optimal performance (values such as 1.1325, 1.1375, 1.1425).
Overclocking manually involves a lot of trial and error, and each chip behaves differently—this is why results vary, like Anandtech's 1.26v versus Guru3D's 1.29V at the same frequency. If your system runs smoothly at 4.3GHz with 1.125v, increase the multiplier to 44 and continue alternating between voltage and multiplier settings until you reach a balanced setting.
Your temperatures are within acceptable ranges, and keeping voltage below 1.40 is safe for the long term. I believe you can achieve similar results with less manual voltage adjustment. It seems your chip might need more effort to maintain stability at higher overclock levels.
Begin slowly. Initially adjust the CPU voltage to offset mode; it will reduce the voltage when idle, such as to 1.10v when not under load. Next, perform a random test using a multiplier of 43 and a Vcore of 1.125. If you encounter a blue screen or failure, increase the voltage by +0.005v each time until stability returns (values like 1.130, 1.135, etc.). Adjust the voltage by ±0.0025 for better balance (e.g., 1.1325, 1.1375, 1.1425).
Manual overclocking involves a lot of trial and error, as no two chips behave identically—this explains why Anandtech reports 1.26v while Guru3D shows 1.29V at the same frequency. If stability is achieved at 4.3GHz with 1.125v, increase the multiplier to 44 and alternate between voltage and multiplier settings until you reach a stable point.
Your temperatures are acceptable, and keeping voltage below 1.40 should be safe in the long run. I suggest trying less manual adjustment and relying more on automated settings. It seems your chip could handle similar overclocking with fewer manual changes.

That's probably a misread of voltage between HWINFO and your motherboard. I'd trust what your BIOS is saying in voltage over external software. I'm not familiar with the newer BIOSs of ASUS boards as I have a three year old i5 4690K running on an ASUS Z97-AR, so I can't give specific instructions.

Okay, thanks for help
