Overclock help for laptop i7-7820HK
Hello, I'm searching for a gaming laptop with solid cooling performance and an I7-7820HK processor paired with a GTX 1070. I'm considering models that allow overclocking from 2.9GHz to 4.2GHz, such as the Alienware 15 R3, Sager Np8157, and clevo p650rs. The Alienware stands out for its slim design, but I need information on temperatures. Any recommendations from MSI or Asus would be helpful. Thanks!
I don't suggest overclocking any laptop because they tend to cause overheating problems. Alienware is just a rebranded Dell, and I haven't used one since Dell acquired them, but I think the BIOS might be locked and won't allow you to change it.
I own an older MSI GT60-2od with an i7-4800MQ 2.7Ghz boosted to 3.7Ghz using a 780m, while I can easily overclock this one if needed. If you're looking for something for gaming, the thinner the model, the worse your cooling options will be.

overclocking isn't possible on laptops because their design restricts it. But why would makers add overclockable chips?
Avoid using laptops without OC. I have an HP i5200u (2.2ghz to 2.7ghz) with Nvidia 950m, and I know standard cooling isn't always enough if I'm not close to a fan or in the air conditioner. The ideal setup would be one where the regular clocks are sufficient.

laptops aren't designed for overclocking because the casing is too small. Yet manufacturers add overclockable CPUs for reasons. Just because an unlocked CPU is in a laptop doesn't guarantee it will work. Dell's alien ware still has locked BIOS even with unlocked CPUs.
I can't believe how many answers there are. Of course you can change things yourself.
I usually make small changes and adjust the voltage a bit lower.
The outcome is: improved performance, cooler temps, and longer battery life.
I switched from a 17 R3 to a 17 R4. I don’t know much about the R4 yet, but I remember my old R3’s CPU and GPU fan speeds, stable undervolts, etc. It’s worth experimenting with

I’m sharing this just to correct any misunderstandings. If anyone researching their next laptop encounters this, I aim to clarify a few points. Claims that you can’t overclock a laptop CPU are outdated. In earlier models this was accurate, but modern laptops have improved significantly. Pascal delivers desktop-level performance in compact form factors, and Intel’s newest CPUs offer comparable results. I once owned an MSI GTX 1070 (mobile) paired with an i7-6820hk. I kept the CPU at 4.3ghz across all four cores and the GPU at 1950mhz. Both maintained temperatures between 65-70°C thanks to a custom fan curve. This was my first time attempting an OC on that specific CPU, and I might have pushed it further, but I didn’t feel the need. Of course, this laptop was large with top-notch cooling. Later, upgrading to an Alienware 17r4 with i7-7820hk and GTX 1080 gave me a similar outcome. I believe the temperatures were slightly higher because of a better OC setup and a more powerful GPU (4.4ghz and 1080). Please share this information so others know the truth. I’m tired of hearing that laptops can’t be overclocked.
