Check if running 7 7700hq turbo all cores at 3.8ghz is feasible.
Hi, I was wondering if it's possible to turbo all cores on your i7 7700hq at 3.8ghz. I understand the risks and have enough thermal capacity. I tried using throttle stop by limiting the turbo ratio to 38, but it didn't work—still only turboing all four cores at 3.4ghz. Could you help explain why? Also, are there other ways to achieve this if you know? Thanks! I have a Lenovo Legion Y520 with a GTX 1050 Ti and 16GB RAM (I don’t have an image ready). Please let me know!
To the extent the motherboard/bios permits, the options are minimal. It doesn't depend on WHAT YOU DESIRE, it's what the bios enables. There are no controls to activate all core turbo features; without a switch, nothing can be turned on. You may wish to travel extensively. Everyone might concur that traveling benefits humanity, but if you lack the ability to move, your desires become irrelevant. If crossing oceans requires walking on water, then your ambitions lose significance. When the bios prevents enabling full core locked turbo settings, your goals are similarly unimportant. 7700HQ is a CPU with LOCKED settings. The motherboard in your Lenovo Legion Y520 does NOT support overclocking.
I'm questioning your chances due to multiple reasons. Temperature, power restrictions, locked CPU core, and restricted BIOS motherboard are involved. I'll boost one core up to 3.8GH, two cores to 3.7GHz, three cores at 3.5GHz, and four cores at 3.4GHz. This adjustment helps prevent overheating, avoids battery damage from high power usage, and reduces thermal strain. Your device is already near its thermal limits. Overclocking won't provide significant benefits and may worsen heat problems. I recommend keeping it as is.
The focus is on understanding what you aim to achieve and what the laptop can actually support. The laptop prevents full performance boosts due to its protective measures against intentional damage. It operates under the assumption of the worst-case situation and refuses to proceed. Running Prime95 with AVX disabled will cause a complete CPU load, which would likely lead to overheating if the device cannot handle it.
To the extent the motherboard/bios permits, the options are very limited. What matters is what the bios actually enables. There aren’t any controls to activate full core turbo if there’s no corresponding switch—then nothing can be activated.
You may wish to travel extensively. It could be considered your right to explore the globe, and most people would agree it benefits humanity that you do. But if you lack the ability to walk on water to cross oceans, then your desires become irrelevant. If the bios doesn’t provide a way to enable all core turbo settings, then your ambitions are moot.
7700HQ is a CPU with locked settings. The motherboard in your Lenovo Legion Y520 does not support overclocking. The bios on that board is also locked and doesn’t allow overclocking. Throttle Stop has failed because the laptop won’t accept overclocking changes.
Desiring overclocking while being prevented from achieving it is fundamentally different. You can throttle all cores to 3.4GHz using Throttle Stop, which isn’t an overclock. You can restrict all cores to 2.6GHz, which also isn’t an overclock. However, you cannot set all cores to 3.8GHz because that would be an overclock.
As far as I understand, you might be able to undervolt the CPU to boost performance, which could improve frame rates, and you can overclock the GPU via Afterburner, but locking the CPU core is not possible.
