This is a game changer (literally). Something I have been trying to get on all the Apollo Lakes after testing the Tbook Air/ Civiltop air with no power limits. It has a huge difference in Intel HD 500 GPU performance. I discovered it was like the Core M’s when the power limits are increased or even disabled the Intel 500 / 505 integrated GPU it can finally stretch its legs so to speak and hit its maximum 700Mhz/750Mhz GPU boost speed and keep holding it without power limits or higher limits. In turn increasing performance dramatically, for example, it’s the difference between running Counter Strike Global Offensive 800 x 600 low settings from 30-35 FPS with a stock TDP of 6Watts to 60-70Fps  with a tweaked TDP 10W limit. The whole reason the Civiltop Air and Tbook Air were so much faster is in the bios the power limit in CPU advanced settings was off. No limit means it can use all the power it wants, it also means it will use more power and generate more heat. As a result of this, I only recommend this tweak to those laptops and tablets that have copper heatsinks. And better yet have full metal builds to better dissipate heat. This is a must! Otherwise, you will hit thermal throttling triggering Tjunction max so clocks will drop and worse case scenario the tablet/laptop could power off or go into sleep mod to stop any damage. The following laptops, tablets I have opened & confirmed to have copper heatsinks. Chuwi Lapbook SE Jumper EZbook X4 Jumper EZbook 3 Pro series Jumper EZPad 6S Onda Xiaoma 21/31 Tbook4 Tbook Air Civiltop Air Cube iwork5X This mod is not recommended on the: Chuwi Lapbook 14.1 first batches (No copper heatsink) Lapbook 12.3 (No copper heatsink, just tin shielding) Borderline: EZPad 6S  – It has a copper heatsink, but plastic housing results in less heat dissipation EZbook 3S – It has a copper heatsink, but plastic housing results in less heat dissipation To further improve thermals, you can also add a thermal pad between the copper heatsink and rear metal housing. So here is the tweak: It involves running RW – Read write everything and editing the memory to change the TDP Limit set in the bios. Unfortunately, there is no bios level tweak for this yet, that would require editing the bios and flashing it with an unlocked power limit setting. Something that is beyond me and bios editors I’ve tried doesn’t seem to allow it. It’s also high risk. DOWNLOAD/LINK: This method is just editing the memory. Many thanks to Joe, the Apollo TDP unlocking/tweak thread is here. I will have a video soon with how to do it and the result it can achieve which is well worth it, the performance boost is mostly for the GPU as the CPU is already running at top speeds. But now it will hold those speeds. So it will improve the CPU performance a little. I also expect the N4200 to have the greatest result with this mod as it has the 300Mhz higher CPU clocks and 50Mhz higher GPU turbo clock with 6 more EU’s. >WARNING< Apply this tweak at your own risk. I’m not responsible for bricked devices, burnt out CPU’s, thermal meltdown, burning your house down or increased headshots in CSGO from better FPS. Watch your GPU and CPU temps closely with HWinfo, if it gets too hot, stop gaming, use sleep or reboot to put the stock TDP back into place. So there we go, now all Apollo Lakes can performance equally!
