This action is to change back 1500 to 1472 MHz.Ĥ. Go to Frequency section in More Power Tool and change the Memory DPM 3 (MHz) from 750 to 736 then press'write SPPT' and restart. Solution: When using More Power Tool following his step to unlock WattMan in the AMD Control Centre(Apply all the tick to enable WattMan) and before pressing the 'write SPPT' However, this wasn't the cause of the flickering or bug but still shouldn't set that high even undervolted, due to the power limited.Ĭause of Flickering after undervolt: The cause of flickering is due to More Power Tool automatically overclocked the Memory clock from 1472mhz to 1500mhz. However based on the vbios dumping directly from GPU-Z and translated in More power Tool, it appears the boost speed default are now setting to 1450mhz. The default boost clock speed for Radeon pro 5500m in macbook pro 16 is only 1300mhz, so by default it will never exceed 1300mhz with/without undervolt. (This is what i experience and for some other ppl/ You can read other comment in his post) Cause of the flickering using More Power Toolīasically by dumping the vbios from GPU-Z to the More power tool, the clock and memory frequency were not the same as default frequency(1472MHz < 1500MHz) which leading to flickering issue for some person. However, somethings should be corrected under the More power Tool before write SPPT.ģ. In his guide, he found a way to undervolt the GPU to achieve higher clock speed at the same power budget (50w). Refer to Automatically undervolt in Bootcamp by u/Randomhkkid I have liquid metal the CPU and GPU, and also applied the VRM thermal pad mod.Ģ. I can say that Intel CPU might be power hungry and hot but the power deliver design from apple was purposely insufficient.

I feel like they just want ppl to believe it was the fault of Intel CPU. However this laptop is very power (VRM) limited in the inside both the CPU and GPU. Macbook pro is the first Mac I owned, I can say I absolutely love the exterior design, and the speaker are unlike any windows based laptop. I am a Civil Engineer based in Hong Kong and a PC enthusiast (custom loop/overclock).
