2012 MACBOOK PRO GPU PANIC PRO
It makes me wonder why Apple doesn't try to make their notebooks cooler.Īfter extensive testing, I also noticed the Macbook Pro tries quite hard at preventing the 80w wall. Because the bottom lid is off, the logic board is a much lower temperature, making power consumption much, much lower. Looking at the photo, the GK107 die is really tiny, making the low temperatures make sense. Temperatures never exceeded 60C (close to desktop temps) for the GPU, but capped at 82C for the CPU. Only GTA IV, ARMA 3, and probably other multi-threaded heavy games can push it the throttle-limit (80w) but the low temperatures make power consumption very low.
2012 MACBOOK PRO GPU PANIC 1080P
With the bottom lid off, I can run 1070/2995 MHz for the 650m and 3.4 GHz for the i7-3720QM without exceeding 70w power consumption at 1080p for nearly every game. The high GPU overclock allowed me to have a consistent 40+fps at 1680x1050 with high settings. No way I could do such a high GPU overclock before doing the thermal paste replacement I just find that ridiculous, as it would hit 95C (throttling point for GPU) at lower clocks before. I'd like to point out, that the fan speeds are at 6000RPM for each fan, making it a little loud but not unbearable. CPU temperatures were high, peaking at 92C but the GPU never exceeded 80C! This was with the bottom lid on, playing on the Mac's display. I could run the game at 3.1 GHz and 1070/2250 MHz without hitting any throttling (80w limit). GTA IV was a good test for this, as it stresses all 8 threads on the CPU, and stresses the GPU. The high temperatures made the 80w limit a common issue. The big problem for me was the 80w throttle limit Apple has for the Macbook Pro. Power consumption lowered about 2-5w per component because of the lowered temperatures enabling me to have maximum cpu turbo/gpu overclock with the bottom lid on for many games! For Intel Burn Test, I saw the CPU no longer hitting 105C and throttling 3.4 GHz at 8 threads but instead capped at 95-96!
2012 MACBOOK PRO GPU PANIC DRIVER
Before replacing the thermal paste, I could only go up to 1050 MHz before the driver crashing. In many games, the GT 650M exceeded no more than 85C at 1070 MHz core, and 2995 MHz memory! The thermal paste added stability making me go up to 1100 MHz on core speed before crashing. I got a consistent 10C decrease of temperatures from the i7-3720QM, but the GPU gains I got were phenomenal. Before scraping off the original paste, I noticed I saw bare die on the CPU and GPU! I was hoping for around a 10C decrease per component, but after stress testing I was amazed by the improvements primarily the GPU. This was after a quick cleaning near the end of the cleaning process.
