Remember you also make the system less stable when you lower the power as well."
2015 MACBOOK PRO PROCESSOR SERIES
Basically, you are only reducing the phase from three to two and that’s as far as the firmware will let you in this series using the Volta app. "Lowering the number of phases reduces the power to the CPU but at a cost! It is designed to lower the systems power draw in idle states (not while crunching any work loads). Even still I’m mostly buying it for its screen and keyboard, not as much for its CPU performance. I tend to wait a good year before jumping to a new design. the newest 2019 16” system is what I have my eye on for this fall.
Maybe you need to look at getting a newer system. I currently have a 6 core 2013 system and even it struggles with 64 GB of RAM and a 2TB blade SSD which is mostly empty at times. I work on very large images which my MacBook Pro’s just can’t deal with when I stitch the discreet pictures together (30 to 90 images). I use TG Pro as I find its the best tool allowing me see whats running hot and I can set a thermal point to pump up the fans (turbo).Īs good as this system is (I have two!) It just can’t perform as well as a desktop which has better cooling. I think this is a waste of effort and the gains are so small its really not worth the data’s integrity.īe cool man! A better approach is to improve the systems cooling. Remember you also make the system less stable when you lower the power as well.

2015 MACBOOK PRO PROCESSOR INSTALL
The next issue depends on which model you have: If you have the dedicated GPU model (DG) then I would install gfxCardStatus to disable the discreet GPU by using the integrated graphics engine only.Īs far as altering the CPU’s voltage the app is not really able to do to much here as in this series the circuit is setup in a three phase design. I also make sure the heatsink fins are clear of dust as well as the fan blades (the cleaner the system the better it can stay cool). I use either Arctic Silver 5 or Grizzly Kryonaut thermal paste. The next issue is the CPU and GPU’s: I would clean off the old thermal paste and apply a good nonconductive paste. I also recommend getting as large a drive you can get as the bigger drives are not only faster they also run cooler! The less space the drive has the more it needs to engage wear leveling which pushes both the CPU and drive harder (heat). I strongly recommend having no less than 1/4 of the drive empty (500 GB and larger) and 1/3 for smaller drives.
That leads us to how big is the SSD drive and how empty it is. Let’s start with RAM: There is a limit on what you can do here as this series has soldered RAM so you can’t get beyond what you currently have (hopefully 16 GB) so the OS uses virtual RAM which is leveraging the drive for what ever it needs to make up for the lack of physical RAM. You are fighting two elements! Heat and performance! These often are polar opposites, as you get less heat with less performance or as you have discovered to gain performance you need to deal with the heat it creates.
