This offers a greater number of settings on the motherboard, as well as other improvements, such as using a mouse to navigate its menus. With it, you can access all of the code behind your motherboard's image in hexadecimal, as well as make modifications to it.Īlthough motherboard images are commonly called BIOS, most computers today use UEFI, which stands for Unified Extensible Firmware Interface. I've reset SMC and NVRAM *many* times.UEFITool is a program for viewing and editing BIOS and UEFI installation files. Would love to understand why PFM001 is happening.Again, all seems to be working fine: shutdown, boot, standby, fan control, etc.When using the Intel 760p (or others I tried: Crucial 500, Adata SX8200, HP EX920), booting into diagnostics usually, but not always, gives me the PFM001 error.Though I experienced no troubles to warrant running diagnostics, I ran them anyway.PFM001 - There may be an issue with the System Management Controller (SMC).Typical system temp (cpu cores/peci) - 33C / 41C.Machine idling during charge while plugged into power (battery around 50%).Typical system temp (cpu cores/peci) - 45C / 56C.Screen brightness set down around 3 out of the 16 block scale (low). Test starting w/ fully charged battery, continual stream from Netflix via Safari (constant video and wifi activity) plus loop of movie playing via VLC locally from SSD (constant video and read from SSD).Info collected below: Apple SSD / Intel 760p other than fit, both appeared to work just fine.short 'B' adapter fit much better without the pressure on the case.long 'C' adapter worked just fine, but I didn't like how the case was closing.MacBook Pro (Retina, 13-inch, Early 2015).Also appreciate any feedback / insight on this setup. I can't swear the numbers are accurate, but they should be a fair relative comparison between the two SSDs. The following are very *non-scientific* results.

Just contributing my experience if it helps anybody else. I settled on the Intel 760p hoping for lower power consumption and full user capacity (as opposed to giving up 32gb w/the Adata SX8200 480gb stick). Truth is, I would probably have preferred an Apple 512gb SSD and been happy with it if I could have found the right price and some faith that it wasn't already worn out. I wanted to expand capacity while keeping power consumption and heat as low as possible. I was happy enough with the Apple SSD performance, especially being limited to PCIe 2.x on my machine. Thanks for all the help in this very informative thread.
