iFixit RAM upgrade not compatible?

Just purchased a “MacBook Pro 13" Unibody (Mid 2010) Memory Maxxer RAM Upgrade Kit”. but the new RAM doesn’t work. I’m running OS 10.12 and my laptop matches all other required specs. I’ve never experienced RAM compatiblity issues with iFixit in the past, but that was before they started selling “iFixit brand” memory, so maybe things have changed.

I’ve tried the following:

  • re-seated new RAM, no effect
  • tried both new chips separately in each slot to make sure chips and/or slots weren’t defective
  • reinstalled old RAM, laptop works fine
  • repeated all of the above 2 times, same results (I had to be certain, since I spent $41 non-refundable bucks for overnight delivery!)

Any other ideas?

Answer this question I have this problem too

Your Best Bet Would To Be To Talk To Ifixit Staff About That. They May Have Messed Up Your Order And Sent You Ram From A Different Model.

I double-checked the chips before install, and they both seem like the correct ones: 8GB DDR3 PC3-8500 1066 MHz

You may have either bought the wrong product or the wrong product may have been shipped to you. You may want to contact customer support at help.ifixit.com about this matter as they can assist you with either a return or exchange.

What is the OS version you are running? You may need to update the EFI firmware.
