Diagnostic code- 4MEM/9/40000002: 0x794a2b90

So my computer has recently started to get really hot and I just noticed that sometimes the images burn on the screen So I decided to run the apple diagnostics test and when I finished it gave me this code 4MEM/9/40000002: 0x794a2b90 and it froze it took a total of 13 minutes running the test when it said approximately it would take a hour so just wondering what it could be sadly my computer is the mid 2012 retina display so I'm out of luck on apple support or repairs unless I pay. so if anybody knows I would appreciate it very much thank you 🙂

MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10.5)

That is an issue with the RAM in the MBP. Since the modules are soldered to the logic board, there is no user intervention possible. The sad fact is you should make an appointment at an Apple store genius bar and have them evaluate the MBP. The evaluation will be FREE. and any required repairs will not be free. Mention to the technician that you go that error message from the AHT.

Ciao.
