dear all,

 

Just did a hardware test on my iMac machine and the test revealed an ERROR with below code;

 

4MEM / 60 / 40000000: 0x8075f390

 

Can anyone advise what this ERROR code stands for??

 

Thanks in advance!

    Would appear that one of the memory chips, your machine should have

    four RAM chips, may be defective or non-standard.

     

    Maximum Memory    32 GB

    Memory Slots    4 - 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM

     

    • Install memory in an iMac - Apple Support

     

    If you upgraded the memory from original stock, you could revert to the

    as-shipped configuration to test.

     

    Good luck!

    great thanks mate! very much appreciated!

     

    I indeed upgraded the 4 RAM chips to 32GB however the system displays 32GB 1333MHz DDR3

    made a typo in my previous post as my iMac is from late 2012

     

    so I guess using non standard RAM chips is causing this problem to occur?

    That depends on which "non-standard RAM" you installed. Apple does not make RAM--they buy from established RAM manufacturers, commonly Samsung. Hynix, and Micron. Trusted third-party RAM vendors like Other World Computing ("OWC"--my first choice) or Crucial sell good RAM that will work in your Mac. All our Macs have RAM upgraded from OWC and we have never had an issue.

     

    Not all RAM is created equally. There are many reports here of people having trouble after installing PNY, Corsair, or Kingston "ValueRAM." The latter maker sells two grades of RAM with ValueRAM being the low-cost option. They make a standard level of RAM that works in Macs but is hard to find. The RAM business is so price-sensitive that resellers don't seem to carry the Kingston RAM that works in Macs. You can tell if you have Kingston Value RAM because the model number on the module will start with "KVR"

     

    So what brand did you install?
