I have an iMac 27", Mid 2010 (11,3 model), "Core i7" 2.93 GHz. 4*2GB installed RAM..Plan to upgrade. Any thoughts, experience if 4 * 8 GB would work if upgraded to or is 16GB with 4*4GB max I can reach? Thank you

  • Mactracker app is useful for this.

According to everymac.com, the answer is a maximum of 4x8GB=32GB.

Crucial will sell you 2x8GB for $103.99.

OWC will sell you 1x8GB for $39.99 or 4x8GB for $159.99.

  • it is i7. And below is sytem report of memory.. So I assume it can go up to 32GB... Any comment? Tnks Model Name: iMac Model Identifier: iMac11,3 Processor Name: Intel Core i7 Processor Speed: 2,93 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 8 MB Memory: 8 GB Boot ROM Version: SMC Version (system): 1.59f2 May 11, 2019 at 11:59
  • So, if you check Mactracker, then 32GB, but Apple says a maximum of 16GB - always Apple gives a lower limit.

  • Sometimes the larger memory does not exist at the time computer is manufactured. When a larger size becomes available Apple does not update its documentation. Apple has solved this problem by not letting you add memory in many of the latest models. May 11, 2019 at 12:26
