Hi I am wondering if Ifixit would have a guide on New 2012 IMac 27" and is this IMac support DDR3 1866 RAM. Could I buy an IMac 27" without fusion drive and buy a larger SSD to put it on from a third party? Will the fusion drive work that way? and also the hard drive will be replaceable for a larger one from third party too? Thanks for answering my question. Always support Ifixit Weijie
If you check in intel’s web site you will find out that you can upgrade ram only to 1600MHz. Also you can put larger SSD and larger HDD and still work perfectly.
I recently put 1866Mhz cl11 memory into my late 2012 iMac 27’’ i5. Works fine, just at 1600. KHX1866C11S3P1K2/8G Kingston memory
