When seating the bottom RAM chip you may have to apply a little extra side force to get it to seat properly. I put in the new RAM and just got a beeping sound upon starting. I then put the old RAM back in and got the same result.
In the UK, site sponsor Flexx sells memory and other upgrades for this Mac mini. In Australia, site sponsor RamCity sells memory and other upgrades for this Mac mini. 
In Southeast Asia, site sponsor SimplyMac.sg sells memory and other upgrades for this Mac mini. Also see: Actual Max RAM of All G3 & Later Macs. I am seeing a lot of people upgrade their ram to 8GB or even 16GB in their 2012 mini. Right now I have the stock 4GB ram in my system, so far it works.
Here is the solution I found on the Apple discussion board. 'Take a small flat head screwdriver and after you put the memory in slot 0, put the screwdriver between the top of the mac mini and the memory then turn the screwdriver a little to exert pressure on the memory into the slot. Do it on both sides of the memory.' This worked for me. I always consult Crucial's memory configuration tool. For a late-2012 Mac mini, see. According to them, this Mac can go up to 16GB (2 SO-DIMMs of 8GB each).
The SO-DIMMs should be DDRL3L-1600 (DDR3L PC3L-12800, CL=11, unbuffered, non-ECC, DDR3L-1600, 1.35v) The SO-DIMMs you mentioned seem like they should be compatible (CL=10 should work fine in a computer that can accept CL=11). But I would only buy from a vendor that has a compatibility guarantee. If there's a problem, I would want to be able to return them for a refund.
More Info • • • was mostly the coming out party; an event with one major headliner. But that newborn product didn't enter ecosystem alone.
Amidst the flurry of announcements, there was one other wee hardware relative on hand ready to join in on the launch festivities: a refreshed. Addressing criticisms of, Apple added USB 3.0 ports, upgraded to third-generation Ivy Bridge Core processors and boosted the standard RAM allotment to 4GB (you can configure it with up to 16 gigs). Perhaps most interestingly, it's now offering a hybrid storage option, the so-called, which combines flash memory with a SATA HDD.
One quirk still remains, though: the product's demographic leanings. Just who is the Mac mini for? Is it the go-anywhere, portable desktop best integrated in yachts, airports, automobiles and living rooms? Or, with a starting price of $599, is it the perfect, low-cost migration assistant (pun intended) for consumers making the switch from a Windows desktop?
Follow on to see which hat this not-quite-an- wears best. Hardware Let's not beat around the bush here -- there's a reason Apple plays proud host to a: ridiculously gorgeous design. No matter your sworn brand allegiance, you'd be hard-pressed to deny the Mac mini's simple, refined build. It's the tech equivalent of an irresistibly cute baby; the kind of hardware that stops passers-by, prompting compliments. And we're not just saying that figuratively, either. Within our own office environment, we repeatedly entertained questions from nearby officemates who were intrigued by the design. So fill up the comments below with the inevitable accusations of fanboyism, but know that we know that you know that we're right.
