Issues After RAM upgrade

[JWarrenJackson]

I dropped 16GB of RAM into my late 2012 iMac. After the upgrade, the boosts in speeds have been awesome. BUT, upon start up, it takes about 10 min for the mouse and keyboard to start working. The mac shows them connected and paired. I'm able to remote operate my mac from my phone. Taking the place of the mouse and keyboard till that **** starts working.

Suggestions? The mac recognizes the RAM. Reads all 16GB. Everything is great after the 10-15 min but obviously something is wrong. Haven't been able to find much. Heard of flashing the RAM. Doing some kinda reset. Don't wanna give it a shot till I hear some other suggestions.

THANKS IN ADVANCE!!!

It's a good idea to reset the SMC and the PRAM after installation of new RAM...:

If that fails to correct the issue, you might have a faulty stick in your Mac

Nope, still the same problem. Took 8 min this time.

well, you could try your stock ram again just to verify that it is in fact the ram that's doing this (it seems fairly bizarre that ram would cause this problem and not others)

other than that, i'd be screwing with bluetooth settings in system preferences > bluetooth, removing the devices, trashing the bluetooth plists, rebooting, readding them yadda yadda

you can put the old back if problem goes the ram has an issue.^

here is a download to test your ram

do all ram and 2 passes. it takes a few hours. this is a decent but not perfect way to test your ram. it will test about 90-95% of each stick. if you pass this test there is another ram test program that is better but you need to burn a cd/.dvd and the the 2012 mini does not come with a cd/dvd player


oh do you have corsair ram?

corsair seems to have the most problems. still works around 90% or more sticks are good. oh to run the rember program you need to go to security in preferences and click the box anywhere for downloads see thumbnail

try 2.4 ghz wireless mouse instead of bluetooth

As others suggested the proper course of action is to remove the new 16 gbytes of ram and install the ram that shipped with your mini. If your problem is fixed the 16 gb ram is either faulty or it wasn't properly seated in the mini.

If the problem still exists after you put the original ram back in you know the 16 gb ram is good and you have another issue that will require further looking into. If this is the case your machine is still under warrantee and if you can't fix the problem you can have apple fix it.
