Can't resolve the deadly 3 beeps on startup

Hello everyone,

I have a Mac Mini Unibody (mid 2011) which doesn't startup anymore. It was not in use for some time and when we got it out again it gave the 3 beep signal which would indicate my RAM does not pass a data integrity check. But my RAM does work in my other Mac which uses the same type of RAM.

I have searched for the ultimate solution on different message boards and executed several suggestions made there. I have done the following:

  • I have tried to reset the PRAM, but no succes.
  • I have hold down D during startup, but no succes.
  • I have checked the Logic board, but I can't find anything loose or broken.
  • I replaced the thermal past on the heatsink.
  • I cleaned my Mac with compressed air, but no change.

My question: Is there anything else I can try before putting the logic board in the oven? As this will be my last and final step.

Hope you have some suggestions!

Ditta

After some research I found that three beeps mean "No RAM banks passed memory testing", have you insured that all RAM cards are properly seated, and are in working order?

Yes, I have switched them around. I have used new ram cards (which are now in my iMac working just fine). I have reseated them, and tried both banks separate.

So as i mentioned, I don't think it is the RAM cards or the way they are seated.

What speed are the RAM modules?

Your Mac mini might not support modules you have. I would try 1333 MHz modules then see if you have any luck with them.
