New RAM Issue. Loud beeps and restart.

[stonemann]

A few days ago I decided to install additional RAM for my 2010 iMac. I bought 2x2gb OWC ram modules and installed them in the two free lower slots. On start up everything worked fine, computer recognises the modules and runs fine.

Except once a day during normal operation there are several really loud beeps then the computer will shut down and restart itself. Everything then works fine for several hours until the next time.

I checked that the modules are seated correctly. They are. Ran a memory diagnostic test. All okay.

I‘m really not sure what’s going on. Or what to do next. Any thoughts appreciated.

It sound like your new RAM, or the RAM slots, may be defective.

"I‘m really not sure what’s going on."

The RAM is defective or otherwise incompatible.

"Or what to do next. Any thoughts appreciated."

a. Take it out
b. Put the original RAM back in
c. Send it back for refund
d. Buy RAM from this place:

Thanks for the replies. Have taken out the new RAM, cleaned out the slots as it was pretty dusty. And reinserted in different slots alongside old RAM to see if that makes a difference. New RAM is still recognised and running okay. Will see if the situation lasts as these shut downs have been pretty random since the upgrade.

That happened to me when I put in some extra ram into my old 21.5 inch 2010 imac... I took the ram out and put it back in and it has not done it since (knock on wood*)...
