iMac Late 2012 - 2,9Ghz core i5 - proposed memory doesn't work.

Hello,

 

I've just bought 32GB (2 x 2 x 8Gb) memory following the compatibility instruction.

And it doesn't work, the iMac beeps at startup. I tried every slot and every memory stick.

the delivered memory is CT2C8G3S160BMCEU, DDR3L - 1600 SODIMM (1,35V CL11).

 

What do I wrong?

 

thanks for the hint.
