ECC memory on Z68 Chipset + Xeon

Bonjour,


It’s more a request for information than a modification, the motherboard of my iMac has a Z68 chipset + Xeon, I tried an ECC strip, only it is not seen (error beeps as if there were no memory), with another one in the same bank non ECC error beeps and no ECC bars in the second bank next to it and only it is not seen by the system.

My question is simple, like on a “real” server that has to put peers in ECC?

Or is it mandatory to modify the UEFI/BIOS?

I know that the interest of my ECC memory in my machine is almost null, it’s just for my curiosity.

Thank you for your time.
