4GB DDR3 RAM but what type ECC or non ECC shipped wih the G1X51ET ?

I got a Z230 SFF (G1X51ET) with 8 GB DDR3 ram but don't know if it's ECC or none ECC.

What type does the G1X51ET contain, is it always the same type that gets shipped ?

Or how can I check that myselvess ?  Nothing found in the BIOS nor in Windows system.

Thanks,

Steve
