Optiplex 3040 only support low voltage DDR3L.  If you tried to install regular DDR3 ram, it is not supported.

GSTD38G appears to be regular DDR3

spec sheet:  2 Long DIMM slots; Non-ECC dual-channel 1600MHz DDR3L SDRAM, supports up to 16GB

Re: The Brand for new RAM is GIGASTONE 8GB DDR3 1600

again, these ram are not low voltage DDR3L.  therefore, they are not supported in 3040.
