Hey guys, I have one M378B1G73EB0-YK0 Samsung 8GB PC3-12800 DDR3-1600MHz non-ECC Unbuffered CL11 240-Pin DIMM 1.35V Low Voltage Dual Rank Memory Module I have some spare 1.5V Micron sticks, one 8GB and one 4GB.  So was thinking of using these side by side.  Or what would happen if I ran the 8GB 1.35 Samsung that is in there now and one 8GB 1.5V Micron?  I researched it and it seems it may work on some MB's.  I could not find out any details about the MB, and if it is rated to work with 1.5V? I will dig some more to see if I have another matching Samsung chip
Can I run 1.5V DRAM
