F3-12800CL9D-8GBSR1 (light grey) vs F3-12800CL9D-8GBSR2 (black)

SR is 1.5v SR2 is 1.25v, an SR1 (newest version?) is 1.35v

Are these all the same chips just with a different stock SPD voltage, or is there anything more to it?

Dear Customer

The color is all the same. It may be the lighting that made them seem light grey.

The chips used are different, that's why DRAM Voltage is different. This is the main difference between the modules.

Thank you

Alright, so I'll just get the lowest voltage ones, I guess, prices are the same.
