1. 1.35v is DDR3L, which is a low-voltage version and is supported by newer CPUs. DDR3L appeared with Haswell (fourth generation intelligent core processor) in 2013.

2. 1.5V is DDR3, which is the standard version. It is supported by the early CPU. It comes out earlier, and the power consumption and heating are higher. Some new motherboards can't support it.

3. The high-voltage memory module actually refers to the standard voltage. Since the low-voltage memory should be 1.5V lower than the standard voltage to ensure stable operation, the production of low-voltage memory requires higher quality. The higher the memory voltage when leaving the factory, the worse the memory quality, which is also one of the advantages of low-voltage memory. Therefore, the difference between high and low voltage memory modules is that low-voltage memory modules consume less power than high-voltage memory modules and are more environmentally friendly.

4. 1.35 is a low-voltage version of the memory. In terms of use, there is little difference. Technically, low-voltage is more advanced. Electronics are developed with lower and lower voltage, because it saves more power, but there is no obvious difference in terms of a single memory.
