I’m looking to get a RAM upgrade for my SONY VAIO VPCEH25FM. If I get DDR4, is it compatible with a DDR3 slot? Have you checked the manual?

Does it say that DDR4 is supported? No, DDR3 and DDR4 are not cross compatible.

The physical sockets are different among other things like input voltage, pin count, etc. See the picture below for a full size DIMM, which would be similar to a SODIMM. For nyxee’s question, DDR3L is different from DDR3 and DDR4 as it can work on a voltage range. The DDR3L RAM consumes lesser voltage compared to the DDR3.

DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1. 5v only while DDR4 consumes 1. DDR3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector. For more information go through this link.
