I'm looking to get a RAM upgrade for my SONY VAIO VPCEH25FM. If I get DDR4, is it compatible with a DDR3 slot?

2how does DDR3L factor in? how does it compare with DDR3 and DDR4? – nyxee – 2017-01-08T22:44:07.580

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 and 1.35V.DDR3 works on 1.5v only while DDR4 consumes 1.2v only.DDR3 RAM uses a 240-pin connector, while DDR4 RAM uses a 288-pin connector.

They say it's different slots
1Have you checked the manual? Does it say that DDR4 is supported? – gronostaj – 2015-08-03T21:26:03.657
No, I got it 3 years ago and I threw away the manual immediately – Jacky Xie – 2015-08-03T22:36:36.683
