Q: Dear all, Why is it that some memory modules have SPD but then not all laptops support them? Why have SPD when not all supports it. I'm not sure if the DDR RAM I just bought comes with SPD and whether my laptop supports it. Advice?
A: Because some vendors programmed the SPD into the module, and some didn't, to see if your laptop will support it, my advice to you would check with the company you bought your laptop at, and give them the specs, or whatever they ask you and see what type of RAM will work with your computer. And next time, find out what type of hardware/software your laptop will support before going out and purchasing something, will save you some money and time, I know this hasn't been much help but without your computer specs, it's all I can do, hope you get your problem fixed:)
