Crucial is down right now for maintenance, but overall dual rank is better performing than single.
Thanks for the reply.I was thinking probably dual ram was the better option,but was unsure because read somewhere that it's better to have the two sticks the same rank,but can't seem to find anything in the manuals that tells me what rank the current ram is.
Anyway might take a chance on dual ram.Amazing that there's not a lot of info out there on this
Just to update on this. Went to dell website and looked at memory they were selling and they listed the ram as dual ram module for my laptop, of course they are selling at extortionist prices, but got fairly cheap module from crucial same specs
Yes,works flawlessly,but seen as it is recommended to get matching ram,If I were you I would get the single rank ram because at least for me,that is what is in there already.
I don't think it matters that much though.
