You must promote words
You do down your that memory
Attained buys the memory the place he to know
Will give you that match
However the memory promotes now words
Paramount consideration 1G
You buy single scroll 1G the independence to use
Do not use that 256
Such do not manage any model
You might sell as for that 256 memories it or give the friend
Because you have bought the 1G words
Inserts this again 256 also does not have any effect
1G general idea more than 130
