Easy guys.
Where those of us in the know, know, many folks that don't will make the mistake of buying something because it is cheap - not realizing that it isn't fast enough, needs the wrong voltage, or is just incompatible for no apparent reason...
Specs will follow, but for now rest assured that all the memory you need is coming with the device. After you get it, you can start experimenting to see if other parts work. The last thing we want to deal with is someone whining because they bought some memory on someone's recommendation and it just won't work.
Patience is a virtue. Coops require much...
This coop should run fast and those that got in should have everything soon enough.
