Pretty much swapping out R-15 is a gamble. Most of the problems are in the software but no one has really 100% figured out why some R-15's work well (I have one that is great), and some have lockups, black screen, etc... (I have one like that too).
My well working R-15 I have 43 SL's and about 50% space used and its just fine. Going much higher than 43 SL's and it starts acting up.
