Traditionally yes, but the newer series of R10s seem ok with the HyperX Fury ram too, possibly even more so than the older original R10 boards.
I didn't let it sink in after many of the issues surrounding adding ram to my R10.  Purchased the 16GB HyperX Furry Black 16GM 3200MHz DDR4 thinking it would be a match to the Dell OEM X3MCJ 16GB in my system.  Nope! Not a match with different timings. I just received a price for OLOy Blade 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3600 (PC4 28800).  Has anyone used the OLOy brand in their R10?  Any discussion on the functionality and stability of this specific RAM in the R10? Any help would be appreciated.  
Aurora R10, Oloy RAM?
