ION (2) boxes were sold with and without Nvidia gfx cards. The graphics are usually not the problem, but the low-end CPU, which has to do some crunching, is. The low end ARM boxes (RPi) also have a hard time using the network port at full speed. My personal approach: don't expect full PC performance from a small toy box (unless it is a NUC)

'Out of memory' could also mean a leak in the Kodi software.
Question: what size/resolution(s) are your pictures? Any samples you can upload to imgur.com?
