Problems exporting in 4k

i having problems exporting project 4k.  have been messing different options week.  project 30 min long.  consists of still jpg images @ 3840x2160 , timelapse videos in mov format , same resolution.  basic cross fade transitions , fade black transitions.  no audio.  here main settings of have tried:

 

format:  quicktime

codec:  mpeg-4 video

width: 3,840

height: 2,160

 

tried various frame rates, bitrates, various options checked/unchecked such max render quality, max render depth etc.

 

the video crashes @ few % unknown error.  tried narrow down small 20 second clip , not repeatable results short sections export successfully.  example, export 0-10 second section , 10-20 seconds section separately not 20 seconds @ once.  after reading on forums, tried avi format no codec no success.  tried quicktime jpeg 2000 codec.  tried turning off autosave.

 

i have replicated results on second computer different hardware , windows rule out hardware issues such memory instability.

 

note have managed export entire project of 27 minutes @ 1280x720 in quicktime mpeg-4 format.  in 1080p attempts, project goes further before crashing, maybe 50% complete vs 1-2% on 4k mode.  i've kept eye on memory , system doesn't seem t

 

any ideas?

 

main system windows 10 64-bit, i7-4790k, xfx r9-290, 8 gb ddr3.

premier pro 9.0.2 (6) build.

 

also tried on second computer windows 8.1 on amd motherboard little a6 integrated graphics same results (although slower of course)

curious choice of amd gpu ... (sad seems) adobe programs play nicer nvidia cards still. have few questions ...

 

1) using exporting directly out of prpro or queuing on adobe media encoder?

 

2) if queuing, have watched little thumbnail/monitor window in lower left corner tracks frames being encoded? often, 1 can see frame encoding glitches on ... go frame in timeline & see "different" there elsewhere.
