5D mkIII - RAW video 2fps override Timelapse issues

[spphoto]

Hey all,

I've taken to shooting timelapses with ML RAW video on my mk3 woth the 1-2fps override function. Just to save the shutter I'm at 450,000 actuations already!

I can't seem to get a frame size bigger than 1920x1080 with super fast cards

message says,
2880 not possible in current video mode (max 1920)
Write speed needed: 86.4mb/s at 25.000 fps.

Just wondering if there is a trick I'm missing

Thanks

S
