Hello, Just wondering why the capable data rate of my 5d3 goes down about 20-25mb/s when doing 60p in RAW.  on 1920x1080 24p its hovers around 85-90mb/s and records continuous NP.

When i set it to 60p it says my capable data rate is only about 70-75.. so i have to down scale to about 1500xXXX.. I was hoping that i could at least stay at 1600xXXX which looks to be a similar data rate as 1920x1080 24p.

Are there any other modulars or options i can apply to make the capable data rate the same as the 24p setting?

to clarify I'm not asking why 60 fps uses more mb/sec at 1920x1080.. I'm wondering why the camera says my cards data rate goes from 95mb/s to 70mb/sec when i switch from 24 to 60fps.

Thanks for the help.

Writing frames at 60fps slows down the writing process.  20-25 mb/s is way too slow, at what resolution did you get such poor speed?  70 to 85 is possible.
Turn all hacks and and Global draw off for maximum speed.
