Avoid underflow and overflow for transmitting with 2 channels in USRP X310

Hey,

 

I have a USRP-X310 with 2 UBX-160 Daughterboards.

 

I want to transmit simultaneously from the 2 Daughterboards at the same time in 200MHz (one in RF A , the second is in RF B).

 

I'm using 2 different 10G Ethernet cables 

I'm using GNURadio. 

 

How we can avoid overflow and underflow in the USRP?  I get many "O" and "D".

 

I tried to use many discussions from the internet, but the problem proceeds.

 

Thanks for any advice.
