[Discuss-gnuradio] uhd_sink samp rate(sps)

hello 

when i set the uhd_sink or uhd_source samp rate to 10M

i got that 

The hardware does not support the requested TX sample rate:

    Target sample rate:10.000000 MSps

    Actual sample rate: 8.000000 MSps

then i set it to other value,some of them is ok,some not,

i know that the max samp rate of e310 is not 8M

so i want to know what value is ok for the uhd_sink or uhd_source 

between the min to max samp rate. 

i do not find it on manual page,but i got this message.

thank you
