Just pointed an R4 and S9 to the pool.  Excited to be back!  Let's get it team!    Ps. I've never updated the firmware on either rig.  Anyone recommend it?  I have heard the R4 will not hash as high, but will have less HW errors.  I have some research to do; don't want to clog up this thread with posts covered elsewhere...  Pss. This pools app on my iPhone is great!  I love the BLOCK SOLVED notifications.  Mine on!
