I just set up my voltage on both sticks slightly above 1,5 V. Starting with 100 MHz until 200 MHz works fine.
At 225 MHz one works and one goes zombie after a short time.
At above 250 MHz I get this right after starting:

Is this a power issue? The voltage to set is the total string voltage, right?
I have a 30 W power supplied hub. That would be 6 A at 5 V. So three A per stick. The table on post#1 says 2.8 A at 1,5 V and 300 MHz. So it should be enough power, right?
