Re: Slow P1

So, you are also using the P1 power brick plugged into the P1 in conjunction with this TB3 dock correct?

Re: Slow P1

No. The power goes to the dock, and the thunderbolt connects the dock to the computer.

New development, all my screens were resizing and flickering. It's the dock. The rating on this stock is extremely poor. More one-star ratings than five-star ratings.When I direct, connect all ports to the computer, then everything is fine with the CPU running at 4.25 MHz. The dock is defective.

Best regards,

Re: Slow P1

You need to connect the P1 power supply in addition to the TB3 connection. The TB3 cannot supply power to the P1 through the USB-C. The system needs more power than can be provided through that connector.

Re: Slow P1

The need for the dock is diminishing quickly.

Re: Slow P1

The P1 should be connected to the TB3 Workstation Dock which will supply the correct power/signal combination.

Re: Slow P1

The computer connects to the dock via Thunderbolt. If that doesn't work then the doc is defective.

Re: Slow P1

The P1 will not charge via the USB-C port while it is on due to the limitations of the port and will, therefore, be running on the internal battery. The TB3 Workstation Dock adds a power connection in a combined cable to the power port and USB-C port on the left side of the system. That dock also comes with two power bricks (65W for the TB3, 230W for the laptop via the combined cable). I'm not sure how the orginal TB3 dock performs if there is no power to the P1, but it could be running with insufficient voltage in that scenario. Your dock may or may not be defective, but I had suggested that you plug in the P1 135W power brick in addition to the USB-C cable and see if things operate properly for your configuration. The only thing that the TB3 Workstation dock adds is the convenience of plugging in power and signal in one operation. There's no other advantage over the Gen 2 TB3.
