Description One Dock V2 External Graphics Dock Support for ThunderBolt/OCulink
eGPU for SuperBuy User Only
Description:
One Dock V2 is a 2nd generation graphics dock developed by the
collaboration of the "Ultra-portable Device Community" QQ group.
One Dock is the first docking station that provides both Thunderbolt and
OCulink interfaces.
The design goal of One Dock is: occupy the smallest desktop space, show the
graphics card's own aesthetics.
One Dock does not limit the type of PC host and does not limit the size and
power (TGP) of the graphics card.
When users use Thunderbolt/USB4 interface to connect to One Dock V2, it can
provide up to 96W of reverse power supply to the host computer.
When users use the OCulink interface to connect to One Dock, they can get
PCIE 4.0 4X with a maximum bandwidth of 64Gbps, which greatly reduces the
performance loss of the external graphics card.
Precaution:
The One Dock shipment package does not include any personalized
accessories, users need to provide their own graphics card, Thunderbolt/OCulink
cable and power supply.
Before any disassembly operation, please ensure that the power has been
disconnected, and discharge the human body static electricity in advance.
Thunderbolt Cable Option:
Currently, only Intel Thunderbolt 4 certified Thunderbolt 4 active cables
are recommended.
For the list, please refer to the Intel Thunderbolt Certified Products
website.
The difference between the active cable and the passive cable is that the
passive cable only has an E-Marker chip, the E-Marker chip can only report to
the host the applicable PD power supply gear and the communication protocol
supported by the cable, while the active cable has an additional retimer chip
than the passive cable, the retimer can ensure the integrity of the signal
transmitted over long distances.
OCulink Cable Option:
Any quality-qualified OCulink 4i cable can be used theoretically, but since
the quality of OCulink cables on the market varies, it is recommended to choose
them from the photo album "Accessory Purchase Address" in group, which are
specially customized for graphics docking applications.
The vast majority of OCulink graphics docking failures, such as not
recognizing the graphics card, insufficient bandwidth, blue screen in use and
other problems, most of them are caused by the cables, which can usually be
solved by replacing the cables.
Power Supply Option:
One Dock V2 supports two types of power supply, the power supply power
should be greater than the sum of the TGP of the graphics card and PD reverse
power supply power, and then leave a margin of 15-20% to cope with sudden
transient power demand.
20V GaN Power Supply:
Any power supply using the DC7450 connector (i.e. DELL notebook power
connector) with a maximum power of 330W can be used.
When using the 20V power supply, One Dock V2 supports graphics cards with a
maximum TGP of no more than 240W. Support 20V GaN power supply is for
portability, more than 200W TGP graphics cards, are 2 or 3 fans of large size
graphics cards, no longer portable, so there is this power limit.
When using 20V power supply, the 5557 connector on the One Dock V2 is the
power output connector, you can use the 5557 to PCIE 8-pin power cable included
in the package to connect to the external power supply connector of the
graphics card.
12V ATX Power Supply (including ATX, SFX, FLEX and other ATX compliant PC
power supplies)
Any graphics card can be powered directly by an ATX power supply. The CPU
8-pin connector of the power supply is connected to the 5557 connector of the
One Dock through the short 8-pin adapter cable included in the package. The
graphics card's external power connector connects directly to the ATX power
supply.
There is no restriction on the TGP of the graphics card.
Note: When using an ATX power supply, a 24-pin boot jumper as shown below
must be used to connect to the 24-pin connector of the ATX power supply to boot
up the power supply.
Instruction for Use:
Connect PC via Thunderbolt Interface:
If necessary) Graphics card bracket installation: Use the included wrench
to fix the graphics card bracket with a M3*6 flat head screw at the screw hole
on the side of the PCIE slot end.
In the top cover of One Dock, where it is in contact with the bottom
surface of the graphics card cooler, evenly affix 1-3 grains of the included
silicone cushioning particles to avoid bumping during use.
The graphics card PCIE gold finger aligned with the PCIE slot inserted.
Note: The installation must be aligned with the gold finger and slot,
otherwise the downward operation may cause irreversible damage to the graphics
card or One Dock.
If necessary) Use the chassis screws and nut set to fix the graphics card
PCIE bezel on the graphics card bracket.
Connect the power supply correctly by referring to the power supply
connection method given in (3) Power Supply Option.
Connect one end of the Thunderbolt cable to the upstream Thunderbolt port
with the laptop logo on the back of One Dock, and another end to the
Thunderbolt 3, Thunderbolt 4, or USB 4 port of the PC host.
From the graphics card chip official website download official driver,
according to the driver software prompts to correctly install and restart the
computer.
Installation is complete, the graphics dock can be used normally.
If you want to disconnect One Dock from the PC host Thunderbolt/USB4
connector, you should first quit all the running games or other applications
that are using the graphics card, pop up the graphics dock in the taskbar, and
then unplug the Thunderbolt cable from the PC.
Connect PC via OCulink Interface:
IMPORTANT NOTE) If your PC/laptop requires the PERST#/CLKRUN# delay (or
RTD/CTD delay) feature for compatibility when using an external PCIE device, do
not purchase the current version of One Dock. This feature will be added in the
next version.
This method has a higher threshold than the Thunderbolt interface, and is
only recommended for users who have the relevant knowledge; general users are
recommended to use the Thunderbolt interface to connect the graphics dock.
Completely turn off the PC and unplug the power.
Refer to the steps in (1) Connect PC via Thunderbolt Interface to install
the graphics card correctly into the PCIE slot of One Dock (including the
external power supply cable of the graphics card correctly connected).
If the PC host does not have a native OCulink connector, you need to
install an M.2 to OCulink adapter board (or desktop PCIE to OCulink adapter
card).
Connect two ends of OCulink cable to the OCulink port of PC and One Dock
respectively.
One Dock first power on, and then start the PC.
PC boot, check the device manager to find new graphics device, install
graphics driver, graphics device should be able to be seen in the device
manager and no error, but at this time is not yet available and there is no
graphics driver icon in the taskbar.
Use GPU-Z to view the external graphics card, most of the functions at the
bottom of the window are not checked, at this time the graphics card has not
been properly driven, and can not be used yet.
Reboot the PC, and check the external graphics device in the device
manager. If it is an Nvidia graphics card, a 43 error will be found on the
graphics device details page. Refer to the Troubleshooting chapter, use the
Nvidia error 43 fixer to fix it.
After fixing, the graphics device 43 error in the device manager is
eliminated and the graphics dock can be used normally without rebooting. AMD
graphics cards do not have this step and can be used after a reboot.
Use GPU-Z to check the graphics card properties, all parameters are normal,
all functions are checked; use AIDA64 or CUDA-Z to test the bandwidth is
normal; Furmark can run smoothly. So far the graphics card has been correctly
driven and can be used normally.
If you still can't use the card properly after the above steps, you can
uninstall the graphics card in the device manager, check "Try to remove the
driver for this device", reboot, and repeat steps 1-8. If you still can't use
the card properly, consider replacing the OCulilnk cable and repeat the above
steps again. most of the hardware problems encountered in OCulink docking
stations are due to poor cable contact.
If you want to disconnect One Dock from the PC host OCulink connector, you
should turn off the PC completely first, and then unplug the OCulink cable from
the PC.
External Identification:
Indicator Lights:
There are two indicator lights on the front of One Dock V2, the upper one
is the OCulink connection status indicator and the lower one is the Thunderbolt
connection status indicator. Amber color means powered on but not connected;
white color means connection has been established with the PC host.
If the OCulink cable is correctly connected but the indicator light is
still amber, the host computer may not be powered on or the cable has poor
contact.
Adjustment Switches:
There are two adjustment switches inside of One Dock, located at both ends of
the PCIE slots, which can be adjusted by reaching into the slots and toggling
them with the wrench included in the spare parts kit in the event of a complete
power off.
FULL-HALF fan speed adjustment switch: FULL means the cooling fan inside is
running at full speed; HALF means running at half speed, which can reduce the
fan noise, but the heat dissipation will also be reduced. The factory default
is FULL, adjusting this switch is at the user's own risk.
AUTO-ON graphics card startup adjustment switch (only valid for OCulink):
AUTO means that One Dock follows the PC host to start up, the graphics card is
powered on when the PC starts up, and automatically powered off when the PC
shuts down; ON means that whatever the PC host starts or not, as long as the
OCulink connector is plugged into One Dock, the graphics card will be powered
on. One Dock can't get the startup signal in some adapter boards or PC hosts,
so this switch is set.
Interfaces:
The back connectors from left to right are:
5557 Power supply connector (CPU 8-pin): When using 20V GaN power supply as
a power supply output connector, connected to the graphics card external power
supply connector; when using 12V ATX power supply as a One Dock power supply
input connector.
DC7450 Power supply connector (for external 20V power supply)
Upstream Thunderbolt connector with PC icon for connecting to PC host and
provide up to 96W reverse power supply.
Downstream Thunderbolt connector, provide up to 15W reverse power supply,
for connecting other Thunderbolt/USB4 devices or docking stations.
Front connector: OCulink 4i
Troubleshooting:
Error 43 When Connecting with OCulink:
This failure mostly occurs in NVIDIA external graphics card, especially
through the M.2 interface external NVIDIA card, which is a common problem of
external NVIDIA card, not the problem of the graphics dock.
Please first download and install the latest graphics driver from the
official website, then download nvidia-error43-fixer_113.zip from here.
Unzip and run nvidia-error43-fixer.bat, and select "Yes/OK" to authorize in
the UAC window that pops up.
If you see the following message, it means the script has automatically
fixed error 43 and reset the graphics card.
At this point, the graphics card can be used normally. If you replace the
external graphics card, or remove the graphics card device from the device
manager and reinsert the card, you may still encounter the 43 error, please
follow the above steps again.
