I do not (yet) own a 78xxq. The photographs and most of the information presented here have been provided by Stephen or taken from 10ZiG literature.

The 10ZiG 78xxq was launched in September 2015.

Featuring a lightning fast AMD Steppe Eagle 424 Quad Core 2.4 GHz processor, configurable to 8GB DDR3-1866MHz RAM, optional Quad Video Output and an integrated Smart Card reader, 10ZiG's new 7800q Series Thin Client computer is poised to redefine the market.

The new 10ZiG 7800q Series is designed to meet the increasing demand within the VDI market to support power users who rely heavily on CAD, 3D graphic design and imaging programs within sectors such as Healthcare, Government and Manufacturing. Such power users also require ultra-high resolution (UHD) support in addition to speed and performance, all of which the 10ZiG 7800q delivers.

Power Supply

The unit requires a 12V supply and uses a 5.5mm/2.1mm coax connector (to be confirmed). The standard PSU is rated at 12V 4A. The basic power draw of the unit is quite low (<1A). Your power requirements will be dependent on what other boards/peripherals you add.

CPU

The processor is an AMD GX-424CC, a quad core 2nd generation AMD G-Series SOC.

Expansion

As usual, clicking on the photo (right) will take you to larger scale photos of the circuit board.

Flash: The unit came with a 16GB SATA DOM manufactured by BIWIN.

The board carries two options for installing flash memory. There is a conventional 7+15 SATA connector or an mSATA connector. This is an either/or situation as a SATA DOM or mSATA board need to occupy the same physical space above the motherboard. (see the board detail for a clearer photo).

RAM: The RAM is a conventional synchronous unbuffered DDR3 SODIMM plugged into a socket fitted on the top of the board. The fitted supplied SODIMM was a 4GB Aplus Technology part A+NDD31866BL-4G 21702.

Stephen also tested out a 1GB part (PC3-8500) and an 8GB Hynix PC3L-12800S part (HMT41GS6BFR8A-PB NO AA) both of which worked.

Google couldn't find the part number on the Aplus memory, but a utility shows that it is DDR3-1866 memory (clock speed 933MHz). The other two parts ran at 533MHz and 800MHz respectively.

mPCIe: There is an internal mPCIe socket where you could fit a wireless card.

PCIe: There is a physical 16x connector on a riser card to take a PCIe card.

However the connection to the motherboard is via a x4 connector, so whatever you plug in will only run at a maximum of x4 transfer speeds.

In using this expansion slot Stephen had difficulty plugging cards directly into it. The solution he found was to undo a couple of screws that attach the riser's metal bracket to the chassis. Then remove the bracket and riser, plug the expansion card into the riser and then replace riser/bracket/expansion card as a unit. Finally replace the two mounting screws on the bracket.
