HP T740 Internal Hardware Overview
Getting inside the system involves removing the rear faceplate, hitting the green tab (shown above) then popping off the lid. Inside, we can see a fairly interestingly laid out system:
On the top of the system we have a big heatsink and fan cooler assembly for the AMD Ryzen Embedded V1758B processor. This is a quad-core eight-thread processor with Vega graphics and is quite capable.
In terms of memory, we get dual 4GB DDR4 SODIMM modules, but these are upgradable for those that want more memory.
One can see the PCIe Gen3 x8 riser below. That is where an expansion low profile card can be installed.
Next to the memory modules, we get two M.2 slots. There is a M.2 SATA slot as well as a M.2 slot that can either take eMMC or NVMe SSDs. That provides a decent amount of storage flexibility, although it is under the PCIe slot.
Here, we have a small 16GB eMMC module. That is likely good if you want a lower-end firewall or thin client machine, but it is something we would upgrade. HP has a number of different options here.
As a fun item, the front USB connectivity is provided by a daughterboard and the USB ports are aligned along the chassis edge.
Sitting just above the empty WLAN slot on our system (there are wireless card options in these that we did not have) is another USB daughterboard for the rear USB, one can note that HP had to angle a single USB connector tower. Normally these systems we see aligned ports, but it is fun to see a system where they had to introduce this small design change.
Overall, this is a really nice system, albeit about twice the volume of a typical TinyMiniMicro node.
Next, let us get to performance and power consumption before getting to our final words.
