HP has a new module out for its 1L PCs that many STH readers will be interested in. The HP Flex IO V2 10Gbase T Module (56Q71AA) is a small module designed to fit in HP’s 1L business desktop PC line. This is an upgrade over the HP EliteDesk Mini 2.5GbE Flex IO V2 NIC that we looked at in 2022.
HP Flex IO V2 10Gbase T Module 56Q71A for 1L PCs
We first showed this off in Perfect Project TinyMiniMicro Pushing a 1L PC as a Server Concept. If you want to see this in action, including the installation of the module, you can find it here:
The module itself is a proprietary HP form factor that you can see here.
Here is the back side of the module. This is not a full-size PCIe card by any means.
The Marvell AQction AQC113C uses a fairly decent heatsink. We do not have maximum power specs on this, but other units we have seen based on this chip are sub-3W.
Here is a view of the other side.
One small note is that if you do purchase these, sometimes the screws for module retention fall out in the ESD bag. It has happened to us twice already. Make sure the two screws are in the package.
Something we noticed is that the Flex IO V2 connector is larger for this module.
Here is the same Flex IO V2 system but with the 2.5GbE NIC. One can see that the 10GbE one is much larger.
Next, let us plug the module in and see it work.
Using the HP 10Gbase-T FlexIO V2 NIC
We tested the NIC and it showed up immediately in Windows 11 Pro. However, we will note that in our HP Elite Mini 800 G9 Review we found this caused us to need to go into locked BIOS which was our issue there.
We also tried with Proxmox VE 8 and it showed up immediately.
Overall, the Marvell AQction is a fairly well-supported chipset in modern OSes.
Overall installation time is around 1-2 minutes and requires only a screwdriver. The benefit is that this gives a second NIC to the HP EliteDesk G6 and newer systems with the Flex IO V2 slot.
We purchased ours for around $129 each, so they are about $100 more than the 2.5GbE NIC. They are also less expensive than getting a Thunderbolt 3 NIC for a USB 4 port (but that Thunderbolt 10GbE adapter is portable.)
Hopefully, this helps our readers in their Project TinyMiniMicro pursuits.
