AMD B665 Chipset Powered Mainstream Workstation AM5 Motherboards From ASUS & ASRock Pictured

wccftech.com:

AMD motherboard partners seem to be offering custom-made B665 mainstream workstation AM5 motherboards to select cloud servers. One such cloud server operation is Hetzner which is based in Germany and two such motherboards that they are running have been discovered by Der8auer.

We know that Intel has a mainstream workstation lineup based on the W680 which supports both Intel 12th Gen Xeon CPUs. There's also the newest W790 platform which now serves the same CPU segment. AMD has had its socketed and embedded workstation families for entry-level users and the most recent platform uses the B650/B650E chipset with Gigabyte and others offering a range of options.

It looks like some motherboard vendors have also taken custom orders from leading smaller cloud & data center providers and manufactured completely new boards which utilize the B665 chipset. It is highly likely that this is a rebranding of the B650 chipset though there might be some underlying changes.

The two motherboards include the ASUS Pro WS 665-ACE and the ASRock Rack B6654DU-1L. These boards aren't meant for the DIY segment and orders or at least 1000 units have to be made before these can be produced before a specific customer. What these boards have in common is that they come with an inverted socket which is rotated by a 90-degree angle. The DDR5 DIMM slots are top-sided and the VRM position is downwards instead of sideways. The motherboards come with a tiny VRM/PCH heatsink & have the most necessary I/O that is required for entry-level workstation uses.

Now interestingly, the reason for the inverted socket doesn't seem to be for signal
