ASRock Launches EPC621D4I-2M Mini-ITX Motherboard for Intel Xeon LGA-3647
The ASRock Rack EPC621D4I-2M Motherboard
ASRock is no stranger to shrinking powerful platforms down to sizes others companies might fear to reach, and their ASRock Rack EPC621D4I-2M motherboard is another example of this. This mini-ITX board is based on Intel’s C621 chipset and offers an LGA-3647 socket for Intel’s Skylake-SP and Cascade Lake-SP Xeons – up to a max 205W TDP, that is.
As impressive as it is to make an LGA-3647 socket fit into mini-ITX with four memory slots (SoDIMM, of course), there isn’t a lot of room left for things like a beefy VRM (and large VRM heatsinks). Can 6-phase power and small heatsinks cope with the realities of up to 205W TDP processor loads? And what cooler might work in a tiny server setup based on this board? HWP.ru (Russian language) has a review of the board which we found via WCCFtech, with details on their build and many more images – along with some benchmark results.
"When the Intel Xeon processors of the LGA-3647 series only appeared, many experts joked that this processor socket is so large that it is impossible to make a Mini-iTX board on it. And ASRock Rack showed the world that nothing is impossible for them, and if you need Xeon Scalable on a nettop board, please, the company has an EPC621D4I-2M motherboard for you."
