I’m building a 48 node pi cluster and to make sure I get the highest reliability I’m testing a couple of pi brands with my application. This application is doing calculations 24/7 so all cores are at 100% all the time. I have two Rock Pi4a boards running together with original Pi3b+ and two versions of the Asus Tinkerboard - total 13 pi boards. Only board to fail is one of the Rock Pi 4a boards.
This setup is well cooled with heatsinks and fans. The core temp in the rock pi 4a is around 68-70 degrees celsius so that should not be any problem.
Anyone else had a board failing ?
I just ordered four more Rock Pi 4a boards to see if the failed board was just a unfortunate mishap. I really want to use this board because it’s the fastest board I found so far. But if reliability is a issue I will have to look elsewhere.
