I picked up one of the X13SAE-F boards to build a CFD solver for work. Only hiccup so far is the 1Gbit LAN disappeared (from BIOS and device manager), but a cold reboot fixed it. Running a 12900k and watercooling since these will see sustained high CPU usage. Board is revsion 1.02. Just using regular Crucial DDR5 (2x32GB), no extra ECC.
I've confirmed the out of box BIOS settings allow 24/7 241W CPU usage. I don't think I got a very good chip, it rarely hits any cores at 52x multiplier, but it'll do 49x all P core happily.
Our niche CFD software is only Win 10 approved and it scales poorly past 8 cores, so this seemed a good choice. I have E cores disabled while I run benchmarks on the CFD software.
Anyway, it'll be in testing for the next few days. If you have any questions or things for me to try, please reply.
