We build a new system and get a C5 error with a long and two short beeps. Everything is connected and the RAM we using should be compatible. Its Gskill Trident Z5 Neo RGB. (F5-6000J3038F16GX2-TZ5NR) DDR5-6000 16GBx2. We put the two modules in A2 and B2 like the manual told us to do. We are clueless what to do now.
