I have an MSI x570 board and 32gb Vengeance RGB Pro sl 3600mhz. When I start up I get a long beep followed by 3 quick beeps which is a memory fault Im told. All Memory is correctly and securely seated. All have the latest firmware v0.06.36. I have run memtest for about 8 hours or however long it took to complete and it passed with no errors. I have xmp 1 set in bios running at 3600mhz. When I restart I dont get and beeps, likewise if I turn it off and start again no beeps and turning it off and leaving for 10 minutes and back on and no beeps. It only gives the beeps when its been off for a while like overnight.Any Help
