Question Z390 Aorus Pro 3 Beeps

[skinnyrat]

I have just built a PC , Z390 Aorus Pro I7 9700k stock settings, everything seems to be fine it has not crashed, temps are fine, I can play games ok, the only problem is every now and again it will beep 3 times , but still runs ok, any ideas?

Perhaps try running memtest86 on each of your ram sticks, one stick at a time, up to 8 passes. Only error count you want is 0, any higher could be cause of the beeps. Remove/replace ram sticks with errors.
