it's loud even with loud fans and an open case. i wonder if a bios update will help. i'd much rather find a fix then do the rma. listening to this sound for a long period of time, can give me a headache or permanently damage my ears. i have another question, i migrated my 5000+BE and 4 sticks of crucial ballistix pc6400 from my foxconn 590 sli board to this dfi board. with the foxconn, i can oc to 236x14 with memory speed at 944 and 1:1. i can run the timings at 4-4-4-12 on the foxconn, but on this dfi 790fx board, i can't at all even with high vdimm. of course everything is left at default on both boards. the only thing i changed on the foxconn is the 4-4-4-12 timings. i have to run at default dram config on the dfi at 236x14. sorry, it's my first time using this chipset and the dfi bios is pretty intimidating.
