" rel="nofollow - Anyone try this new 4.90 BIOS on those boards?...i have Ryzen 1600 and AB350 Fatality k4 board and every time i try to overclock CPU with BIOS 4.xx my memory bandwidth in aida64 and other benchmarks is lower,because memory timings got messed up with any CPU OC(well known bug)...is this BIOS finally address this ,or i should stick with BIOS 3.40 where everything works fine with Ryzen 1600.
