For memtest86 the reporting is a bit conservative. It’s almost the exact same bandwidth as 1DPC fwiw.
aida64 reporting 75ish gb /sec is not quite an apples to apples type comparison.
It is still not all sunshine and lollipops for any cpu on any board.
I could NOT get ddr5-6000 stable on zen4/7900x but generally 9000 series amd cpus have been okay. Not always @ 6000 sometimes 5600, sometimes less.
MSI and Asus lead the pack currently,
then asrock
with gigabyte bringing up the rear.
the GB X870E aorus master just got a bios and the Asrock boards just dropped bioses the last day or two, so still testing those. The aorus master was slightly unstable @ 6000 in 1+ hour memtest86 sessions. the asrock boards are still hit and miss BUT I JUST got another fresh set of bioses to test.
reeeeee
