I didn't get an answer two months ago when I asked the same
, so good luck for you. I can't tell from my own experience if the SR-X beats the Z9PE-D8 WS BCLK-wise, but I haven't seen a Z9PE-D8 WS setup doing 105 MHz or more yet. 104 MHz seems to be the limit for most users, so I would like to know as well if higher values are possible with the Asus board.
btw I have to be a fool to believe in transparency being beneficial for the community and try to include additional information like the mainboard I used on the screenshots and fill out the result details but I will continue this way.
