Hi there. I own a Strix X370-F and have an option called "BCLK Divider" in BIOS under my BCLK frequency setting. It defaults on AUTO and values selectable are 1 to 5. It is not LLC, there's a separate option for that. What do I divide with that? Clock for PCIe and stuff? My other question is about standard values of b-die memory at bios safe settings. If you own a X370 board, ryzen 1st gen and b-die mem I would love to hear your RTT and CADBUS settings for 2133mhz all on auto and 3200mhz xmp (or what your kit is set to). 2 screens of Ryzen Timing Checker would be nice. I try to dig into the RTT and CADBUS tuning more and want to know if there is a scheme involved which could be turned into a general rule for all maybe. My defaults at 2133, 3200 and even 3400 MHz are all RTT 0/0/5 CADBUS 24-24-24-24 This works for me stable up to 3400mhz. Any help is appreciated. EDIT: 7/0/5 + 20-20-20-20 seems to work fine for 3200mhz, too.
