FSB-DRAM Ratio Changed - Why?

[Davide Nativo]

Hi guys,

quick question: I recently updated my mobo bios 'cause a security update, and since then my FSB-DRAM ratio has changed from 1:27 to 3:54. Everything else is the same, as I set it personally, frequency (DDR4-3600mhz), timings (18-22-22-42; 631-2T), voltage (1.35v). Just the ratio has changed, and I can't understand why. It doesn't seem to have affected my performance, and after a quick google search it doesn't seem like it should. I just can't understand why it changed. Any ideas?

FSB-DRAM ratio has changed from 1:27 to 3:54

I have no clue why this would happen. Even more puzzling for me though is that the system is choosing to display "3:54" when that's an identical ratio to 1:18. Is there some significance to displaying it as 3:54 I wonder?
