Custom Resolution Utility (CRU)

Is there a formula for determining the required vertical blanking / maximum bandwidth to keep memory clocks down (amd)?

1920x1080@144 freesync, CVT-RB/CVT-RB2 sets vblanking at 77 lines.
2560x1440@60, CVT-RB sets vblanking at 41 lines. Setting this to 77 allows clocks to come down. This monitor does not like CVT-RB2.

I have a third monitor, 1920x1080@60, that I'm also trying to drive off the gpu. Tried setting it to CVT-RB2 with vblanking at 77 lines, but no luck. Currently have it hooked up via displaylink adapter.

Thanks
