Comment (by rudolfc):

 Ah yes, you are applying the same non-packaged-system trick as I do.
 Thanks for clarifying.
 I am looking over the code, maybe don't touch the lanes, as that's
 actually working OK.

 Instead change the fixed base frequency to half that or double that (see
 which one will fix the refresh, I am guessing half the rate.

 It's in Ports.cpp, routine _SetPortLinkGen8(), item LinkBandWdith (now
 270000).
 This one I still need to autodetect as I tried to imply above.

 Let me know, OK? I'm very curious indeed ;-)
