If you are using dual rank or 2 DPC single rank modules, you don't touch these options at all. This results in BankGroupSwap = Enabled and BankGroupSwapAlternative = Disabled (the configuration I was using).
With 1 DPC single rank configuration you should either
disable both of them, or set BankGroupSwapAlternative = Enabled.
Enabling BankGroupSwapAlternative has the same positive effect on the real world performance as disabling
BankGroupSwap does, however it doesn't have it's down sides (i.e. the lower reported bandwidth figures).
