Do we pay much of a performance penalty by setting qpi to slow (gigabyte boards).
It looks like this is the setting I must use for qpi - if I want to use high bclocks with HT tuned on.
I think qpi on slow is something like - 100xbclock, so for 200 bclock that would give a qpi speed of 2000 vs stock speed (for 965) of 3239 mhz.
