If you have a 965 you can try everything independently and use the Bclk for granularity between multipliers. If you can't get a 200 Bclk I would think that tuning that independently would be the first step. The QPI is 3.6GHz which is fairly close to the stock 3.2Ghz 965 setting. Can you make 15x200? It should be similar to any other system. I tried, so far unsuccessfully, to get posts of Core i7 settings in a different thread. Otherwise, they are spread all over.

Have you seen the NCIX video or read Saaya's thread?
