Just curious, if I run 3DMark06 at 1600fsb, with 9x multiplier, my CPU is at 3.6GHz, and memory is in the 900s, my score is 16.7k.

If I drop my multi to 8.5, raise my fsb to 1700, memory jumps to around 1000 fsb, my score drops to 14.5k. Memory timing was adjusted to be tight at both fsbs. How the heck could my score drop so much?

indeed that is a great drop and a weird one, check when at the higher fsb if your PCI express is running at 16x speeds

Well the PCI lanes should be left alone no matter what you do. Just in comparison, going from 3.3 to 3.6 ghz brought me from 16k to 19k. So it might be perfectly fine. 8.5 had you at 3.4 correct?

Setting 1: FSB 1600, Multi 9x, Memory 960
Setting 2: FSB 1700, Multi 8.5x, Memory 1020

At setting 1 my CPU clock speed was 3.6GHz, at setting 2 it was 3.61Ghz.

No real speed difference to note, memory was actually running faster. Scores dropped...?
