DDR Ref = +2%
Voltage = 2.20v
MCH = 1.48v

I've tried several FSB:RAM ratio combos but nothing seems to be working. Is true that lower FSB = more stability? I'm a noob at fine tuning my memory subsystem. Also, what would be the highest MCH voltage recommended? Should I apply my own thermal paste on certain motherboard heatsinks (northbridge, southbridge, etc), and if so, how?
Our problems seem to be very similar, except that you have faster Ballistix.

I did some google search on running 4 DIMM's on P35 chipsets and after a while of searching came across a post explaining DDR2 timings, where I learned that if the cycle time (tRAS) clocks exceeds the sum of the CL, tRCD, and tRP clocks, you're more likely to achieve stability.

So I loosened my timings from 5-5-5-15 to 5-5-5-18 and that seemed to have helped a lot, in conjunction with the +2% REF voltage setting in the ip35 pro.

Perhaps try loosening your timings to 4-4-4-15 and see if that does it?

Edit: And what is your FSB currently at?
