All you may have gained you threw away with the slower ram - and you are trying to tell us that your rig was faster? You do know that with today's CPUs the CPU is not the bottleneck - the slow as molasses, no speed bump for 10 years ram is. (just look at the internal clock rate of dram chips - and you realize that ddr1-3 are pretty much the same crap).
