Nagging question about P4A

[Bernardsville]

I have a P4 2.4a running at 3.4 stable at stock voltage. I got a IS7-G for mad cheap off of Newegg for like 40 refurbished. Which allowed my kingston valueram 2700 to be dual channel. The FSB is 142 while i did the 4:5 ratio to get my ram running at 177. On the Sisoft, I get my memory bandwidth up to about 3600, while at 1:1 its about 3300 with tight setting and GAT settings on the highest. My question is, should i keep it at 1:1, would that make the bandwidth and memory work better, than having the memory at 177 with looser timings but higher actual bandwidth.

Cheers, Jonathan

run nbs400 3:4 ratio for best performance
bump vdimm to 2.8v and use the lowest cas settings you can
