yeah, I knew much about this beforehand as I've been running boards with dual channel for a while. The problem, i've researched, comes down to two things:
1-running 4 dimms of 512 will niether allow 1T command rate nor will it allow 400ddr
2-running 2 1gig dimms dual channel will not allow 1T or 400ddr at anywhere near stable on my board with the older and cheaper ram
*the newer ram I linked above appears to have no problems running fast--check out the article and see that they address the issue Im talking about.
I appreciate the replies though, great helpful site
Edit: here some info from what I linked for your reading pleasure

Since that review in October, a number of 2GB DDR kits have appeared in the market with most based on Infineon C or B die memory chips. There are, however, a few brands that have taken a different approach to memory chips for 1GB DIMMs, and we have included those in this roundup, along with the latest Infineon-based memories.
1GB DDR DIMMs began appearing in the market over a year ago, but it wasn't until mid-2005 that 1GB DIMMs with reasonably fast timings became widely available. These faster 1GB DIMMs finally made the choice of 2GB memory kits to be a reasonable choice in a market that had been dominated by fast DDR 512MB DIMMs.
There are many reasons to choose a 2GB kit over a 1GB kit or 4 512MB DIMMs. Two 1GB DIMMs on the AMD Athlon 64 can still run at 1T Command rate, instead of the 2T required by the 4x512MB DIMMs needed for 2GB with 512MB DIMMs - a definite advantage for the 1GB DIMMs. On the other hand, until recently, the available 1GB DIMMs were generally much slower than the fast 2-2-2 DIMMs that were commonly available in 512MB DIMMs. We normally saw 3-3-3 or 3-4-4 or slower timings for 1GB DIMMs. These poorer timings for 1GB DIMMs took away most of the advantage for the 1GB 1T Command Rate.
There was an additional "gotcha" with the 1GB DIMMs that many enthusiasts quickly discovered. With a starting point of 3-3-3 or 3-4-4 at DDR400, the 1GB parts did not overclock nearly as far as the 512MB parts. For all of these reasons, we generally recommended that most users were better off with 512MB DIMMs - at least until memory timings improved on the 1GB DIMMs.
