Is it better to run the proc slower in order to run the RAM at 220ish? or am I better off with lower latency/200-210mhz ram than a higher clock on the ram and really lax on the timings?
No MilitantPotato, it isn't better to run the proc slower to run the ram faster. Clock speed on your X2 will make a far more devastating difference in your real world apps (and just casual use as well) than raising your ram frequency will, especially such a trivial amount. Opterons and Athlons are not memory starved at all with that on-die controller. Synthetic benches (like Sandra) may make it look like you're gaining a lot of memory bandwidth (and you are), but fact of the matter is - your proc really doesn't need any more than it has already, and it will, at most, net you a 2% boost (and that's from a big jump in memory frequency - you wouldn't even feel that tiny 12Mhz difference you're mentioning). Whereas, running your X2 at 2.5GHz vs 2.2GHz will make a significant
difference. I'd say, if you're running your ram at 208 at those settings, and your Manchester is at 2.5, I'd be pretty happy with that. Also, who is saying that ram will do those timings and freqs? At what voltage are they running? 2.7V is all you'll get for vdimm on the high setting on that board - and I'd guess they're probably running a higher voltage than that to achieve those settings on those dimms.
