Memory Speed or Clock Speed

[Falloutboy]

Ok I got a Opty 142 and have been running at 2.4 do to crappy DDR333 Ram. well finally got some DDR400. but do to the ram not wanting to go much past 200 and my board not having the voltage to push my chip too 2.7 at a 300fsb (stock voltage only and I know this chip would do well over 2.7 with some modest voltage since it boots at 2.7 already just not stable.

186 Memory Speed running at 2.62 using the 133 memory divider
or
205 Memory running at 2.25 using the 166 divider

what would you guys do?

You'd be willing to give up 350 Mhz of cpu speed, just to get your RAM on the next higher divider? You must not know much about Athlon 64's architecture. You'll be losing ~100 Mhz worth of cpu performance, by running with the lower RAM divider. In other words, you'll really only gain ~250 Mhz worth of performance, not 350 Mhz. Now, ask yourself, do I want to run my cpu @ 2.25 Ghz, or do I want to run it at 2.5 Ghz, and you'll know the answer to your question.

I think your over simplifieing it but yah thats what I figured. what it really comes down to though from what I understand is if my CPU is saturating the FSB (memory bandwidth) and i don't think a single core athlon does in normal situations.

Well, of course I was oversimplying it. You asked whether 2.62 Ghz would be better than 2.25 Ghz. BTW, why in the world are you asking us? You should be booting @ each of those frequencies and memory dividers, and then do some simple tests of your own, with whatever software you use the most. Do you care if there's only a benefit in the apps that I use, but none in the apps you use? See my point?
