Here are the results of my highly unscientific tests using the Winrar bench:

620 - 2.5-3-3-7 @227, 166 div
589 - 2.5-4-3-7 @227, 166 div
586 - 2-2-2-5 (errors) @185, 133 div
586 - 2-2-2-7 @185, 133 div
552 - 2-3-2-5 @185, 133 div

I didn't get Winrar errors at 620, but Prime is now yelling at me.

Your cas 2.5 and 50mhz advantage puts you over top - cas 3 would lose dispite 50mhz advantage.

That's a little tougher but you can try it easy... the most demostrative test, and correlates best with games and other real world scenarios, is winrar's internal benchmark. (highest number wins) But even with a 41 Mhz deficiency, yes, I think you'll find the underclocked choice is faster.

I assume your 2-2-2-5 @185MHz is with 133 memsetting and your 2.5-4-3-7 @227 is 166?

That means you're 133 will actually be 178.71 Mhz or (DDR357) so it's almost 50Mhz difference.

I disagree on the note that winrar resembles other real-world applications, even games.

While it happens to correlate with machine parameters when comparing it to some gaming benchmarks, these gaming benchmarks are usually those where people erronously try to "get the GPU out of the equotation" by running an older game at low video quality - at FPS number well above 150, even up to 300.

While such a high-FPS game benchmark is still a game run, it has no resemblance to another a modern game which is fps-challenged on today's CPUs will do.

Because at these low CPU loads any game basically turns into a useless memory bandwidth benchmark from shuffling its textures and other large data around. More modern games are entirely different as they do more actual computation, and on the grphics side they now push shaders, they don't suffle much more data around that the older games.

What would be excessively useful would be take the Quake 2 engine and make a variant which actually omits everything to do with the graphics cards, so that you can benchmark the code that makes up game mechanics, physics and AI. Or lets say me still move the graphics data round by to a specific place resembling a sink.

What difference does that make? Run at any res/any shader model you choose. If there is any difference in the game/ 3d modeling app etc - if results are in the positive so will winrar be - if results are in the negative so will winrar be negative. Always no exceptions - unlike say sandra where you can show 1000 more pts in their mem test and still lose in lots of games at that setting.

I don't mean correlates as in a 1:1 linear relationship - I mean if if results are in the positive so will winrar be - if results are in the negative so will winrar be negative. - It just so happens winrar is most demostrative and accurate at predicting if it's a gain or loss if any at all.
