OC'ing a 165 vs a 170

[boozer]

Hello!

I'm trying to decide between an Opteron 165 or a 170. I understand the only difference is the multiplier. From what I've seen benchmark-wise, it appears that the 165's get very near the same speeds as a 170...
I'm kinda confused regarding the memory though. I understand that you can set memory frequency seperate from HTT frequency right? So if you have a 165 or a 170 that both OC to 2.6 Gig both running memory around DDR400 timings, there should be little to no difference between performance right? If I get a 165 up to 2.2 Ghz with mem running around DDR400 that should be roughly equivalent to an X2 4400 with mem running the same speed right?

The way I understand it, if I OC a 165 which has a 9x multiplier to a 244 HTT to get 2.2 GHz and run the memory at the same speed of 244, then this OC'ed 165 should actually outperform an X2 4400?

I feel like I'm missing something. Can someone tell me if I am?

Thanks!

Yes.

Exactly.

Exactamente.

Yes, It would but to OC the memory to 244 requires some more expensive memory and I don't think the small gain in performance is worth the money. I would buy some cheaper CL2.5 memory like Corsair Value CL2.5 and OC the CPU async to the memory bus.

They still getting decent OC's on the later 165's?

I think so, I haven't heard anything.
