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.

Yup, AMDs don't like 4 sticks... and I'd say the faster CPU is better than faster Ram.

Is he running 4 dimms though? I was under the impression that he was running 2x 1GB dimms (didn't check to see if that mem comes in a 2GB kit or not).

MilitantPotato, if you are indeed running four dimms, than Namrac is spot on - trying to OC your mem with four dimms will only end in tears.

Yea, I'm running 4x512. The ram I use can handle 2.9 volts, but I'm not to keen on the VDIMM volt mod. Would it be worth it to spring for 2x1gb and shoot for a higher mem clock?

In short, not really. That board never did like running 1T for some odd reason (and it's impossible on any A64 or Opteron with 4 dimms), and like Namrac said (and I wholly agree - I've tried it), memory OCing with 4 dimms is a disaster. And, like I said before, you don't stand to gain much from it anyway. If you're system is running nice there, and she's stable, I'd say leave it, and enjoy.

I'm very happy with how it runs, I'd really of liked to hit 2.7 stable, but Prime95 couldn't complete one set of tests. Thanks for the help

No prob man - glad you like it, it should serve you well.

2.5GHz is faster than a X2 4800+ (a $650 CPU) and almost as fast as the FX60 (a $1000 CPU). I'd say that's damn good performance for $300.

Well, I was reading through some posts and found a step I missed, I turned off Cool and Quiet and am now at 2.7 stable. There is a problem with this board and 275 and up so any more might not be possable, we'll see.

What bios version are you running? ASRock bios version 1.30 and up have a 274 HTT loc, ocwbeta3 and higher has this same lock. You should flash your bios with ASRock official 1.20 or ocwbeta2 to get passed that 274 HTT lock. Check out this thread I posted about this very subject.
