Better trade-off Ram Timings or CPU?

Hi All,
Quick question,
I am OC'ing my 4000+ chip. I run stable @ 2700 and @2750 for hours without any issues. CPU temp is ~ 34 and system temp is ~ 38-40 under load.

@ 2700 I run 225X12 with my memory at 2 3 2 6 1T PC 3500LL
@ 2750 I run 250x11 but my memory can not handle 2 3 2 6 1T so I have to drop to 2.5 3 3 6 1T.

I see a pretty big improvement in AM3 with the 2750 settings. I am 95185 in AM3 and 9126 in 3DM05. The numbers seem pretty good but I was wondering from the experts which way they would go. Higher processor slower RAM timings OR slower Processor faster RAM timings???

What are your thoughts folks?
Thanks in advance,
-Paul

You're asking if 250x11 is faster than 225x12 given those RAM timings? Hmm...this is a tuffy....hm....comparing 2-3-2-6 to 2.5-3-3-6.....hm......Go with 2750 and put HT @ 5x, see if it runs @ 1250MHz, if it doesn't, run 4x and be happy with 250x11 and 2.5-3-3-6, or increase the voltage to your RAM and run 2-3-2-6 again.

Thanks Mike, I will try the 5x HT for 1250, increase the voltage to 3.0 and try 2 3 2 6 1T. Thanks for the help and suggestions. Ultimately I would like to try and get stable at 280x10 2 3 2 6 1T on this box but I don't know if she will handle it.

wusy,
I tried google but can't find bungholiomark, where can I get it?
Thanks again,

Seriously, why can't I get Beavis over hear to BM my system? Do I want BungholioMark 2005? Is there a DOHDOHDOHmark anywhere? It would be much more appropriate because that is what I say the whole time...I really prefer the Simpsons...

You can always run a Ram Divider and drop the memory in the 250x11 example. Run it at 6:5 or 8:7 if you have it, and will be running the Ram at 207 or 219, which should work at the higher timings.

1250 HT shouldn't do much for your system performance, since the 1000 HT isn't being fully utilized in most cases.

I'd go for the second option (250x11) even at CL2.5 .
Benchmark both. Anyway i'm sure they're very close in performance.
