I have not bad M730 (max with cold water 3160MHz w 1M Pi) and I have ocasion to change them for M780
I had M750 too, but not great clocker (max 2900Mhz)
What can I expect from M780 ??
Is the averange OC better than averange OC M730 ??
Thanks

On air they seem to get ~3ghz, so cold water maybe 3.2 or so

Your 730 seems just as fast as my 780...:-/ Max pi for me was a flat 3200 on cold water. 3 GHz 100% stable regular water, ~3150 cold water.
I don't think a 780 can be any worse than that though.

well
I need higher multi ...
So there's no rule in Pentium M :)
3 gig > 3.3 gig air
3.3 gig > 4 gig mach/vapo/dieice/ln2

On air is that with what voltages?

i was searching google, and came across a site, that had a cpuz and it said 1.7v but i couldnt translate the language, it could have been a sucide shot.

With a decent heatsink, NORMAL ambient temps (no cold weather outdoors runs), Pi stable is generally between 2.9 and 3.0. Of course there are several "air" runs with -30C ambients or so at 3.2GHz, but I'm not counting those.

Is 3.0Ghz duable with good air and P4C800 volts (1.6V Bios) with no mods...?

SuperPI, sure. 24/7 useable oc, only from a gem, don't count on it.

So its not worth going to a 780 if I already have a 760 at 2.8Ghz...... What do I need to have it at 3.0Ghz on air?

if you can get water or single phase, then get the 780
otherwise stick with ur current chip.
what multi fsb have u booted up to get 2.8 gig ?

I can either do 12 x 233 13 x 215 or 14 x 200..... currently at 12 x 233. If it gets colder then I can boot at 12 x 235 and actually use it in benches and stuff. So getting an 780 ES wouldnt matter....._
