Thank you. It's done with an adapter. A very stubborn thing to use.

Well, it is not so strange, since you saw my 5.2GH by LN2 and your 5.1GHz by cool water years ago ?

IIRC, it's 5.4 and 5.2 accordingly

I thought they should scale much more under LN2. Maybe I need to try another sample, maybe just find the right settings.

Many CPUs have an FSB wall. Much like Conroes do (where lowering multi allows to expose it). That's why you see little scaling.

Any info on this? Which CPUs besides Core2, how to check this and so on?

Netburst have it. It's easy to see if you have an unlocked one. It's also relatively easy to observe when your max suicide clocks are only 20-30 MHz higher than your 32M clocks irrespective of voltage.

Does FSB wall scales on cold like on Core2? And have you seen negative scaling after some point?

They scale anywhere between 0 and 30 MHz. Haven't seen negative scaling.
