Benching with 23 multi, I can do 5 ghz for 2-3 seconds using 14C ambients (vent of a/c to rad intake) but not stable enough to capture cpuz validate yet, I can validate 4.95, but already did that with my i940 (sig). When winter comes I will get 5+ghz easy with subzero winter ambients outside, which is what I needed to get 4.9+ on my i940.

With 24 multi I max out at ~4.85 with same vcore, vtt, ambient, or about 150 mhz lower. People using LN2 have complained of same thing, get 150-300+mhz higher using 23 multi than 24 multi for max MHZ.

For 24/7, same issue, I can bench 3D all day with 4.62 Ghz with 1.46vcore, 1.46vtt using 23 multi (http://service.futuremark.com/compare?3dm06=11376865), or 4.7 if use higher vcore but only 50% 3d runs make it, depending on temps. Using 24 multi I cant get 4600 stable unless I increase vcore about 5 notches, even then still crashes sometimes in a 3d run.

People are benching with 23 multi, because 24 multi sucks. Once you get down to around 4.4mhz on mine, the vcore requirement is not as different, just 2-3 notches more for 24 multi than 23 for same mhz.
