Here's what mine did max on air, 17C ambient, Zalman 9700 (bad)

what batch is that ^^^^^

L739A554 (11/21/07 pack date) 1.2375VID 1.20V stock.

Benched upto 4.2GHz, 4.25G 1M should be fine (don't care about it).
Around 10MHz more was attainable but never saved it before I went higher and haven't tried again. 1.65V real will get 4.3G bootup easily but I can't risk the chip and by that time my PSU OVP kicks in and shuts down the system.

Max FSB with 1.472V was 496: http://valid.x86-secret.com/show_oc.php?id=301088

Actually it'll be 498FSB but I was lazy as usual.

Power draw/heat is too much for me to try more than 1.36V, ever. And everything passes +3hrs P95 (that I tested) at 1.30V for 3.6G but core3. It fails even at 1.328V, only 1.344V load will stabilize it fully and which means 1.360V idle.

1.28V benches 3.6G easily and 1.392V benches 3.84G and 4GHz easily that I tried. Stability definitely requires more than my cooling capability.

Just for everyones reference; it's good to know some solid tested facts

With this chip I need (all I've properly tested thus far - my full stability stated means sub 65C >8hr P95 load temps, videoing, gaming with just the 1 HS fan and >22C heatsink ambient):

MHz - BIOS/IDLE/LOAD (V)

3405 - 1.300V/1.280V/1.264V (fully stable)
3438 - 1.322V/1.312V/1.28V (fully stable)
3600 - 1.350V/1.328V/1.312V (fully benchable)
3600 - 1.362V/1.344V/1.312V (3 stable but core3 fails >3hrs)
3600 - 1.36875V/1.360V/1.328V (as above)
3600 - 1.372V/1.360V/1.3287V (fully stable)

3840 - 1.450V/1.392V/1.372V (fully benchable)
4050 - 1.468V/1.392V/1.378V (fully benchable)
4225 - 1.580V/1.472V/1.4365V (short benchable - not verified 3D)
4270 - 1.650V/1.600V/1.558V (short benchable - not tested much)
