You need to crank up your northbridge to at least 1.5v and your vtt to 1.4v I think your northbridge voltage is what is really holding you back. Mine is set at 1.55v in my bios.

ok here are a few results of my L804A515, pcb starting with 2L7, very disappointing at the moment I must say :

Idle 3.3G 1.4V vcore :



so it is 1.325V as others L80X


a few results :

3.2G 1.40V stable
3.3G 1.40V not stable
3.3G 1.425V stable (with 1.3V vFSB)
3.4G 1.425V not stable (5 seconds OCCT)
3.4G 1.450V not stable (BSOD after 5 seconds)

I'm running with 1.35V on NB for all of these, raising it up doesn't help. RAM is OK. Temps on full and idle are all right, and load temps don't increase much with vcore as some people reported on high VID CPUs.
It's like I'm reaching the max at 3.4, I'm going to try with more vcore or other settings but it's definitely not a good chip.


Do you guys have any recommandations?


EDIT : 3.4G 1.4875V not stable, and 3,456G 1.5V BSOD during boot
seems like it cannot even reach 3.4G... such a crap

I'm going to try 1.4V vFSB and NB but without any good expectation.
And I'm not going beyond 1.4V vNB as I burnt my previous Commando's NB with 1.45V after 1 week. (real voltage is the same as BIOS but Commando is well known for doing BBQ with NB).
