Problem with e6600 and badaxe

[Tokenbrit]

Hi guys im hoping you have some ideas about this problem. Running an e6600 in the 304 badaxe and I am having some trouble OCing it, im not sure if I have some dodgy hardware or the bios is just confusing me. You can see in the picture my problem, failing dual prime at 3ghz. VCore in bios is set to 1.4, RAM is at 1:1 at default timings 5-5-5-12 and default voltage its the 6400HZ. The VCore reading in speedfan worries me a little but Im not sure if it is dodgy monitoring, PSU is a Tagan Easycon 530.
It primes fine at stock.

Well I tried VCore to 1.45 ram to 2.2 @5-5-5-15 and it seems to actually be worse, temps dont seem too bad. Im not sure how to disable speedstep in the badaxe bios, anyone know which setting that is?

As you can see I gave it plenty of volts and slack timings to make sure that it wasnt an issue, after googling a little I have disabled EIST in the BIOS, and used a program to disable C1E which I think was called halt/resume. However this hasnt helped. I will stick the memory back on auto when I get home from work and see if that helps, also check for a new BIOS however I thought I was on the newest one although I cant remember the number off the top of my head.
It doesnt seem to have any problems with a particular core, it fails on either but never both, single core load seems to be fine although I havent primed for long like that.
Anyone who has a BadAxe tell me some a good BIOS revision and some exact settings so I can rule that out?
