Damn that's one hell of a BH-6 I've got a pair of XMS3200C2v1,1 with BH-6 and the highest I've done is 272fsb on a nf2 platform. 267 was sisoft stable(with sucky timings due to not enough volt). I didn't have a vtt mod back then and I've got no idea what the memory voltage was
Now I havn't got a unlocked cpu so I can't try no more

Clicky

Great overclock! Do some serious burnin now!
