I gave up on trying to stabalize my memory synced at 1811, just couldn't do it...

so I backed it off to unlinked at 1610 and started to explore the boundary conditions of the data corruption. I found that it was dependent on NB, RAM and VTT/GTL voltages. According to sfc scan, I have integrity violations at NB = 1.46 and RAM = 1.9 even though I am prime stable. a bump to NB=1.52 and Ram=1.96 and there are no more data corruption issues per sfc scan!

so here are my settings that are 100% prime stable and have no file integrity issues!!!

FSB: 1811
RAM: Unlinked @ 1610, 7-7-7-24 (all subtimings on auto)
Multi & Vcore - set to your preference (I've tried @ 9 multi for 4.0 and 9.5 multi for 4.3 and they both work)

VTT=1.36
PLL=Auto
RAM=1.96
NB=1.52
SB=1.6
GTLs=-29,-32,-32-,29

on my machine these settings are 100% stable (prime & 3D) and result in NO CORRUPTION!!!
