Yeah first of all, nice FSB OC on the DS3L. You should be running your RAM @ higher voltage(than 2.05v).. i run mine @ 2.2v(which it's rated for)...that might help some with stability. In order for me to hit 400FSB on my DS3L(E6600-403x9-XP-120),
i had to set vMCH +.3, vFSB +.2, and vPCIe +.2, PCIe@101MHz... as well as vDIMM +.4(Corsair 6400C4...my Ballistix 8500 wouldn't even let me hit over 390@ 2.2v also). I don't know if you've played with those settings, but it might be worth a try if you haven't. GL
