The issue here isn't just one of those darned FSB holes, as problems happen with all combinations of FSB/ramspeed I have tested so far, except the 1333/1333 linked sync stock setting. Bios defaults is even unstable lol. I wanted to run FSB 1700 (= 4Ghz on the E8500) and 1600 mem like it's rated, but like I said no go. Stock FSB and 1600 mem isn't possible either
My board overvolts RAM and Vcore (and probably others). If I set RAM @ 1.86 in BIOS, I get 1.91 real. If I set 1.9 (trying to go to 1700FSB from 1600) I get hardware failures in Prime blend almost immediately. Drop it back to 1.86....so far so good for an hour or two. So, maybe try less voltage

I don't think OCZ and S2E play well together anyway....I've been through 4 kits and still fighting....1600EB 2 x 2, blue or white slots.

Which RAM did you use for QX9650 400 x 10 on S2E?

Good luck.
