Soon (in a day or two) I'll have a version of OC BIOS that
will allow testing XMP profile w/o OC (CL7/DDR3-1333
in your case).
If XMP w/o OC gives issues you most likely have bad
DIMMs (or something off between CPUand DIMMs).
Also, re-testing @ 225 (I'm assuming that's what gave
you errors) and checking whether you get errors at same
offsets as before would be a worthy exercise.
Consistent errors would mean DIMM issue. Inconsistent
errors suggest OC/tuning/board issue.
Alternatively, if you have enthusiast board that supports
XMP you could test your DIMMs in it.
Eagerly awaiting the updated BIOS.. I've been rereading some threads and apparently missed the statement, you need better than 1333 Cas 7 memory to run over 225.
