Proves once more that they are unstable with my system, anyhow got a list of settings I tried before and these are marked as a failure. But I pass if I disable 2 cores

One important thing I forgot to mention, OCZ forums say that its because of quad core systems; they tend to strain the system more.

Do you get undetectable ram on CAS 9 when you link and sync your ram, or is it just 1104?
First it took 1202 for me to get QX9650 stable and I might add proper GTLREF voltage adjustments.
If core 1 and 3 ("cores 2 and 4") are failing at 49 min it could be heat related though.
IF not heat you may need to dial in a better GTLREF voltage not sure where you are at in this regard but the rule is if Core 0 or 1 fail increase GTLREF lanes 0 and 2 or if cores 2 or 3 fail raise GTLREF lanes 1 and 3 seeing your issue I'd say all your GTLREF voltages are set wrong. You need to find the high and the low that it will boot to then average them rounding up for a starting point for testing without changing your NB voltage if you change your NB voltages so changes your GTLREF voltage adjustment. So you'll need to test with a static NB voltage and resist bumping it + or - until you find the right GTL setting.
