Fixed my stability problem.


The cause of my troubles is the pencil mod. I gently wiped it off with a small paint brush and blew out my case.

Now it's stable running again at 4.05GHz and DDR 1199MHz with tRD 6 and tREF at 16120T with the same settings that I was using with BIOS 0902.



Prime95 custom blend amount of memory used 3200MB.






EVEREST Cache & Memory Benchmark.





Small gain than using a refresh period of 16383T with MemSet.


Also running fine in Ubuntu 64 bit so I can say that it's possible to use a refresh period of 16120T for 24/7.
