An odd behavior with my Opty 165.

[Link]

It's a 0551UPMW. I had o/ced it to 2520mhz@1.36V(actual) dual prime stable.
Last night, I pumped it upto 2538mhz(282x9)@1.36V, and dual prime immediately failed on core 0, but core 1 was still running strong. Then I tried 2547mhz(283x9)@1.40V, and this is where the odd thing happened. Instead of the core 0, core 1 failed prime within 2 minutes! The temperature during dual prime runs was never over 53C.
Any thoughts?

53C is pretty serious heat boss. What kind of cooling do you have?

If you're at 53C with only 1.4v, you need better cooling in your case.
