It's MCH Read ODT at 8T that is limiting your overclock. Higher temperature needs a longer time to keep it stable.


Today my room temperature is 5° Celsius higher and I notice that I've got trouble to keep it stable running. Using MCH Read ODT 9T fixes the stability problem.

I also tried with changing DRAM Read and Write ODT but that's a bit difficult because I can't test it with MemTest86+. To do that I really need those timings in the BIOS.


I think that an MCH Read ODT setting in the BIOS from 8T to 16T should be more than enough to fix all our stability problems. I thing that running the board with 8 GB memory can benefit a lot from a longer DRAM ODT Timing.
