30min of prime95 blend test stable settings now.
Notice that VCCIO needs to be raised for stability. DDR voltage is not a problem 1.6375v can probably be lowered a little. Maybe down to 1.6v. With VCCIO @ default, test will give error with whatever the DDR voltage is. I tried up to 1.65v DDR. Still error. After raising VCCIO to 1.1125v i lowered DDR to 1.6375v. Didnt have patience to try even lower today. I will do that later on, some other day.
Also lowered tRAS to 27. This can also probably be even lower, but didnt try. tRP can not be lowered under 10. Will give BSOD. CL and tRCD can maybe lowered, but i doubt it. 9-10-10 seems reasonable and logical for this ram.
Touched ram chips several times during the test. They dont get very hot, but probably will be safer to put heatspreaders on in future, if using above 1.6v and stressing them a lot.
OK. Heres the screen. Hopefully it helps someone to OC their P67 RAM sticks.
