ok, ive change for the ocz 8500 memories, works for 10 minutes then i start to run orthos for stress memories and start to fail. and i didnt any overclock in those modules.after the system freezes and did not switch on again. apppear C1 on my mobo monitor wich means is memory. I take out and tested one module by one. One work and another one not even start the system. Hope is some factory problem since i did not overclocked the modules
i dont know now if i change the modules for same ones or back to the 6400 ones.
tks
