I recently upgraded my system (new psu, cpu, heatsink, gpu and memory modules) and after failed system starts (just the fans would turn on) and some puzzling, I isolated the RAM modules as the problem. Using my old sticks my system starts and works fine. So I sent them in to the shop and they told me there was nothing wrong with the modules. Now I'm wondering about their compatibility with my system.
What are the required voltages for each brand at 800mhz, the system is going to set it to 1.8 but thats probobly not what either chip needs.
Try setting ram clock manually to 400 or (x 4) and the voltage to 2.0 volts
