So for about 2 years of using single 4gb ram stick I have finally decided to upgrade my rig to 8gb, bought 2x 4gb sticks of http://www.kingston.com/en/hyperx/memory/fury and switched with my old 4gb goodram. Now the problem as it seems to me is that no data is processed from the very start up. I do not get any classic BIOS beeps and screen remains black. For the record, I'm using this mainboard http://www.asus.com/Motherboards/P8H61M_LX/, as far as I understand both specifications, this setup should run easily on 1333mhz fixed frequency. Things to note: HDD diode does not blink at all, switching back to old 4gb goodram stick didn't help either.
