i have 2x 1gb sticks of corsair xms2 800mhz ddr2 ram and 2x 512mb of corsair xms2 800mhz ddr2 ram. when i put them all together in my 750i mobo the computer locks up whenever i start to stress the system like playing crysis or something. on the 512 sticks it says 4-4-4-12. on the 1gb sticks it says 5-5-5-12. im trying to figure out how to make them work together but i cant figure it out. i set the timings in bios to 5-5-5-12 but i still had the same problem so maybe its a voltage glitch. any ideas?
