I currently have 1GB (2X512) of DDR2 800 corsair TWIN2X1024A-6400 running at 4-4-4-12 timings at 1.95V (stock 1.9V). I am considering adding 2GB more to my system, however most 4-4-4-12 parts run at 2.1V. Is it safe to use this voltage on the sticks I have? What are the safe voltages for these parts? thanks.
