You have mixed RAM so your faster RAM will run at the slower speeds of your new RAM. Second... You will need to go into your BIOS and adjust your new RAM to match your old RAM to get both of them at 800Mhz. g4kioN1 June 15, 2010 3:02:39 AM So i manually clock it to 800, is that overclocking my ram?

It may or may not be overclocking your RAM. You may have to down clock your original set to be stable... Just maybe. l4d June 15, 2010 5:56:47 AM tecmo34 said:You want the speed (DDR2 1066 Mhz), Timings (5-5-5-24-2N) and Voltage (1.65V) to match for all of your RAM in your BIOS [Numbers are examples not true settings].

Try a minimum of 1.8-1.9 volts when using DDR2 unless your RAM states lower like a Green series low voltage. g4kioN1 June 25, 2010 4:21:38 AM Best answer selected by g4kion1. Can't find your answer ?
