Need F2-8500CL5D-4GBPK to run ddr2-6400

[larhome]

I just installed this 2X2GB Gskill ram with no glitches at boot. It runs straight out of the box at it's rated spec of CL5-5-5-15-1066 2.0-2.1V. I ran memtest for three hours with no errors. However they get very warm.
I would Like to boot them at CL5-5-5-15-800 1.8-1.9 V if at all possible.
I don,t want to guess wrong and fry my GA-EP45-UD3R !
What Bios changes are required to run CL5-5-5-15 at 800 MHz and 1.8 Volts ?

They would be fine, they are designed to run at 2.0-2.1. Ram is warm/hot by design, When it burns you that is too hot 2.2V+

Are you running stock 333 FSB? If so then here would be how you run those at 800. You may need to use 1.9-2.0V as they may not run at 800Mhz without doing so, at least not at good timings >>>
