First, I recommend only running 2 dimms for a few reasons, 1) voltage, 4 dimms take twice as much power as two dimms, 2) stability, apparently DDR2-800 support is touchy on this board with 4 dimms installed, you may have to select DDR2-667 to make all 4 work properly. Also the fact this board selects 1.8v automatically, this may be below the requirements for your RAM.
Personally i bought the cheapest 4GB kit i could find, the G.Skill F2-6400CL5D-4GBPQ, which is not listed in the compatibility list, but i've had absolutely no issues with it. This ram easily hit 1066MHz at 5-5-5-15 1.8v, and currently runs 800MHz at 4-4-4-10 1.8v. (Never had any boot issues with this kit)
My only "goal" with this Pentium D was to hit 266MHz FSB, which it did just fine at 1.175vCore (50mV below stock), for a total of 4258MHz. However, I'm still using the stock Intel HSF, so I'm currently running this processor at 3.2GHz, 1.100vCore, which remains nice and cool. I -may- be able to go lower, but I haven't bothered to try, nor have I bothered to try going above 266MHz FSB, although I may attempt higher FSB clocks once I invest in aftermarket cooling.
The best advice I can provide is to follow the accumulated information within this thread, most importantly, I think, is to enable LLC (Line-Load Conditioning), which all-but-eliminates vDrop between BIOS and Windows. I can say my current setup does not budge from 1.100v with LLC enabled, at idle or full load. I would also follow the advice CrazyNutz provides in this thread, but adjust accordingly since you have a Pentium and not a Core 2.
Good luck,
