now, i had two ddr pc3200 400mhz 512 mb ram sticks in my computer, one was a ultra, the other, kingston, the computer came up saying all this crap about memory conflifct or somthin in a blue screen of death, i dont even see why there would be one if the sticks are the same type, ive never had this problem before, even with two totally differant brands... im really confused about why this is happening, i would have remembered more of the error had i not been so annoyed at my proccessor fan which i intend to replace whenever i can find a ride, this one sounds like The Wasp 5000 as my friend called... please help with this ram problem, 512 ram + celeron D = reeeeeeeeeeeeeeeeeealy slow
