According to both Asus and Mushkin, I should have no problems at all getting the memory to run at DDR 400... i tried following all the guides and what not, and they really aren't helping me too much, with this particular issue although they do help with future overclocking. Of course, I am not exactly trying to overclock. I did try and just set everything to auto and changed my memory to DDR 433 in the bios, and my pc failed to boot, so I had to reset the CMOS, so that did not work at all. Mushkin tells me that I had to be sure and set the timings and voltage for the memory to exact timings to get it to work at DDR400, and if I try DDR433, I would have to overclock (which you guys already pointed out to me).
Now, as far as asking you all before I bought it, how hell was I supposed to know anything about all this, to ask in the first place??? I notice that there are a lot of arrogant people on this board who seem to thing everyone should be able to OC like a champ, but I am not mentioning names. I am just tired of people questioning my purchasing decisions on here. You know why I bought the FX55 and 4 sticks of DDR433? Because I felt like it, that's why... This post was not intended as a "ask for buying advise" post, it was intended as "how to get to work" post.
All this being said, if anyone sincerely wishes to help me with what I have without removing anything, I very much appreciate it... For those that don't, go fry your own A64 3200's and leave me alone. At least I won't criticize your purchasing decisions!
