I had all sorts of problems in bringing up XP3500+ on Abit AV8 w/ 1GB Corsair twinX. My poor retailer, although well paid, swapped motherboards, memory, processors, the garbage can, and a few more things on five different trips to the store. Ultimately, I bought a new power supply, primarily out of desperation, as I was down to a breadboard setup w/ MB, 3500+, memory, video card (tried two different good working cards). Things got squared away w/ the new power supply.
Despite the fact that my Antec True550 power supply was less than a year old and has always worked reliably, I contacted Antec in the event that they new something that might cause a problem. Sure enough, there are some versions of the True550 (perhaps other models, also) that have incompatibilities between the Antec power supply and the Abit AV8 MOBO. In a brief email from Antec (I expect more information tomorrow from them, as they will RMA my True550), they did not go into the details of the incompatibility, but willing acknowledged it; they also said that Abit had to make some changes to alleviate the problem, also.
It seems to me, based on my own experience (This was absolutely the worst processor-motherboard-memory bringup I've ever gone through), that there are some real sensitivities between the Athlon 64MB's, the memory and the power supplies. And I have a feeling that a lot of problems that people are seeing with memory may be in this arena. Although my bringup scenarious were littered with inconsistencies, the majority of the POST stops were RAM-related; Corsair tech support even suggested that I had a bad couple of sticks and to try to swap it.
This whole thing really only came to light when, for the fifth day in a row, I went back to the retailer, he took everything I had used in my breadboard, plugged it in and everything ran fine, including an extended memory test; it was only then that I began to have SERIOUS doubts about the power supply.
FYI, all voltages measured within spec, the scope didn't show any AC creeping through, so I still don't know yet what the incompatibility is. But my hat is off to Antec for readily admitting the problem and offering to RMA the power supply.
I hope this helps others of you who seem to have hard-time bringup stories with new AMD64's, mobos, and memory.
BTW, no temperature problems so far using AMD's "PIB" sink and fan.
