Hmmmm....
Okay. Let's through out a whole bunch of shit and see if anything sticks.
This board has several different revisions only two supporting the Semperon chip (v. 6 and v. 8) The one being sold at outpost is v. 8.
Is that right?
Well, I'm going to assume it is because that's all I could find there.
Two jumpers on the board have to be switched to get it to run at 333mhz. Two columns of three on the right with the top two of each column shorted out. I'm sure you've done this right, after all you said you switched it back to 266mhz and it ran fine. So, it doesn't sound like you might have misread the diagram.
You've downloaded the latest BIOS for this board, which according to this
page is version 8.0d, but this
page has it at 8.0e.
Which one have you downloaded?
You've checked the powersupply.
Of course, the memory has to support the 333mhz FSB as well, but that doesn't seem to be the problem. You've told us it's pc2700. The memory isn't corrupt otherwise you'd get the error all the time regardless of the setting. One stick at a time would be worth checking out. Try them both seperately maybe it is bad memory, though I seriously doubt it.
You're sure it's a Semperon 2400+. It's not a powersupply issue. It's not a memory issue. You've updated the BIOS and set the jumpers right.
I don't know. There's an off chance it might be a heat issue. If that were the case, however, I'd imagine it would shut itself down randomly. Not hang at the same place every time. Not to mention immediately setting the jumpers back wouldn't cool the chip down so there would still be a considerable wait to boot it back up.
I've read of instances where an AGP video card will conflict with BIOS settings and prevent the PC from booting up, but if that were the case it wouldn't matter what the FSB speed was. It wouldn't boot up at all.
I can't say what the problem is right now...
Let me do a bit more research and ask a couple of friends. I'll see if they have any idea what's going on.
