I've been trying to get an out of the box 1ghz thunderbird to work on an Abit kt7a-RAID for about 3 days now. Here's what I've tried so far:
I've only been trying to boot with an AGP voodoo3 (screwed in and not screwed in), 256megs of generic pc133 SDRAM, a 300W power supply, and the thunderbird/heatsink/fan. I've also tried booting with a HD, Floppy, CD-ROM, and NIC, but no luck.
The first thing that would happen was that I'd get a long, continuous beep on powerup, then the system would shut down. Figured out that I didn't have my CPU fan connected to FAN1. Then only Voodoo3 info would appear on the screen on powerup, i.e. no memory check, no "Award BIOS v. xxx" info. I would turn it off, remove all power, clear the CMOS and try again... sometmes immediately, or after waiting an hour or so. I repeated this enough times to see that whenever I'd leave the system alone to cool down, it would get further than when I didn't. So I thought, "ok, it's just getting too hot". I'm using an aluminum heatsink and a Cooler Master fan. Thing is, these are old parts from an old celeron system. Are they big enough? They seem to fit ok, but they don't *completely* cover the entire surface. Especially the fan. I'd say the fan is about a millimeter smaller than the heatsink on each side. It's also not a very big or powerful fan.. have no idea what kind of RPM it gets. Is the fan fast enough? Is the heatsink clip not doing its job? It seems to be fairly snug, but I may not be getting the contact I need. What about the 4 rubber cushions on each corner of the chip? Could the be too big, preventing the heatsink from making good contact? Aghh, I don't know, and I'm open to suggestions.
I'm pretty convinced it's a heating issue, because when I applied a new coat of thermal paste, and lightly pressed down on the fan on powerup, I actually got into the BIOS (yay!). I just navigated through the menus until my system eventually locked up.
Taking that all into consideration, it may also be a memory problem. The manufacturer I bought it from said it would work only with VIA Apollo chipsets, but I have that. Also, sometimes when the system hangs, it will be during the memory check. However, like I said before, it's erratic--sometimes I get to the BIOS, sometimes I don't.
Any suggestions?
