I have the foxconn 755a01 board with an a64 3000+, so I can comment on this. I'm not exactly sure I would call it a POS, but the memory issue is true. I have 2x512MB ram, but at ddr400 it gives errors in memtest. Tried both 2x kingston valueram and OCZ EL dual channel kit. Right now I'm running ddr333 (2-2-2-5) and its completely stable though.
I'll probably be returning it and getting something else (maybe that chaintech vnf3-250, though I haven't seen yet if anyone has gotten memtest passing with ddr400 with 2x512 on that either... anyone?)
Oh, and just a note. It does seem to have working agp/pci lock. BIOS has an "Async SRC/ZCLK/AGP/PCI" option. Default value disabled. Testing with the provided windows overclocking tool, with it disabled, I could get up to 210 fsb and going to 215 resulted in instant hard-lock. With the bios option set to "100/133/66/33" I could get to 220 and going up to to 225 would cause prime95 to error, but the system still didn't lock up. But I didn't do much more testing than that since it would seem a waste of time if I'm going to replace it anyway. And it lacks any voltage tweaking..
