socket replacement and bios chip problems

[Weltoris]

Have been playing with bios cross flashing and hot flashing.
Have got an asrock am2/am3 motherboard (n68S ucc) and successful flash to a similar am2/am3/am3+ motherboard (n68gs fx).
Board works as it did before with an athlon II 620, however does anyone know where I could get a replacement CPU socket (am3/am3+)? To then try an fx CPU.
Was thinking of buying some dead boards off eBay for this

Also have cross flashed a Packard bell 775 board to an ecs bios (also working well and more options etc in bios).
And An Acer t180 to abit bios. (having spare bios chips from old boards has come in handy).

One problem I have come across, is with a couple of winbond 25X80AVAIZ bios chips I have, they both fail the verification after being flashed. Would anyone know why this is? (I have tried them in three different boards, and each time they do the same)
