Shadow I can't find any XP 3400 bartons, i think they stop at XP 3200. the XP 3400 is 64bit. Also the xptmc unclocker doesn't work on Nforce2 boards, a new locked CPU is locked on Nforce2 no matter.

If your getting a XP 3400 64bit you need a different MB, if your getting a new barton they're all locked now so if you want to use the xptmc unclocker you still need a different MB.

If you want a regular (non-64bit) barton then get one of the mobile chips, they're going like hot cakes and soon AMD will catch on and lock them also....
