I am confused a little bit about the chip multipliers. Some chips (Xp1700, 2100 tbreds I heard) are locked at lower (0-12.5) while the newer bartons are locked at higher ones (13-??). But if the bartons generally have a lower clockspeed, a higher FSB (166) should they not have lower multiplier? Ex the 2500 barton runs at 1.83 and 166 so it must have a mulitplier of 11. Anyways some part of my info must be wrong, any idea which?
Also I read that the Epox 8RDA+ unlocks all mulitpliers in any AMD processor. Does the Asus A7n8x dlx do that?

well no, the fact that the bartons work at 166Mhz FSB is the reason why the multiplyer is lower, since CPU speed in Mhz is calculated by taking the FSB and multiplying it by the multiplyer... for example, an Athlon 1600 (@1.4GHz) has a mutiplyer of 10.5 and an FSB of 133 = 1396.5 ~ 1400, and a barton running at 1.83 has a multiplyer of 11.0... the newer bartons are 166FSB, while the older AMD CPUs aren't bartons, they're T-breds with 133Mhz FSBs

FYI, with the NF2 mobo's the multiplier's UNLOCKED paired with a Tbred B.
