Amd 2500+ or 2800+?

[mrgoblin]

Im worried now that the cpus are locked and such that I might not hit the right stepping and get screwed. Therefore I want to know will the 2800+ be able to hit 2.2 ghz with fsb overclocking or is there a place I can get a guaranteed stepping on the 2500+. Anyone know of a good stepping? Thanks alot in advance.

bump!

it's very rare the 2500+ won't hit 2.2ghz limited by the cpu itself.

most often it's the board or memory holding the 2500+ back from 11 x 200

nono I think you have it confused. Amd is now locking multipliers on their athlon line of cpus. This is in response to a flury of overclocked chips being sold at a higher price. After week 42 i believe, all chips are unlocked. Therefore unless you get lucky and find an old one, ure sol. I want to know will a 2800+ overclocked thru fsb high enough to hit 2.2 ghz. Hope that clears things up.

2500 uses same multiplier as a 3200. So just set FSB to 200 and you should be ok. If I'm not mistaken the 2800 uses 11.5 (please correct me if I'm wrong) and if IT is locked then you wouldn't be able to get a "true" 2.2 3200+??

you are confused. yes they are locking cpus but ...

2500+ = 1.83 GHZ = 11 x 166
3200+ = 2.2 GHZ = 11 x 200

if you change the FSB of the 2500+ to 200, you get 3200+

it doesn't matter if the multiplier is locked. it's locked at the same multiplier as the 3200+

well you8 can always unlock your cpu, if you are afraid of messing up your cpu by doing it via the jumpers, there is also the wire method. The Mod Fathers - Wire Method

No these new cpus are locked and cant be unlocked much like the pentium chips. Theres a great thread at overclockers.com forums about how a member basically fried the chip to see what would happen with the bridges and could not figure a way to unlock it. Anyway thanks for the advice and i guess im goin with the amd.
