This is nothing special, my 2600+ (266 fsb) Thouroughbred B can run these speeds with lower voltages on AIR.

Hi all, I just put my new 2500+ Mobile CPU through its paces and..... Its absolutely identical in performance to my multiplier locked 2500+ Barton. I mean absolutely identical. Results in every test were the same, failed at same points, works at exactly the same speeds and gives exactly the same temps as I was getting too. I cant get any higher overclock despite knocking the multiplier down (in case high FSB was the problem), which tells me I should get my water cooler finished! So, from what I have found with these 2 CPU's, they are the same. Apart from the multiplier lock and the colour :) Everyones experience could be different I grant that. I also tentatively suspect you have more chance of getting a non good overclocker if you buy the Normal 2500+ Barton. The Mobile CPU's must run at stock speeds at lower voltage, so it seems they are cherry picked. Dont let that put you off getting a normal multiplier locked Barton. I havent heard a bad tale of a 2500+ recently. For those that dont know how easy it is to clock a normal 2500+ to 3200+::: Get a NForce2 400 or 400 Ultra board. (I use Abit or Asus these days) Get good DDR400 (PC3200) Ram. (I use Crucial.) Use a known good cooler for 3200+ chips. Plug in, change FSB from 166 to 200MHz (also written as 333 to 400MHz DDR) Voila !!! (its a good idea on NForce2 boards running 400FSB to change the largest Ram timing to 11, seems to help NForce2 boards a lot and u can clock the Ram higher/set timings faster! See reports round the web for more info, I have verified this.) If it fails to run stable, bump the CPU Volts from the default 1.65V to 1.7V, as long as you havent got crap ram, a crap cooler and you dont live in an oven, this will work. In most cases, you can push the cpu much further still. (Neck rests on the chopping block) Grin
