opterons vs xp's

what is folding preformace difference between the 2 cpu's? I'm going to be doing some upgrading to my server and was looking at dual athlon mp's but I noticed that a dual opteron board wasn't that much more so I got to thinking if it's not too much more I could just demote most of the server's hardware to a another diskless node and just start out with just one opteron and get another later.

    if they are the same mhz then there shouldn't be much difference at all.
    I will probably never own an operton ...but I have sneaked a peek at the new cray xdi and it uses 12000 opertons ...is that folding horsepower or what?

    well thats not worth it to me then probly just keep what I have for awhile and just focus on more diskless clients. I have to rma board back to newegg and sold a tbird 1.4 I had next I will need another stick of ram and psu and I think I wll use a xp2400+ then I will have node #5 up and running.

    have you thought of unlocked mobile procs?

    Yeah res, the mobile XP's are the way to go, if your mobo can run Barton procs and you don't mind spending a little more money on the proc.

    well what boards I have been running are biostar m7vig proD's They are great for pxe booting but not really good overclocker and lack multiplier adjustment or vcore but fsb does have 133, 140, or 166. I figure a 2400+ ought to be able of handling 2.1 ghz with default multiplier and vcore. I have rack setup for 10 nodes but have space for another 2 or 3 if I ever get to that point. Part of my stratagy is I want to sell the xp's I have and get new ones even if their just 1800+'s except for the server one thats a newer one already.

    You can always hard code a high multi either by the L3 bridges or by using the wire in the socket trick with the mobiles. The nice thing about them is that their default vcore is set at 1.575v sensed by a desktop board and will overclock to at least 2.2 with that setting, in my experience with 2 XP2400m's and 1 XP2600m. That means they will be easier to cool.

    EDIT: Also, I just borrowed a Biostar M7NCD Pro from a friend while my Epox board is being RMA'ed and it's not a bad board at all for a cheapo nf2 board, but no integrated video. It has fsb in 1 MHz adjustment, vcore and vmem in bios. And their cheap, Newegg was running the non-pro version for sale in the refurb dept. for $31.

    thanks for the advice. I couldn't find much info on the M7NCD. It appears that there is doesn't have support in the kernel for the lan. it probly would work with the newer kernels but not sure exactly how to build a LTSP kernel. I can build a kernel for my machine but these are a little different but there is a M7VIZ and uses via KM400 and is same lan as what I have now. Maybe it has better oc abilty than M7VIG
