    Can you put a P8400 in an dell inspiron 1720?
    The FSB is 1066, will this just down clock to 800 or is it just not gonna work?

    It's just not gonna work. Get a T8100 or T8300.

    I think it might work. The 1066mhz FSB cpu's can throttle FSB. I would give it a try if you can return it.

    Well, if you've got one lying around or can borrow one, try it out. Though, I'm pretty sure your notebook won't even boot.

    The chipset supports a FSB of 200MHz max, so the CPU's frequency will downclock accordingly.

    Better to get a T8x00.

    It's not about throttling. I believe its lack of hardware and/or BIOS support. It's just not configured for those CPUs.

    Theoretically it won't work at all and because of BIOS support and to the extent of the chipset not even booting along with it. I have heard cases where people have tried installing these processors onto Santa Rosa machines and it failed to boot completely.

    The Inspiron 1720 uses a GM965 chipset.

    But on the other hand, alot of people tell me that 6GB RAM doesn't work in that machine but it did in the end with BIOS A09. Likewise for your case perhaps no one has tried before, so if you on have a spare 1066Mhz FSB processor lying around, still it doesn't hurt to try. There's still no 100% concrete evidence that it won't work anyway.

    But my advice is to go for the T9500/T9300 processors instead.

    Santa Rosa supports 8GB of memory, in most cases, it's the BIOS that limits the amount of memory.

    Exactly. The 1720 is however limited to 6GB unfortunately.

    ok, so i'm going for a t9500/9300, t8300/8100, or even a t7800. i prefer the larger l2 cache size for what i'll be doing (analysing large sets of volume data) so probably will probably avoid 8000s unless there a lot cheaper. I think i still with the t2390 for a little while until i can find something at a good price.

    I was reading some intel spec on mobile 965, which i'm assume IS santa rosa (but could be wrong). http://www.intel.com/Assets/PDF/datasheet/316273.pdf

    it says clear that the chipset can only support up to 4GB! luckily we have people like SomeForOfHuman who are willing to test these limits and i've ordered a 4GB chip http://www.supamedia.co.uk/product/C-VS4GSDSKIT667D2.htm
    and fingers crossed will have 5GB ram once the chip (and the laptop) get here. Unfortunately im not going to be buying a p8400, just to see if it'll work.

    By the way, I've ordered a second drive. An ebay seller told me i could mod a caddy#1 to fit in a caddy#2 bay, that was much cheaper so i ordered one. has anyone else managed this?

    That's an old document, before 4GB SODIMMs existed. Intel has updated their datasheet saying it can support up to 8GB. This topic has been discussed thoroughly and several users have already done this. Machines that have successfully done it (you can even search them in this forum) are: Lenovo T61 (screenshot example below)/X61, pretty much every Dell (XPS, Inspiron, Vostro, Latitude, Precision), Apple MBP
