    My parents had an amd 800mhz that never registered right on their compaq mobo. So sometimes it woul show as 600mhz. Anyway they wanted xp and they only had 128mb of ram and wow it was ungodly slow. They use aol and with xp it would take over 10 mins to load and sign onto aol using cable modem. So after they cracked I bought them 2 256 pc133 and now its actually fast. On windows 98 and like wise Me it was not as apparent witht he different amounts of ram. Offcourse it helped but was not like night and day.

    I'm surprised that you would find a 1.2 p3 overwhelming in power consuption..... it's a pretty efficient processor..a little choked with a small l2 cache & small busses, but efficiency is one of it's stronger points.....nothing like a p4 in consumption....what else is on your system?

    I would look at the rest of your system before going down to a 466 celron.... can't say if cf will be ok, XP will run... Iguidance will run & so will mp3's, but I can see taxing the system with nav & mp3's at the same time....it will be sluggish & may crash at times..... the p3 1.2 sounds like a much better choice..... I would check power calculators before making any rash decissions... I don't think there will be a huge power reduction in what your propousing..... maybe 15 watts or so less in just the processor, if that(I'm guessing though).

    if your after the smaller form factor then get a mini atx for your p3.... I'd switch out other stuff before the procesor if you really need to consume less power..... going from a 3.5" drive to a 2.5" drive will probably get you half way to the difference, without having to severly undercut the processing power available to you now....

    what are you powering it with.... I know an opus 150 should have no trouble with a p3 1.2 setup.......

    I think anything less than a p3 700 is inadiquate for xp in a car... it will work with less, but not to the point that you could say it's good.... at least to me

    Humm... I wonder if you really DO need > 256 MB though. I agree completely that a WinXP machine should have 512MB or up. However, once Windows is loaded then your frontend starts and that is where you will remain. Windows should be smart enough to move most of it's overhead to virtual memory. Much of the OS still needs to be in physical memory of course. The deal is that alot of shell and Explorer items can be moved out of physical memory.

    Just an idea. I would try the frontend before upgrading your ram. 512 will definately help. I'd just be very surprised if it is required.

    Hmmm ever checked task manager while CF is running? I think is bit of memory hog. And when we think u r runnin it on top of windows and is very propable thar u have navigation app like map monkey running too, its also big spender. So i dont think memory requirement is overstatement. I think u carPC could easily need 512Mb to keep all that in physical memory.

    Well, I will be going from a p3 1.26 ghz, full ATX with pci SB audigy, ATI Radeon 7000 agp card, 2 3.5 HD (I know this is taking up a bit, getting rid of 2nd drive regardless), CD-rom, plus powering the 7" touch off of it, plus about 3 or 4 usb items.

    I would going down to a Celeron 466 cpu, MATX with onboard video and sound, 1 3.5" HD, plus the usb and touchscreen.

    I plan on going to a m-itx system eventually, I need to get rid of some of my current hardware (P4 1.7, Celeron 2.0) to get some cash.

    BTW, another reason I am wanting to switch is because the Full ATX is causing space problems, where the MATX is much better. Ive got a p3 733mhz that would go on the board, but it appears dead, even after updating the bios it doesnt respond correct.
    2000 Sunfire build 100%, or is it ever really 100%?

    get a m atx for the p3 1.2 w onboard video..... maybe get one larger 3.5" drive instead of two..... usb sound uses less power than pci I think,,, the p3 1.2 is ideal if you don't want to go to mobile processor & spend $$$

    I stand corrected. I would still recommend that he/she try with 256Mb first. No reason to purchase more if the performance is tolerable; not immediately at least.

    Oh actually wasnt reply to ur post... i wrote that completely independently and only afterwards realised that i was saying quite opposite than u earlier. My post was more about general griping about CF memory consumption than actually answers or instruction to anybody. I completely agree with u that he should try with 256 and i think its enough to make it work... allthough i think programs will not fit completely to physical memory with that setup.

    Im running an EPIA M10000 w 512 megs of ram with CF and iguidance on XP...and when i have both CF and iguidance running dvd and video playback is impossible to watch...very choppy....and CF performace over all has a lag to it...but when iguidance isnt running...system runs fine..more memory the better i guess?

    I run CF on an 800mhz Via board with 128mb of PC100

    Indexing takes forever, but I only have to do that once in a blue moon.
