northwood/prescott barton/Ifortget

[wooha007]

i just put together a pc for a friend. powered it up and BAM....nothing. well, the fans did spin i guess. anyway, i've exhausted my faculties on troubleshooting this thing. i don't even get beeps from the pc's speaker to help me out. i've now done some research on the MB (shuttle av49pn ver1.3b) it says on the man. site that it's NOT compatible w/prescott cpu's. i'm trying to use a new (recently purchased) pent 4 3.0g which to my knowleged is northwood. but i've seen prescott/northwood both used in ref. to intels p4 socket478 chips. i've seen them used seperately, what are they all about? also i'm curious about amd's names (bartlett etc.) for their cpu's.

oh, on that trouble shooting for the shuttle board...the ram is known good and so is the agp vid card. i don't have a know good pwr supply however. I guess it might be junk, but i'll get one. i took it down to the bones of pwr sup / ram / vid and made sure i had the cpu's clock speed jumpered right (200mhz i've read from shuttle's website). got any ideas or suggestions?

It's strange because you should always get a beep from the speaker on power-up, in fact the beep will change to help diagnose a problem or faulty/incompatible component. Once you confirm or eliminate the power supply as the problem, try removing one component at a time and powering it up each time.

How much L2 cache does the cpu have? If it has 1 MB it is a prescott. If it has 512 kb it is a Northwood.

Both Norhtwood and Prescott cores were made with 478 pins, so you can't tell the version from the number of pins alone.

I remember an Asus board that wouldn't boot or give any POST beeps to help me figure out why. By chance I happened to plug speakers into the onboard sound and discovered it was "speaking" the error instead.

hey thanks y'all! it turned out when i looked on the shuttle website for this MB that it's not compatible w/prescott processors. the cpu is a prescott (i know now thnks 2 Mnl) cuz it's got 1MB L2 cache. i member cuz i bought it thinkin' i wanted the extra cache and so on i go with this run on sentence.....THanks !

so my next question is if i get a MB that supports prescott processors is it gonna work just fine? or better yet, how can i tell 4 sure whether or not the board supports prescott/northwood or what if it were an AMD chip?

Go to the motherboard manufacturers website, look up the model you want to buy and all the relevant information should be there. You can find all the manufacturers websites by simple googling.
