Processor Trouble

So i have a Gigabyte GA-8VT800 motherboard (http://www.giga-byte.com/Mothe...roducts_GA-8VT800.htm) and i'm upgrading my processor from a P4 1.8gighz 400fsb to a P4 3.0Egighz 800fsb w/ HT.

Well, after receiving the processor, i eagarly plug it into the board and boot to see if it works... and sadly it doesn't. The computer as a whole is running fine itself (just moments before w/ my old processor) tho i'm booting w/o any drives plugged in and only one stick of RAM. I try switching a couple other sticks of RAM to no avail. Finally I take the processor out, bring it to my friends computer who's running a computer w/ similar specs and he boots fine w/ the processor.

So the processor's not at fault... i can boot fine off of my friends processor (P4 2.4gighz 800mhz fsb w/ HT) so i know my motherboard's fine... anyone help me understand why the 2 wouldn't be compatible? O yea... i bought both the mobo and proc off newegg...

o yea, when i mean the computer booted to no avail i got NOTHING, not even bios... LCD monitor didn't even pick up the PC was on... didn't flicker the slightest

at first i was thinking something faulty w/ vid card but friends processor in my computer proved wrong
 
Welcome to the Forums 🙂 According to Gigabyte's CPU-support chart, the 8VT800's don't support the Prescott-core 3.0. Maybe pick up a Northwood-core CPU or a mobo that is confirmed to support your Prescott, whichever you prefer?

Side note: you'd better have a respectable PSU to power it with, the new CPU is going to demand more of your PSU than your old 1.8 did. If you need a suggestion, an Enermax Whisper II 460W would be good for that CPU plus any video card on the market, along with a boatload of drives.
 
Checking the gigabyte web page show that your motherboard does not support the prescott core P4's.


Gigabyte compatibility list

His 2.4 will be a northwood core which your motherboard does support and his motherboard obviously has support for the prescott core.

Not much you can do really either get a northwood core P4 or a new motherboard (it should not be too hard to get a northwood core P4).
 
Yep, you need a Northwood. A P4 3.0C specifically to match the Prescott you've got. You also want to get new ram if you don't have PC3200.
