I recently decided to upgrade from my P4 2.53 (533MHz) to a P4 Prescott 3.4 (800 Mhz). I have (had) Abit IS7-E2 motherboard and after checking for compatability did not hesitate to swap processors. After the swap the system posted and a few seconds later system shut down. Even though I did reset the CMOS I did not even get a post with my old processor. Does anyone know if the mobo is fried along with the CPU and memory or just the mobo? Thanks for the info.

More than likely just the motherboard...but only way to tell is to test with other know working parts..and then test your parts on a known working board.

probably a FSB issue- are you sure you reset CMOS properly? i had a similar problem when upgrading from a 533MHz FSB Celeron to an 800MHz FSB Prescott a couple of years ago- turned out i needed a new MoBo as the one i had didn't support 800MHz FSB, but apparently yours does, so i'm not sure what the problem is...what about the PSU? definitely sufficient power to run that greedy Prescott?

I am pretty sure I reset CMOS properly. I even took the battery out for about an hour. I now think the reason why I fried my MoBo has to do with the voltage settings. I don't think the ABIT's IS7-E2 can function with 90nm CPU's, it was designed for 130nm process. Hence the voltage settings are different. I ordered a new MoBo from MSI (Neo-2 Platinum Ed) and, hopefully, it will post. I am just concerned about the CPU and memory which may have gotten fried in the process. Also I have an Antec 500 Watt PSU, so it should, in theory, be able to handle Prescott (hopefully).
