Hello all, I came upon a great buy on a P4 3.4 chip, however knowing how many different ones there have been I only know that it is for the 478 MB's, and has an 800 FSB.I've read all the numbers on the chip but have NO idea how to decifer them . . . any ideas where a site is that can tell me which one this is, or do any of you know? On box..........P43400E478-NOn chip.........7629A764on chip.........6630B089on chip.........0596Any ideas anyone? Thanks in advanceClay

Hi all, ..... agin, Well, CPUZ tells me that it is a Prescott core, and in attempts to overclock it, so far with no great effort we are at 3.62, which isn't even making it breath hard . . . I had forgotten that CPUZ would give me all that infoClay

It may not be breathing at all from the heat :-lol Those Prescott's were like a mini-furnace. Be careful to have sufficient case ventilation or use water.Regards,Jim Karn

Jim, The case has 6 fans drawing in cold air, the CPU has the largest Zalman cooler on it they make, the GPU has a thermalake Pipe cooler with 2 fans built in, and with this new CPU, running flat out with FS9 over NYC, (aerosoft's manhatten scenery), I'm getting 46C on the core..........LIKE I SAID, IT AIN'T EVEN BREATHIN HARD!But yeah, I'm a freak on watching temps and stuff, MB shuts down everything at 55C, so I think I'm safe.Best to you and yoursClay
