Changed notebook CPU, got memory problem?

[Rovillalob]

I tried changing my dell N5010 CPU (Pentium P6000) with a I5-3320M to see if they were compatible as I found mixed answers on the internet. The pentium CPU uses the PGA988 socket while the I5-3320M uses FCPGA988, hence my question. Anyway when I turned it on I got 3 short beeps with a black screen, according to my research that means "Failure in first 64k". I swaped it back to the P6000 and it booted as expected. 

This only brought more questions, what are the differences between those sockets? is there a way to fix this issue? will it eventualy work?

There is no actual difference both are flip chip land grid arrays (fclga) it could be not supported on your motherboards bios.

How can I know if it's supported? There is no info in intel's site (i belive they builed it)

It's not supported. P6000 was Arrandale, which is gen 1 of the Core i architecture. Meaning that Ivy Bridge i5 you bought won't work at all since the motherboard won't recognize it. Ever.
