i got a hold of an old dell precision 650. i know this thing is older. but i want to build this thing up anyway. i had some old memory so i put 4 gigs in it. i started installing win7 64bit and get an error saying this is not a 64 bit processor. its a xeon prestonia 2ghz. the main board is model 02K812 with bios ver A05. where can i get info on the best processor for this computer? i know dell's can be hard to upgrade hardware on so i don't want to get something that won't work. old cheap xeon processors are all over e-bay ($10-$20) so i figured getting the best 64bit this thing can handle would be the way to go.
 
well after some research it turns out the max fsb is 533. the socket is 604. that means the best processor for this pc is the SL72Y (Intel Xeon 3.2 GHz) MMX, SSE, SSE2, Hyper-Threading 32 bit. so 64bit is not an option for this pc. intel made a version (SL7AE) with more L3 cache. however i have read this "Many server/workstation motherboards have an E7505 chipset which does not recognize the 2MB cache of the SL7AE"

Yup - a motherboard from that era won't support any 64 bit processors. At that point the only 64-bit processors were Itaniums, and those employ a very different architecture. Sorry! The upgrade path is a bit short.

Depending on how much you use the PC and what it's for, a hard drive upgrade might speed things up a bit.
