Windows 7: What CPU for a old computer?

17 Nov 2012   #11

Win 7 Pro 64-bit 7601

As I told you, the motherboard has a socket AND a list of processors it can accept.

The socket is the first limit to what you can install (as you cannot fit a square in a circle duh!), then there is your motherboard's list of accepted CPUs.

The list of CPUs that the board accepts is the one I linked above, the data was taken from HP's site, I didn't made it up.
If you buy and install a CPU not in that list, it's not going to work, period.

If you bought the components and assembled the PC on your own instead of buying already-assembled PCs from HP, Lenovo, whatever, the board would accept nearly all CPUs that fit in the socket.

Your list sucks, there are very respectable CPUs with socket 775 (screw Xeons, they are for servers), but the board will be able to use only the CPU currently installed and a few more of the same family. Why? because they don't want you to be able to really upgrade your PC, they want you to buy a new one (possibly from them) if you want more.

If you buy components alone, you can upgrade. If you do, you have already a case and a (crappy) PSU, plus probably some kind of crappy graphic card.

Tell us the budget and we can give some ideas on what you can get for that.

Xeon has an LGA 775. But one of the fastest with that socket is: Intel Core 2 Quad Q9650 Processor 3.0 GHz 12 MB Cache Socket LGA775: Electronics

But you also have to match the wattage from your board.

hello? the board does not support it. It's not a normal board, its supported CPU list is pretty damn narrow compared to normal boards.

Also, 500$ for that!!!! It's a TRAP!

With that money I can get a SLI/Crossfire-capable Z77 motheboard with a I7 3770k plus 16 GB (good brand) ram, or a Z77 board with a i5 3570k plus 16 GB (good brand) ram and a half-decent gaming graphic card (or remove the card and place a good PSU). Either processors can beat it on anything by a large margin even if undervolted and downclocked.

For socket 775, anything costing more than 80$ is overpriced. That is, above 80$ you're better off buying a mobo with a bigger socket and a more modern processor that fits in it as price difference won't be so huge while performance gain will be very significant.
