Dell XPS 630i

I have an old Dell desktop computer that I want to re-purpose for some general purpose networking needs. I am trying to find information about my system, but can't seem to figure out much through the Dell web pages. My Service Tag is CM5RQG1 and my Express Service Code is 27461335969. Can someone help me with the following questions:

1. How much memory can my current board manage?
2. What processors does this board support?
3. If I decide to replace this motherboard completely, what are compatible 3rd part boards that will fit this Dell case?

Maximum supported RAM
8GB (2GBx4)
DDR2 PC2-6400 • CL=5 • Unbuffered • NON-ECC • DDR2-800 • 1.8V • (256Meg x 64)
(Also takes the slower DDR2 PC2-5300 • CL=5 • Unbuffered • NON-ECC • DDR2-667 • 1.8V)

Fastest support CPU upgrade from the stock E8400 would be the Q9650 which fits within the same Dell heatsink assembly too.  Make sure you've upgraded the BIOS to the latest available version before replacing it though.

It's a standard ATX board but you'd need to pull the PSU too - I know it's a pretty case but there's a whole lot of extra work in wiring a non-Dell connector board to Dell's plugs!

The CPU it uses now is a core2duo e8500 that uses a 775 socket. You should be able to use any 775 CPU (Core2Quad for example).

As for the board, just open the case and check the markings on the board, how many RAM sockets does it have, and what chipset it uses. Most 775 socket boards take DDR2 RAM, and if it has 4 slots it can probably take 8GB RAM, sometimes also 16GB. But it depends on which chipset it uses. Some have limits of 4GB max.

Changing the board is probably not economical, usually a new PC is the better option.

I was considering either an ASUS Sabertooth Z97 or a Gigabyte GA-Z97X-UD5H board. I had not considered having problems with PSU connections. Are you saying this would be a problem that I would need adapters for?

PSU connectors shouldn't be an issue but the panel connectors may be.  The issue with the PSU is that the Dell system is built to a specific price budget so the PSU output rating is just sufficient for the components in the spec. If you add different components you start altering the power requirements.  

If you are going to upgrade it's likely you're going to get components which have higher demands (although in truth some components designed since the 630's were launched are now more power efficient).  

My main concern would be the other connections to the current board (from the front control panel for example) are bespoke to Dell and you'd need to cut off plugs and rewire - and maybe even extend some cabling because the equivalent pins are on a different position on your new board (both of which should fit this case BTW although again might be a little tight around the PSU box).

Just highlighting that in a project like this it's not always such a simple "modular" swap of parts as it might seem.

Ok that makes perfect sense. I was concerned about the front panel connections but had not considered the pin placements being in different places on the board. Given the amount of time and money I am already spending on this upgrade I will go ahead and look for a PSU upgrade as well.

Thanks for the information and for the link to the 630i forum. It has been extremely useful.
