I am not well versed enough to understand what my upgrade options are with my current Dimension 8400 system. I have a P4 3.4Ghz processor now. Not sure on the motherboard.

Considering updating this PC...this is not a discussion of buying a new one instead. We have a rotating hand me down computer hierarchy system in my house..haha. This P4 system is replacing an older system elsewhere and I am getting a new XPS410 system. Just looking into what my options are to minimally update this P4 system beyond memory etc.

thx

Okay so what I'm seeing is a Dell Dimension 8400 (much like mine) with a P4 3.4, 1gig of RAM and a 925X mobo. Based on that you can't do much without replacing other stuff. The mobo is limited to P4 and cannot use a PD or Core 2. The good news is, I just found out that the mobo in this system is a standard ATX mobo and can easily be replaced. With that info you could buy a cheap 965 board and a Core2 E4300 for relatively little money. What graphics card is your 8400 running? This would help a bit.

I wouldn't be so enthusiastic to say that this mobo is standard ATX. If anything it's mATX, and it's not exactly standard. The 8400 uses the clamshell case, so its front panel wiring will have to be dealt with. Also, the mobo tray itself is not exactly a mATX layout, as its screw holes seem to be in the wrong spots. A mobo tray out of the lesser 4xxx clamshell cases were mATX compatible, but the 8xxx series tray design is unique.

Sweet , I use the same handme down system in my home. Whoever is getting the 8400 is probably used to something lesser so just getting it should be enough for them. If anything a video upgrade, if the machine is going to be used for gaming, before passing mine down I had a 7900GTO in it. I sold it to help pay for the 8800 I have now and put the 6800 back in it. The machine it replaced was a 4700 with X300 video so my son was more than happy with his upgrade.

Okay so who is wrong here: Dell 8400. MPilch seems to believe that it is standard ATX as well. We could be completely wrong, but I would just like a difinitive answer. I know for a fact, since I have one, that the 4700 uses a mATX mobo. I just don't know about the 8400. I'm not saying you are wrong, but I am getting conflicting answers! :lol: 
April 11, 2007 11:19:28 PM

MPilch is quite knowledgeable about power supplies, but when it comes to this question about Dell computers, I'm afraid he's mistaken.
April 11, 2007 11:38:20 PM

Yeah, I did some research on my own. everything points to him being wrong on that. It kinda sucks because my future upgrade options are now limited. Any idea about the dimension 4700 mobos?
April 12, 2007 12:25:50 AM

PERSONAL experience speaking here!

Be careful...because some of Dell's PSU's are NOT ATX standard! They use the ATX connector but have some of the wires changed around in the connector pinout!

They did it so that you'd have to use Dell PSU's... Which leads into the second thing I found out...

Dell PSU's has a different screw hole pattern than an ATX PSU so you can't just drop in an ATX compliant PSU.
April 12, 2007 1:56:43 AM

That stopped being the case around the years 2000-2001. All the Dell PSUs thereafter can safely be assumed to be standard design pinout.

Dimension 4700s use the smaller non-clamshell case, which is very easy to use for an aftermarket mobo swap. They have no mobo trays, just mobo standoffs like in regular cases, and the layout of the standoffs is 100% mATX, meaning any aftermarket mATX board will work. The IO panel on the back even pops right out and the new one for the aftermarket board pops right in place. The factory Dell PSU can be reused if desired, or you may upgrade to any aftermarket PSU as you see fit, as the non-clamshell cases use a completely open rear panel area for the PSU. So, the only thing necessary for the Dimension 4700 modification is to rewire the front case connectors, which is pretty simple to do in that style of case.

That's exactly what I was looking for. I'm going to college next year and I am either getting a laptop or upgrading my 4700 as much as I can to make it last a year or so until laptops settle out. I want a laptop but too many things are changing with them at the moment (Santa Rosa, DX 10 support) so an upgrade seems more likely. It would just be for a year or so, so only minor upgrades are needed.
