The Dell N2828 motherboard is supposed to have the Intel 865PE motherboard chipset on it.

Looking at the - List of Intel Chipsets - on Wikipedia, we can see that the maximum FSB supported is 800MHz,

[Scroll down with your eyes to 865PE, then read across ]
Dell Support lists that the Dell Dimension 4600 series, can have either the Intel 845G motherboard chipset, or the Intel 845PE motherboard chipset.

As seen in the chart the Intel 865G motherboard chipset, also supports up to an 800MegaHertz Front Side Bus.

The processor socket is a Socket 478.

I see that, (Surplus warehouse) has Pentium 4's available with an 800MHz FSB.

Looks like the best they have is a Pentium 4 at 2.60GHz, 512MB cache, 800MHz FSB for $18.95 (US. They're located in California)

Not advertising for them, just sharing,

Scroll way down the list to the heading - Socket 423/478 (Pentium 4/Celeron), then go towards the last of the list.

[To expound:
The motherboard chipset is the Northbridge/Southbridge chipset.

Chip and Chipset are slang terms for I.C., or Integrated Circuit.

This motherboard diagram, may help explain how the motherboard chipset comes into play,

You can also look up the terms listed, by typing them into the Wikipedia search box, then clicking on Search.

You may be interested in looking up;

1) Northbridge (computing)
2) Southbridge (computing)
3) Front Side Bus
4) Internal Bus
5) Super I/O
6) Comparison of Nvidia Chipsets
7) Comparison of AMD chipsets
9) PCI Local Bus
10) PCI Express
11) GPU
12) Comparison of AMD graphics processing units
13) Comparison of Nvidia graphics processing units
14) Intel GMA ]

Anything listed in blue, is a link to more information about it. Just left-click on it.

As you can see in the chart, the Northbridge chip handles the high speed processes of a computer.
Such as the Processor, Ram Memory, and high speed graphics.

AGP and PCI Express being high speed graphics. Any graphics card inserted into a PCI slot is Not high speed graphics.

The Southbridge chip handles the slower processes of a computer.
Anything to do with PCI, or Integrated Graphics, being two of the slower processes.

Therefore if you know what Northbridge chip you have on the motherboard, and what processor socket, you are pretty well on your way to know what processors your motherboard supports.

The Northbridge chip is under that 'meat cleaver' looking heatsink next to the processor socket.

If the heatsink were removed, and any thermal paste also removed, you would see - Intel 82865PE stamped on it.

Not a good idea to remove the heatsink, without having fresh thermal paste to replace the old thermal paste with, PLUS the top of the Northbridge chip, And the bottom of the heatsink needs to be THOROUGHLY cleaned Before applying new, fresh thermal paste.

The Southbridge chip has Intel ICH5, or ICH5R on it.

Dell dimension maximum cpu upgrade

This desktop has a motherboard in it that has an intel LGA 775 processor socket in it. From the spec's I found the cpu that ships with the system should be able to scale up to 3.5 Ghz. But you should be able to replace it with any Pentium 4 that fits into an LGA 775 socket.

Upgrade cpu

It is a bit of a crapshoot trying to upgrade a processor from a major manufacturer. Their motherboards are designed specifically for the manufacturer and documentation on exactly what will work NOW compared to when the unit was new is rather hard to come by. They don't support people upgrading very well compared to the aftermarket manufacturers.

You should go to and put in your service tag to check your exact configuration yourself before spending any money.

According to Dell, the Dimension 5150 has a motherboard that uses the Intel 945G Express chipset. You can see INTEL'S documentation on that chipset's capabilities here. According to that documentation you can use a socket LGA775 with up to a 1066 MHz system bus speed.

Looking at Newegg, the fastest LGA775 processor with 1066 MHz are a 2.93GHz Duo core or a 2.4 GHz quad core. Again, no guarantees either will work with your system, and you definately want to make sure your power supply and case cooling are up to the task.

according to this ( the dual core is not an option. I'm not sure if that means that Dell doesn't offer an upgrade, or if it's not possible. First, open your tower and look over the Motherboard for the manufacturer and model. Once you have those, google them and look for the specs of what cpu's are supported by that motherboard. If you can and do decide to upgrade, check with the CPU manufacturer to see how strong of a power supply you need for the more powerful CPU. You're might be ok, but you might need to upgrade the PSU (Power supply) with the processor. From your description, I can't tell what motherboard is in your Dell. That will be the limiting factor. Get the motherboard specs and you'll know what you can do.
