Re: upgrade

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.

Can i up grade my single core cpu pen4 550 3,4GHz to a Quad core or dual core either one would help

Depends on the socket type.. Socket 423 and 478 do not support core duo or quad core processor types. However, if you have LGA 775 (aka socket T) your motherboard will support the following:
Intel Pentium 4 (2.60 - 3.80 GHz)
Intel Celeron D (2.53 - 3.60 GHz )
Intel Pentium 4 Extreme Edition (3.20 - 3.73 GHz)
Intel Pentium D (2.66 - 3.60 GHz)
Pentium Extreme Edition (3.20 - 3.73 GHz)
Pentium Dual-Core (1.40 - 3.33 GHz)
Intel Core 2 Duo (1.60 - 3.33 GHz)
Intel Core 2 Extreme (2.66 - 3.20 GHz)
Intel Core 2 Quad (2.33 - 3.00 GHz)
Intel Xeon (1.86-3.40 GHz)
Intel Celeron (1.60 - 2.40 GHz)

What is the maximum limit of Processor my OPTIPLEX GX26- can support? i have currently 2.4ghz processor working and i want to now what is the max limit i can upgrade it to, can i place intel core duo?

Sorry, the GX260 can not support a intel core duo. The processor sockets do not match the motherboard.

Also, it can handle any pentium 4 processor that uses an 800MHz bus speed, because the highest bus speed that the GX260 motherboard supports is 533 MHz. The fastest processor available for the GX260 is 2.6 GHz.

Here are the tech specs:

I have a dimension 2400. the current processor is a pentium 4 2.2 can i swap the processor with a intel core duo ??

After checking the specs of this here :

i can confirm that a intel core duo would not be supported without changing the motherboard, and probably the memory too.

Earlier i had ASUS P5G-MX motherboard & 2.0 GHz Core 2 duo Processor.I upgrade my Motherboard to Asus P5KL-AM/PS & then i have a black screen with my 2.0 ghz processor, But i tried 2.8 ghz Core 2...


The only Thing To Do, is view both Motherboards, user Manuals.
To see The boards CPU Support List.
It could be to do with, certain Motherboards Supporting, certain CPUs.
I.e a 533mhz cpu, would not run on a Motherboard that supports 400mhz. The Systems Bios, May cause Other Problems.
If your getting a Black Screen, is it a possible Graphics/Ram Problem, Rather Than The CPU ??

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.

Cpu upgrade dell dimension 5100

Hi, according to the Dell website you have a LGA775 socket on your motherboard. Therefore, you can only buy processors that fit into this socket. Here is a list of some offered by Intel that will work: Celeron D 325 2.53 GHz Celeron D 330 2.66 GHz Celeron D 335 2.8 GHz Celeron D 340 2.93 GHz Pentium4 520 2.8 GHz Pentium4 530 3.0 GHz Pentium4 540 3.2GHz Pentium4 550 3.4 GHz Pentium4 560 3.6 GHz Pentium4 570 3.8 GHz The processors that won't work are the ones that are not compatible with this socket. Everytime you look up a cpu it will tell you which socket it is designed for. To buy a cpu you will need to decide: The brand you want. The speed of the cpu that you want. Extras i.e. Hyperthreading, etc. How much you are willing to pay for it. Then you can narrow your search as you stick within your limits. Let me know if you have more questions. Good Luck
