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.

Want to upgrade my HP TouchSmart IQ504 Desktop PC 2.0GHz processor for a 3.1 ghz ?

First, have you ever changed/upgraded a CPU? It take quite a bit of research to upgrage. If you look at this spec of the Mobo your options are very limited, The Mobo only supports 2 different type Processors, 1, Core 2 Duo (Merom); , 2 Core 2 Duo (Penryn): If you have a 64bit OS consider a memory upgrade, if you haven't already.

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)

Can I upgrade my CPU to an Intel Core 2 duo 1.7

You are basically limited to what was optional on the model. So you can only upgrade to one of the following cpus:

Intel Pentium M 745 (1.8-GHz) with 400-MHz front
side bus (FSB)
Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB
Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB
Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB;
operates at a lower temperature than other processors
Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB
Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB

And you are limted to 2gb of ram max on this model.

Need a prossesor for motherboard

You can also use any other intel 775 socket processor as well. The dual cores are at the top of the list for performance that are compatible with that board, but if you're looking for a cheaper solution, I have that board with a 3GHz pentium 4 and it runs great. Here's a list of all the processors you can use.
Intel Pentium 4 (2.66 - 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)
Intel Pentium Extreme Edition
(3.20 - 3.73 GHz)
Pentium Dual-Core (1.40 - 2.80 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 'Core' Celeron (1.60 - 2.40 GHz)

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.

Re aspire 7104 being upgraded to duo core processor

No it cant be updated

Your acer aspire is based on the 910GML chipset

The Mobile Intel® 910GML Express chipset is optimized for the Intel® Celeron® M processor.

Here you can compare the 910gml chipset and 945 which is used by the core 2 duo.,7419&familyID=7&culture=en-US

As you can see on the page there are key difrences between the chipsets other runs on ddr2, yours on ddr. the FSB support is 400 on yours and 533 / 667 on the 945.

also you can see the supported processor familys right there.

you can look for a
Intel® Celeron® M processor,
Intel® Celeron® M processor Ultra Low Voltage (ULV)

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
