    So this CPU should work? Intel Pentium D 925 Presler 3.0GHz 2 x 2MB L2 Cache LGA 775 Processor

  • dirkdevet Sep 19, 2008

    I have the exact same system and am unexperienced in upgrading cpu's. I however would like to maximize the intern memory, upgrade the processor to a dual-core and get the best possible video card. But like everybody I don't want to buy new parts that aren't compatible.



    Thanks in advance for your help.

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

Whomever answered this before doesn't know what they are talking about. What matters is the technology used in the processor. Obviously you couldn't take a 775 Socket processor from a computer made today and put it in your computer. Your computer has to be able to recognize it. Your system most likely has a Pentium 4 (P4) Prescott Processor. I believe all Prescotts are 90nm technology and I know from other websites that the 5100 will take at least a 650 which 3.4Ghz which is no longer sold that I can find so you have to find it on ebay. Hope this helps!

Seems you can not upgrade to C2D due to BIOS limitations, even though C2D chips are LGA775. AND(!!!) because the Motherboard on these machines is mounted on the wrong side of the case, you just can't get a new mobo that accepts your C2D processor and ram.

Can't boot up Dell 5100 Dimension, amber light flashes


When you mean the amber light, is that the blinking hard drive access light or the power light? Different cases have different colors on it. Mine has blue and green lights.

If you see the boot screen (bios) and then after it goes to boot, does it blink and hang?

This could be a simple operating system issue, hard drive or hardware/motherboard issue. If you could provide more information, that would help.

Graphics upgrade needed


the computer has one PCI-Express slot (x16) which will take most of the latest video cards out there.

All you have to worry about if you buy a brand new card for it, in the 200-500 price range is does your computer have a good enough powersupply?

the computer comes with a 300W powersupply, which you might need to upgrade to w500 or more,

600W powersupply
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171036

that one will go a long away, you should be able to keep the powersupply even if you decide to upgrade the cpu/memory and the motherboard, making it a brand new computer, the powersupply has enought juice to power it.

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=ati+radeon+4830
theres a 512MB and 1024MB cards. look around for cheaper deals if you want a smaller card with less memory.

Power supply ?


I'd recommend purchasing a new power supply.

Your Dell Dimension 5100 comes stock with a 305W power supply. This is a bare-minimum wattage that will only handle what they ship on the system & not much more. You're better off upgrading the power supply with a compatible after-market model.

You can go to a PC parts store in your area and take your chances...but they're usually more expensive then Internet sources (they've got to pay for their brick-n-mortar store overhead).

Here's a link for a very inexpensive replacement 400W power supply for your Dell Dimension 5100:

http://www.affordablesurplus.com/dell-5100-5150-power-supply.asp

This particular site offers $8 Flat-rate shipping & a 1 year warranty. Your power supply is only $49.99 - you might be able to find it cheaper elsewhere, but that's the best I could find with a quick Google search.

If my answer helped you, please provide feedback :-)

Good luck!

Upgrade


according to this cnet.com (http://reviews.cnet.com/desktops/dell-dimension-5100-pentium/4505-3118_7-31429803.html) 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.
