Want to know what would be the best performing graphics card i could install into my compaq evo d510 cmt 2.5Ghz cpu pentium 4/640Mb ddr type ram. i was thinking of one around 128mb or 256mb in size. any suggestions?

I realize that this posted problem is over 4 months old, but in the interest it may help someone;

According to Compaq this is the motherboard used in the Evo D510 Convertible Mini-Tower,

Observe the blue long female connector on the motherboard. This connector is where the 40-pin flat IDE ribbon cable for the Harddrive, plugs in.

(On the above link; it may not work as a direct link. It is a PDF file you download.
In case it does not work just by clicking on it; copy it, paste it into your address bar, press the Enter key )

Scroll the page down to a little more than halfway. Observe the illustration of the motherboard to the Left of the page.
(Has J22, J21, P23, J20, J40, P54, above it)

Look at CR1, CR2, CR4, and P5

Not graphics card, sometimes the processor although HP are usualy keen on intergrating it onto the motherboard...so in short..NO!

here is what you should have. you cant mix mem types. you are suppose to have what is listed below. maximum amount is 2 gig. have to be pc2100 which is ddr-266

Compaq Evo D510 CMT 2GB Memory Ram Kit (2x1GB)

2GB DDR-266 (PC2100) Kit (2x1GB

yes you can.

You can upgrade the speed of the CPU. Of course in order to do that you must know the motherboard capabilities. If the motherboard is upgradable to 2.0ghz processor with the same specs with your 1.8ghz processor then you can upgrade. If the motherboard is un-upgradable, my suggestion is to replace the motherboard, get a new processor, memory module, etc. Meaning you just bought a new computer. For the mean time, upgrade your memory module. Un-install the software that you don't need. Especially the one the eats up the processor speed.

Go to hp site to search for your drivers at http://welcome.hp.com/country/us/en/support_task.html

Hope it will help you.

The Compaq Evo D510's motherboard has a Socket 478 processor socket, and uses an Intel 845G motherboard chipset.

This is information on the Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

As you can see the processor socket has the holes, while the processor has the pins.
478 socket holes.

Only Intel processors that fit into a Socket 478 processor socket, can be used.
Intel Celeron or Pentium 4.

Motherboard Chipset:
The motherboard chipset consists of the Northbridge chip, and the Southbridge chip.
Chip and Chipset are slang terms for I.C.
Integrated Circuit.

The Northbridge chip handles the high-speed processes, while the Southbridge handles the low speed processes of a computer.

The Northbridge handles the Processor, Ram Memory, and any high speed graphics.

(AGP and PCI Express being high-speed graphics.
Any graphics adapter card inserted into a PCI slot, or Integrated Graphics {On-Board), is a slow speed process. Handled by the Southbridge chip)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[CPU stands for Central Processing Unit, or for short - Processor)

This is information about the Intel 845G chipset,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4_Chipsets

Scroll down on the left until you come to -
845G
Read across.

The Nothrbridge chip is the Intel 82845G.
The Southbridge chip is the Intel ICH4.

As you can read looking across, and at the top of the chart, the 845G will support processors with;

1) Celeron, Celeron D, and Pentium 4 processors.

2) Up to a 533MHz FSB. (533MegaHertz Front Side Bus)

(Pentium 4 processors are better than Celeron.
The Celeron was designed as a budget processor.
'Celey's' generally have half of the L2 cache, that a comparable Pentium 4 has)

I felt listing this information in this manner, would help you can make an informed decision, as to what processors are compatible with the Evo D510 motherboard, instead of just stating, "Get this processor".

I will include a link of a website I found some time ago, that sells Pentium 4's with these parameters, at a very reasonable cost.

first problem its a compaq go buy something else no seriously buy something else
check your bios settings F10 for compaq if i remember corectly might be F2

i mean com on 533 bus and dosnt saport multi core cpu's
my 2004 dell 200 mhz buss saports quad core wth
if its not a bios setting replace your keyboard good luck

You need install windows update at least once

U can install nvidia graphics card
