CPU upgrade for Compaq SR1220NX Desktop Computer


Hi
The specs for this machine state that it is a motherboard with
"Socket 478 for Intel P4 Williamette and Northwood processors
Supports Intel Pentium 4 processor up to 2.8 GHz
Supports Intel Celeron processor up to 3.06 GHz (Prescott based Celeron with 533MHz FSB)"
In other words, any CPU that is not socket 478 ( a fairly old socket now) will not even fit on the board. You do not mention your current CPU so you need to compare it with the spec above to see if you can improve it. It is an old machine/motherboard, so your money might be better going towards a motherboard or system box upgrade.
Cheers

Need to upgrade cpu for using multiple progams at on time, can cpu be upgraded on this older model compaq presario S0000 / 8000 series computer


As you have stated it's a Compaq Presario S0000/S8000 SERIES desktop computer.

One of the S0000/S8000 series.
Without knowing the exact model number I have no idea of what hardware is installed on the motherboard.

On the back of the computer tower, or up on the side, is a white Service Tag.
P/N = Product Number. This is the exact model number I need.

Also; Going to HP Support with the exact model number may not reveal the info I need, either.
They may not list the specifications, and therefore the installed hardware, for your computer.
There is an easy way around this, however.
Use CPU-Z from CPUID.com

What info is needed in order to know if the Processor can be upgraded:

A) Processor Socket: What processor socket is installed on the motherboard. This is what the Processor sits in.

Just two examples for Intel processors; Socket 478, and LGA 775 processor socket.

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

With this style of processor socket, the processor socket has the socket holes, and the processor has the contact pins. (478 holes/478 pins)

2) http://en.wikipedia.org/wiki/LGA_775

With this style of processor socket, the socket has the pins, while the processor has contact pads.

There are other styles of Intel processor sockets. There are also AMD processors which can be used, and have many different processor sockets also.


B) What motherboard chipset is used.
Specifically, what Northbridge chip is used.

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

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

For your motherboard the motherboard chipset is a Northbridge chip, and a Southbridge chip.

{So aptly named Northbridge, and Southbridge, for the relation of how they sit on the motherboard.
Looking at a motherboard as if it were a map, the Processor sits to the North.

The Northbridge chip sits close to the Processor.
The Southbridge chip sits to the 'South' on the motherboard }

The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and High-speed graphics.

The Southbridge chip handles the slower capabilities of a computer.

4) Motherboard Diagram,

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

Knowing what processor socket is used, and what Northbridge chip, we can accurately determine what processors are supported.

CPU-Z is a tiny, free program that without opening your computer, tells you what hardware is installed on your motherboard.
Tells you what processor socket, and Northbridge chip are used, for one.

5) This is information on CPU-Z. Shows you a screenshot of the user interface of CPU-Z,

http://en.wikipedia.org/wiki/CPU-Z

Left-click on the CPU-Z user interface to the upper right of the page, to enlarge it.
(Under the bold CPU-Z heading)

When CPU-Z opens it automatically opens to the CPU tab.
(Central Processing Unit. Another term used is Microprocessor, or simply Processor for short)

To the right of - Package - tells you what processor socket is used.
Clicking on the Mainboard tab tells you what motherboard chipset is used.

6) CPU-Z download page,

http://www.cpuid.com/downloads/cpu-z/1.56-setup-en.exe

Left-click on Download now! in the purple rectangular box.
A small window will come up on the right side -
Opening cpu-z_1.56-setup-en.exe

Left-click right on Save File
Another small window will come up on the left.
In the header at the top of this small window, tells you where the file will download to.

In the wording may be Desktop, or My Documents, or Downloads.

Desktop: The file will be on your desktop screen.

My Documents: Left-click on Start, then on My Documents

Downloads: Left-click on Start, then on My Documents. DOUBLE-click on Downloads.

When you see the file name DOUBLE-click right on it.
Follow the easy installation instructions.

Go back to your desktop screen. Double-click on the CPU-Z icon.
When CPU-Z has loaded, come back here in a Comment, and tell me;

1) In the CPU tab, what is stated to the right of - Package

2) Left-click on the Mainboard tab.

What is stated to right of;
A) Manufacturer
B) Model
C) Chipset
D) Southbridge

Evo d510 small form factor with 1.79ghz processor what other size of processor can i put in


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.

I have intel pentium celeron 1.70ghz 256mb ddr ram, i wana upgrade it to P4, i got 8284g motherboard


8284G tells me nothing unless I want to hazard a guess, and I don't.
I like to post factual information.

8284G could be a pre-built computer manufacturer number on a label, that is stuck upon the motherboard manufacturer's printed model number, on the motherboard.

All pre-built computers have their motherboards made by a motherboard manufacturer, they do not make their own.

Or it could be a printed model number on the motherboard, but refers to the pre-built computer manufacturer model number, that they wanted printed on. Printed on for them by the motherboard manufacturer.

It could be a reference to a part number on a chip of the motherboard. An Intel 8284g which is a graphics controller chip. (Chip and chipset are slang terms for Integrated Circuit, or IC)

http://www.intel.com/support/graphics/intel845g/sb/cs-009072.htm

However though, the Intel 8284G graphics controller chipset is usually used in conjunction with the Intel i845 chipset family.
(845, 845E, 845GL, 845G, 845GE, 845PE, and 845GV)

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

The Intel i845 chipset family supports Intel processors that have up to a 400MegaHertz Front Side Bus. (400MHz FSB), and some of the Intel i845 chipsets will support processors with up to a 533MHz FSB.

So now let's look at the Intel Celeron 1.7GHz processor,

http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors#.22Willamette-128.22_.28180_nm.29

1) Based on the Willamette-128 Core
2) Based upon the 180Nanometer architecture. (180nm)
3) Uses a 400MHz FSB
4) Uses 1.7 Volts (DC)
5) Uses the Socket 478 processor socket. (Processor has 478 pins, processor socket has 478 socket holes)

Based upon the processor information, and processor information only, you could use an Intel Pentium 4 that has a maximum frequency rate of 2.0GHz, and uses a Socket 478 processor socket.
I also believe it should be based upon the Willamette Core. Reasoning is that the Willamette Core Intel Pentium 4 processors, use 1.75 volts.

The next generation of Intel Pentium 4's are based upon the Northwood Core, and the 130nm architecture.
They use 1.475 to 1.525 Volts.

I don't know if you would install one of these Intel Pentium 4 processors, and your BIOS would automatically recognize it, and set the voltage to match. If not, the processor would burn up due to too much voltage.

What would you gain if you installed a Pentium 4 2.0GHz processor?

Intel Pentium 4's have twice the cache that a comparable Celeron does.

Cache. Crude explanation:

You are writing a thesis, and you need more information. The information is located in books, which are in the basement in a box, and there is no light in the basement.

Down you go with a flashlight in hand, locate the box, and look through the books until you find the book you need.
Back upstairs you open the book, and find the page/s you need for your information.

You find that not all the information you need is located in that book, and back downstairs in the basement you go, flashlight in hand.

OR, you press a few keys on your keyboard, of the computer in front of you, and have your information is seconds.

Low cache is the basement scenario.
Large cache is the computer scenario.

The processor cache is a small memory area for the processor. It operates at the same frequency rate as the processor, therefore it is the fastest memory area available for the processor. It is also the first memory area the processor 'sees'.


Ram memory is next, followed by the harddrive. The harddrive is slower due to it being a mechanical device. (SSD or Solid State harddrives are faster than the mechanical IDE and SATA harddrives. Still not as fast as Ram Memory though)

The .3GHz increase, and the cache increase will be a slightly noticeable difference.
Enough to "Write home to mom about?"
Nope. Not IMHO.

You probably won't notice any increase when on the internet, or doing school/business work.
You differently won't notice any real increase when gaming.

To summarize:
The amount spent, and the time looking, for an Intel Pentium 4 processor that is 2.0GHz, and based upon the Willamette Core, just won't be worth your trouble.
Unless someone just gives you one.

Motherboard ID Motherboard Name Compaq Evo


as long as it is a socket 478 processor which narrows it down to P4 or celeron ( P4 being better and faster ) it should be fine.
Obviously it will state what processors it can handle in the computer manual so if you find the manual it should state in there.
I dont think it will handle more then a 3ghz P4
