Question about Dell OptiPlex GX260 PC Desktop

3 Answers

I am looking at an INTEL Pentium 4, 3.4GHz 800MHz 1MB Socket 478 CPU.Will it work in my DELL OPTIPEX GX260(mfd date=10/23/02) machine? I got on SIW to find out that mine is an INTEL Pentium 4, 2.4GHz,(NORTHWOOD),Socket 478 mPGA,Revision: C1,Technology: 0.13um,Instructions: MMX,SSE,SSE2,Original Clock:2400 MHz,Original System Clock:133 MHz,Original Multiplier:18.1,CPU Clock:2397 MHz,System Clock:132.8 MHz,FSB:531.4 MHz,Core 0 Speed:2391.1 MHz,Core 0 Multiplier:18.0,L1 Data Cache:8 KNytes,L1 Trace Cache:12 Kuops,and L2 Cache 512 KBytes.Has INTEL 845G Chipset. I'm sure that I don't know what most of this means,but I figured someone out there with good knowledge of hardware could tell me! THANK YOU! in advance. PS>If this will not work,is there anything that will,or is this already "maxed out" with this CPU? Thanks again. Also,What size PS should I get for this old dinosaur,if I want to do this upgrade for the CPU,and additionally considering the fact that I might upgrade my Hard-Drive to a 250G? My current PS is: Model G20160, output=250W MAX; MAX Combined power on +5V and +3.3V output is 170W. PS-This is the BIG TOWER,Not the MINI_TOWER,or the LAY FLAT MODEL!

    ALSO_I thought I would add this,if info about the MOTHERBOARD is needed,I also got that from SIW. Anyway_here goes: North Bridge: Intel i845G Revision A1,South Bridge: Intel 82801DB (ICH4) Revision A1,CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz,Cpu Socket Socket 478 mPGA,System Slots: 4PCI, 1AGP*****Memory Summary*****Maximum Capacity: 1024 MBytes,Memory Slots: 2,Error Correction: None

    OK Jell_THANKS FOR THE GOOD INFO ON THIS>I guess this old Dinosaur is pretty well maxed out the way it is> I just thought I could help her out a little bit. I read somewhere (On another forum),that the fastest replacement for this was a Pentium 4(NORTHWOOD), 2.8GHZ,and that one is a 533MHz bus,but I don't think that will be much different/make much difference in the actual processing speed(noticeable), to make it worthwhile economically. I guess I will just stick with my P-4, 2.4GHz. HAVE A NICE ONE JELL!!!

  • discipio2 Mar 05, 2009

    Jell_Man that is a great idea! I am excited by the prospect of this. OK-Here comes the obvious question next: "Do you have any idea what board this would be,or better still,if I knew what computers that this CPU came from"...hmmm-lots of possibilities here.I will do some searches on my own Jell, but...if you have any ideas/knowledge about this hit fast-forward! THANKS A MILLION!!!

  • discipio2 Mar 06, 2009

    Hey Jell_Man you are still batting 1.000(in baseball vernacular: "a thousand")! I get paid on friday,and as soon as I do I am going to pop for this stuff,and get started on my upgrade project! VERY NICE STUFF TOO!!! I will keep you up on what is going on with this project, but also if I run into any glitches-I will get on and get some clarification. GREAT PRICES TOO!!! Just add that P-4 3.4GHz! As far as the memory goes-I remember the problem I had on loading those two 1G sticks into my GX260,and getting them to boot up! REM: 2.6V does not equal 2.5V-I guess that means RAM VOLTAGE is important when it comes to getting it right! THANKS BUDDY!!! Here is a great article on RAM. I am putting it here Jell-not for you(YOU ALREADY KNOW THIS STUFF), but in case anybody else reads this-maybe it will help them! THANKS AGAIN MAN-TALK TO YOU AGAIN!!! http://www.web-articles.info/e/a/title/A...

  • discipio2 Mar 06, 2009

    OK Jell_I'm not totally confused yet-but I'm working on it! JUST KIDDING,but...I'm looking at P-4s, 3.4GHz, 800MHz, 1MB, Socket 478 CPUs,and I've been reading about the different cores(Northwood,Prescott,Gallatin),and according to one review the Gallatin is the one to get,followed by Northwood C and then the Prescott E). I am looking for clarification on this. I'm trying to do the best I can for my meager bucks,and I have been pricing out some P-4, 3.4GHz-s,but is it just a speed thing between the versions of these,along with cache size, or can you give me some more info/a page on the net to read? THANKS Jell!!!!!

  • discipio2 Mar 06, 2009

    I just priced out some P-4 EXTREME EDITIONS,and now I know why I won't be looking for one of those!!!

    I just plugged in an INTEL Pentium 4, 3.4GHz 800MHz 1MB Socket 478 CPU into my Optiplex GX270 instead of the original 2.4GHz.

    Bios recogizes the processor as 2.8Ghz instead of 3.4Ghz.
    The thing is that Optiplex GX270 was built when 2.8 was the fastest processor available and I am not sure whether motherboard limits it to 2.8GHz or does the processor still works at 3.4GHz and bios just does not know it...

    For the rest it works just fine and Windows Vista recognizes the processor as for what it is - 3.4Ghz.

I don't believe that's going to work for you.

According to what I've read that machine won't support a CPU with a FSB higher than 533.

Just ran Vista performance index update and it says that processor is 2.8GHz. I guess before that it was looking at the processor code (and identified it as 3.4) but now actually checked the real performance.

Cpu suport


Going with problem heading stating ->

IBM 73P0595 motherboard > CPU Support > and previous problem statement ->
"I have updated my processor from INTEL Pentium d 820,2800mzh 1500mzh to INTEL Pentium d 945,3400mzh....."

Let's take a look at the IBM 73P0595 motherboard specifications, first;

http://www.epinions.com/specs/IBM_System_Boad_W_O_POV_10_100_73P0595_Motherboard?sb=1

http://www.ebay.com/itm/Lenovo-73P0595-ThinkCentre-M50-A50-Motherboard-SOCKET-478-2-4GHz-Intel-CPU-/200870757822?pt=Motherboards&hash=item2ec4d485be

A) Socket 478 processor socket

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

B) Intel 865G motherboard chipset,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4_chipsets

The Intel 865G motherboard chipset DOES NOT support dual core processors.
Does NOT support an Intel Pentium D; 820 OR 945

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_D_microprocessors#.22Smithfield.22_.2890_nm.29

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_D_microprocessors#.22Presler.22_.2865_nm.29

Those two processors also use the LGA 775 processor socket.
(Socket T,

http://en.wikipedia.org/wiki/Socket_T )

What did you base your CPU support on?
Was it the fact that the Intel 865G motherboard chipset, will support Intel Celeron D?

http://en.wikipedia.org/wiki/Celeron_D#Celeron_D

The Intel Celeron D is NOT a dual core processor,

http://en.wikipedia.org/wiki/Celeron_D#Celeron_D

"The Intel Celeron D processor works with the Intel 845 and 865 chipset families.

The D suffix actually has no official designation, and does not indicate that these models are dual-core.

It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M......"

Not the IBM 73P0595 motherboard we're talking about?

OK.

Let's just base it on the statement that you tried to upgrade, from an Intel Pentium D820 to an Intel Pentium D945,

http://www.fixya.com/support/t13549945-update_intel_pentium_d_945_procesor

What motherboard are you using?
Motherboard in a HP Compaq DC7600 Desktop PC?

http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML

Scroll down to the bold subheading -> Processor and Speed

Intel Pentium D820 at 2800MegaHertz (2.8GigaHertz),
with 800MegaHertz Front Side Bus, is supported.
(800MHz FSB)

Probably came with your computer, huh?

Intel Pentium D945 at 3400MHz (3.4GHz), with 800MHz FSB is supported also.

This can be seen by the specifications of the motherboard chipset, also. The Intel 945G motherboard chipset,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_chipsets

Scroll down to 945G in the left column. (Last one listed in chart)

Apparently you just needed the 786D family Processor Microcode Update, or did that not work out?

Awaiting reply,

(How did I come up with the HP Compaq DC7600, anyway?
Did you add it in a Comment, and it has been removed, or what?

Specs on this cpu process


MicroStar International (Inc) Support > 865PE Neo2-P Platinum Edition (MSI MS-6728) Main Support page,

http://www.msi.com/product/mb/865PE-Neo2-P-Platinum-Edition.html

Click on Specification
(Overview / Specification / Download / Support / etc)

CPU (Processor) Support;

1) Intel Pentium 4 processors that have;

A) Use a Socket 478 processor socket,

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

B) Northwood Core, or Prescott Core

C) Front Side Bus (FSB) of 400MegaHertz (400MHz) for Intel Pentium 4 processors that are based on the Northwood Core.

D) FSB support of either 533MHz, or 800MHz, for Intel Pentium 4 processors based on the Prescott Core.

Processors that have an 800MHz FSB can be used, that have UP TO a 3.6GHz frequency rate. ('Speed')
Indication that higher 'speeds' can be supported. (Overclocking?)

Now let's look at Intel Pentium 4 processors, that are based on the Northwood Core, and fit a Socket 478 processor socket,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Northwood_.28130.C2.A0nm.29

(Front Side Bus = FSB
The M/Ts listing means MegaTransfers per Second.
Believed to be a more accurate method of stating the FSB, than MHz.

MegaHertz
Mega = 1 Million
Hertz stands for Cycles per Second. Was named after a man with the last name Hertz.
Example; 400MHz = 400 Million Cycles per Second )

Intel Pentium 4 processors based on the Prescott Core, and utilizing the Socket 478 processor socket,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29_2

sSpec Number will be on the processor, as well as the Part Number.

http://www.cpu-world.com/CPUs/Pentium_4/index.html

Scroll down for photos.

CPU support can be attested to looking at the specs for the motherboard chipset, on your motherboard.

The motherboard chipset is an Intel 865PE chipset.
Intel 82865PE northbridge chip, and an Intel ICH5 southbridge chip.

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4_chipsets

Scroll down to 865PE in the left column.

The part number on the Intel ICH5 southbridge chip, is Intel 82801EB,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Southbridge_8xx_chipsets

The Northbridge chip of the motherboard chipset, handles the Faster capabilities of a computer.
Processor (CPU), Ram Memory, and HIGH-speed graphics.

HIGH-speed graphics is the AGP technology, or PCI Express technology.

Using a graphics card in a PCI slot, or using Integrated Graphics; is NOT high-speed graphics,

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

The Slower capabilities of a computer are handled by the Southbridge chip.

If this is a question of what CPU is on your motherboard at present, and the motherboard is in a working computer, suggest use the free tiny program CPU-Z from CPUID.com,

http://www.cpuid.com/softwares/cpu-z.html

Need to know how to download, install, and use CPU-Z, post back in a Comment.

How do i change the memory bus speed on my dell optiplex 170l? The CPU is an Intel Celeron 2.4GHz. The mother board processor speed is 400MHz and the Bios indicates a memory bus speed of 266MHz and does...


You checked in the right place as far as looking in the BIOS, however, memory and CPU sockets do not necessarily have the same buss speed. My FSB runs at 1066Mhz and my RAM at 800Mhz, it all depends on what type of RAM you buy as to the bus speed. You can up the bus speed on your RAM if you wish to reduce bottle-necking, but I've only done that a few times. In order to adjust anything, you must set the settings to manual. Be careful when you change this stuff around though, voltages must also be adjusted accordingly.

The motherboard chipset of the Dell Dimension 2300 Desktop PC, will not support a processor with an 800MHz Front Side Bus frequency rate.

Only Intel Pentium 4's that use a Socket 478, 1.75 Volts, and a maximum of a 400MHz FSB.

The Intel Pentium 4 HT 3.0GHz processor has an 800MHz FSB, (As you have already stated), and uses 1.475 to 1.55 Volts.

The motherboard chipset for that Dell Dimension 2300, is an Intel 845GL.

This list on Wikipedia, shows you parameters the Intel 845GL chipset supports,

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

Not a good outcome, sorry. Just stating the facts.

New cpu for my motherboard


Hopefully it is compatible.

Here is how you can check. First look up the brand and model of the motherboard. Motherboards are usually labeled with that info.

Next go to the motherboard's manufacturer's website. Search Google using the brand name of the motherboard you should get a website in the results.

Then go to the products information of the website, or the downloads section and look up the model number of the motherboard you have.

You should be able to get specs on what CPU the motherboard supports. Or download a manual with specs.

Comment if you need more help.

Sadly you wont find any 1066Mhz FSB processors for the Socket 478. The best you can find is the 3.4Ghz with 800Mhz FSB. It might be cheaper and also better value for you to get a Socket 775 based motherboard and Core2 Duo processor. The value range E2160/2180 processors or the E4300/4400 processors have been tested to be even faster than the Socket 775 Pentium Dual 3.4Ghz and they also use less power.
