I have change processor then ibn bios processor detail are not shown?

1.Live with it. No harm should be done. Actually there is a faster procesor in your computer and it works.
2, Update your BIOS. You should find the proper BIOS update for your computer. If any error happens while updating your BIOS, you may "brick" your computer.. It will be converted to a nice decoration piece and conversaton object.

Ahhh.. just another possibility. sounds incredible, maybe you'll say that it's not possible, but maybe you made a mistake and used the old processor or you installed a similar processor to the one you had before?

Dell dimention 2350 socket 478 I upgrade celeron 2.0Ghz to pentium 4 3.0Ghz 530 The Bios show me the speed 1.5Ghz. Bios A02

The Dell Dimension 2350 Desktop PC motherboard, has an Intel 845GL motherboard chipset,
mounted to it. (System Information),

Here we see that the Intel 845GL chipset supports processors, with a -> maximum <- Front Side Bus of 400MegaHertz, (FSB = 400MHz max.),

The Intel Pentium 4 model 530 (3.0GHz. Also has Hyper-threading Technology. HT), operates with a FSB of 800MegaHertz, (FSB = 800MHz),

(Scroll down. Pentium 4 HT 530 )

You can't make the Intel 845GL chipset support a processor with an 800MHz FSB.
BIOS update or not, the voltage range will be too low. Therefore the FSB is low. Changing just the Multiplier will not do the trick either.

(BIOS Setup, Advanced Chipset Setup. Doubt the options of changing the FSB, and/or Voltage, and/or Multiplier, is available with that BIOS program))

Note your 3.0GHz processor is operating at 1.5GHz?

Max FSB supported is 400MHz, and your Model 530 needs 800MHz? (For max operation)

Post additional questions in a Comment.


[ Chip and Chipset are shortened terms for I.C.
Integrated Circuit,

The motherboard chipset technology used for your computer, has a Northbridge chip, and a Southbridge chip.

(Does not apply to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9 processors )

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

[ The AGP technology, and the PCI-Express technology, is High-speed graphics.
Using a graphics card in a PCI slot, or using Integrated Graphics, is NOT High-speed graphics ]

The Southbridge chip handles the slower capabilities of a computer.
Anything connected to the PCI bus, (Such as a PCI graphics card)
Audio (Sound)

[ CPU stands for Central Processing Unit. Another term used is Microprocessor, or Processor for short ]

So it is first up to the Northbridge chip, of the motherboard chipset, whether it will support a certain processor, THEN if a BIOS update will help.

My amd sempron 2800+ 2ghz working now on 1,20 ghz m848a v5.0

Your Sempron 2800+ is working at 1.20GHz?

Let me state this;
The MAXIMUM operating frequency rate ('Speed') is 2.0GHz
This is when the Processor is operating at a Maximum 'speed'.
If it isn't under a full load, it won't be operating at a maximum 'speed'.

Again, if there is no program/application running that demands the full capability of the Processor, the Processor will be idling along.

[A Processor operates at a Frequency Rate. For folks to understand it better it is stated as 'Speed'
GHz stands for GigaHertz.
Giga is approximately 1 Billion
Hertz stands for Cycles per Second.

The maximum frequency rate for the Sempron 2800+, is 2.0 Billion Cycles per Second ]

An AMD processor is 'Double-Pumped'. (In comparison an Intel processor is 'Quad-Pumped' )

The 333MHz FSB is actually 166Mhz that is 'double-pumped'

I don't know which Sempron 2800+ you have.
Thoroughbred- B Core, or Thorton Core.

{Thoroughbred-B Core model has SDA2800DUT3D part number on the top of the Processor's case.
Thorton Core model has SDC2800DUT3D part number on the top of the Processor's case}

Both models fit in a Socket 462 processor socket. (Socket A is also known as Socket 462)
Both models have a 333MegaHertz Front Side Bus. (333MHz FSB)

Both models have a Multiplier of 10 times.
(Under the heading - Mult 1, is10X )

Voltage is 1.60 volts.

PC Chips Support > M848A(V5.0) motherboard,

Under the Downloads heading to the right, left-click on the Manual tab.
Now click on the country nearest yours, ( Taiwan, USA, Europe, China )

This motherboard manual is a PDF file. At the top of the PDF file is the page number box. It is to the Right of the Down Arrow.
Use the Down Arrow, go to Page 39.

In BIOS Setup I want you to go to the sub-menu -
Advanced Chipset Setup.

[When you start your computer, and before Windows loads, there is a manufacturer logo screen.
Right after the logo screen, and at the bottom of the screen, is stated on how to Enter BIOS Setup.
It will state, Hit if you want to run SETUP.

At this time you are supposed to press the DELete key to enter the BIOS Setup Utility.
(Full name for BIOS Setup)

The window of opportunity is usually VERY small. If you do not press the Delete key in time, Windows will load.

I suggest, that AS SOON as you press the Power On button to start your computer, start tapping on the Delete key in 2 second intervals.
This way you won't go past the window of opportunity.

(If you hear a beep each time you tap the Delete key, don't sweat it. It is a Stuck Key Error beep)

Go to Page 35 in the motherboard manual. This shows you the Main Menu for the BIOS Setup Utility.
In the list is Advanced Chipset Setup.
You can no longer use your mouse. In the BIOS Setup Utility you have to use the Keyboard to navigate around.

Use the Down Arrow key to highlight Advanced Chipset Setup.
Press the Enter key ]

In Advanced Chipset Setup the top line is - Detect CPU Frequency
To the right should be - Auto

The second line down is CPU Frequency. (Processor frequency)
For your processor it should state 166MHz.

At the Right side is the Available Options, and at the bottom is the navigation key.
(Available options shows you what options are available for what you are looking at.
The Navigation Key tells you how to navigate around, and how to change settings)

[Using CPU-Z from This is good for looking around, but the BIOS Setup Utility can change parameters, unlike CPU-Z ]

1) Is the Detect CPU Frequency set to Auto?
2) Is the CPU Frequency set to 166MHz?

If so everything is working fine.

If not state so in a Comment, and I'll guide you in setting CPU parameters manually.

When you are looking around in BIOS Setup, it is - Just That.
You are looking around, and have made no changes.

IF you make a change, you have to Save Changes.
Otherwise it will be as if you have done NOTHING at all.

IF you make a mistake in making changes, the computer will not work.
People fear this.
ALL you have to do is go back to BIOS Setup, and set everything back to the way it was, then Save Changes.
The computer will be as it was originally, and will work again.

BEFORE you make changes, write down the original settings )

A Sempron processor is a Budget processor. Also known as a Starter processor.
It is the bottom of the line. (Just like an Intel Celeron)

A Sempron processor has half of the Cache that a comparable Athlon processor has.

The first memory area that the Processor accesses.
The Cache operates at the same frequency rate as the processor does.
It is a small memory area for the Processor.
The more cache you have, the faster the Processor will operate.

The Cache is the first memory area that the Processor accesses, then the Ram Memory, then the Harddrive.

{Ram Memory usually operates at HALF of the frequency rate that the Processor does.
A Harddrive is a mechanical device, and operates MUCH slower than Ram Memory.
Even the solid state Harddrive's}

CPU Support for the PC Chips M848A(v5.0) { M848A version 5},

To the top left of the page is a red rectangle with the heading CPU Support Search in white.

1) Left-click on the blue down arrow, on the right side of the box under - Product Category.
In the list click on - Motherboard

2) There is another box underneath. Left-click on the blue down arrow to the right of this box.
Click on - Socket 462 (AMD.....

3) Left-click on the blue down arrow for the box under - Model
Scroll the list down, click on M848A
{V5.0 will pop-up in the box under Version}

4) Left-click on Submit

You are now looking at the AMD processors, that the PC Chips M848A(V5.0) motherboard will support.

{Where it states Status on the right.
This tells you whether the Processor will work with the current BIOS program, and version, that is on the computer now.

Your BIOS program was made by AMI
American Megatrends Incorporated.
It was made in 2001.
The version is 1.54.B1E

Under the Status heading you will see YES listed for all processors that are listed.
If there were a NO to the right of a processor, it means the current BIOS program would not work with it.
You would then need to upgrade the BIOS program.

Just thought you may want to know }

Why do I bring up CPU Support?
Because I would fly that 'Sempy' processor out the door like a Frisbee at the neighborhood cat.
Just sayin'.

Your BIOS is hosed. This could mean that your BIOS chip has simply failed, or that an attempt to
update BIOS failed, or that a pernicious virus has erased part of your BIOS EPROM chip.
Fix: replace BIOS chip - its a physical EPROM chip on the motherboard.
Why this is nearly impossible for the experienced home electronics buff: modern PC boards,
especially those used in laptops/notebooks/pad computers, where space is tight, are
wave-soldered, and virtually impossible to work on - for even the experienced hobbyist.
Your only hope: the BIOS chip is SOCKETED, and can therefore be unplugged (using, of
course, proper anti-static techniques), and replaced. But IC chips sockets are virtually unknown
in laptop/notebook/pad/cell phone construction.

Hi,my computer has stopped working and just beeps at me. mother boardis a Microstar P4m266-8235. Please Help......Thank You

Hi there,

This problem could be due to carious problems.

1) Your motherboard is faulty.
2) Your Processor is faulty.
3) Your RAM chip/s are faulty.

Firstly, you will need to unplug your computer and open it up. Then you need to locate the RAM which looks like this:


Remove one piece of RAM (assuming you have more than one piece) and try to start the computer again, then if it doesn't work, remove the other chip and reinsert the chip that was first removed and try to power up again.

If it works, then one of the RAM chips were faulty and you will need to replace them.

If the computer still does not work, then either your Motherboard or Processor are faulty.

You should then buy a new motherboard which isn't too expensive (be sure to buy a motherboard that will fit in your computer and will also be able to handle your processor.). Place the motherboard with the RAM in to the computer case after removing the old motherboard. Then carefully remove the processor from the old one and put it in to the new one.

Be sure to re-insert any cables that you have unplugged from the old motherboard in to the new one. Then try and power up once the machine has safely been closed again.

If the computer works, the motherboard was faulty. If it still does not work, then your processor is faulty and you will need to buy a new processor and install it.

Alternatively, you can take the computer to a repairman who will test the various components which will save you the hassle of doing all of that work and it will also save you the cost of having to buy new RAM and a new motherboard if in fact it is actually your processor that is faulty.

Thank you for using FixYa! Have a great day and please remember to rate this solution.

ONN N15235 motherboard, which is a 775 socket. I am currently running a Pentium E2160 on its but its pretty slow so I bought an E5400 to replace it. When I changed the CPU over and started up my computer...

The LGA 775 processor socket doesn't matter, calderwooddu.

It's up to the motherboard chipset, and the BIOS program, and version, of what that Foxconn N15235 will support. I would go back to the Pentium Dual Core E2160, use CPU-Z from, (Free), and see what the motherboard chipset is, first.

(Motherboard chipset: The Northbridge, and Southbridge chips. Chip is slang for I.C. Integrated Circuit)

The Northbridge chip is what determines what Processors are supported.



Since the E2160 is built upon the 65nm technology, and the E5400 is built upon the 45nm technology, the Northbridge chip of the Foxconn N15235 may not support the E5400.

With the technology change are also Instruction Set changes. Plus other parameter changes. The BIOS program, and version on the Foxconn N15235 may not support these, either. Sorry to be a bummer.

Not a solution per se, Yet.

Need to know what computer this Foxconn mobo is out of. (MOtherBOard)
OR, if you get the computer operational again, let's use CPU-Z to see what the motherboard chipset is.
Need help in downloading, and/or installing CPU-Z, post in a Comment.

It looks as though my resources were incorrect, as far as the two motherboards having the same processor socket.
(MSI RS480M uses a Socket 754)

What does concern me, is if the motherboard chipset used is the same. This was the stated information.

The motherboard chipset consists of the Northbridge chip, and the Southbridge chip.

Chip, and Chipset are slang terms for IC. Integrated Circuit.

Viewing this motherboard diagram may help explain how the motherboard chipset comes into play,

[You can also type, one at a time, Northbridge (computing), Southbridge (computing), Comparison of AMD chipsets, in the Wikipedia search bar, to gain more knowledge]

The Northbridge chip determines what Processors can be used.
It also controls high speed graphics technology.
AGP and PCI Express being high speed graphics, not PCI.

Determines what Ram Memory is used, and what Southbridge chip is compatible with it.

Let's go back to basics, and see what Northbridge chip is on your motherboard.
Two ways.
One, it looks as though you may be using a tiny program such as CPU-Z, or Belarc Advisor.

If not, I would advise downloading the free, tiny program CPU-Z from
Can you install the old processor, (AMD Athlon 2.25GHz), and get your computer to work, or are you using it now?

After you have CPU-Z running, left-click on the Mainboard tab, and tell me what it states for Chipset. Also tell me what it states for Southbridge.

Second way.
Physically look at the Northbridge, and Southbridge chip. IF, they are not covered with a heatsink.

The Northbridge chip is usually a large chip, and is located close to the processor socket.
Most configurations are like this; Processor socket at the top of the motherboard, ram memory slots to the right, Northbridge chip below the processor socket.

Motherboard designers put the Southbridge chip all over the place. There is no usual spot.

It is my belief at the moment, that your Northbridge chip will not support dual core processors, such as an AMD Athlon 64 X2 4400+
Only Single core processors.
Once I know what Northbridge chip you have, we can determine what your CPU support is.

Hi yes thats correct you can have only 512mb RAM. This is due to your motherboard limitations or bios limitations. The only way is to change the motherboard this will allow you to also have latest usb 2 support. Just buy a motherboardboard thats compatible with your processor and existing memory.

You given me computer chip

A computer chip is a small electronic circuit, also known as an integrated circuit, which is one of the basic components of most kinds of electronic devices, especially computers. Computer chips are small and are made of semiconductors that is usually composed of silicon, on which several tiny components including transistors are embedded and used to transmit electronic data signals. They became popular in the latter half of the 20th century because of their small size, low cost, high performance and ease to produce.
