You need the motherboard user guide for clock settings etc but first ensure that the socket set (number and distribution of pins) on the new CPU matches that on your board. You should find a user guide on the manufacturers website, follow links for support and downloads.

Here's the page for your CPU on the intel website:-

According to this, *********** board needs to have a PLGA775 CPU socket.

Assuming so, its a case of setting the clock jumpers to match the processor speed.

I have a mainboard of model D845GVAD2------------------------AAC18931-104. It has already intall the Intel celeron processor of 1.8GHz. Now I want to upgrade my processor. So what high frequency processor...

The Intel® Desktop Board D845GVAD2 supports a single Pentium® 4 processor with a system bus frequency of 400 MHz or 533 MHz, or a single Celeron® processor with a system bus frequency of 400 MHz.

So you can install upto 3.06 GHz 533 MHz(cache memory) processor and also update the ram 2 GB 400 mhz.
Dont install Prescott processor.
Hope it will help you.

Motherboard p3v4x : during bootup i get a system

This error is usually caused by an incorrect setting of either bus speed or multiplier (or sometimes processor chip operating voltage). These could be set either by software ie in BIOS or by changing tiny switches mounted on the motherboard.
Have you consulted your motherboard manual?
Try here:
or try the ASUS website and look under support or the discussion forums.
This will help:

These freq and voltage settings are set under BIOS which is usually accessed by hitting the DELETE key on your keyboard after turning on your computer.
Sometimes a quick fix is to enter BIOS as per the above instruction and selecting LOAD BIOS DEFAULTS or something similar to that and then save and exit BIOS and allow the computer to reboot.. That may get you to the point of booting up without the improper freq comb error.
If you have no luck playing with the above info, shut down your computer and remove the left hand side cover on your computer box or tower, so you can access the inner workings of your computer.
Remove the cooling fan from your processor chip. It will be a large square or circular (black or silver colour).
Take a look at your processor chip. Note the part number printed on the chip, which is only visible after you remove the cooling fan. For example it may say for example SL52P or something else. It may also be an AMD chip.
Search the internet for its specifications ie search for SL52P.
For example, if it was a Pentium 3 chip running at 800 Mhz go to google and search for specs of P3 800 Mhz processor with the part number SL52P.
Google returns the following info (based on the example above) of:
ie its a chip that runs at 800Mhz speed with the memory running at 133 Mhz (800 mhz processor speed obtained by having the multiplier set to 6 but actually means the memory is running at 133 MHZ but the processor running at 6 times the speed of the memory bus ie 133x6=800 MHZ (one of the settings you need to get right in your BIOS settings)
So if you had this chip, in BIOS you would select 133 bus speed, with the multiplier of 6 usually locked down on the processor physical internal wiring.
If your BIOS doesnt allow you to play with the processor and memory bus settings (commonly done to make the processor overclock to a faster speed) the other option is that you have the DIP switches on your motherboard set to the wrong settings. Again, refer to to your motherboard manual. The DIP switches are tiny plastic switch blocks on the motherboard with a row of (usually) white sliding switches.

2600+ with ASUS MB A7V266-E/AA

Here is the CPU Support list from Asus Support, for the Asus A7V266-E,

Scroll down the list. 34th one down, that is listed.

1.Did you get the Athlon XP 2600+ that has a 266MegaHertz, (MHz), Front Side Bus? (FSB)
The AXDA2600DKV3C?

There is an Athlon XP 2600+ that has a 266MHz FSB, and one that has an FSB of 333MHz. <-This one Won't work.
Model number ->AXDA2600DKV3D will Not work.
Both are Thoroughbred A/B Core models.

The AXDA2600DKV3C has a 12.5x multiplier.
Your 1900+ has a 12x multiplier. (AXDA1900DUT3C) They both have an FSB of 133MHz. (Shown as 266MHz because AMD processors are 'Double-Pumped')

A.The AXDC2600DKV3C will not work. It has a 16x multiplier. (Thorton Core)
B.The AXDC2600DKV3D will not work. It has a 333MHz FSB. (Thorton Core)
C.The AXDA2600DKV4C will not work. It has a 15x mulitplier. (Barton Core)
D.The AXDA2600DKV4D will not work. It has a 333MHz FSB. (Barton Core)
E.The AXDA2600DKV4E will not work. It has a 400MHz FSB. (Barton Core)

2.Are the jumper blocks -> CPU RATIO, and SYSCLK, still set in the Jumper Free Mode?

By the factory default settings these jumper blocks, (DIP switches), should already be set to Jumper Free Mode.
The white DIP switches should be in the OFF position. (The white switches will be DOWN, towards the numbers on the jumper block CPU RATIO. They will be UP, away from the numbers, on the jumper block SYSCLK))

The CPU RATIO jumper block is right above the processor. It is a blue rectangular block.
The SYSCLK jumper block is down the motherboard, right below the AGP graphics card expansion slot. (And above the first PCI expansion slot)

If those two jumper blocks are not set to Jumper Free Mode, set the DIP switches in the jumper blocks to this setting.

Now go into BIOS Setup. In the main menu use the Right Side Arrow key on your keyboard, and highlight Advanced.
If -> CPU Speed is set to Auto, you won't have access to set your CPU parameters. If it is set to Manual, you will see them. If it's set to Manual, write down the headings, (CPU:System Frequency Multiple, System/PCI Frequency (MHz), and so on) Write down the numbers to the right of these headings. If something goes wrong, you can go back into BIOS Setup, and change them back.

1.CPU:System Frequency Multiple should be
2.System/PCI Frequency (MHz) should be
3.System/DRAM Frequency Ratio should be
4.CPU Vcore should be (1.750)
5.CPU Level 1 cache, and Level 2 cache should be (Enabled)
6.CPU Level 2 cache ECC Check should be (Disabled)
7.BIOS Update should be (Enabled)
8.PS/2 Mouse Function Control (Auto)
9.USB Legacy Support (Auto)
10.OS/2 Onboard Memory >64M (Disabled)

Leave the rest alone.

The AXDA2600DKV3C uses 1.65 volts, has a 12.5 clock multiplier, and a 266MHz FSB. (You will see 133MHz, and set all your settings to 133MHz. AMD processors are 'Double-Pumped'. Intel processors are 'Quad-Pumped')

Highest processor for intel 810 Motherboard

i cannot give you a specific list of models but in general every pentium 3 cpu with a front side bus [FSB] frequency not greater then 133 mhz should work on that chipset. i also do not know where you could find a pentium 3 cpu for sale.

No. DDR replaced the SD in RAM so SDRAM and DDR RAM are two completely different things but each ram type has its own frequency hence you get SDRAM 100(mhz) and SDRAM 133(Mhz) just like you get DDR 1 RAM at 266(mhz) and 400(mhz) and DDR 2 RAM at 533(mhz) and 800(mhz). Therefore as you can see how these things differ, but if your mboard takes SDRAM that it can take and frequency of SDRAM but you must ensure that all the frequencies of all your RAM modules in all your slots correspond otherwise you will have problems, meaning that if you decide to use 133mhz RAM then all your RAM modules that you use must be the same. Let me know how you go. thanks

4 x 1GB DDR400 installed; only 3GB recognized by MOBO

If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as: - System BIOS (including motherboard, add-on cards, etc..) - Motherboards resources - Memory mapped I/O - configuration for AGP/PCI-Ex/PCI - Other memory allocations for PCI devices Different onboard devices and different add-on cards (devices) will result of different total memory size. e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses. On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices. This limitation applies to most chipsets & Windows XP 32-bit version operating system. If you install Windows XP 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met: 1. The memory controller which supports memory swap functionality is used. The latest chipsets like Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture can support the memory swap function. 2. Windows XP Pro X64 Ed. (64-bit) or other OS which can address more than 4GB memory. You can check below URLs for reference:
