What characteristics of a system board determine the amount of memory?

The amount / pattern of beeps you are getting generally determines the fault. My first guess would be memory, reseat your memory, video card and cables. If the problem persists and you have several memory modules, take them all out and insert them individually into different memory slots. and if the problem still persists reply with the amount / pattern of beeps you are hearing?

Phase 1
After power button pressed, computer will detect 5 components :
1. Power supply - OK (enough power)
2. Main-board - OK
3. Processor - OK
4. Memory - OK
5. Video Card / VGA - OK
== beep sound .. (1 time) or on the monitor, display appears BIOS ==

The characteristics of damage to power supply
1. Power supply fan does not spin

Video power supply fan not spinning

If the power supply fan is not spinning, the possible cause of damage to power supply. Solution, replace the power supply.

How to check the damage to power supply
2. Power supply is weak (resulting voltage power supply can not turn on the computer or the voltage is less)
The characteristics of damage to the processor

Normal fan without processor
Normal fan with processor


Based on experience, the possibility of damage processors is very small. To check for damage to the processor, install the processor to another computer (for comparison).


The characteristics of main-board damage
Because the new main-board, so the possibility of the main-board damage, very small. The characteristics of damage to the main-board, when the power button is pressed
1. Power supply fan not spinning
2. Processor fan is not spinning
3. Casing lamp is not lit
4. Main-board lamp does not light


The characteristics of the memory damage or dirty memory
1. The characteristics of normal memory, but installation is not correct or dirty

When the computer is turned on, the sound


Solution



Picture a
Release Memory

Picture b
Clean the memory slots with a brush

Picture c

Please let me know if this washelpful and if it solved the problem! Also if the information provided washelpful, please click on the appropriate thumbs to make us aware that theproblem has been corrected or that the information provided helped you with theproblem.. Thank you and Good Luck.

CAUSE:
The Windows 32-bit protected-mode cache driver (Vcache) determines the maximum cache size based on the amount of RAM that is present when Windows starts. Vcache then reserves enough memory addresses to permit it to access a cache of the maximum size so that it can increase the cache to that size if needed. These addresses are allocated in a range of virtual addresses from 0xC0000000 through 0xFFFFFFFF (3 to 4 gigabytes) known as the system arena.

On computers with large amounts of RAM, the maximum cache size can be large enough that Vcache consumes all of the addresses in the system arena, leaving no virtual memory addresses available for other functions such as opening an MS-DOS prompt (creating a new virtual machine).

WHAT CAN U DO?
To work around this problem, use one of the following methods:

• Use the MaxFileCache setting in the System.ini file to reduce the maximum amount of memory that Vcache uses to 512 megabytes (524,288 KB) or less. For additional information about how to use the MaxFileCache setting, click the article number below to view the article in the Microsoft Knowledge Base: 108079 (http://support.microsoft.com/kb/108079/EN-US/ ) 32-Bit File Access Maximum Cache Size
• Use the System Configuration utility to limit the amount of memory that Windows uses to 512 megabytes (MB) or less.For additional information about how to use the System Configuration utility, click the article number below to view the article in the Microsoft Knowledge Base: 181966 (http://support.microsoft.com/kb/181966/EN-US/ ) System Configuration Utility Advanced Troubleshooting Settings
• Reduce the amount of memory that is installed in your computer to 512 MB or less.

Print speed can be affected by three important factors:
Available computer RAM
Available computer hard drive space
The HP All-in-One product paper sensor
Follow the steps below the ensure the computer is operating properly.

Step one: Verifying the amount of RAM
Verify the amount of RAM installed in the computer.
Determine the amount of memory currently in use by background programs or processes.
Programs/processes will run in the background even when no applications are running. Most of these programs/processes will be indicated by an icon in the lower right corner next to the time.
Less memory available for applications will result is slower processing time and consequently, printing speed.
To determine processes running in Windows 2000/XP , do the following:
Press Ctrl , Alt , and Delete simultaneously and then release.
From the Windows Security box, select Task Manager.
Click the Processes tab to view all running processes.
Click the Performance tab to view the total and available amount of memory.
To determine processes running in Windows 98 , do the following:
Open the Device Manager .
Click the Performance tab.
The available system resources will display as a percentage.
Turn off unnecessary background processes.
This will free up system resources and increase printing speed.
To turn off processes in Windows 98/ME/XP , do the following:
Click Start , Run , and type msconfig.
From the System Configuration Utility, click the Startup tab.
Determine what processes are unnecessary and remove the checkmark those items.

Step two: Verifying the amount of hard drive space
Follow the steps below to determine the amount of hard drive space on the main drive.
Open My Computer , right-click the C drive, and then click Properties .
This will display a chart along with the total hard drive space, used space, and available space.
Verify that there is at least 2-3 GB of hard drive space available.
The computer will require at least this amount to process printing data for simple text files, more for image files. The lower the amount of available hard drive space, will greater the time to process print data.
Step three: Ensuring the paper sensor is clean and not damaged
The all-in-one product paper sensor plays an important role in determining the print speed.
Printing a self-test or demo page will ensure that the paper sensor is in proper working condition. If the page completes in less than 40 seconds, the sensor is working correctly.
Even if the sensor is working correctly, the printer driver might need to have the paper sensor turned off. To turn off the sensor, follow the steps below:
Open the Printer folder, right-click the printer and click Printing Preferences or Properties.
From the Properties box, click thePaper/Quality or Features tab.
Under the Paper Type section, open the menu and select Plain Paper instead of Automatic.
This will disable the paper sensor and increase the print speed

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251

Not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept. For instance, when you install 4GB of memory in a 32-bit Windows system (the most common version; 64-bit systems are typically used by high-end users), your system reports only 3GB or 3.5GB.
First , we can assure you, there isn't a problem with the memory. While Windows allows for 4GB of memory to be addressed, it does not equate to 4GB of physical memory. Some of the memory (regardless of how much you have installed) is reserved for use by the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc, meaning it is unavailable for use as normal main memory. Upon startup, your system calculates the amount of memory needed for these devices; if you haven't maxxed out the memory in your system, it's invisible to you, and all your physical memory (the installed RAM) is available for use. However if you've maxxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM. The maximum memory limitation varies by operating system, For instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.

Gateway's website says this motherboard will support 4GB of DDR333 or DDR400 memory. I would suggest testing each memory modules by plugging it into the board by itself, then rebooting. This way you can catch a bad DIMM that might be causing problems. If each one checks out then start adding one module at a time, rebooting after each one. If it still stops booting after you add a module, you probably have a bad system board, and only now that you are adding the extra memory are you finding that out. If that is the case, try contacting Gateway support. Maybe they would be kind enough to cover repair under warranty.

This is a problem with your memory.

During POST, the computer checks the computer's memory, determines the amount of installed memory, and then writes to and reads from the number of available bytes to ensure proper operation.
Basic Checks:

• If an insufficient memory message appears, save and close any open files and exit any open application programs not in use.
  
  
• Consider installing additional system memory.
  
  
• Run the System Memory test in the Dell Diagnostics.
  
  
• Reseat the memory modules.
  
  
• Restart the computer.

If the problem still exists after you complete the basic checks, fill out the Diagnostic Checklist as you perform the following steps.
CAUTION: Before you perform this procedure, see "Safety Information."

1. Reboot the computer.

Does the RAM count displayed correctly match the actual amount of memory installed in the computer?
Yes. The computer needed to update the memory count. The problem is resolved.
No. Go to step 2.

1. Run the System Memory test group in the Dell Diagnostics.

Did any of the diagnostics tests fail?
Yes. Contact Dell for technical assistance.
No. Go to step 3.

1. Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then open the computer cover.
   
   
2. Rotate the power supply away from the system board.
   
   
3. Replace the memory module(s).
   
   
4. Close the computer cover, reconnect the computer and peripherals to their electrical outlets, and turn them on.

Does the RAM count displayed correctly match the actual amount of memory installed in the computer?
Yes. The memory module(s) were defective. The problem is resolved.
No. Contact Dell for technical assistance.

More than likely the 2nd slot your trying to use is bad, however before you make that assumption try inserting a stick in the possible bad slot by itself and see if it will post. Let us know :-)
