  • The most popular question from the MSI crowd is "How much did you spend on your system?

It's getting much cheaper to purchase computer parts.  Look at what I paid 2 years ago compared to what I could get today.

I purchased most of my parts in San Diego at this shop:


  • Has MSI certified the K9N Diamond (MS 7226) to run Windows Vista?

No, not yet, but MSI tech support has assured me that the MSI K9N Diamond is undergoing testing as we speak and will be certified for Vista in the near future.  In the mean time check out this link to see what MSI mainboards ARE certified for Vista:  MSI Vista Ready Mainboards


  • PCI 2 SlotWhy does your mainboard have one orange PCI slot?  Is there something special about it or is it just orange?

The Orange PCI 2 slot is for a "Bus Mastering PCI Device".  Bus mastering is the capability of devices on the PCI bus (other than the system chipset, of course) to take control of the bus and perform transfers directly.


  • How do you clear CMOS on the K9N Diamond?

See my troubleshooting guide.


  • What do the lights on the D-Bracket™2 mean?

    I highly recommend you install (at least initially) the D-Brackett™2 that comes with your MSI K9N Diamond.  It integrates four LEDs and allows users to identify system problems through 16 various combinations of LED signals.  (I created the following GIFs with Paint Shop Pro).

In order for your D-Brackett™2 to work properly it has to be plugged in to the JDB1 pins.

LED Signal Description LED Signal Description
System Power On
The D-LED will hang here if the processor is damaged or not installed properly.
Initializing Video Interface
This will start detecting CPU clock, checking type of video onboard.  Then, detect and initialize the video adapter.
Early Chipset Initialization Bios Sign On
This will start showing information about logo, processor brand name, etc...
Memory Detection Test
Testing onboard memory size.  The D-LED will hang if the memory
module is damaged or not installed properly.
Testing Base and Extended Memory
Testing base memory from 240K to 640K and extended memory above 1MB using various patterns.
Decompressing BIOS image to RAM for fast booting Assign Resources to all ISA
Initializing Keyboard Controller Initializing Hard Drive Controller
This will initialize IDE drive and controller.
Testing VGA BIOS
This will start writing VGA sign-on message to the screen.
Initializing Floppy Drive Controller
This will initializing Floppy Drive and controller.
Processor Initialization
This will show information regarding the processor (like brand name, system bus, etc...)
Boot Attempt
This will set low stack and boot via INT 19h.
Testing RTC (Real Time Clock) Operating System Booting

  • Why haven't you upgraded your bios?

I updated my bios to v1.7 on 12/22/07 because I installed a new CPU (AMD Athlon 64 X2 6000+).  At the present time my system is running GREAT with no problems.  You should only upgrade your bios if you have a specific need or a problem which is bios related. 

If you need to upgrade your bios follow this procedure.


  • Are you going to try overclocking your MSI K9N Diamond?

No, I'm not interested in overclocking my CPU/mainboard.  However, MSI's built in Dual Core Cell allows the user to automatically overclock by using the built-in Dynamic Overclocking Technology (DOT).  This is located in the Bios Cell Menu under CPU Dynamic OverClocking. 

Dynamic Overclocking Technology is the automatic overclocking function, included in MSI's newly developed CoreCell™ Technology.  It is designed to detect the load balance of the CPU while running programs, and to adjust the best CPU frequency automatically.  When the mainboard detects the CPU is running programs, it will speed up the CPU automatically to make the program run smoothly and faster.  When the CPU is temporarily suspending or staying in the low load balance, it will restore the default settings instead.  Usually the Dynamic Overclocking Technology will be powered only when the user's PC needs to run huge amounts of data like 3D games or the video process, and the CPU frequency needs to be boosted up to enhance the overall performance.  Settings are:

  • Private 1st level of overclocking, increasing the frequency by 1%
  • Sergeant 2nd level of overclocking, increasing the frequency by 3%
  • Captain 3rd level of overclocking, increasing the frequency by 5%
  • Colonel 4th level of overclocking, increasing the frequency by 7%
  • General 5th level of overclocking, increasing the frequency by 10%
  • Commander 6th level of overclocking, increasing the frequency by 15% 


Even though the Dynamic OverClocking Technology is more stable than manual overclocking, basically, it is still risky.  We suggest the user to make sure that your CPU can afford to overclock regularly first.  If you find the PC appears to be unstable or reboot incidentally, it's better to disable the Dynamic OverClocking or to lower the level of overclocking options.  By the way, if you need to conduct overclocking manually, you also need to disable the Dynamic OverClocking first.

  • I'm not getting any sound from my speakers.  What can I do?

See my troubleshooting guide.


  • I'm having problems with Bios v1.3.  Can you help?

The word from the MSI Forums is that numerous people were having problems with Bios release v1.3.  At this time I do not recommend updating your bios to version 1.3.

As of April 2007 MSI has removed v1.3 for download from their website.


Follow this procedure to boot your bios update from a CD-rom:

1.  Download the BIOS Zip file from MSI; extract the Zip files.  The files you will need are the <flash utility> and the actual <bios file>.  For example, if you plan to flash your bios to version 1.1 the files are:

Flash utility:  Afud408.exe
Bios file:  A7226NMS.110

2.  Create a bootable CD using <> and follow the procedure found here:  The flash utility and bios file from Step 1 above will also be burned onto the CD.

3.  Enable your PC to boot from the CD-rom by hitting "F8" or "F11" at startup = or = configure your CD-rom to boot first in bios; your choice.  Insert the bootable CD you just created and boot your PC.  The PC will boot to the DOS prompt A:\>.  Change the DOS directory to the drive your CD is located in and type the full file names of the <flash utility> and <bios file> you extracted in Step 1 above and press ENTER. 

Example:  D:\>Afud408.exe A7226NMS.110 (and press ENTER)

Your Bios will now flash.  Follow the prompts.

4.  After the BIOS update has been completed successfully, power down your PC, remove power cord from the PSU, press the power button to drain electricity from the capacitors, touch some metal with your hands to discharge any ES which you may have, then open the case and Clear CMOS (push the red button).

5.  Replace the power cord and turn on your PC; your monitor will give you a "CMOS CHEKSUM MISMATCH/ERROR".

6.  Hit F1 to continue to rebuild the DMI Pool Data.

7.  Reboot your PC and watch for the new BIOS version number (or just look in Bios System Information)


9.  Go back into BIOS again and verify customs settings from my site.


Yes I have.  It works fine and I have not encountered any problems to date.  If I do experience problems in the future, I will post them here.

I got tired of waiting for Vista SP1 to become available on Windows Update so I downloaded it from here:

I thought there might be a chance my SB Audigy would not work after SP1 was installed but it still works fine with no changes that I can tell.  I'm running 2.1 Logitech X-230 speakers.

SP1 installed fine and everything appears to be running perfectly.


A 32-bit version of Vista (or XP) will never even use the full 4GB of RAM in your system. It's because of the memory mapped IO reservations, which control how the onboard memory on your installed devices overwrites parts of the system memory, which lowers the total memory available to Vista itself.  According to Microsoft, the 32-bit version of Vista is limited to 3.12GB of total available memory:

This goes the same for servers, which is a key reason why 64-bit computers are getting increased attention.  Memory is no longer expensive and it can help a lot so limitations like this become a real headache for many.

So you move to 64-bit.  With this comes some stiff driver requirements, but what do you get for RAM limitations with Vista 64-bit?  Actually, it depends on what edition of Vista you are running:  Home Basic is limited to 8GB, Home Premium is limited to 16GB and the other editions (Business, Enterprise and Ultimate) let you get all the way up to 128GB.
