Question about ASUS VIA 694XDP Dual Processor Chipset CUV4X-D Motherboard

1 Answer

Processor speed discrepancy

Greetings. I am having an itermittent issue during power-up, which is becoming more frequent. After the memory test of the POST, my motherboard stops after the following lines:

Award Plug And Play BIOS Extension V1.0A
Initialize Plug And Play Cards...

The system freezes here and requires a hard reboot. During the next POST, the CPU speeds listed have dropped from the original 866 Mhz to 433 Mhz. The system automatically initiates the Setup function, has the 866 Mhz listed as the CPU speed and indicates in the description section to the right that there was a discrepancy in the CPU speed during boot-up. I save the 866 Mhz CPU speed in the BIOS, reboot and the process starts all over again. I am thinking that one of the processors is sick, but I am not sure. I originally thought that it may be heat-related so I power the unit off and allowed it to cool for 24 hrs with no change in the status. I am currently running BIOS Rev 1016 on my motherboard. Any insight would be greatly appreciated.

    Thanx for the feedback. I did a physical check and did not see any capacitors that appeared "mis-shapen" in any way. Nor did I notice any evidence of a "leak" trail around any of the caps, as I would have expected in this condition. I qualify this by saying that I only checked the top surface, as I have not removed the motherboard from the case. I will continue to investigate more thoroughly. In the mean time, if you think of anything else I would love to hear more possibilities.

    Best Regards,

    Greetings again. I performed a more intensive inspection of the motherboard and did not see any indication of a capacitor leak. I decided to try pulling the PCI boards individually to see if one of them might be pulling down the PCI bus. Once I pulled the D-Link DFB-A5 USB/FireWire card, the system booted with no errors. Just as a verification, I re-installed the D-Link card to see if it would fail. Surprisingly, the whole system booted with no problems. I am still suspicious of the D-Link card, but I will have to do some more experimenting with it. Thank you for all your input.

Hey, I think you have bad capacitors. Check for buldges on the capacitors.They might of overheated beside the motherboard.You should fix it right now while you still have a chance.

    Check the bottom side, some capacitors buldge from the bottom.
    Did you try clearning the CMOS and taking out the battery?

    You might of not pushed down the card well enough. Thats sometimes causes your comptuer to not boot at all or even fry the card. Luckly your comptuer isn't blown.

1 - Upgrade Hardware

You don't describe your video card and processor specs however, there are some basic parameters
- If you have an onboard video card you can't upgrade just the video card, because it is an integrated unit, but you can update all the drivers
- In my opinion, onboard video cards and chipsets(almost all of them) have low performance for rendering purposes
- In my experience, just a better video card doesn't solve the issue--> you'll need a good "render set"--> good processor (2.6 GHz or up)+ plenty of memory (4 Gb or up) + a good videocard (512 Mb or up).

2 - Punch files

- If you are working with a heavy file, including lots of furniture, topo, etc, you should upgrade the hardware elements, but the issue is more related with the file
- If you have a slow performance with any Punch file (with just a wall, for example), then yes, a hardware upgrade is in order.
But even this, will depend of the computer / processor you have. All the elements work together as I stated above

3 - Tips

- Click on the pencil/plan icon (depending of your versions) at the top of the LiveView window (Render and Navigation Options). Clicking on the different icons you can disable temporarily the lights or 3D objects, or topo etc. This will speed the rendering during the working process

- Use View--> Render Clear view--> use this during the elaboration time

- Try to apply the 3d objects (cabinets, furniture, etc) and topography at last

- You can turn off the "Undo" feature--> Edit--> Undo preferences. This will speed your work. Just remember to save frequently (because this step deactivates the autosave for backup feature)

- To get a good Punch performance, close other programs, including the e-mail. Perhaps, other programs are using resources otherwise required in Punch.
Also I'd suggest that you try Pat's Training e-book for more resources

Computer doesnt boot, just shows, a black screen, and bipes 1 long and 2 short and sometimes 1 long and 3 short, i have tested the memorie ram and the vga cards, both are working either thinking...

This is usually a video card or RAM issue.
Make sure you got the right RAM (ie - correct speed and size [not too large/over specs]) and re-seat the video card.
Also try resetting the CMOS. As I recall, there is a jumper near the battery to do this.
With power off, move the jumper to the other set of pins, then back again after about 10 seconds, then re-power the board.

Try using only one memory stick. 1 long 2 short is a memory issue. Clean the memory contacts and reinsert the RAM.

Clean and reinsert the video card. 1 long and 3 short is a video issue. Try a different video card if you have one.

After replacing the bulged capacitors(MSI-7507) the computer doesnot bootup?Is there any other problem in the board?

Sometimes Electrolytic Capacitors, do not show visual signs of failure. The Electrolytic Paste didn't develop gas inside, it just dried up. (No bulging case, no rubber seal blown out, no paste oozing out)

The 'Caps' located around the processor, are Voltage Regulators for the processor. These 'Caps' are critical.
Processors must have 'clean', steady, supply. Their tolerance range is very small.

IF even One of these 'Caps' are bad, the processor will not start up, or keep running.
(BIOS senses the in-discrepancy, and will not turn the processor on, or will quickly turn it off)

The replacement capacitors must have the same Microfarads, and voltage.

Not doubting your soldering/electronic skills for one minute but,

1.If you have a cold solder joint, or burnt the trace on the motherboard

2.Did not follow anti-static guidelines,

3.Did not remove all hardware components from the motherboard before soldering,
(i.e, Processor, Ram Memory, and so forth)

4.Accidentally forgot to attach the 4-pin ATX power cable, from PSU to Motherboard

5.Do not have all Ram memory Modules fully seated

6.Do not have the 24-pin ATX Main power cable plugged in all the way.

7.Harddrive/s is/are, do not have the interface cable plugged in, or not fully seated.

The computer will not boot up either. Sometimes in our haste we become too zealous, and accidentally overlook some of the simple things.

As for any inherent issues dealing with this MSI motherboard, none to my knowledge

This can be on your operating system or either the fan of the processor is bad. You just need to check both of that out.

Machine shows a service code of sc 928

The SC - 928 is a Memory error problem.
The machine detects a discrepancy in
the write/read data during its write/read
test (done at power off/on and at
recovery from low power or night/off
mode). To try to reset this code -- Turn the MAIN power switch off, wait about 30 secs. then turn switch back On.

Possible causes:
• Memory defective
• BICU defective
• Poor connection between BICU and
The cheapest repair would be to replace the memory. It is rare the the connections came apart unless some one was in the back of the machine for some reason.

Restarting PC

your motherboard may be experiencing compatibility issues with that memory youve jst installed. it will work for some time but when it starts to become unstable, it will restart, you have yo adjust the memory timings for that memory in BIOS.

Ram Memory

your motherboard my only recognise two of the same size or make of ram. try the 1024mb in on it's own and see if the bios allows the system to boot and recognise it. see what windows recognises, go to my computer, right click, properties and in the main window it will tell you processor speed and look to see how much ram is showing
