Question about Shuttle MK40VN Motherboard

2 Answers

No video signal from onboard, agp, or pci cards

I just bought a shuttle mk40vn v1.3a with the via km400 chipset. the box calls for amd athlon xp/athlon/duron processors. it uses pc2700 ddr ram. i installed my amd athlon and 2 kingston 256mb pc2700 ddr rams sticks. i connected my western digital 80gb harddrive and the liteon cdrw drive. then connected my monitor to the onboard vga connector and the keyboard and mouse and the cable internet to it. when i turn the thing on it checks the cdrw drive and it runs the harddrive like its booting up but nothing comes on the screen. so i tried installing an agp card for video and still nothing happened. i then tried a pci card and yet nothing. i though maybe i should test with just one memory stick and nothing. then with no harddrive or cd drive and nothing. i tried changing all the jumpers around and nothing. clearing cmos does nothing. and since shuttle doesnt make this board anymore i cant return it. so here is my question. i heard somewhere on irc that sometimes even though the manufacturer says that a board supports a cpu it doesnt always. the cpu worked on another board that i messed up with a slip of a screwdriver while trying to remove it to put this new board in. so i know it works. the psu works cause everything is coming there anyway to fix it. please if you can help me cause its getting really hard to get my school work done using everyone elses computers...

Check the jumpers on the board. I just put a 2400mhz on mine and changed the jumpers and it read it right finally

Re: no video signal from onboard, agp, or pci cards

Prophitinc, I'll try to help. First off a real basic question, the specs I have say this board has a built in video adaptor. Did you make sure that the BIOS was configured use the plug in card? Some BIOS's can do this on their own but I would check anyway. -The first thing I would do is to check each screw, card, connector and component you installed to make sure nothings being shorted out or is improperly connected. Common occurrences are screws touching capacitor or other component leads. -Check the power connectors to make sure everything is connected correctly and that all the contacts are still mounted in the plastic connector correctly. -Check the output on your power supply and verify it?s rated for your motherboard. -Make sure the motherboard is correctly grounded to the chassis per your instructions. Typically the mounting screws touch a grounding plane on the motherboard and in turn ground that to the chassis. If your using plastic mounting studs that might be a problem. Make this as basic a machine as possible: remove any add in cards, use the built-in video (make sure you enable it via the BIOS), unplug mice, remove all USB components, reduce the size of your memory (RAM) and if you have multiple hard drives remove all except your boot drive. If you have on try a basic PS2 style keyboard you know works. Restart, does anything change? If this doesn't result in some changes then some more information is necessary. In light of your situation I?ll be checking back for another couple of hours: -Are all of these parts from the old machine, IE do we know they all work? -Any beeping or noise coming from the machine during booting except fans? -You say it behaves as if it were booting; what about hard drive activity? How long is it running? -What exactly were the conditions in which the last board was damaged? Was it plugged in and powered up?

K7SV266AD Can I use 266Mhz athalon processor with this board, book says 100/133 FSB. If so what processors? Thanks

The Syntax K7SV266AD motherboard uses a VIA motherboard chipset.

It uses a VIA KT266A for the Northbridge, and a VIA VT8235 for the Southbridge.

About the motherboard chipset;

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

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

High-speed graphics is AGP or PCI-Express

A graphics card inserted into a PCI slot is Not high-speed graphics.
Neither is Integrated Graphics.

(Integrated Graphics is also referred to as OnBoard graphics.
ON the motherBOARD. The graphics chipset is soldered directly to the motherboard, and not to a graphics adapter card. {Graphics card}

The graphics chipset is a GPU.
Graphics Processing Unit,

The Southbridge chip handles the slower capabilities of the computer.
It handles the IDE, and SATA capabilities of the computer.
It also handles the USB ports, Ethernet, and Audio, plus anything connected to a PCI slot, and Integrated Graphics, to list a few examples.

Motherboard Diagram,

[For further information you may wish to search on Wikipedia,
A) Northbridge (computing)
B) Southbridge (computing)
C) Bus
D) PCI Local Bus
E) AGP (Accelerated Graphics Port)
F) PCI Express
G) Front Side Bus ]

Looking at the motherboard with the Processor to the top, and Ram Memory to the right, the VIA KT266A northbridge chip is below the Processor.
The aluminum finned Heatsink covers it.

The VIA VT8235 southbridge chip is down towards the lower right corner.

Looking at the specs for the VIA KT266A chip we can see,

1) It supports either DDR Sdram ram memory at 200MegaHertz, or 266MHz.
PC-1600 or PC-2100, respectively.
(DDR Sdram is clocked twice. Therefore the 133MHz Front Side Bus {FSB} support will handle 266MHz ram memory)

2) The Maximum ram memory it will support is 4GB. If you have the motherboard manual, you will know what the maximum amount of Ram Memory is, that the motherboard will support.

3) Will support Processors with either a 100MHz, or 133MHz FSB. (Front Side Bus)
AMD processors are 'Double-pumped'.
The VIA VT266A chip will handle AMD processors with up to a 266MHz FSB.

It will handle AMD Athlon, or AthlonXP, or Duron processors, with a maximum FSB of 266MHz.

The best processor will be an AMD AthlonXP with a 266MHz FSB, that fits in a Socket A (Socket 462) processor socket.

Watch the Voltage used. Look up the AMD processor you have installed now, and see what voltage range it uses. The new processor must use voltage in this range also.

I would like advice on upgrading my Graphics card

Unfortunatly your still running low end CPU power and low end agp graphics. Your going to pay 150-200 just for a fair PCIe/AGP HD/3D VC. If $200 doesnt hurt (and this is the lowest price best option), then might I suggest Mobo/CPU/RAM for around $200 that would do the trick and allow for future upgrades. You might also need a power supply. I just built one less than 3 weeks ago for a friend and it fairs against my own gaming comp.
MY PC...
AMD ATHLON 64 X2 DCP 6000+ 3.01GHz

GeForce4 MX 420 Video Card

First question: Are you sure you have a PCI card?
there are several points here:
Make sure you have the monitor connected to the correct output on your computer. (In this case to the output of the graphics card, not to your onboard output)
If you have a PCI card set bios to PCI
Setting it to AGP means the computer is looking for a graphics card in you AGP-slot on you motherboard.

I cannot help thinking, that you actually have a AGP card in a AGP slot and that you computer is not working on onboard, but on AGP. But you can check which graphics device is used, in display properties (right-click Desktop, Properties, Settings)

Please post some feedback

Video card

actually your computer is working on the onboard video adapter.

1. connect first the monitor to the onboard video card.( do not remove the connected geforce video card.)
2. switch on the computer and press "F2" on new model computer, "Delete" on old model computer.
so that you can enter to bios setup.
3. if bios setup is open; try to find the "AGP bridge configuration"
(some other bios AGP B C is in chipset) by arrow up,down,side left and right) enter.
4. Find " primary graphics adapter"
5. In there, select : If Video card is "pci" connected ; select "pci"
If Video card is "AGP" connected ; select "AGP"
6. press F10 to save and exit the setup.
7. after saving the configuration, disconnect power cord and transfer the monitor to the video card (Gforce). and then connect the ac power cord and then start. or switch on the computer.

Note: be sure to install the drivers of your GFORCE for optimum performance of the card.

hope this help.

it is a matter of socket..your processor is normal AMD XP 2500 ++ which fit in the socket of the board..that socket is quite'old'///It is called socket this socket you cant put a new athlon 64 will never fit..the 64 athlon has slots like 754 or 939.....and now 940...well...for the processor you need to change the board...and for the video should change it too..the pcie is a special slot...the pcie express video card will never fit in the agp slot:)
oh...the performance is much really should do this upgrade..
here is  areview of your chipset
