Problem continues Dear, Thank you for caring. I checked the things you suggested: 1- I can't enable AGP 3.0 mode, I don't know why 2- Aperture memory is equal to my VGA memory :256M 3-VAGP is 1.60 V 4- Init first display is AGP but it still doesn't show 8x !! :( by the way I don't know why I can't have my exact CPU rating 2200 as I described before!

    Again Thanks for having time for me,

    well... the things you asked to know,

    1- I can't find NVIDIA information so maybe you can advise where to go

    2-In AGP tp P2P bridge control, driving control is set to auto, its supposed to accept a 4 digit HEX code when its manual, but when tried, I could just enter 2 digits!

    3-In CPU & PCI Bus Control, Vlikn 8x is enabled

    4-I can't change the VAGP value if its suposed to changable in PS health status. I mean I just checked that place.

    5-The VGA manufacturer,in windows I found "Nvidia Technologies Inc." But I couldn't find any brtand on the VGA itself. Seems its not one of good ones

    6-Power is rated to supply 400 Watts

    ** After I updates BIOS, I found a new setting in power bios...

    its: Async AGP CLK. Do you think its helpful?

  • arman1357 Mar 29, 2008

    Yes, the ATX 12V 4-pin connector is connected.

    AGP CLK was disabled by default, I changed it bot nothing happened as far as I understood.

    I don't have such an icon for NVIDIA. I've installed the VGA driver but this icon you are telling me dosn't exist.

    I would like you to download and install PC wizard, so I can take a look if agp 3.0 is enabled:

    Might also give some insite to why CPU is at a lower setting.

    download here:

    run it and go to file-save as, click ok and then save the text file to your desktop. Then copy the text out of that file to this thread

  • Dave MacPhee

    How you downloaded the latest forceware release from NVDIA?

    That should give you the icon I'm refering to...

  • Dave MacPhee
    Dave MacPhee May 11, 2010

    Not too sure what happened.. But i posted before this one, and then it just dissapeared.. I hope I can remember everything I asked..

    First and foremost, on your motherboard, right beside the main power connection, there should be a ATX 12V 4-pin connector, does the power supply connect to this?

    No, the AGP CLK will not help here, don't change it.. Although, what is it currently set to?

    For your nvidia information, when you in windows, at the bottom right hand corner, there should be an icon that's green with the nvidia logo, click on it, then click on Nvidia control panel.. in there, click on help at the top, and then system information.. What's listed there?

    Let's go with that for now.

  • Dave MacPhee
    Dave MacPhee May 11, 2010

    Check the graphics card itself and see if there is a label with the brand name or at least a model number listed.

    No, AGP CLK setting should not be changed, and will not help in this case.

    Another question.. On the motherboard iteself, there is a 4-pin ATX 12v connector, right beside the main power connection.. Does your power supply connect to the 4-pin one as well?

  • Dave MacPhee

    After much searching, It seems that the 4x vs 8x will not really make much of a difference. So, now it comes down to what is really going on with your games/programs and the card..

    Before I recommend returning the mobo (as I don't think this is the best mobo out there).. Let's check some other options in the bios and system..

    In Windows:

    First, go into your Nvida control panel, and under help, click system information.. Check what is says for card speeds there.

    In the BIOS:

    Under the AGP to P2P bridge control, is your Driving Control set to auto?

    Also, under CPU & PCI Bus Control, is the Vlink 8x enabled? (don't change that setting yet, just curious).

    Back in the VAGP area, can you change the voltage (don't change it if you can)?

    Lets check these first, and after we fix your graphics issue, we'll figure out what's going on with your CPU speed.

  • Dave MacPhee
    Dave MacPhee May 11, 2010

    Who is the manufacturer of the graphics card? (Abit, EVGA, etc..)?

  • Dave MacPhee
    Dave MacPhee May 11, 2010

    How many watts is your power supply rated for? Could be not enough power getting to the components.

    I will also mull over some other options and get back to you.

Nikon D5100 wont flash

Here is a list of things to check:
1. Go into the camera's menus and make sure that the flash is enabled.
2. Check in the menus that the flash is not set in the command mode.
3. You didn't say if your camera was in the auto mode, aperture or shutter priority, etc. If the camera is in shutter priority or manual mode, make sure that the shutter speed is below 1/250th of a second.
4. Make sure that the ISO speed isn't set so high that the camera thinks that flash is not needed.

3 log beeps on power on

Gigabyte doesn't list 3 long beeps as an error code, so I'm not sure if you're actually getting 3 short beeps or maybe 1 long and 2 short or... But, for reference, Gigabyte's error code list is as follows (depending on whether you have an AWARD BIOS or an AMI):

1 short beep: System normal
2 short beep: CMOS Error
1 long beep and 1 short beep: Memory error
1 long beep and 2 short beep: Graphic card error
1 long beep and 3 short beep: AGP error
1 long beep and 9 short beep: Memory Error
Continuous long beep: Memory not correctly installed
Continuous short beep: Power supply unit failed

1 short beep: Memory Error
2 short beep: Memory parity check error.
3 short beep: Basic memory 64K address check error
4 short beep: Real Time Clock malfunction .
5 short beep: CPU error
6 short beep: Keyboard error
7 short beep: CPU interruption error
8 short beep: Graphic card error
9 short beep: Memory error
10 short beep: CMOS error
11 short beep: CPU cache memory malfunction

It might not be a lot of help, but it's somewhere to start... and at least this way you'll know what to be listening for.

Have gforce4 ti video card NO PICTURE of any kind screen says no signal detected

The GeForce4 Ti has two rear ports. 1 HDMI and 1 VGA. Try plugging into each. Video signal should be sending out of one of the ports. If neither port is sending out signal than you'll need to trick the bios.
Suggest you remove the Gforce4 Ti AGP card from the MB so you can regain video display and change the settings within the bios. Once you have display, enter the bios menu. Do you have your manual? Enter bios menu by pressing the "Delete" key every 2 seconds until the bios menu loads. Open, Integrated Peripherals, see top of page 3-11. Set Primary Graphic's Adapter to: [AGP]. Than go to the top of page 3-10. Change the AGP Aperture Size to as low as possible or to: [Disabled] "preferred".
AGP 8x Support set to: [Enabled]. Save your settings and exit the bios. The system will restart. Press and hold the power on / off button until your system shuts off. Install your GeForce4 Ti AGP video card. Double check your video card! Some NVIDIA cards need external power above what the AGP slot can provides. Some use a power connector like the floppy drive uses. Other look just like a hard disk drive power connector: 4-pin Molex. If none is found don’t worry about it.

Radeon 9550 + AGP issues on MSI KT4V

First of all, why do you bother to change all these spec? Secondly, since your screen flicked, I would suggest you just leave them like that. Your PC is just as old as mine, don't mess around with it too much.

You better off getting an AGP card as your onboard graphics cannot be altered from what i can see and in any case will not be good enough to play most games as the 3d and shader won't is needed
