Question about ASUS P4S800D-X Motherboard

AGP 8x not supported

Video card replaced, AGP slot, from ATI Radeon 9600 Pro to VisionTek x1650pro. Power on returns 1 long and 2 short beeps. Video card error. Returned original card to AGP Slot, power on returns 1 long and 2 short beeps. Removed ATI Radeon 9600 and added old PCI video card, again, 1 long and 2 short beeps.
ASUS P4S800D-X manual states "Install only +1.5V AGP cards" (Page 1-11 of user manual). I believe the X1650 pro is AGP 8X (.8v) bus configuration.
Is this motherboard now toast?

Re: AGP 8x not supported

I have removed the motherboard from the case, disconnected everything except the power, the speaker, and the power buttons. All the pci cards and memory are out. The hard drives are also disconnected. I also put the memory stick back in and still get the same result. Very frustrating, but I appreciate your continued thoughts.

Re: AGP 8x not supported

Just a thought, but have you tried going into the bios setup and setting bios to system defaults or safe setting, saving and rebooting?

Can I use a AGP 8X ATI Radeon 9550 256MB 128bit Video Card in my pc?

No. The mainboard you are listing is not capable of AGP cards. AGP cards have gone the way of the dinosaur. Modern mainboards do not have AGP-compatible slots anymore, only PCIE 1x, 8x, and 16x slots.

Hello and Welcome to FixYa Alex.
No, the battery isn't the problem as you stated that without the Card your PC runs smooth, what i can guess is that the Graphic card is gone, and to confirm this you need to cross-check it on some other PC that can support it. If on that PC the problem is same then its clear that the Graphic Card is gone. And I guess you know that if a Graphic card is of 8x Video output interface, and the Board interface is of 4x, then the Card will run under the compatibility of 4x. A 8x Graphic Card is actually 4x/8x Graphic Card.
I hope you have a clear picture now, and yes I know you will be wondering that how come the graphic card can burn, then fellow never ever trust electronics, they are arbitrary.
If you have any questions do ask, I'm here to help.
If you think I was of help, your token of appreciation in the form of rating will be esteemed.
Concerned, Nooh

Graphics cards

Hi noxiney, you're MSI motherboard does have 1 opened AGP 8x4x slot. You can install & run the ATI Radeon X1650 PRO AGP. You can not run PCI-Express because there are no PCI-E slots on the board. There are PCI (White in color) on the board but the AGP slot is much faster than the PCI (White in color slots). The manual states the AGP card can only support 1.5volt video cards & not 3.3volt AGP cards. (Keep this in mind when looking for an AGP card).
Below is a link to a bunch of AGP 8x4x video cards. One or two include DDR2 memory. Carefull where you buy. Check the warranty. (Longer is better). The first one on the list would be compatible. Its not DDR2 but it does have 512MB of memory.

This card is 1.5v compatable.
& this is compatable.
Just remember, if the card can run both 8x & 4x it should support the 1.5volt needed to function on the MB.

Graphics card support to motherboard D845GBV

AGP 2.0 and 3.0 4x and 8x feed with the 1.5v spec. AGP 1.0 1x and 2x was fed at 3.3v. In short, you should be fine.

Intel P$ 1.8 mhz on a D845HV/D845WN board

Before removing your current card swap video outputs on the PC. If currently connected to the VGA output switch to the HDMI connector AT the video card. Use the HDMI to VGA adapter that came with the video card. Check & see if the display loads Pc starts. Taking the information directly from your motherboard manual pg. 25, your AGP video can only run at, AGP supporting 1.5 V 4X AGP cards. The 9600pro runs at 8x & it is not backwards compatible. (able to run at either 8x or 4x). You could run the Sappire ATI Radeon 256MB 9550 DDR AGP 4x/8x 1.5volt card.
Here is one site:
When you do get the video card be sure to set your bios AGP to the correct size as listed in your manual pg. 109 subsection 4.4.7
I hope this helped.

ATI Radeon Saphire 9600Pro AGP Graphics Card

It appears that the mobo is AGP 8x, and this video card also appears to be AGP 8x - so you should be able to use it just fine.

All AGP based cards are backwards compatible, so an 8x card should operate at 4x 2x and 1x

however what is important is the voltage of your slot, you can tell by looking at the slot itself,  the AGP slot may have a partition either 1/3 or 2/3rds down the slot, or may have no partition at all,

this slot partition is to prevent you from inserting a card of the wrong voltage.

If there is no partition in the AGP slot then the slot has a switchable voltage, and will automatically switch to the appropriate voltage, (on request from the graphics card AUTOMATIC)


so all you need to check is that the graphics card you buy has slots on the AGP interface that accomodate those on your board


according to the manual

This board has a 4x AGP slot
