I have not been able to add any AGP card to my PC.
My PC is a cube PC so I have been trying to install a "low end" AGP video card without a separate power connector. My only really requires are DirectX 9.x support and a minimum of 128MB (and no power connector)

The card I am currently trying to install is a Gigabyte ATI Radeon 9600Pro with 256MB.

I have also tried a ATI Radeon 9550 with 256MB and a Nvidia card

I have done all of the usual things, such as disabling onboard graphics, removing old video drivers, verified latest chipset drivers are installed, I reviewed the graphic adapter and don't see any conflicts etc.

I wonder if any of the cards I am trying to install will work with my AGP slot.
The manual for this Gigabyte card states "AGP 3.0 Slot or greater is required"
Unfortunately, this requirement wasn't on the Gigabyte or NewEgg web sites or the back of the box. Only in the install manual.

My Motherboard manual states "AGP 1.5v Card is required".

I got great AGP information from I used some of the tools suggested there such as Sandra Lite and other tools to try to determine what version my AGP Slot is. These tools don't seem to clearly state what

My PC is a Small Form Factor PC with 220W Power Supply.
It has integrated Intel Extreme Graphics
gBox P4 Blue CF-986L
Motherboard is a CFI-968L with last bios released (1.04)
Pentium 4 3.06Ghz
80G HD
Chipset is Intel 845GE
Intel Extreme Graphics
Windows XP Home

This is a awesome PC and I really would like to extend the life of it my adding any AGP card that supports DirectX 9.x

CONNECT 3D RADEON 9550 256MB display problem

That graphics card i'm afraid is not good for todays games, same thing goes for your pentium 4. A driver update may fix your problem but that card and cpu need changing, probably a new motherboard would be needed also to fit a pci express graphics card along with a core 2 duo processor.

Powercolor Radeon 9550 R96 256mb Card - Lights on, noone at home!

Depends on the video card ,it might require more power ,200w is fine for onboard but add other components and the system needs more power.
Disconnect the harddrive or CD ROM drive and see if the system will start.
If it starts then you will need more power 300-400w at least but shuttle power supplies can be expensive to get.

Ati radeon 9550 agp with pinnacle pctv hd problem please help

Try to put it on another pci slot. if you are using the one right under the agp, then that is your culprit.  the agp and the top pci slot share video resources.  just put it on another pci slot, if you have to swap another non-video related card to the one just beneath the agp slot.  Hope this helps.

Cant install powercolor 9600 pro on ECS 845gv-m3 mobo


Appreciate the direct "Ask Me".

Background info, a Powercooler 9600 PRO EZ was most probably manufactured by C.P.Technology in Taiwan. I am sorry to say that quality wise, this company is rather low and to my understanding, a lot of their products has to be returned/replaced even new. On the other hand, the old Nvidia MX4000 might have been manufactured by Palit, also in Taiwan but has a better quality control as of the time of production. The MX4000 though only uses 128Mb of memory but runs them at 275/400 (DDR) MHz clock speed compared to the 9600 PRO 200 (400) MHz. The slow memory onto the PowerColor RADEON 9600 PRO EZ 256MB had a really bad effect on its performance.

To your concern, the ECS 845GV-M3 (V1.0) uses AGP Express but should not cause a problem to either the 256 or 128. since it is working with the 128, then it would be safe to say that the 256 is defective. if the 256 will test OK in another motherboard, then it would be a compatibility issue, try setting the CMOS/BIOS to default and see if it will work.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

It sounds like the refrsh rate set in Windows is too high for your monitor, try going into safe mode and setting the refresh rate to 60Hz.

Grapics card


Most current AGP video cards are now 8X and they will still work with your motherboard but will just be limited to 4X. Trying to find a 4X might be time consuming whereas using an 8X downgraded to 4x would be comparatively easier and faster.

Additionally most Video cards will work under XP with the appropriate drivers but Vista has a limited list of compatible Video cards.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
