(I posted this in the videocard sticky last night, but that thread seems to get overlooked)

I just got a new evga 6600gt 128mb AGP card today, but I'm concerned that it may not be compatible with my motherboard.

According to newegg (where I purchased), the interface for this card is 4x/8x AGP (newegg specs). I added it to my 3 year old Dell with a stock board (an Intel i845PE) which has a 4x AGP slot. I also installed a new 450 watt power supply. There is a very noticeable improvement over the previous card (a 256mb 9550) in games like CoD2 and GTA:SA.

The problem I'm having though, is every once in a while (every 15-30 min or so), my screen goes black for about a half second. It does this in gaming as well as when web surfing. Otherwise, the card runs fine.

I did try updating my chipset drivers, as well as adjusting my refresh rate from 60hz to 75hz. I still get the black screen flash. I installed the disc that came with the card first, then downloaded and installed the latest Forceware drivers. Before removing the ATI card, I ran the ATI driver uninstaller to remove all ATI related stuff.

The box for this card (see pic) only lists it as an 8x AGP card (not 4x/8x), as does the evga website. This is why I'm wondering if that's the cause of the black screens.

Would an 8x only AGP card work at all in a 4x only motherboard? 14-130-220-06.JPG

Any ideas?

I'll check back after work. Thanks!

From this link, you can see that they are not always compatible. http://www.neoseeker.com/Hardware/faqs/kb/10,63.html However, your video card says it is AGP 2.0 compliant http://www.evga.com/products/pdf/N350.pdf And your chipset says that the interface is compatible with AGP 8x http://www.intel.com/products/chipsets/845pe/ So, it would appear your hardware should work together.

Did you try running dxdiag yet?

If it's working at all, it's compatible. You plugged it in, right?

Thanks for the links. I had already looked at both the evga page and the intel one, and it did seem like it should work, but I wasn't sure until I found this:

It looks like, according to Nvidia, there should be no problems running an 8x Nvidia card in a 4x slot...

NVidia AGP 8x press releaseCompatibility: ...(all) NVIDIA AGP 8X graphics solutions will be able to detect the AGP level of the host system, and automatically configure the AGP interface to run in 3.0 mode (at 4X or 8X speeds), or in 2.0 mode (at 2X or 4X speeds). Therefore, a new NVIDIA graphics solution will be fully capable of 8X speeds, and will be completely compatible with 2X, 4X, and 8X systems. The NVIDIA-based cards will automatically deliver the maximum speed supported by the host system.

From: http://www.widowpc.com/pdfs/AGP8X_92502v1.pdf

As you mentioned, it may be that my motherboard, for whatever reason, just doesn't like this card. The black screens are annoying though since the card works flawlessly otherwise.

And I did run the direct-x diagnostic tool already, all the tests performed properly, and it said the video card had no problems.

I may try pulling out the card and reseating it, as well as the power cord feeding it. But, I presume it's already seated properly or it wouldn't work well or at all.

I'll probably try to find a relatively cheap, yet decent 8x agp motherboard that will accept my 2.53 Ghz Northwood series Pentium IV. But that's just more hassle than I wanted to deal with for a pc I will be giving away in about three months when I finish buying parts for my 1st build. I just wanted to make this rig a decent gamer for my 7 yr old daughter's Sims and Harry Potter type games. It might be easier to just put the old card back in and sell the 6600gt.

I'm not sure if this helps diagnose what's going on to cause these black screens for a second, but I just realized a minute ago that everytime I right click on a video file, the screen goes black just like it has been doing randomly.

If it matters, it's last night's Lost episode in .avi format ~350mb as well as some other tv show .avi files. Just right clicking, not selecting anything.

Video codec conflict?

I had quite alot of stuff bought over the times, which simply had production errors. Give the card back, and try to get it replaced. If you can, i would anyway give it back, invest 40-60€/$ more money and get a 6800 GT, which is fast enough to handle Far Cry/BF2/CoD2 on all high with anti alialising.

I may try to return it to newegg, but I suspect the card is fine. I'll probably pull it tonight and test it in my daughter's pentium III pc to see if it works in that one.

As for getting a 6800gt, I'm just upgrading this pc before giving it to my daughter, and building myself a new rig with a 7800gt. A 6600gt is plenty for a 7 yr old, I would think. But I appreciate the suggestion. :)

I just thought I'd update this...

I stopped getting the black screens about 5 or 6 days ago. The only thing I can think of that's different is that I am using the DVI output to a 19" LCD instead of the analog output to my old CRT monitor.

I'll find out for sure if it has something to do with that in a few months, as the LCD is meant for my new build, and this rig/gpu will end up running the CRT monitor again. Perhaps I'll try the using the DVI out with the analog adapter.

Yep, use the adaptor, I have no choice with my 7800GTX as my LCD is standard VGA connector and my card only had two DVI outputs.

Adaptor works fine. :)
