My G400MAX + K7M w/K7-500@800Mhz is very stable with; force AGP x2 and 5.50.005 Drivers

I had problems with 5.50.1 drivers, so try that. Also boot into safe mode and check for ghost (duplicate) drivers and remove 'em

Good Luck

I could get my comp to work in 1x if im lucky enough to bypass the mobo cold boot freeze but like i used to use the old drivers and got the same problem, the thing is i cant get the card to run at agp 2x, even on my own system.. and how the hell did u get 800 mhz omg =P

First you need the registry hack to force AGP 2X. Then to fix the cold boot problem use regedit to change the "AGPFallback" string from "0" to "1". AGPFallback is located at > [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Class\Display\0000\Settings\CPU] This is what is making it run at 1x.

I'm running a K7 650 @715 with a G400Max using the latest 5.50.10 beta drivers. I recently updated the M/B bios to beta 127 (which is stable BTW). Also Asus has released their version of the update Busmaster and AGP Miniport drivers. You problably already have this installed, but a "reinstallation" might not hurt.

Some other little things you might try are: Disabling the "ClkGen for Empty PCI Slot/DIMM" in bios, and do the same to the Spread Spectrum ClkGen; Make sure your VIO jumper (on the M/B) is set to 3.4v; Try disabling Advanced Power Management altogether.

The part that baffles me is why your G400 "couldn't run" in AGP 2X mode on the BE6. I was running mine on a BE6 for a couple of months at 2X with no problems. I'm unsure if this indicates a problem with this particular board? Don't quite know what else to suggest.

Have you tried to replace your power supply? Is your Athlon a .18 or .25 version? I'm running the K7M+G400 MAX with ZERO problems with the 5.50.10 beta drivers. BUT, I did have to track down a decent 300W power supply. Also, check your memory, cheap memory can sometimes cause the problems you are seeing. Also, check your BIOS version, you should be using 1007, or 1209(which I use). BIOS versions older than 1007 do NOT work properly and were the reason for MOST reports of K7M problems.

I dont have a problem loading in 1x and 2x agp but the thing is that it locks in cold boots in agp 1x and just freezes randomly in agp2x, my card cant seem to work in agp 2x in any system =( i think i have a bad card, and i bought the card from emo in some other msg board =(

Right, I have an Athlon 800 running on a K7M motherboard with a G400 MAX. It took a bit of time, but I have a system that runs everything - direct3d, opengl etc. perfectly. Firstly, you might need the Beta bios which can be found on asus' web site (http://www.asus.com). If you go into the support section, find the section about problems with running the board with the faster Athlon chips. This will point you in the direction of the Beta bios (km126.zip). I had no end of problems before installing this, but it may just be because of the speed of my processor. Secondly, go into your bios. Ensure that Plug and Play operating System - under the plug and play section is set to no. For some reason, when I let Windows handle the IRQ assignments, the machine boots into Windows, and promptly crashes with a load of garbage on the screen - sounds similar to your dots problem. There seems to be an incompatability between the AMD AGP port driver and the plug and play aspects of Windows since this only happens with this driver installed. Unfortunately you might find with this setting that you cannot get the G400 using a non shared IRQ. Mine seems hell bent on sharing with my DVD decoder, This doesn't seem to cause any problems whatsoever, so I'm not really bothered. Thirdly, install a fresh version of Windows 98 - I'm using SE so I cannot account for other versions. Fourthly, install the relevant drivers from the K7M CD - the AGP port driver. Finally, install the latest Matrox drivers - I find that the beta drivers work absolutely fine for me - remember to install the separate Turbo GL driver at the same time. If all goes well your system should run fine without having to tweak AGP settings etc. If it works on my machine - which is packed full of cards - adaptec uw scsi, sblive, sbawe32, creative dxr3 decoder, zoom modem then hopefully it should work with yours.

Now im getting random reboots and user.exe and gdi.exe errors... well im gonna reinstall windows more, i've already gotten all the latest drivers but i'll try those k7m bios updates too... i hope i dont **** up

The "final" BIOS for the K7M has come out, ver 1008 I think. Check www.amdzone.com for details.

Okay I'll try the new bios but someone emailed me saying they had the same issues and just replaced the ram so i dunno, could it be maybe i got a really old test board of g400? cause i did get it really early, about when the reviews on sites started popping up... well anyways is there anyway for me to test if its the ram without buying new ram. also i formatted and reinserted everything again and everything was working fine until i installed quake 3 (which installed direct x 7) and thats when everything started freezing in desktop and games and stuff, so I'm thinking its the direct x 7 trying to access something and i dunno, well i disabled AGP in the direct x 7 setup and well i get less lockups in desktop, but gaming is still an impossibility, well thanks for all the help guys, keep throwing in suggestions! =P
