I got my 9500 yesterday and installed it.... my whole system went to hell before I could even try the mod. As soon as I installed the ATI drivers, I got "Delayed Write Failed" over and over again until my OS was totally corrupted. Now I can't even get XP to install period with the ATI card in. I put my GF 4 Ti4600 back in and everything is fine. As soon as it's ATI'd, Iget bluescreens like crazy.
Epox 8K3A+ bios 2812, Tbred 2200+, 512 MB (2x256MB PC2700) Audigy, Intel 10/100 Pro, WD 120GB, Toshiba DVD-Rom, Aopen CD-RW .. was overclocked, put it to stock to diagnose prob.
I'm gonna try to figure out what the hell is going on tonight, but I thought you guys switching from Nvidia to ATI may wanna be wary.... I lost a bunch of data, and I'm certian it's the fault of the ATI card.
I've found this scenario all over AMDMB.com, and it seems to be caused by one or multiple of the following:
1. LargeSystemCache in registry set to "1"
2. Multiple IDE devices all set for UDMA access.
3. Bad cables
In my case, 3 is false, and 1 was true. I thought that explained it, but now it doesn't apply since I can't even get XP to finish an install. I've tried addressing #2, but that didn't help either, so I'm kinda stumped. So far, I'm not impressed with ATI.
I'll post the solution here if/when I find it... if anyone has any suggestions that would be cool. Then I'll post the results of the mod attempt on my 2 9500 saphire 128MB 256bit interface cards with 3.3ns infineon ram.
