ATI driver craps out with 8G RAM in Win 7 64bit

[50bmg]

I upgraded from 4G (2x2G) to 8G (4x2G) of matching DDR2 pc6400. Once i booted up my graphics were all jacked up. The device manager shows issues with my 2 ATI HD3870 graphics cards. It said drivers turned off due to issues. Very generic statement. I took out 2 sticks and it was ok. I switched sticks and it was ok. I only have the issue with all 4 sticks of RAM.

Is there a problem with 64 bit using 4G and ATI cards. or my ATI cards specifically. I tried both ATI 8.12 Vista 64 bit drivers and ATI win 7 64 bit beta drivers.

any ideas

50mg. I have 2 x 3870 in my personal system listed in My Config. ATI Vista 64 Cat 8.12 driver will not install and function properly with Vista 64. I also have 8GBs of RAM. Around some forums, apparently people have gotten the 8.12 to load up using Vista 64 and 4 gigs and 2 x 3870 in Xfire. I can run my system fine with CAT 8.11. Try an earlier version and forget CAT 812. Hopefully AMD/ATI will address the issues and come out with a working driver for my setup with 9.1.

I entered a trouble ticket to AMD support and this is what I got.

From review, the issue appears to be related to the latest Catalyst 8.12 as reported.

I had a suspicion it was the drivers. I tried all combos of RAM 2 sticks x 2G at a time and it worked. My mobo supports 8 gig, so thanks for confirming it.

I will try it tonight.

thanks for the help

8.11 worked fine. Win 7 is still a bit slower fps. but image quality is much better in win 7 for COD5 and Farcry.

Great. I'm using a 7900GTO with my Windows 7 BETA install. I plugged in my XP drive and now have a dual boot setup on an old AMD NF4 with a 4000+ San Diego single core. Look for ATI's 9.1 version next Wednesday, hopefully. They should fix the failure issue with the 3870 in crossfire with Vista 64 8 gigs. Should is the operative word. I'm using 8.11 in my main Vista 64 system with two 3870's.

I had about the same problem. I'm on an alienware m15x with vista 64bit. I use a ATI Mobility Radeon HD 3870 with Driver 8.57. I tryed to upgrade to 8 gigs of ram but then the screen freezes and it says an error about the display driver. My motherboard supports 8gigs and im prety sure the problem is the driver. A main problem is that i cannot find an earlier version of my display driver anywhere. Any help is appreciated!!! Thanks

Try the new version 9.6 drivers. They are faster and works for me, with 12 GB DRAM.

I am on the mobility version of the ati radeon hd 3870( I have an alienware m15x laptop). There is no support or additional drivers for this card, from either ati or dell/alienware. I have tried ussing a modded driver to get the 9.6 driver but the problem still occured. Any other ideas?/

I ended up returning the ram, and i am going to try the 8gb ram from alienware, hopefully that wil work
