Greetings. First time poster here.
First, let me explain what I recently changed. I recently added 4 sticks of Corsair Dominator CM2X1024-8500C5D RAM and upgraded from Windows XP MCE 2005 to Windows Vista Ultimate x64 to utilize all 4 gigs of RAM. Been running great since april. Updated to the most current nVidia WHQL graphics driver 175.19 in July, no problems. Installed August's Microsoft critical updates, no problems. Until, that is, after running some flash content from YouTube...I began getting BSOD with memory dump. I could make this happen every time by playing flash content....even flash applets running on random web pages would make me crash intermittently. After each crash Windows diagnosed the problem as caused by an nVidia graphics driver. Began researching solutions and found several people recommended that uninstalling the driver in safe mode, running a driver cleaner in safe mode, and reinstalling the driver in safe mode would fix the problem. System still crashed with nvlddmkm.sys as the culprit. I began to suspect my new RAM and found some forums discussing adjusting FSB and PCI voltages as solutions to this problem. This made me curious as to the latest version of BIOS out for my mobo. After all, they do suggest only upgrading your BIOS when you are experiencing problems. I flashed my BIOS from 1701 to 2101 and lo and behold it seemed I had solved my problems. The fix lasted approximately 3 days. This led me to investigate the specific BIOS settings as I read that I may need to adjust several of my memory settings manually to make my system stable. I've found this BIOS has several intricate settings to effectively overclock your system. I've never attempted to overclock my system even though I certainly have a system which you could overclock. Although I would be happy just to get my system stable, it appears I am entering a territory which I may as well overclock while I'm there. Which brings me to here. After scanning the Asus forums I discovered that I must first load the default settings prior to changing my memory timings. Only then would it allow me to save my changes so the computer POSTs on reboot. After that, I found a setting "enable SLI memory." CMOS needs to be reset every time I try to enable that. When I try to enable SLI within the nVidia control panel, i get nvlddmkm.sys BSOD crash. I'm thinking I need to make some veeery specific changes akin to overclocking specifics. I'll have you know I am still currently researching these things diligently but any help at all would be most appreciated.
