Good morning! It is my first post in this forum. I used to just read a lot here, and now here I am... I successfully enabled SLI in my Asus P5Q Deluxe, with 2 EVGA GTX260 Core 216 55 nm SuperClocked, but only in the second or third try. I'm using Windows 7 Ultimate x64. Just running SLI string and halmod didn't make it for me. I had to run install.cmd of halmod in the command prompt to see that new hal.dll was not replacing the old one. I had to boot in repair mode, use the command prompt and then replacing hal.dll. After that, no problem at all. Now I want to remove the watermark. I tried that "testsigning off" command, but that messes with drivers and boot. It's a definitely a no-go. If anyone has a solution for this, I would apreciate! Thanks!
