[QUOTE="elpepo31, post: 1637004, member: 342482"] :Angry:My Problem: RAM not being recognized after upgrading video card 2006 MAC PRO 1,1 Dual 3.0 GHz 10GB RAM I have had my MACPRO since 2006 bought it brand new, and a couple of years later I added memory from OWC (MacSales now) and it has always performed like a champ, never had any issues wit it until last week. I have Windows 7 (32b) installed via boot camp on it (relevant FYI). Last week I installed a Radeon HD 5770 on it and when I tried to boot it up it didn’t boot and I noticed the power on LED was blinking. After some frustration with the video card I finally realized that it was the memory causing the issue which is weird to me because I never had any RAM issues and I didn’t touched it at all when I exchanged the video cards. I tried putting the original Video card back, tried cleaning the RAM slots, rearranging the RAM (in matching pairs) but nothing worked. I finally got the computer to start up but only showing 2GB of RAM out of the 10 installed. Even weirder I booted up in Windows and in Windows I can see all 10GB of RAM. What can be causing this? I don’t think is a physical issue since the memory is recognized in the windows side. Any help will be appreciated Ps. I ran MEMTEST and it didn’t report any issues [/QUOTE]
