Hello, I was hoping for some feedback on how you guys might try to solve this... I have a 2008 Mac Pro with 10GB of ram. Its been running nicely for the last half decade, until recently. 2 weeks ago my main HDD kicked the bucket, so I had to get a new drive and restore the system from time machine. I was eventually successful (although I can no longer reboot without holding down OPTION), except I noticed the machine now tells me only 6GB of RAM is installed. I have not touched the RAM nor changed anything except the Bay-1 HDD. Is this how RAM fails? I was under the impression bad ram would lead to system crashes and so forth, not that it would just vanish. Any thoughts on what I should try? Thx in advance!
