Well, I upgraded the processors in my Mac Pro last Saturday to two 5355 quad cores. Before doing that, I upgraded the firmware and my machine now reports that it is a 2,1 instead of a 1,1. Processors went in fine, and machine recognizes them and all eight cores. This brings my final configuration up to:
2 5355 quad core Xeon processors @ 2.66 Ghz
24 GB RAM
ATI Radon HD 4870 GPU with 1 GB VRAM
1.25 TB Fusion drive
OS X 10.9.2 (Mavericks)
All was running well and I put it through it's paces for the rest of the day with no problems. Then the next day (yesterday) I decided to install a Windows 7 VM under Parallels Desktop 9. I gave the VM the following configuration:
4 cores
8 GB RAM
100 GB disk.
Install went fine, and completed in about 30 minutes. Then I started loading the updates. I thought they would never end. It took at least 5 hours and countless reboots to get Win 7 up to date, but again, everything ran fine. I decided I wanted to run Windows Performance Index and see what Windows thought of the hardware I installed it on. It all started well and good, but towards the end of the tests, the fans in my Mac Pro switched to high gear, and I thought it was going to take off, it was so loud. I tried to cancel the WPI, but the Mac had frozen solid, and I ended up having to manually power off. I let it sit for a while, and when I powered it back on, it booted, but the fans were still running at full speed. I did some research and found that probable cause for the fans was the SMC needed to be reset. I reset it, and the fans are running normally again now, however I haven't attempted to bring Windows back up for fear it will happen again. Any idea what went wrong or any suggestions? Any help is greatly appreciated.
