Yes, it was a grey screen with the warning to restart or shut down. I could do nothing else at this point except shut down my Mac Pro.
The memory was delivered two days ago on Thursday 31 AUG 06. It was ordered from Crucial on Monday 28 AUG 06. I will call Crucial and complain. All of the other memory I've ever ordered for PCs using Crucial have been very good. I will call them on Tuesday morning. I must say that I am very dissapointed.
More than likely, I'll simply send it back and get the memory from the Apple Store on-line as I have a $30 off coupon and the purchase will only be $70 more than the Crucial memory. I really don't have the time to mess around and have lots of photo & video to process, so for me I guess its best to stick with Apple.
When it first boots up and I see the pic previews in iPhoto, the extra 1-GB seems to make a difference in speed, but its shortly after that point when opening up the pics the Mac Pro locks up.
