Q: how to restart Mac Pro after installing new memory?

Is the new RAM fully seated in the sockets?

DOes it work if you re-install the original RAM?

What is the spec of the new RAM?

Reset the  PRAM/NVRAM.

If that doesn't help, reset the SMC

The store was mistaken as to the memory.

You are welcome.

If you purchased it at an Apple store and its the wrong memory - be upset as they should know what to sell you.

If you purchased it at a chain that sells some apple devices - by contract they may be prevented from selling aftermarket parts that are configured for apple -but will not charge a restocking fee if they don't work.    

Purchased a WD drive configured for windows with the assurance that if it would not reconfigure for mac I could bring it back - of course with WD no problem -- on a video card - correct card - did not have apple firmware (thats how I found out about the contract deal) - but when it did not work - no restocking fee - happy days.

Very sad that Apple has to be this way.

Macs are picky about memory. Just because the memory has the same spics they may not work. Make sure you only purchase them from a place and guarantees they will work with your Mac or your money back.

OWC/MacSales and Crucial sell compatible memory. PNY does not.

You're welcome. Hopefully all is working now.
