iMac Memory

[Boldman]

I was thinking about getting additional memory for my iMac and I went to the Crucial site. It indicated that the memory for a mid 2011 iMac 27" i5 processor
required a memory chip with 204 Pins. When I did a memory check on the actual computer it indicated a 200 Pin chip. Which one is correct?

The current iMac's use 204 pin DIMMS. I would also recommend visiting OWC at www.macsales.com, they're very competitive on price, specialize in Macs and are second to none in customer service. You can even go an online chat or call them for technical or other types of advice.

as long as its DDR3 you should be fine. OWC (mac sales) will tell you if its compatible or not straight from there site.

If you plan to purchase elsewhere try purchasing RAM at the proper speed.

1333 or 1066, mainly because not all macs that run 1066 can run (or use) 1333 RAM, and although 1333 is backwards compatible, i'm sure you would rather get the full intended speeds of your mac.
