Installing memory cards in late 2009 27" iMac

Thanks for the quick reply. I have been sitting here waiting for some advice. I'll take your advice--to a point. I'm definitely stong emnough, but n is the plastic/vinyl? That's the question. It does seem to me that its rip-prone.

By the way, I was surprised by the amount of fine dust that was under the memory access door. Is that normal?

Okay, thanks for the reassurance on both counts. Taking my Mac to the shop would be very inconvenient, so if the tab tears, I just won't be installing the two additional cards. After all, my computer will be the same as it was before trhing to install additional memory.

I can't find your last rely here, the one about pliars, but I'll consider it. The difficulty in taking my iMac to an Apple store is simply that I don't have a car, and taking this jumbo set on an hour plus trip by buses requiring multiple transfers is not something I am willing to try. I'd probably end up dropping it somewhere. It is heavy, and it is awkward to carry. Definitely not a fun trip. I do appreciate your thoughts, though.

NOW your pliar memo appears.

Okay, I've done it. Thanks to your help, I FINALLY managed to install the two new memory cards. Was it worthwhile? I don't know yet, but I can't see any difference. I doubled my memory by increasing it from 4 to 8GBs, so you would expect to see some differences, but I don't see any so far. Maybe I will in time. In the meantime, I am really glad that I didn't try to "keep up with the Joneses" by paying $300+ to get the maximum memory of 28 GB. My additional 4GB cost about $50. That's quite reasonable for an experiment. $300 is not.

For people who have not installed memory cards and came here for support and information, I can say that their installation is easy, IF you can remove cards that need to be replaced, and IF you can get the new cards properly seated. I finally managed to do both, but it wasn't easy. I even called the company from whom I purchased the cards because I thought that I had received bad cards. I thought that because when I turned on the computer I only got intermittant beeps, so I thought that I would have to replace the new cards. That problem was fixed when I reseated the new cards. Finally, the new cards don't look the same as the cards already in the machine. I was worried about that, but the person I talked to said that different company's cards have different apearances. I guess she was right, because I'm typing this.
