Before I ordered this product, I sent an email to their tech support just to insure that it was non-ECC memory. I received a response the same day, which was appreciated (by the way, all retail PNY memory is non-ECC in case you were now wondering). No problems with the installation. The 2GB was recognized at 400 MHz. No problems since installation.

Excellent! April 4, 2008

Dropped right into my Dell Dimension with no problems. The computer recognized it with no configuration necessary. I've been using it for a couple of months now, performance is great, and there have been no issues.

Works great! August 23, 2007
Size Name:2 GB|Amazon Verified Purchase
I replaced the original DIMM in my iMac G5 with these two 1GB modules. Although I was apprehensive about opening the case and messing with the innards, between the instructions in the iMac manual (which doesn't try to dissuade owners from swapping out their own memory), and the instructions that came with the PNY DIMMs, I was easily able to replace the one 256 MB module with the two new 1 GB modules. It almost took longer to un-plug all the lines and cables and plug them back in than it took to replace the memory.

And wow! What a difference in performance. I have over 5, 000 pictures in iPhoto, and they now load up in less than 5 seconds! Don't know why I waited so long to do this. Oh, right! The apprehension. Get over it!
