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.

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.

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!

I bought PNY OPTIMA 2GB (2x1GB) Dual Channel Kit DDR 400 MHz PC3200 for my Dell Dimension 3000. So I went from having 512MB in RAM to 2 GB. My PC is not freezing anymore and I can use it while my antivirus is running.

I just wanted to say that I bought a PNY 1GB memory strip from Best buy which was suggested by the Geek Squad and it worked so well that I came across the info that Amazon had some new ones for half the price, so I bought another one. Now I am 2 GB strong, maxed out and very satisfied. I noticed that someone stated PNY was crap, not true; if you know what you need and buy the correct part you will be satisfied. Some people don't buy the correct parts and put blame on the manufacturer. In addition, I bought a GeForce 860 video card with the PNY name on it as well and it is awesome! Thanks for your time!

I popped them in, no problem. For about four hours operating time, they were great. My seven-year-old PC worked like new!

Then, all of a sudden, I started getting crashes, fatal errors, emergency memory dumps; the computer became nearly unusable. Every web browser crashed within a minute.

I pulled out the new memory and computer went back to normal. Requested refund and am returning to Amazon.

Upgraded my HP a1330n from 1GB to 3GB.
No problems installing (just popped them into the two open slots).
It was immediately recognized and now my system boots faster and performs better. Other than getting spyware off your PC, upgrading the RAM is the best thing you can do to make it scream. Two thumbs up.

Installed fine had to make minor adjustments to get the full speed but the only thing I hated was I didn't get a proper receipt the receipt I had said I ordered a bunch of porn and books that I wasn't familiar with which seemed it was addressed to some woman because it was for women.

Really wasn't planning to return the memory anyways after some adjustments to the cpu everything runs cooler and faster then the older memory I had. The old 2x512mb GEIL modules had BSOD and heat problems so I had to give them away.

These modules are mixed with lifetime memory 2x1gb modules I was expecting problems but they didn't show up only had to change CAS frequency to 3 and I had the full speed.

Oh well more RAM for videomemory then because of the chipset limitation.

Really its not a bad thing to max out your RAM to 4 GB it will use the excess for your videocard and if you have a newer videocard it will utilize the memory better for applications so everything will be faster.

This is an older Emachine model T6212 with amd 3800 dual core and an western digital 320 gb drive and an MSI 4830 videocard

Running 64 bit Windows 7 but please be aware of the chipset limitation!
