Rated 5 out of 5 by from Double Check The 4GB I received from the Sales Department was the correct upgrade for my laptop. My laptop came with a 4GB card and DID HAVE any extra slot for an additional 4GB card. HOWEVER, Dell's Technical Division said my particular laptop had only ONE memory slot and therefore needed to purchase a 8GB memory card...THEY WERE WRONG. In this case the Sales Department was correct and the Technical Department was wrong.

Rated 5 out of 5 by from Wrong SIMM from Dell web site. I bought my wife an Optiplex 3060 with 8 Mb of RAM and Windows 10 Pro. The RAM was insufficient and I went through the Dell web site to purchase 8 Mb of additional RAM. The SIMM was incorrect and would not physically fit. It took 3 go-arounds with India to get the RAM returned and credited back to the credit card. I went to a local computer store, who were able to duplicate the SIMM in 3 days. Please note that the Dell web site, when given the Service Tag of the computer, properly said what the SIMM withing the computer, but gave the wrong SKU when asked for an additional SIMM. The SIMM purchased and returned was not physically correct for the computer.

Rated 5 out of 5 by from Easy to install and it helps Using Dell's documentation, it was easy to pick the RAM that matched my computer and to install it. It has helped my programs fire up faster, not a lot but still noticably.

Rated 5 out of 5 by from Easy to order the correct part for a novice. Well it worked which was my main concern as a novice. Easy to use the Dell website to find the correct part, so the fact that it was a little pricey was helped by having the confidence that it would be right and work. The free delivery helped and it only took a couple of days to arrive.

Rated 5 out of 5 by from Didn't Fit The memory does not fit my computer even though it was supposed to and it looks like returning it will cost me more than its worth! I'm very disappointed.

Rated 5 out of 5 by from Not an Upgrade I requested an upgrade. Instead, when I opened my computer to install the new memory, I discovered there was already a 4GB memory card there. Dell should have recommended an 8GB card instead. Very disappointed.

Rated 5 out of 5 by from Great product, iffy price Works as it is suppose to and fit without a problem when I put it into my sisters laptop. Directions that came on the laptop were very clear. 4 stars however cause I feel the price is to high for the product seeing as it’s a single stick of ram at its speed

Rated 5 out of 5 by from Extremely poor info on memory upgrades The Dell site doesn't offer info on how to install the extra memory, or how involved it is to do so. YouTube videos imply the battery, keyboard, CD/DVD drive and back cover have to be removed for this. Not sure I would have purchased had I know how involved/risky this is to do for the average owner.

Rated 5 out of 5 by from Not enough memory to help I was told by a Dell associate that this 4GB upgrade would expand the memory on my Inspiron 11 3000 so I could get updates to my Windows 10. This was the same memory I already had so I returned that memory to get a refund.
