Happy Computer
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
I have an old Dell OptiPlex desktop that was so slow I could drink a cup of coffee before it would boot up. I was so frustrated with my desktop, I was looking for a new one. I am sure glad I looked at upgrading my RAM. I took a chance and spent a few bucks on memory. I am so glad I did this, my computer is like new. Saved myself hundreds with just a small purchase. This memory was so easy to install, just plug and play. My old cranky computer did all the rest. Look at this as an option, the chips came packaged very well and in an anti-static guard. Absolutely love this memory and was super easy to install, was up in minutes and my screen went for blury to clear. Super happy!!!

Easy install, even for a first-timer.
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
The sticks installed easily, despite having no experience whatsoever. I have never tried any install like this, never even cracked open a computer housing. This was a 20-minute install, and I even moved things I didn't have to to gain access. The two boards replaced some older, less powerful sticks. The new boards worked a treat; my tower boots faster, and performs much faster than with the old 3 GB (a1GB & a 2GB) sticks. Now that I've done this once, I want to upgrade an old laptop (and whatever else I can find around the house).

My computer is faster Yeah!!!

Exactly as described. Working great in my old old Dell Optiplex 780 pc. With only 8mb ram, Linux(Zorin), a new SSL hard drive, my old computer is much faster. I can really tell the difference. TY

Excellent Performance and Excellent Technical Support ... despite my mistakes.
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
Excellent for the product and excellent for the Crucial Technical Support. Initially I did not install the cards correctly in my HP 6005 SFF (low profile). Once the other cards are unlatched and removed, the replacement cards must be pressed straight down firmly, with as much as 20 lb of pressure, until they snap into their groves and the end latches spring up and clamp them in. Unfortunately, I was too cautious and did not press firmly enough, so each card laid on top of the contact groove, held loosely in place by the latches, which I had manually lifted up. When I turned the power on, I got five long beeps, and the power would not shut off until I held the power button for 5 seconds. Much to my chagrin, when I 'reinstalled' the original 4 cards, the five long beeps continued! I called Crucial Technical Support, and spoke with their technician for over an hour. From my description of the loose cards, he suggested I put more pressure .. as much as 20-30 pounds ... pushing the cards straight down into their slots. Eventually, the cards snapped into place and the problem was solved! The computer booted back up to my Windows 7 Desktop with no problem. The memory check indicated all 16 GB of RAM (4 x 4GB cards) were recognized by the system. Thank you Crucial Tech Support!

This is DDR3L (1.35v), NOT DDR3 (1.5v).
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
While this will work in both 1.35v and 1.5v motherboards the product page isn't exactly clear on the fact that this is DDR3L (Low Voltage, 1.35v). I think the product description should be more clear. I'm currently testing my replacement set. The first kit I got worked great for about 3 days, and even passed 4 passes of memtest86. Then after waking from sleep 10 minutes before I was going to return the PC to it's owner, it did nothing but blue screen. Another quick Memtest86 run just turned the screen red with thousands of errors within seconds. UPDATE: After 2 days of running memtest86, Prime95, several sleep cycles, and reboots, I'm pretty confident that the replacement RAM is OK. This isn't the first time I've had problems with Crucial RAM, but these things can happen with RAM from any manufacturer. These went into a Dell Inspiron 660s, which unfortunately only supports running them at 1333MHz even though the original RAM was also 1600MHz. I went with the low density (chips on both sides) version because I read that there would be less potential compatibility issues and better performance.

Wanted more performance from a standard PC
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
I liked the price and specifications of this RAM, since it matched the PCs specs. It was easy to install and was recognized by Windows 10 without an issue. With the addition of an SSD, this PC is much easier to work with. I don't do gaming, so that was never an issue for me.

CRUCIAL IMO, IS THE HIGHEST QUALITY MEMORY FOR THE PRICE
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
Upgraded a Dell OPTIPLEX 390 (Windows 10-64) from the no-name 4GB RAM to this 8GB Crucial RAM. NIGHT AND DAY performance increase. It is my opinion that 64 bit systems should never run less than 8GB, and I also believe that all RAM is not at all the same level of quality. This OP390 gained a near solid state HDD performance increase with this upgrade. Your mileage may vary, but the supplier of the PC had some no-name chicom RAM, not factory DELL RAM installed, so I am certain that did not help the performance, as purchased. Crucial is an OUTSTANDING product, and worth a few extra bucks for it.

Works on my Dell Optiplex 780 DT
Style: Memory
Size: 8GB Kit (4GBx2) Dual Ranked
Hi My Mother Just recently bought me These 2 4GB Memory Sticks. My Dell OptiPlex 780 Dt is running Really great now. I discovered that for some other people to know. You have to first remove all your memory sticks from your computer, then just install the new Crucial 4GB sticks in Slots 1 & 2 with leaving slots 3 & 4 empty. My Computer wouldn't boot up with the 2 4GB & 2 2GB in the my computer. Once my Computer Booted up and I signed in on the 2 4GB Memory sticks I then shut off my computer and installed my older 2 GB sticks in Slots 3 & 4. My computer booted up and I saw a total of 12GB of Memory installed. I included a Diagram of which slots are which in my Computer. I hope this helps others if they have a booting up problem. THANKS, Crucial & Amazon for having this Item! I plan on Buying 2 More 4GB sticks for a Total of 16GB in my computer. Thanks again, Sincerely, Billy.
