Works fine but watch out

The memory works fine, however the fact is I had to buy it because Dell didn't return a the memory upgrade that was in the computer when I sent it in for repair. If you upgrade memory in your computer, take it out before you send it to Dell for repair.

Worked Fine

I have no real complaints about this memory. I did have an issue with my PC first recognizing it but I think that had to do more with it not being the same brand as the other original sticks that were installed.

great product and meet my expectation

The specs of the computer I put in: Dell XPS 8900 with Intel i7 6700. I removed the old RAM because of different clock speed and found it surprised the system recognized the new RAM at speed 2667MHz (I read somewhere saying the speed would have been capped at 2133MHz because of the motherboard). I listed the info in hope to help someone out there who is also looking to upgrade with similar specs.

Good Budget RAM

The RAM works great! No compatibility issues. Doesn't look fancy so probably shouldn't be used in a case with a window. Great RAM from a great company! I have always trusted Crucial!

Memory sticks

Memory sticks were out of stock when I purchased, but they arrived fairly fast 3 or 4 days after. They work perfect.
