I have a Lenovo M58p and it required a bios update for the ram to work on my PC but it was very easy to do !
Now I have to wait on the other order of 1 stick to arrive before I can upgrade my computer.
The added memory was a great upgrade to my computer.
Works well and easy to install.
I needed to upgrade the memory in my Dell desktop and this is what the Crucial memory finder said was required.
Incorrect memory for the application despite the advise it was correct.
Does not work with device as suggested.
