Perfect - Ignore below reviewer: DOES work in Lenovo P1 Gen 22/18/2020 5:07:53 AM

Pros: -One of the fastest 64GB kits of laptop memory available

Cons: -None (at this moment)

Overall Review: I would recommend this kit, it is important to remember that when you install a new memory kit in your PC that the PC will need to train the memory. When installing this in my P1 Gen 2 it did take about 5-8 minutes to fully boot back up into Windows and had to restart several times in the process but all subsequent boots were just as fast as normal. This is a fast kit in both general speed and CAS latency and the timings are very tight. My PC has been running like a dream since this was installed.
