Ordered this crucial stick to upgrade the 4 GB RAM that came with my T470:
Casually Googled the part number with T470 and this thread came up where people claim to have issues:
Just wondering if others also have had similar issues. Haven't received the laptop or the memory stick and so not sure. If I knew that the memory sticks were this expensive, I would have just customized 16 GB RAM while ordering the laptop..

I've never used that stick but I have seen reports of similar items drawing excessive power when they were supposed to be in a low power state

Not a fan of mixing different brands/types/sizes of RAM; just not worth the hassle of possibly having issues. You also loose the speed boost of dual channel if using different sizes. In any event, I removed the 4GB of RAM from my T470 and installed two 8GB of RAM from Crucial. I just ran a test, and I am not seeing the temperature increase or large battery drain that others are seeing after going into sleep mode. Memory does not have a thermistor, but upon restart from sleep I am seeing a 4 Degree drop in all the various other sensors in the laptop (NVME SSD, Chipset and cpu) after being in sleep for 1 - 1/2 hours with ambient temperature outside the laptop being constant. Battery drop was 6% (With peak battery threshold set to 80% on both batteries).

Thanks a lot for taking the time to write, pjc123..
Sorry, I didn't make it clear. Intend to take away the 4 GB stock RAM and going to just install the 16GB Crucial. So the 4 degree temp drop and 6% battery drop is okay or something to be concerned about?

I was saying it is a good thing, compared to what the others reported on the post you referenced. They were reporting large battery drain, higher temps, and even physically hot when feeling the back of the laptop. I can't say definitively why I am not having those issues.

That's great to know, pjc123! Thank you for your prompt response.
Quick question while we are at it. When you mentioned that you had set the battery threshold to 80%, you did it using the Lenovo power management software, right?
Just making sure since I need to do it as well.

Lenovo Vantage is used to set battery threshold.
