Hello! It's generally safe to upgrade your ThinkPad with another RAM module, especially if you're using a compatible socket. Since your current RAM is soldered and has a rank of 1, adding a new stick with a higher rank (like Kingston's rank 2) should work well. Just ensure the new stick matches the form factor and speed requirements. No issues with instability should arise unless there are other hardware mismatches.
You’re unlikely to encounter either issue. At the workplace, I enhanced a few E15s with 4700Us, paired with an onboard 8G RAM and 32G DR random dimms. All units operated smoothly at 3200MHz, with no complications reported. Generally, adding more ranks can make maintaining them at their listed speeds more challenging. Results might differ.
Likely okay. Earlier on a gaming laptop I had 8GB 2400 1R which was inaccessible, so I added an 8GB 2133 2R. It functioned well at 2133 with a big performance boost. For XMP it might work, but I think the risk is low for JEDEC standards most devices follow.
