I have an @ three year old Lenovo ideapad Flex 4 that came with 4GB Ram. It was never real fast, and became much slower over time. It began locking up and I had to reboot it at times to use it. I installed the 8GB Single Rank Ram from Timetec, and it runs faster and more reliable than it ever has.It took @ 15 minutes to install, and it booted right up as normal, just faster.
