I have installed 2 of these modules in a Lenovo Thinkpad E470, i7-7500U. Compatible according to relevant sources. The only problem is that the effective clock frequency of the RAMs constantly changes back and forth between 665 and 1065 MHz. HWi and CPU-Z reflect this equally under W10, 1903. Additional info: - BIOS latest v2.00 - Speedtest deactivated (CPU works constantly on highest clock frequency) - both RAM modules are new and identical - Memtest86 and Win memory test do not give any errors Does anyone know anything about this?
