Is possible with most modern laptops thanks to Flex mode

But will have minor performance penalty with ram-heavy applications like Games

For TS:

For modern ddr4 systems, not only same rank and clock speed, but also need to make sure the CAS latency timing is also the same

Do not match the Hyperx/fury with tighter timing with the normal OEM ram with normal timing, may cause compatibility issues like not detecting additional ram or running at lower speed than specified

But its okay to match normal/VALUE/KVR ram with OEM ram with same rank/speed on laptops
