If you have confirmed that your DDR4 memory is all okay by running memtest for days in the past, and then decide at a later time to upgrade the cpu only (from a dual core Celeron to a i7 6700 in my case)......do you still need to run memtest with the new cpu to confirm all is still okay?
Maybe a daft question.......
- Thread starter malcky
- Start date
If it is overclocked, then maybe as the IMCs are different and may not hold the same clocks.
There is basically no need to do that.
Your not changing the platform nor the motherboard and you have verified the ram is ok already.

The only exception is that integrated memory controllers on CPUs might behave differently. With DDR4-2133 and DDR4-2400 speeds following the JEDEC specs, there shouldn't be a problem. But above those speeds, there might be variations what's stable and what isn't. So a certain CPU might behave 100% error-free with a set of RAM sticks, but another CPU might give errors.
AMD's Ryzen has been very sensitive about this. Microcode updates integrated in BIOS updates are promised to deal with this (preliminary reports of the final AGESA 1.0.0.6 tests support this).
