Boost Mode Ram Speed?

I have a Core - i5 9400f and a Motherboard with a RAM bus speed of 2666MHZ. While in Turbo Mode will this limit my CPU performance? Does the RAM speed clock up with the core?

No, it shouldn't affect it much. Remember that the Cores (which is what are being overclocked by Intel Turbo Boost) get their data through the L1 and L2 (and L3 if it exists) caches while only the L2 (or L3 if it exists) cache is actually dealing with the (speed of the) memory buses.

I hope this explanation helps; this is a complex issue and I am simplifying it a lot.
