I know variants of this question have been asked before but I to clarify a detail I saw in another post.
I'm looking at some laptops like this Dell Inspiron, which uses a single-channel 8Gb DDR4 2666MHz RAM. The manual states that all configurations supported are 2400MHz, single- or dual-channel. (The Inspiron's i5 8265U processor supports up to DDR4-2400.)
I found this post that listed memory module specs that included the excerpt: "DDR4-2666 bridge to DDR4-2400 dual channel support (i7-8565U, i5-8265U processors)".
The wording on this is a little ambiguous. Does this mean that a single-channel DDR4-2666 can be bridged to a dual-channel DDR4-2400 (and would this have better performance than dual-channel 2400MHz RAM)? Or does this mean that the single channel of DDR4-2666 gets bridged down to a single-channel DDR4-2400 (and if so, why use the 2666MHz RAM in the first place?) And would this likely also apply to the Inspiron, even if it's not in the manual? I'm not too familiar with this "bridging," so please let me know if I'm misunderstanding anything.
