The cheaper modules on which the ICs used are not dictated by the specifications generally use whatever the manufacturer was able to source for the cheapest price at the time.is it indicated in the product code/label?
so if it doesnt work it will usually be unstable as you go up, or chance of frying the memory, but not the memory controller right?
This means that it is not unusual that the ICs vary between the different batches. Some manufacturers have an identifier which specifies the memory IC model on the sticker, however the bulk modules generally don't.
Crucial mainstream models are always using Micron ICs, since Crucial is owned by Micron. There are some high-end Ballistix models which use Samsung ICs, since Micron themselves don't have anything available for high frequencies at competitive timings.
Kingston (ValueRam / HyperX) is generally Micron or Hynix based, only certain high-end HyperX models use Samsung ICs. Corsair meanwhile uses pretty much everything (Hynix, Micron / Spectek, Samsung), unless the ICs are dictated by the specifications.
G.Skill is nearly always either Hynix or Samsung, regardless of the model.
There won't be any physical damage to the hardware from memory overclocking, unless you increase the voltage to insane levels (on DDR4 1.5V or above).
