DDR4 Stupid Question (probably)

I have a question regarding listed speeds of ddr4 memory. I have read that everything over 2400mhz is in fact OC memory. So if I am taking that right, if you buy a 3200 kit it's been tested by the man to run at that speed oc'd. My question is this, so is 3200mhz memory just overclocked 2400mhz or does it have better chips power phase etc???

All modules are binned at the manufacturers factory to ensure compliance and to match modules.
Each module is tested to determine its highest stable clock frequency and accompanying voltage and temperature when in use.
The potential for Overclocking is not normally tested and therefore not guaranteed. When there is a high demand for a particular batch then some higher binned modules are released to maintain supply/demand and if your lucky and get one of those kits, you can Overclock higher than it's rated SPD. In this case you've got the modules that bin-out "hot," with a higher frequency/voltage tolerance than the target SPD.

Actually the thing about rams being advertised and sold to be higher than 2133MHz/2400MHz are all above JEDEC specifications(which are specs you see for stock ram IC's). When you look at the overclock's themselves, they are guaranteed to work outside the box since they've been binned, tested and stressed to operate at the designated voltages and latencies.

You should be able to see that the higher the binning from the factory the higher the quality and it's subsequent price. Please be aware that the rarity of the kit can and will up the price(and often it's not because of the higher quality but lack of stock in the inventory).

You could try to OC but yes normally they would sell it for more if they were able to run it stable (based on the vendors test) however sometimes it more of a demand issue. So if they need more 2400 chips then even if it can go higher they will sell it at 2400 since they may have a contract to fill say with amazon or something.
