Why doesn't the part number of the RAM match the label?

Question

AMD

Hello. The other day I bought AMD R9S416G3206U2K memory. The label says part number R9S416G3206U2K . However, all test programs show a different part number: R9S48G3206U2S . This is a different memory, a different product. Why?

Answer 1

Everything is fine with you. They didn’t sew up the bar (but should they?) The fact that they are going to sell it in a set of two.
The last letter in the label is pretty obvious: K=kit, S=single.
You can stick different markings on the same planks and sell them either individually or in pairs.
Simple marketing.

Answer 2

See volume. If the die has 16, then everything is ok.
If 8, then you were thrown.
