What's the difference between the memory bar, the black panel and the green panel?
Memory bar, black PCB and green PCB, no difference. It's only a preference of the manufacturer.
PCB (Printed Circuit Board), the Chinese name for printed circuit boards, also known as printed circuit boards, is an important electronic component, is the support of electronic components, electronic components is the carrier of electrical connections. Because it is made by electronic printing, it is called printed circuit board.
The color of PCB has nothing to do with the performance of the product. It's just a preference for factory design. In addition, some manufacturers launch different colors of PCB products in order to distinguish the types of products or security. For example, Kingston has launched the memory of blue PCB on the market at that time, to combat rampant fake green PCB. But Kingston was also declared, just a different color, compared to the other is not genuine, no difference.
Generally speaking, the color of the PCB board has no influence on the quality of the product, mainly the brand strategy of the manufacturer, so as to improve the overall packing effect, so as to promote the publicity. But the color is different, mostly not the same products, there is no difference in essence, but if used at the same time, green and black mix plug compatibility is relatively poor.Personal advice, or to buy green, like you before as well, even if the black performance is stronger, if inserted together if they do not come out to play, they can only work in the same pattern, rather than directly to buy green compatibility may better focus on stability.
