Why doesn't the United States digitize its currency

1. What is the inevitable connection between economic control in several families and virtual payment?!

2. It doesn't matter whether it is or not. The development of a token based on blockchain is only 10000 or 20000. Yes, what if not?

3. No, it's just digitalization. In addition, the US dollar is an international currency. Even if there is digitalization of the world currency, it will not end so soon. After all, its international influence and status are not so easy to shake.

Dog money soars, is it reliable to buy virtual currency? In fact, how can we say that the combination of virtual currencies is not reliable? Because virtual currencies are all hyped by others. Virtual currencies are hyped by some people in order to make money, so they are totally unreliable. But if you can cut a wave of leeks and leave, it is also a very reliable thing. In fact, for the vast majority of people, It's better not to touch the virtual currency. If you don't withdraw the virtual currency in time, you will be ruined. But if you want to take a chance, it's OK, because it's also a very lucky thing for many people to leave after making money{ RRRRR}

generally speaking, virtual currency is actually owned by others, so it's better not to touch it, because many people can't control their own desires, and they don't have many virtual currencies. In this way, the gain is not worth the loss. Originally, if they just wanted to play, they would be ruined, which is the tragedy

5. The SSD with ordinary m.2 interface takes the SATA bus. The highest sata3 speed is 600m / s, and the generally good one is 500 + m / s. The SSD supporting the PCI protocol can take the PCI bus. At present, JD is selling Procter m.2 PCI series, with the capacity of 128G, 256g and 512g. The read and write speeds are 770 / 335, 770 / 580, 770 / 625 respectively. It can be seen that the read speed supporting the PCI protocol is much higher than that of the SATA protocol, But at present, the price of SSD that supports the PCI protocol is much higher. You can start with the money. I don't think the difference in daily use is very big. The above personal experience is for reference. Thank you!

6. SerDes protocol only realizes the conversion of high-speed serial data signal to parallel data signal, which includes 8B / 10B coding, data boundary detection and other functions
PCI protocol is a complete protocol, including physical layer, link layer and so on (just look at this network), and then the physical layer of PCI protocol is implemented by SerDes protocol
usage: large amount of data and high-speed data need to be transmitted

7. 1,

sure,
PCI 1 x is the most basic unit, bandwidth 250MB / s
PCI 4x 1GB / s
PCI 8x 2GB / s
PCI 16x 4GB / s

note that PCI is full plex, compared with AGP half plex, it has two channels connected to North Bridge

one can be connected to North Bridge by graphics card alone, On the other hand, each single channel will have 4GB / s data bandwidth, which can fully avoid the performance bottleneck caused by bandwidth< So the bandwidth of PCI-E 16x should be 8GB / sec.

PCI-E 2.0 also has LX, 4x, 8x, 16x. Doubling all the bandwidth of 1.0 is the bandwidth of 2.0.

PCI-E 2.0 is really a double specification compared with the current 1.0:

● bandwidth doubling: increasing the bandwidth of single channel PCI-E X1 to 500MB / s, That is, bidirectional 1GB / S

● channel doubling: graphics interface standard upgraded to PCI-E X32, bandwidth up to 32GB / S<

● slot doubling: chipset / motherboard should have two PCI-E X32 slots by default

● power doubling: at present, the maximum power that PCI-E slot can provide is 75W, and version 2.0 may be increased to more than 200W, which is still uncertain

PCI-E 2.0 bus is downward compatible, that is to say, the 1.0 interface graphics card can be inserted into the motherboard of 2.0 slot, but the 2.0 interface graphics card cannot be used on the existing motherboard<

a friend asked why the 2.0 card of 3850 can be used on the 1.0 board. The answer is as follows:

the 2.0 card can be used on the 1.0 board, but the premise is that the card does not use the new features of 2.0.

for example, the power of the interface, pcie2.0 is 225W, and pcie1.0 can only provide 75W, so many high-end cards are compatible with PCI e1.0 interface, Need external power supply ~

if there is a graphics card that only relies on PCI E2.0 interface for power supply, but does not have 6pin or 8pin power interface, then obviously it can not be used on 1.0 board

do you know what I said is clear enough

that is to say, although the 3850 supports 2.0 interface, it does not abandon the compatibility of 1.0, so it can be used normally on both interfaces

however, according to many third-party evaluations, the performance of the 3850 on PCI-E 2.0 interface has improved a lot ~

question 3, no design, just plug in the graphics card, They give priority to self checking the independent graphics card.
question 4, don't look at the boot display, use CPU-Z to test, if it is 533. Modify the BIOS, it is estimated that you have an option to synchronize the external frequency and memory

8. Generally, if there is nothing wrong with social security, you will not call casually. You can check the local social security number and call to ask if there is such a thing. Now there are many cheaters who always say that they are not trustworthy.
