With the fermentation of bloggers exposing the ideal ONE "half-axis jitter", more and more car owners and netizens are paying attention to this matter, but what is puzzling is that the colleagues exposing the ideal ONE "half-axis jitter" has not been properly resolved at present, but the relevant videos and blog posts have been restricted by the platform. The pictures show that the relevant videos and blog posts released by it are "currently non-publicly visible because they contain illegal information", but they have not been published, specifically because of the violation.
In addition, according to the previous "fat brother Yang Li" introduction, colleagues carefully selected, bought an ideal ONE, but now after 6 days of lifting the car, it was found that the steering wheel of the new car was crooked, and there was vibration in the driving, whether it was pure oil or pure electricity.
Later, the after-sales inspection was a problem with the rear axle half shaft, and the rear axle half shaft needed to be replaced. However, the new car has not yet driven itself, and it will have to replace the rear axle half axle, which is also difficult to accept.
Because of the quality failure of the new car, the ideal car side proposed to give the owner the car fuel card care compensation, but the owner now does not want to get any financial compensation from the ideal car, only wants to find out the fault and the truth of the matter.
The owner of the car once communicated to the manager of the ideal after-sales center:
1. Require the disclosure of the quality defects of the problem half shaft (design, material, manufacturing process)
2. For the two quality inspection departments of the new car leaving the factory and the new car delivery, why did not check the drive shaft problem with safety hazards?
However, the owner said that the manufacturer refused to publicize the details of the quality problem of the half shaft after sales, refused to take the half shaft away for third-party testing, and removed the problem half shaft without my consent, and claimed that this was a case of the half shaft. But as far as he knows, there are still riders who have the same problems as him. Avoid the importance of ignoring quality defects and quality inspection negligence, and refuse to disclose the right to know the defects of the purchased products to the owner.
The JEDEC organization today officially released the standard specification for the new generation of high-bandwidth memory HBM3, numbered JESD238.
The HBM3 standard continues to expand and upgrade at all levels of storage density, bandwidth, channels, reliability, energy efficiency, etc., including:
- The transmission data rate doubles again on the basis of HBM2, with a transmission rate of 6.4Gbps per pin, with a width of 1024-bit, and the maximum bandwidth of a single pin can reach 819GB/s.
If you use four, the total bandwidth is 3.2TB/s, and six can reach 4.8TB/s.
- The number of independent channels has been doubled from 8 to 16, plus the pseudo channel, and each one supports 32 channels.
- Supports 4/8/12-high TSV silicon perforated stacks, which will be expanded to 16-high in the future – which can be understood as an internal stack of 4-16 pieces.
- Each storage tier has a capacity of 8/16/32Gb, starting at 4GB (8Gb 4-high) and a maximum capacity of 64GB (32Gb 16-high) per storage tier.
- Support platform-level RAS reliability, integrated ECC calibration error correction, support real-time error reporting and transparency.
- Improved efficiency, the main interface uses 0.4V low swing modulation, and the operating voltage is reduced to 1.1V.
NVIDIA, SK Hynix, Micron, Synopsys and other companies have expressed their support for HBM3 memory for the first time. As early as last August, SK Hynix released the first batch of HBM3 products in advance, with a single capacity of 16/24GB, 12-high stacking, and a bandwidth of 819GB/s in the early stage, and recently increased to 896GB/s.
