Frequently Asked Questions

Friendly reminder: If you cannot detect the hard drive during device usage, we recommend mounting the hard drive on another host or reseating it. Please back up important data files in advance to avoid loss.

Please choose a reference plan based on your actual situation:

1. If the hard drive installed in the optical drive slot is not detected, some devices may not detect any hard drive in the optical drive slot during BIOS Setup, but it can be normally recognized and used under the Windows system. In this case, you can install the hard drive in the hard drive slot and detect it again. It is also possible that the cable connection of the hard drive bracket in the optical drive slot is loose or not plugged in tightly. It is recommended to reconnect and test.

2. If the hard disk is not recognized during the system installation process: Please first confirm whether the machine hardware supports the installation of this system, whether it is necessary to load the USB3.0 driver, and if it is a solid-state drive, whether it is necessary to load the corresponding solid-state drive driver.

3. For self-installed hard drives, it is recommended to first check and confirm whether the machine's interface supports the hard drive. If it does not, we suggest removing it and replacing it with a hard drive that has been tested and recognized by the official manufacturer.

4. If the issue of not being able to detect the hard drive occurs after normal use for a period of time, we recommend checking whether there is a problem with the hard drive interface connection.

5. Power on the computer → enter BIOS, check if the hard drive can be detected in BIOS. If the hard drive can be detected in BIOS, verify if the hard drive mode is correct and if the boot option is disabled. After making these settings, restart the computer for testing. If the hard drive is still not detected in BIOS, we recommend that you schedule a repair appointment and let the service station engineer assist you with the inspection and repair.

During the repair process of a product, software updates or the disassembly and replacement of equipment components are often involved, which may lead to electrical performance failures of the device with a certain probability, resulting in data erasure. With current technological means, although the probability is low, it cannot be completely avoided.

Therefore, at present, before officially starting to repair a device, major manufacturers require customers to back up important data in the device in advance. The same goes for DataCVG Redcore.

These important data usually include work files, personal files, important chat records, etc.

In any case, DataCVG Redcore and its service providers shall not be liable for any data loss.

If data is not backed up in advance, the potential impacts may include:

If you choose to bring your device to the DataCVG Red Core Service Station for repair, you may need to spend extra time on-site for data backup. Given the privacy of personal data, the service station cannot provide a backup device.

If you have made an appointment for our engineer to conduct on-site maintenance, our engineer will contact you in advance. If you are unable to back up your data in advance, the engineer may negotiate with you to postpone the on-site visit, or may not be able to complete the maintenance within the agreed time frame.

There are currently two mainstream methods:

Back up to a "mobile storage device" or "cloud storage".

Backup to mobile storage device:

Step 1. Choose the appropriate storage device. Depending on your personal needs, you can opt for a USB flash drive or a portable hard drive. USB flash drives are compact and easy to carry, typically used for storing temporarily accessed files; portable hard drives offer relatively more ample storage space.

Step 2. Decide what to back up. Generally, important data includes work files, personal files, important chat records, etc. You can copy the files that need to be backed up into a centralized folder, which can also help avoid omissions when dealing with a large number of files.

Step 3. Copy the content that needs to be backed up into the storage device.

Step 4. After the copying is complete, please confirm again that no files have been omitted.

Backup to cloud storage:

Step 1. Choose a suitable cloud service provider. You can make your selection based on your personal needs, taking into account the following dimensions:

1) Brand reputation of service provider;

2) Specific cloud storage functions;

3) Service fee standards;

4) Others.

Step 2. Decide what to back up. Typically, important data includes work files, personal files, important chat records, etc. You can copy the files that need to be backed up into a centralized folder, which can help avoid omissions when dealing with a large number of files.

Step 3. Upload the content that needs to be backed up to the cloud storage.

Step 4. After uploading, please confirm again that there are no missing files.

Note: Different providers have varying functions, pricing standards, and operation methods. Please refer to the official website of the service provider for instructions, as further elaboration is omitted here.

If the computer cannot be turned on normally, how can I back up?

You can prepare a U-disk or a mobile hard drive with sufficient capacity in advance and carry it with you. After reporting the repair, you can wait for the engineer to visit. Our engineer will inspect the problem for you and guide you to back up your data according to the specific situation of the device.

The host number, also known as the factory number of the host production, is abbreviated as SN (Serial Number or sequence number or service code), which is used for technical support or repair reporting provided by DataCVG Redcore.

The host number of the DataCVG Redcore device consists of a string of 6 to 8 English digits, and case is significant during querying.

1. The serial number of the DataCVG Red Core commercial desktop computer is located on both sides of the body, with some on the top of the main chassis

2. The serial number of the DataCVG RedCore rack-mounted server is located on the top of the mainframe

A workstation is typically a single-user standalone device designed for professional users, emphasizing local high-performance graphics processing, data processing, and interactive operations, such as 3D modeling, animation production, video editing, and other scenarios. Users can highly customize the hardware to meet their specific professional needs, enjoying a good local interactive experience. On the other hand, GPU servers are designed for large-scale computing tasks, supporting simultaneous access by multiple users. They are primarily used for workloads that require extensive parallel computing, such as big data analysis, machine learning training, scientific computing simulations, etc. They possess powerful computing capabilities, high scalability, and stability, meeting the needs of enterprises or scientific research institutions for centralized management and sharing of computing resources.

If the business involves individual professional creation, such as 3D design for designers or special effects production for film and television practitioners, emphasizing single-user local operation and instant feedback, with high requirements for graphics performance, and also hoping for personalized hardware adjustments to the equipment, a workstation is a better choice. If the business involves enterprise-level deep learning model training, large-scale data processing and analysis, requiring multi-user shared computing resources, and high requirements for scalability, stability, and centralized management of computing resources, a GPU server is more suitable.

Shuju Red Core uses enterprise grade liquid cooling components, with all copper cooling heads that do not produce chemical reactions or clog. The micro waterway design accelerates liquid flow through enhanced heat dissipation function. The medical grade water pump is sealed with 100% helium detection at the factory and has a design life of over 44000 hours.

The performance of a workstation is influenced by GPU performance (number of cores, memory size and bandwidth, frequency, etc.), CPU performance (number of cores, clock speed, cache, etc.), memory performance (capacity, frequency, timing), storage speed (SSD read and write speed), and cooling conditions. For example, when running large 3D scenes, insufficient GPU memory can lead to stuttering, and low CPU performance can affect the model loading speed. The performance of a GPU server is influenced by the number and type of GPUs (different models of NVIDIA GPUs have significant differences in computing power), network bandwidth (data transmission between multi-node servers requires high-speed networks), memory capacity and bandwidth (to meet large-scale data storage and reading), and server architecture design (such as PCIe bus bandwidth affecting communication between GPUs and other components). In distributed deep learning training, high network latency can severely restrict training speed.
