Carrier Board Example - Bedrock R7000

Bedrock Cartridge

The Block Diagram above relates to SolidRun Bedrock R7000 Carrier Board which is called NIO (Networking and I/O board).

As part of developing a Custom Carrier board for the Bedrock  SoM, it’s recommended to take a look at the Bedrock Cartridge which is designed and used in our Bedrock R7000 product.

HeatPlate Screws

In addition to our advanced thermal solutions, we are excited to offer a proprietary development in hardware assembly — specialized nuts (SolidRun P/N: MCH00462) designed specifically for securing the heatplate to the CPU in our System on Module (SoM). These nuts have been engineered for optimal thermal contact and mechanical stability, ensuring that the heatplate remains effectively and securely attached, enhancing overall thermal management. We make these specialized screws available for purchase alongside our SoM, providing a comprehensive solution for high-performance and reliability.

Back view: 

Same four nuts also can be inserted through the cartridge:

Note: Phillips #0 cross screwdriver is needed for this type of nuts.

Note: All differential pairs are 90-Ohm, the rest are GPIOs/Single-Ended signals which are 50-Ohm by default.

Thermal Dissipation

• Thermal grease on Cartrridge:
  We apply thermal grease on certain spots in the Cartridge in order to cool down certain parts on the SoM, such as Inductors and ICs. we recommend placing the thermal grease (white) in the following places:
  

  

• Thermal paste on HeatSink and Thermal Pad on NVME:

  The following bottom view of the SoM shows the recommended places for placing thermal paste (on the SoM’s heatsink (gray), in addition to thermal pad on the NVME (blue):

  

• Liquid Metal:
  In SolidRun’s continuous efforts to optimize the performance and reliability of our System on Module (SoM), we have integrated an advanced thermal management solution. This feature employs a specialized liquid metal compound applied directly to the CPU, significantly enhancing thermal dissipation efficiency. While the specifics of this liquid metal technology are proprietary and cannot be disclosed publicly, we are pleased to offer it as a standard part of our SoM. This approach ensures that our customers benefit from reduced thermal constraints and improved performance without the need for separate implementation or additional thermal management strategies.

Power Consumption

SmartShift Technology for Optimized Power Management

One of the key features of our System on Module, integrated with AMD Ryzen™ processors, is the SmartShift technology. This innovative feature allows for dynamic adjustment of power allocation between the CPU and other system components. By intelligently shifting power where it's needed most, SmartShift enhances overall performance and efficiency, making it an ideal solution for power-sensitive applications.

Controlling CPU Power Consumption

With SmartShift, you can precisely control the power consumption of the CPU, tailoring it to fit the specific needs of your application. This capability is especially beneficial in scenarios where power efficiency is crucial, such as in portable or battery-operated devices. You can set a limit to the CPU power consumption, for example, capping it at a specific wattage to balance performance with power usage.

Configuring CPU Power Limits in BIOS

To configure the CPU power limits, you can access the BIOS settings of our System on Module. We provide a detailed guide on how to navigate these settings and effectively set the desired power caps for your application.

For step-by-step instructions on accessing and modifying these settings, please visit our detailed BIOS configuration page here: Bedrock V3000 BIOS Settings - Power Screen.

By leveraging the SmartShift technology and configuring your CPU power settings via BIOS, you can optimize your system’s performance and power consumption, leading to a more efficient and tailored usage according to your specific requirements. This section of the manual ensures that you have all the necessary tools and knowledge to take full advantage of the innovative features provided by our System on Module.

To demonstrate the efficacy and benefits of the SmartShift technology in our System on Module (SoM), extensive measurements have been conducted using a SoM based on the AMD Ryzen™ 7 7840HS processor paired with the Bedrock R7K Carrier (NIO). These tests were aimed at validating how effectively SmartShift manages power distribution under various operational conditions.

SmartShift Configuration Parameters:

The SmartShift feature is controlled through four key parameters in the BIOS Power tab, which allow for precise management of power distribution and consumption:

• APU Only sPPT Limit: Sets the peak power limit that the Accelerated Processing Unit (APU) can consume.

• Sustained Power Limit: Defines the sustained power threshold for long-term performance stability.

• Fast PPT Limit: Regulates the rapid power allowance for short bursts of intensive processing.

• Slow PPT Limit: Controls the lower power threshold, suitable for maintaining efficiency during less demanding tasks.

Measurement Results

The following table illustrates the power consumption results (in Watts) observed under various settings of these parameters. These measurements provide clear insights into how SmartShift adjusts power usage dynamically, ensuring optimal performance and efficiency across different workloads and operational states.

The tests outlined in the table above were conducted while the system was running CineBench R23, specifically utilizing the Multi-Core test mode. This benchmarking tool is widely recognized for its ability to stress multiple CPU cores simultaneously, making it an ideal platform for evaluating the performance of the SmartShift technology under high computational loads. By conducting the tests in this environment, we ensure that the measurements accurately reflect the capabilities of SmartShift to dynamically manage and optimize power consumption during intensive processing tasks.

Power Input

The recommended input range for the SoM is 12V-24V.
Note: there is no reverse polarity protection on the SoM, please be careful not to confuse between the “+” and “-” signs. (Red is Positive “+”, Black is Negative “-”)

SolidRun uses Molex 1053071202 Connector to interface between the SoM power input and the Phoenix Connecter.
