How to Select and Upgrade RAM for Building an AI Deep Learning PC

The article serves as a detailed guide to help readers choose the right computer RAM for AI and deep learning workstations. It highlights the critical role that RAM plays in ensuring smooth performance, especially when running generative AI models locally. The author explains that, unlike storage drives, RAM is a form of volatile memory that temporarily holds the data needed by the CPU and GPU. This makes it essential for handling large model files and datasets common in AI tasks.

One of the central points made in the article is the importance of RAM capacity. While 16GB might be adequate for minimal AI tasks, more serious workloads often require 32GB to 64GB of RAM. For highly demanding applications, especially those involving large models or datasets, 128GB or more may be necessary. In addition to capacity, the article discusses the importance of matching RAM to the system’s form factor—DIMMs for desktop PCs and SODIMMs for laptops—as well as ensuring compatibility with the motherboard’s supported DDR generation, such as DDR4 or DDR5.

The author emphasizes the benefits of configuring RAM in dual- or quad-channel setups. These multi-channel configurations can significantly increase data bandwidth and overall system performance compared to single-channel setups. While factors like clock speed and latency are mentioned, they are considered secondary priorities for most AI workloads. Capacity and configuration take precedence, as they have the most immediate and noticeable impact on performance.

When upgrading RAM, the article advises users to check compatibility before making any purchases. Tools provided by manufacturers like Crucial and Kingston can help identify appropriate modules. The guide also offers practical tips on installation, such as ensuring the system is powered off, inserting the RAM firmly into the correct slots, and verifying the upgrade through system tools like Task Manager or Linux utilities.

In conclusion, the article underscores that selecting and upgrading RAM is a crucial step in building an AI workstation capable of handling intensive tasks. By focusing on capacity, optimizing for multi-channel performance, and ensuring compatibility with existing hardware, users can build or upgrade a system that not only meets their current needs but is also prepared for future advancements in AI software and model complexity.

Bootstrap 3 Forms Tutorial

Image
Forms are essential for web applications, one can see them while logging in an application, editing a profile or registering for an account. Bootstrap greatly simplifies form styling by providing special style classes and providing automatic styling of form controls. To learn how to style forms and form controls we’ll discuss a registration form shown below. The code for this form as well as live demo could be seen on Bootsnipp. First things first, let’s review a basic form template. A form is placed in a .container for proper formatting. Then, in line 3 an HTML form tag is seen with a class .form-horizontal and a role form. The former is used to produce a form with labels, such as “Password” in the above image, that are on the same line as inputs, the latter is to describe meaning of the element, for example, an anchor tag can be styled to look like a button, in this case a role attribute tells that the anchor is used for playing a button’s role. After that, in line t...

Spring Tutorial: Creating a Hello World REST API Using Spring Framework and Spring Boot

Image
Spring Framework was created as a result of disappointment of Java community with earlier versions of Enterprise Java. Since then it has grown into huge ecosystem that allows one to solve every problem in building a Web-based Java application and more. Spring is often criticized because it used to rely on XML for configuration purposes. As a response to that the Spring Boot framework was released, which relies on convention over configuration principle and can do without XML at all. In this tutorial series we’ll go over how to create an application using Spring Framework and Spring Boot. While Spring Boot allows one to create an application faster, Spring is widely used today in enterprise environment and even by startups, so knowing Spring is definitely a marketable skill, and also learning it can provide one with the insight how Spring Boot works. The code for a simple Spring Framework application can be found here and the Spring Boot version here . Creating Spring W...

Getting Started with Dropwizard: Authentication, Configuration and HTTPS

Image
Here is a link to my Getting Started with Dropwizard course on Udemy. Only $10! In the previous installment of this series we discussed how to create a Dropwizard project using Maven archetype as well as how to create a simple RESTful API and access it. API security is an important topic and today we'll discuss how to use authentication and HTTPS with Dropwizard. Also, the problem of configuring Dropwizard applications will be touched. All the code for the examples below can be found here . Authentication Basic Authentication is a simplest way to secure access to a resource. It boils down to transmitting a base64-encoded column-separated pair of user-ID and password using Authorize HTTP header. If a non-authenticated client tries to access a protected resource, the server prompts the client to provide credentials, that is the aforementioned pair. Otherwise, client may supply the credentials without any prompt from the server. This authentication sch...
