# RDMA Requirements

Everything RDMA needs, checked before you subscribe.

## Main PC

* **Realtek RTL8125 network adapter.** This is the one hard requirement.
  * Many motherboards from the last few years have it built in — look for "RTL8125" or "2.5G LAN" on the spec sheet.
  * A standalone RTL8125 adapter card also works.
* Windows 10 or 11.

**How to check what adapter you have:**

1. Press `Win + R`, type `devmgmt.msc`, press Enter.
2. Expand **Network adapters**.
3. Look for a Realtek entry with **8125** in the name.

Not sure what you are looking at? Send a screenshot of that list in your ticket — we will tell you straight away.

## 2nd PC

* Any computer running Windows 10 or 11.
* A normal network port or Wi-Fi.

## Network

* Both PCs on the **same router or switch** (wired is best; Wi-Fi works but wired is smoother).
* No special router settings needed in most cases.

## Plans

* An active RDMA subscription — see [privatesolution.org](https://privatesolution.org).

## What you do NOT need

* No DMA card.
* Nothing installed on the main PC besides the small helper that comes with your plan.
* No technical knowledge — setup help is included.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://guides.privatesolution.org/rdma-setup/rdma-requirements.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
