 a couple of weeks ago, the Steam version of OCCT is finally here!

It took a little longer than originally planned, but we're very happy to say that OCCT will soon be available on Steam! This release will make OCCT more accessible to a broader audience, including gamers and hardware enthusiasts.

Even better, this release also includes a 

 While OCCT –following the Linux release– was technically already compatible with the Steam Deck, this optimized version will ensure a smoother installation and overall user experience.

 priced the same as on Patreon. That means if you're not a fan of subscriptions but would like to support us or gain access to more features, you can simply pay for one month or one year directly through Steam.

Additionally, to reflect this update, the Personal+Patreon version of OCCT will be renamed to 

across all platforms. Pricing and features remain unchanged.

Today's announcement is another step in our commitment to making OCCT available wherever you need it.

We're excited to announce that OCCT has been approved on Steam and will be available in mid-June, complete with full Steam Deck compatibility!

OCCT is officially coming to Steam

, which brought Linux users long-awaited stress-testing and monitoring features that Windows users have enjoyed for years, we're thrilled to share another exciting milestone for OCCT and the Linux community!

OCCT now comes preinstalled in the latest CachyOS's ISO!

 No extra installation, no extra steps, just boot up and get straight to stress-testing and system monitoring.

It is also an ideal solution for debugging a setup without relying on the host OS. Since OCCT is available directly in the live ISO environment, users can 

diagnose hardware issues without needing to boot into or install an operating system.

 This clean, minimal environment provides reliable results and avoids interference from background processes or OS-level conflicts.

We're proud to be included in one of the fastest-growing Arch-based distributions, and we're grateful to the CachyOS team for making this possible. This integration marks another step forward in our mission to bring powerful system diagnostics to every platform.

Tried OCCT on Linux or CachyOS? Let us know what you think, your feedback helps us improve.

 We believe in accessibility, which is exactly why we brought OCCT to Linux in the first place.

We're open and ready to work with more distributions, projects, and contributors. If you would like to partner with us, leave us a message!

OCCT is now preinstalled in CachyOS's ISO, the Arch-based Linux distribution. This integration allows users to easily access OCCT's powerful stress-testing and monitoring tools right out of the box.

First, to everyone who has been using and testing the alpha and beta version of OCCT for Linux:

After extensive development and rigorous testing, 

OCCT for Linux is officially out of beta!

 This milestone finally brings our industry-leading stress-testing tool to Linux users, ensuring robust diagnostics and monitoring across all distributions.

Basically, everything the Windows version of OCCT can do, OCCT for Linux can do too!

Comprehensive Stress Tests – Evaluate CPU, GPU, and memory performance under heavy workloads to ensure the stability and reliability of your system.

Advanced Monitoring Tools – Get real-time insights about temperature, voltage, power consumption, and other critical system metrics.

Multi-Platform Support – Compatible with major Linux distributions, including Ubuntu, Debian, Fedora,  Redhat, Arch Linux, and many more.

User-Friendly Interface – A streamlined and intuitive UI accessible to all users.

Until now, Linux users lacked a comprehensive hardware monitoring and stress-testing solution. OCCT fills this gap by providing a robust monitoring system to meet the unique needs of Linux-based setups. Now, 

users can run industry-standard tests and monitor their hardware in real time

, just like Windows users have been able to do for years.

– A personal license grants access to both the Windows and Linux versions of OCCT. Just download the version you need and get testing!

– OCCT for Linux is available as a separate license for OCCT Pro and Enterprise users. Businesses can also bundle both Windows and Linux versions at a discounted rate.

OCCT has officially released on Linux

That's right—that's the name (at least for now)! Our replacement for WinRing0 is called 0Ring (pun intended), and it's set for release in a couple of months. Designed with security and stability as top priorities, 0Ring will be a closed-source solution with the following key features: 

These measures ensure that 0Ring remains a reliable and secure alternative for the community. This also ensures that we don't run into another ban situation moving forward.

As we've stated before, 0Ring will be free for non-commercial users. If your application isn't making money, or only generates pocket change, we won't charge you. However, if you're a business or your app becomes profitable, we kindly ask for your support to sustain development.

With 0Ring's launch approaching, we're open to discussions with developers who want early access or potential collaboration. If you're interested, reach out to us!

Two weeks ago, we announced our plan to develop an alternative to WinRing0 following its ban by Microsoft. Since then, our team has been hard at work creating a new solution for the community.

AN UPDATE ON WINRING0 – INTRODUCING 0RING

In a recent move aimed at enhancing Windows security, Microsoft has banned Winring0 for a few days, a low-level driver extensively used by many monitoring, system information and overclocking tools made by the community, allowing them to access low-level information. This change has stunned many, discovering their favorite software didn't function anymore.

At OCCT, we believe that innovation must continue, even in the face of industry-wide disruptions. 

That's why we've taken proactive measures to provide a fully compliant, legitimate, and free driver replacement. Let's dive into what this change means, and how we're turning it into an opportunity to better serve the community.

The decision to ban Winring0 is part of Microsoft's ongoing commitment to enhancing the overall security of Windows.

However, it allows anyone to access any low-level function as they please, defeating any kind of security Microsoft implemented in Windows relatively recently. Drivers must be contained to their own devices/purposes, and WinRing0 is giving you access to everything.

While precious and very valuable for every tinkerer and enthusiast out there, it is a gaping wound Microsoft is trying to close forcefully. As this driver was used by a lot of applications - even by some big companies under the hood for its ease of use and to gain some development time - the grace period is coming to an end.

OCCT's Response: A Safe and Compliant Alternative

At OCBASE, we understand this risk, and actually foreshadowed it in our latest video, recorded right before the ban and covering this issue. We don't want to stay inactive when some of our beloved software are in danger.

With the Linux release of OCCT, we created our own monitoring engine. To bring it to Windows, we needed a driver. The decision was simple : make a version of that driver that can replace Winring0 all while complying with Microsoft's security policy.

We already have the certificates needed to develop this driver, and development was planned to start soon. We propose to make it available to others so they can use it themselves.

The driver will be completely free for the community. 

We stand firmly by our values : if you're not making money with your application, or even just pocket change or covering your costs, we will offer it for free. However, if you are a company, or if you start making a chunk of money with your app, we will ask you to help fund the development.

As always with our development, and also for security purposes, the driver will be closed source. We know that may be a disappointment to many, but we believe strongly that having an option here, albeit imperfect, is better than stopping the development.

Collaboration opportunities and gaining access to the driver

First, development is just started, so there will be some time for us to finalize it, and get it approved by Microsoft. If you're interested, please contact us so we can have a chat and see what we can do together !

Microsoft's decision to ban Winring0 marks a pivotal moment for the performance monitoring and testing community. We, at OCCT, are dedicated to provide a 

robust, compliant, and accessible solution 

for everyone affected by this change. We were born from the overclocking and tinkerers community. We received a lot over those 20 years. We will continue to give !

Even if for a few days, Winring, an old driver powering many useful community tools, was banned by Microsoft. We are stepping up to keep your software running!

Winring banned by Microsoft: we act to keep your software alive!

On top of the beta release for Linux, we are improving our solutions with new features to the diagnostic session and report system.

The Personal version of OCCT for Linux is now open for testing to everyone!

It offers the same behavior as the Windows version, with all its bells and whistles. Obviously, this remains a testing version, so we encourage users to report any bugs they may encounter. Your feedback is invaluable in helping us refine and make OCCT better for everyone.

If you are a Pro and wish to have access to a pro version of OCCT on Linux, please contact us for more details.

We've developed a brand-new monitoring engine for Linux! Our goal is to bring it to Windows and make it available to everyone, with free access for personal use. Stay tuned—more details are coming soon!

The report generated upon test completion is a great way to certify that a system's stability has been properly tested. Available in HTML, JSON and CSV formats, this report can now also be 

printed or exported in a simplified version.

In the HTML report, the toolbar at the top provides an 

, allowing you to share observations with your customer. These notes are included in the print version. However, please note that they are not saved within the report file itself and will be lost (or, if it exists, reverted to initial value) if you close the report.

A logo can also be added to the print report. 

This can be done by placing a 'logo.png' file in the same folder as OCCT or, if you have an Enterprise license, by injecting it during report generation via the command line.

When you're ready to share the report, simply click the 'Print' button, and your browser's print window will open, allowing you to finalize the process.

Improvements to the Enterprise+ dashboard

If you have an Enterprise+ license, you may have noticed a few changes to the dashboard in our latest update. These improvements were designed to make managing your company accounts and diagnostic sessions easier.

We have introduced a new section in the settings that 

that share access to their company license. Creating new users, changing roles, disabling accounts... Admins can now do all of this independently through the dashboard interface.

We have also improved the diagnostic session listing view by adding 

for existing sessions, making navigation more intuitive.

Finally, since the offline test report allows you to add notes, we thought diagnostic sessions should have that feature too! After opening a session, you can now write your observations, which are saved alongside all other diagnostic data. Perfect for keeping track of your exchanges with customers, both now and in the future!

We are always looking for ways to improve our services, whether through new features or UI enhancements, so you can 

expect even more changes in the near future!

Just a few weeks after the alpha release, the team at Ocbase is proud to announce that the beta version of OCCT for Linux is now available for testing and open to everyone.
