Windows 95 Boots in 6 Seconds on Ryzen 9 9900X

Windows 95 on Modern Hardware: A Surprising Feat

Running Windows 95 on a modern computer might seem like an unusual experiment. However, a user known as O_MORES successfully booted this 30-year-old operating system on a state-of-the-art AMD Ryzen 9 9900X processor in just 6 seconds. This setup highlights the remarkable adaptability of older software and the power of contemporary hardware.

Context / Why This Matters

Windows 95 was released in an era when computing power was vastly different from today. The minimum requirement for Windows 95 was a 386 processor running at 20 MHz, which is a far cry from the Ryzen 9 9900X's 4.4 GHz per core. The original hardware had limitations that are irrelevant under modern conditions, but running Windows 95 on a modern processor provides an excellent benchmark for comparing hardware capabilities.

Main Discussion

The Hardware Setup

The build uses an AM5 motherboard, 64 GB of DDR5 RAM, and a blazing-fast Gen 5 NVMe drive. This combination of cutting-edge components ensures that the system can handle demanding tasks with ease. The Ryzen 9 9900X, with its 16 cores and 32 threads, is an overkill for Windows 95, but it demonstrates the versatility of modern processors.

The Boot Process

Booting Windows 95 on this modern hardware is surprisingly fast, taking only 6 seconds. This speed is largely due to the small size of the operating system, which installs in about 50 MB. This small footprint allows the entire OS to fit easily into the processor’s memory cache, significantly speeding up the boot process. Despite the advanced hardware, the OS only recognizes 1.8 GB of the available DDR5 RAM, a limitation inherent to its design.

Compatibility Challenges

Running Windows 95 on modern hardware poses several compatibility challenges. The OS was built for a completely different era of computing and can only recognize a fraction of the available RAM. Additionally, it runs on a single processor core, which is a significant limitation given the multi-core capabilities of modern processors. To get driver support working, the setup required custom patches, legacy PCI adapters, and an old Nvidia GeForce 7900 GS graphics card. The Ryzen 9 9900X also had to run at a limited 4.4 GHz, as Windows 95 can crash on CPUs that are too fast.

Practical Tips

If you are interested in running older operating systems on modern hardware, there are a few key takeaways to consider:

• Custom Patches and Drivers: Be prepared to use custom patches and legacy drivers to ensure compatibility.
• RAM Limitations: Understand that older OSs may not recognize all available RAM, and plan accordingly.
• CPU Speed: Modern CPUs may need to be throttled to match the capabilities of the older OS.
• Hardware Selection: Choose components that are compatible with the older software, such as using an older graphics card for driver support.

Important Takeaways

Running Windows 95 on modern hardware underscores the vast improvements in computing power over the past three decades. The 9900X is roughly 280 times faster per core than the 386 processor that was the minimum requirement for Windows 95. This experiment highlights the broader concept of comparing and contrasting hardware performance across different generations.

Conclusion

The ability to boot Windows 95 in just 6 seconds on a Ryzen 9 9900X processor showcases the incredible advancements in hardware technology. While there were significant challenges in compatibility and performance, the successful boot demonstrates the versatility and power of modern computing. This experiment not only provides a fascinating glimpse into the past but also underscores the remarkable progress in technology.
