- Rising RAM prices driven by generative AI demand and economic conditions have made PC upgrades significantly more expensive in 2026.
- Virtual RAM (virtual memory) on Windows 11 uses a portion of storage drive space as extended system memory, but runs 10 to 100 times slower than physical RAM.
- Testing shows virtual RAM can help keep systems stable when physical memory is exhausted, but introduces noticeable performance degradation for demanding workloads.
- The feature is best suited as a temporary measure for older PCs with limited memory, not as a substitute for hardware upgrades.
What Happened
ZDNet published benchmark testing results on April 4, 2026, examining whether Windows 11’s virtual RAM feature is a viable alternative to purchasing physical RAM during a period of elevated memory prices. The testing found that while virtual memory can prevent system crashes when physical RAM is exhausted, it introduces substantial performance penalties that make it unsuitable as a long-term replacement for hardware upgrades.
Why It Matters
RAM and PC hardware prices have surged over the past seven months, driven in part by increased demand from the generative AI industry and broader economic conditions. These price increases have made upgrading or replacing older computers significantly more expensive. While RAM prices have recently begun to decline slightly, memory hardware remains well above historical norms. Virtual RAM offers a zero-cost software workaround for users who cannot afford physical upgrades.
As Lenovo has described in its documentation, virtual memory “creates the illusion of a larger, continuous memory space,” allowing a PC to handle workloads that would otherwise exceed its physical memory capacity. However, because virtual memory relies on storage drives rather than dedicated RAM chips, the speed difference is substantial.
Technical Details
Physical RAM operates at speeds measured in gigabytes per second, while even the fastest NVMe SSDs used for virtual memory operate at a fraction of that throughput. The speed differential between physical RAM and storage-based virtual memory ranges from roughly 10x to 100x slower, depending on the storage hardware. Systems using traditional hard drives for virtual memory experience even greater performance penalties.
Windows 11 manages virtual memory through its page file system, which automatically swaps data between physical RAM and disk storage when memory demand exceeds available physical capacity. Users can manually configure virtual memory allocation through System Settings under Performance Options. The operating system typically manages this automatically, but manual adjustment can help optimize performance for specific workloads.
The testing demonstrated that virtual RAM is most effective for light multitasking scenarios where a system occasionally exceeds its physical memory limits — such as having too many browser tabs open alongside productivity applications. For memory-intensive tasks like video editing, large dataset processing, or running local AI models, virtual memory introduces latency that significantly impacts workflow speed.
Who’s Affected
Users with older PCs running 8GB or less of physical RAM stand to benefit most from optimizing their virtual memory settings, as these systems are most likely to hit memory limits during everyday use. Budget-conscious consumers who cannot afford current RAM prices may find virtual memory a useful stopgap. However, professionals and power users running demanding applications will see limited benefit from virtual RAM configurations.
The broader context of elevated RAM prices affects the entire PC market, from consumer laptops to enterprise workstations. The AI industry’s demand for high-bandwidth memory has contributed to supply constraints that have pushed prices higher across all memory categories.
Enterprise and data center customers face a separate set of considerations. Server-grade systems running AI inference, database workloads, or virtualization platforms cannot rely on virtual memory as a substitute for physical RAM without introducing unacceptable latency penalties. For these use cases, the only practical option remains purchasing physical memory despite elevated prices. Cloud computing providers have also adjusted their pricing to reflect higher memory costs, passing the expense through to customers.
What’s Next
RAM prices have shown early signs of declining from their recent peaks, though industry analysts expect prices to remain elevated through at least mid-2026. Microsoft continues to refine Windows 11’s memory management capabilities, and upcoming Windows updates may include improved virtual memory handling. For most users, the practical advice remains to upgrade physical RAM when financially feasible, using virtual memory as a temporary bridge rather than a permanent solution.
