Evaluate CPU and memory stability with Prime95's rigorous stress-testing capabilities.
Prime95 is a software program that is used to perform stress tests on a computer's central processing unit (CPU) and memory to determine if they are functioning properly. It is primarily used by computer enthusiasts and hardware manufacturers to test the stability and reliability of a system by subjecting it to a high level of stress.
Prime95 includes a feature called torture test, which puts the CPU and memory through a series of intensive calculations in order to determine if they are stable and can operate without errors. The program can be configured to test for a specific amount of time or until an error is encountered.
Prime95 is primarily used to test the stability of a computer's hardware and ensure that it is running at its optimal performance. It is also often used to troubleshoot issues with a system's hardware or to test the performance of a system before overclocking it.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
