64-bit is strictly required. 32-bit operating systems are completely unsupported by modern versions of AspenTech software.
Using inadequate hardware leads to slow convergence times, software crashes, and system freezes. This guide details the minimum, recommended, and optimal system requirements for Aspen HYSYS, ensuring your workstation delivers maximum performance. Aspen HYSYS Version Compatibility

Note for Mac Users: If you use an Apple Silicon (M1/M2/M3) or Intel Mac, you must run Aspen HYSYS through a virtual environment like Parallels Desktop running Windows 11 ARM/x64, though a native Windows workstation is highly recommended for stability. 2. Processor (CPU) Requirements Aspen Hysys System Requirements
One of the most common mistakes is confusing "minimum" with "adequate." The table below shows three distinct tiers for different use cases:
* Computer and Processor: Intel Core-i5 family 2.8 gigahertz (GHz) or faster. Memory (RAM): 8 GB 1. Free Hard Disk Space: 80 GB 1. Aspen Plus Minimum System Requirements | PDF - Scribd
Modern versions of Aspen software require a minimum of 16 GB of RAM and a multi-threading capable processor, with serious projects ideally using workstations with 32+ GB of RAM. 64-bit is strictly required
32 GB RAM (Essential for handling large-scale refinery models or running multiple instances of HYSYS simultaneously).
HYSYS does not scale linearly with cores. A 64-core workstation may be slower than a 16-core workstation due to inter-process communication latency. For most dynamic simulations, clock speed > core count.
Intel Core i7 / i9 or AMD Ryzen 7 / 9 (8 or more cores, 3.5 GHz+ clock speed). This guide details the minimum, recommended, and optimal
Windows Server 2019 and 2022 Standard/Datacenter editions (For multi-user network license servers and remote desktop environments).
Below are the hardware and software specifications based on the latest versions (V14, V12, and V14+).
Note: Home editions of Windows are not officially supported by AspenTech and frequently experience installation errors due to missing administrative and networking components. 2. Hardware Requirements: Minimum vs. Recommended
Unlike CFD (Computational Fluid Dynamics) software, HYSYS does use GPU for solving equations. A $1,500 Quadro is wasted money for pure solver performance.
Aspen HYSYS does not run natively on macOS or Linux. Apple Mac users must utilize Boot Camp (on older Intel Macs) or virtualization software like Parallels Desktop running Windows 11 ARM (though emulation may cause minor performance drops). 2. Database and Framework Prerequisites
