Modern versions of Aspen HYSYS only run on 64-bit operating systems.
A Solid State Drive (SSD) is mandatory. Standard Hard Disk Drives (HDDs) result in agonizingly slow software loading and file saving times. NVMe M.2 SSDs offer the best performance. Graphics Card (GPU)
NVMe M.2 SSD with 1 TB+ capacity. This ensures rapid software boot times, fast loading of large .hsc files, and quick autosave performance. 5. Graphics Card (GPU) Requirements

If your computer runs out of RAM while HYSYS is solving a massive flowsheet, Windows will resort to using your hard drive as "virtual memory." This causes the software to crawl or freeze. Aspen Hysys System Requirements
For optimal performance, AspenTech recommends the following system configuration:
2560 x 1440 (QHD) or dual-monitor setups.
Minimum of free space for the core HYSYS installation.
Note for Mac Users: If you use a Mac, you must run Aspen HYSYS via a virtual machine (like Parallels Desktop or VMware Fusion) or Boot Camp (on older Intel Macs) configured with a valid Windows Professional license. 2. Hardware Requirements: Minimum vs. Recommended Modern versions of Aspen HYSYS only run on
A dedicated GPU smoothly drives dual or triple 4K monitor setups, which are highly useful for keeping your PFD, equipment workbooks, and strip charts visible simultaneously. 6. Software Prerequisites and Licensing
Insufficient RAM will cause your system to utilize the hard drive as virtual memory (paging), which slows down simulations exponentially.
The CPU is the most critical component for chemical process simulation.
Will you be running simulations or heavy dynamic simulations? NVMe M
Intel Core i7, i9, or Intel Xeon processors with higher clock speeds (3.0 GHz+).

The baseline for professional engineers working on standard plant designs.
Never install Aspen HYSYS on a traditional mechanical Hard Disk Drive (HDD) if you can avoid it.
If you plan to use the mode (time-dependent simulation), hardware requirements increase:
