Recommended system requirements

  • Processor type: Intel i7 10th generation or above
  • Installed RAM: 12 GB RAM or above
  • Solid-State Drive with available capacity: 256+ GB SSD Storage
  • Screen: landscape widescreen monitor with 1366 × 768 and up

Recommended bandwidth

It is difficult to provide a recommended bandwidth because of the nature of the Internet and individual corporate usage. Network latency, peering issues, bandwidth at upstream providers, users using their Internet connections for other uses besides CCH iFirm, etc. all affect the perceived performance of the connection and the amount of bandwidth required to keep performance adequate. We have found through working with customers that e-mail (business and personal), e-mail attachments, news, streaming music and videos, put a much greater strain on the available bandwidth. Therefore, we recommend that customers measure all activities to make sure they are evaluating a holistic demand on their network services. If you plan to use CCH iFirm Portal and CCH iFirm Documents, you should take into account the number of files you will download or upload as well as their size.
