TT System Requirements Documentation

Hardware and Operating System – XP Professional

OS and Service Pack

TT recommends all client machines be installed with Windows XP and SP1 or higher.

Note: The following operating system combinations are supported for a Japanese X_TRADER® machine:

  • Japanese Windows XP Professional
  • Non-Japanese Windows XP Professional running an East Asian Language Pack set to the Japanese language

NIC Configuration

  • Ethernet cards must be on the latest driver version.

    Note: Per internal testing, TT has found that Nvidia cards can introduce random latency and disconnects.

    Note: Due to driver and firmware limitations, TT does not recommend using Broadcom NetXtreme I based Ethernet cards in a production environment. Instead TT recommends the Broadcom NetXtreme II Gigabit cards, with either Broadcom driver version 14.2 or higher or HP driver 5.2.17 or higher.
