UPDATE: Driver availability information can be found here.
We would like to take this opportunity to provide some advice on Windows compatibility with the Clarett interfaces. If you already have a PC with a Thunderbolt 1 or 2 port fitted as standard, it will most likely be ready to use once we are ready to release the proper drivers for Windows (please note that Thunderbolt 3 connections are not yet supported as we're aware of some potential problems when using this connection).
However, if you plan to buy a PCIe card to obtain Thunderbolt connectivity, you will need to find a card which is compatible with your motherboard. Not all motherboards have the capability for Thunderbolt expansion, you'll need a spare PCIe slot and a Thunderbolt 'header'. Please consult your motherboard vendor or PC manufacturer for details on which card to buy and how to install and configure appropriately as Focusrite may not be able to support you with this.
Due to the vast range of possible hardware combinations, our approach for Thunderbolt support on Windows is to qualify specific systems. We have qualified the following machines as working with the Clarett Thunderbolt driver using Thunderbolt 2 ports:
- HP ZBook (Thunderbolt 2 port)
- Molten Technology Intel X99 based machine (Thunderbolt 2 expansion card)
NOTE: we have also been testing the driver with a Lenovo Thinkpad W541 and have seen problems. We would therefore not recommend this machine for use with the Clarett range. There are also slightly newer iterations of the HP ZBook (the 'G3' model) with Thunderbolt 3 ports - please note that we do not support Thunderbolt 3 connections at the time of writing and can only recommend using models with Thunderbolt 1 or Thunderbolt 2 ports.
Here are some options for machines equipped with Thunderbolt 1 and Thunderbolt 2. Please note all of these listed in the included links have not been tested but are provided to help find alternatives that may work.
Unlike USB or Firewire protocols, Thunderbolt hardware and drivers require approval from Intel and Apple. Our assertion is that once we have a fully tested driver it will work with all other approved Thunderbolt systems. Although we would like to, it is impossible for us to test every Thunderbolt ready PC in the field, which is why we need to rely on this assertion to a certain extent. However based on this, in theory the Clarett's should currently work on any approved Thunderbolt equipped PC with a Thunderbolt 1 and 2 port (Thunderbolt 3 support is currently in progress and we will update this article when it's supported).
