TurboSFV x86/x64
The key feature of TurboSFV is the calculation of file hash values. This can be a processor-intensive task in case of complex hash algorithms. The performance mainly depends on the used algorithm and its implementation, the CPU architecture and, finally whether the software is 32-bit or 64-bit compiled.

Newer hash algorithms are based on operations with 64-bit integers: An implementation designed for a 32-bit CPU suffers from the bitness of the processor registers. Additionally, the smaller number of registers impacts the performance.

A 64-bit CPU eliminates these limitations by offering the following characteristics:
  • 64-bit wide registers, which can keep 64-bit integers
  • Additional general purpose registers which can be used to save intermediate results
  • CPU instruction set which is designed for 64-bit operations.
The capabilities of the 64-bit architecture are only available for 64-bit applications, that's why TurboSFV has been ported to 64-bit. Starting with version 3, TurboSFV (PE/CE) now comes in two versions:
  • As a 32-bit (x86) version with native 32-bit code, designed to run on a 32-bit CPU.
  • As a 64-bit (x64) version with native 64-bit code, designed to run on a 64-bit CPU.
TurboSFV x64 uses the capabilities of a 64-bit CPU, you will notice significant speed improvements and/or less processor usage, especially for algorithms from the SHA-2 family. Note that
  • the x86 version requires the 32-bit version of Windows. You can't run the x86 version in the x86 emulator of Windows 64 (WOW64).
  • The x64 version needs a Windows 64-bit operating system.
Core
  • Parts of the code changed or rewritten to meet the 64-bit requirements. Changes affect in particular
    • all shell extensions (context menu, infotip, property sheets for hash files and hash calculation), because the Explorer under Windows 64-bit needs a corresponding x64 version for the integration,
    • all available hash functions (CRC-32, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256), because they especially benefit from the capabilities of a 64-bit CPU.
  • Code adjusted which reads from or writes to the registry, including the registration of the used file extensions: sfv, md5, sh1 und sh2.
Fixes
  • The character which separates the digits in the progress indication is now a hardwired dot.
  • The window which pops up for the creation of hash values now always starts in the foreground.
Interface
  • Manuals updated.
Installation notes
  • If you have previously installed TurboSFV version 2 or an older version, then you must manually uninstall the older version either via the control panel or via the shortcut in the windows menu - before starting the setup of version 3. Different versions of TurboSFV on the same system may result into problems.
Upgrade information
  • The registration keys for version 2.x are no longer valid. Existing customers can upgrade to the current version for free by sending an e-mail to the address below, if you can provide the following information:

    • Registration ID as indicated in the same window. Do not send your personal registration key!
    • The e-mail address which you have used for the purchase.

    E-Mail:  tur
    es@bos
    salfv.com

    Version 3 registration keys register both, the x86- and the x64 version. Remember that the registered version (x86 or x64) shall only be installed and used at the same time on one computer and by one person - as described in the license agreement.

This offer is no longer valid.
