OCCT hasn't gone fully commercial !

All features, except the test report in png format, are still available in the free version !

OCCT has been around since 2003, free to use except for professionnal users. This scheme worked to the extend of covering hosting costs, and purchasing license and test hardware for developing OCCT. However, at the time i write this, OCCT has not been making a penny for its authors.

To encourage everyone to participate in the OCCT adventure, we introduced a very cheap license system so that you can show your support to OCCT.

Please review the prices below and help us in developing OCCT !

To those who donated before, HOLD ON ! We are going to review past donations and send licenses according to what you paid before, as a token of thanks !

CALL FOR TRANSLATIONS

As OCCT was rewritten from scratch, we need kind souls to translate OCCT. Everyone that sends me a translation in a language not yet supported by OCCT will receive a Perpetual license for free !

How to translate OCCT

Translating OCCT is easy. First, download the english translation file : English.lang . Save it next to OCCT.exe and rename it to the language you're going to translate OCCT to.

Edit it using your favorite text editor ( i like Notepad++, but any will work - make sure you keep UTF-8 as the encoding though).

The first line says : <Language Name="English"> . Replace "English", obviously.

You'll then find the block for the language codes supported by this translation. Just list whichever language code applies to your translation. These are used by OCCT to automatically load your language file on startup, by matching this code with Windows's display language. For instance, here is the French language code list :

<LanguageCodes>
<LanguageCode>fr-FR</LanguageCode>
<LanguageCode>fr-BE</LanguageCode>
<LanguageCode>fr-CA</LanguageCode>
</LanguageCodes>

You'll find a list of language codes here. Look at the last column.

Then, it is just a matter of replacing every string by its translation. When you're done, start OCCT, and your translation will be available in the option menu (the gear icon). Test it, and send it to support@ocbase.com

FAQ

Which test is the best at detecting hardware errors ?

CPU:OCCT, Large data set, with Auto number of threads is, hands-down, what will detect CPU/Memory/Motherboard stability issues faster. Use GPU:3D DX11 and fullscreen for GPU testing, and Power supply for testing your PSU. Most errors are detected within the first 5 minutes. However, i recommend doing at least a 1 hour long test just to be sure.

Which test puts the most stress on the CPU ?

CPU:LINPACK at 90% memory is the most stressful test you'll find (use the latest version supported by your CPU - 2019 is best)

Starting at how many errors do you consider a computer unstable ?

Seriously : One.

Do I have to purchase OCCT to know where the errors come from ?

No ! The Free version has always been designed to be usable "as is". OCCT isn't witholding information from you (I would call that stealing). It detects errors, but can't tell you where they come from. On the software point of view, it is as if it asked the for 2 + 2 and got 5 as an answer.

• It is because the CPU miscalculated and answered that 2 + 2 = 5 ?
• Is it because the memory stored a 3 instead of a 2 ?
• Is it because when transferring the 2 from the memory to the CPU, the 2 got transformed to a 3 ?

As there's no sure way of reproducing the error that occured, there's no way of knowing what is going on. To further pinpoint errors, you have to dig yourself : lower the CPU frequency a notch and see if things are going better, up a voltage very carefully and see if it holds better... and pinpoint where the errors comes from. If you have access to spare parts, it is even easier to diagnose : replace and see what's going on.

I lost my license : how can I get it back ?

Send an email to support@ocbase.com and please give us at least a day for sending you your license back.

I am not using OCCT in a commercial or professionnal environment, yet my computer is joined to a windows domain. Can i run OCCT ?

Only the PRO version of OCCT will accept to launch on a computer joined to a windows domain. This is meant at detecting uses in professionnal and commercial environment, as they heavily rely on Windows domain. In the past, as there are enthousiasts that have a Windows domain at home, we offered a way of disabling this check as they were indeed not in a commercial environment, but this saw too much abuse. About 90% of the requests were from people trying to avoid the PRO license entirely. We thus removed that possibility, and you indeed need a PRO license now to run OCCT on a computer joined to a Windows domain.

Changelog
