Tool checks whether reactivating stream processors on AMD cards is possible

It is sometimes possible to activate deactivated stream processors in recent AMD graphics cards. With a tool called CUInfo, which was written by tx12, a member of the Overclock.net forum, it is possible to check whether the gpu can be unlocked.

The tool reads information from the three recent AMD GPUs ‘Fiji’, ‘Tonga’ and ‘Hawaii’ about which compute units or stream processors within the compute units have been made active or unusable. It is not possible to unlock the cu’s via the tool. This has to be done in other ways, such as flashing the BIOS of the gpu. CUInfo scans which shader engines on the gpu are fully functional, which are hardware locked and which are software disabled. The software-disabled stream processors can then be switched on again, of course at your own risk.

Via the output of the scan you can check which shader engine is involved. Unfortunately, AMD uses two different ways to apply the hardware lock; in some cases the connection has been physically cut with a laser. Software-locked cards should at least be unlockable. In that case there are o’s.

There are also several posts on the overclocker forum about the different releases of the GPUs. Kitguru, for example, reports that not every Radeon R9 Fury can be flashed to a Radeon R9 Fury X, because the rest of the cu’s are physically disabled.

Update at 5:18 p.m.: It is an update of the 2013 tool called ‘Hawaii Info’. Thanks to Spekkie88 for reporting.
