This thread is 2 years old! Do not use these drivers either blockchain drivers both are obsolete! Use the latest Adrenaline drivers or those what your miner recommends and switch it to compute workload!

From what I recall, you have to use these drivers if you want to mine with Windows 7. The latest AMD drivers version which support compute mode is only for Windows 10, there is no option to enable compute mode on Windows 7.
Even if you toggle the hotkey in Claymore to force it into compute mode, it won't work with Windows 7.
This is why its recommended to upgrade to Linux or Win 10, since another issue with Win 7 is that 4 GPUs are max. You can't use more than 4 GPUs which are the newer RX unlike the older Tahiti/Hawaii GPUs.
